BOOSTER SETS GHV SERIES GENERAL INTRODUCTION - PRODUCT DESCRIPTION Lowara GHV series booster sets are designed to transfer and increase the pressure of water, in the following applications: Hospitals Schools Public buildings Industries Hotels Condominiums Sports facilities Mains water systems GHV series booster sets are pumping stations assembled with two up to a maximum of four vertical multistage pumps from the e-sv series. The pumps are connected to one another by suction and delivery pipes, and fixed onto a single base. The pumps are connected to the manifolds by means of stop valves and check valves. An electric protection and control panel is installed using a bracket on the base of the set. GHV series booster sets offer different regulating possibilities and are divided into the following versions: GHV Multi - Master series Pressure boosting sets with 2 to 4 e-sv series pumps, with Hydrovar Master-type frequency converters for each pump located on the booster set. Variable speed operation is possible on all pumps turning at the same speed. GHV Master + Basic series Pressure boosting sets with 2 to 4 e-sv series pumps, with Hydrovar Master-type or Basic-type frequency converters for each pump located on the booster set. Further details on page 1. Variable speed operation is possible on all pumps turning at the same speed. GHC Cascade control series Pressure boosting sets with 2 to 4 e-sv series pumps, one single pump equipped with a Hydrovar frequency converter. Further details on page 16. All the other pumps kick-in depending on system requirements and run at fixed speed. The constant pressure is maintained by adjusting the speed on the Hydrovar pump. Systems for regulating the speed of the electric motors, as in GHV series booster sets, are used in the following cases: In the case of systems with a lot of users where the daily consumption varies frequently and in different periods. When it is necessary to obtain constant pressure. In the case of systems with supervision it is possible to monitor and check the performances of the pump stations. Systems for regulating the speed of the electric motors, as in GHV series booster sets, are used in the following cases: In the case of systems with a lot of users where the daily consumption varies frequently and in different periods. When it is necessary to obtain constant pressure. In the case of systems with supervision it is possible to monitor and check the performances of the pump stations. These types of systems improve comfort for the final user, reducing noise output and guarantee the reduction of the so-called water hammer, thanks to the gradual switching off of the pumps. 3
BOOSTER SETS GHV SERIES DESCRIPTION OF OPERATION In Lowara GHV series booster sets all pumps operate at variable speed. The pumps are connected to a frequency converter assembled directly on the motor fan cover. All pumps, to a maximum of four, engage by means of their own frequency converter. The pumps start automatically depending on the system requirements. Each pump is fitted with a pressure transmitter that is required to detect the pressure variation. The recorded figure is transmitted to the frequency converter. The pump driven by the inverter modulates its speed according to the system demand. The alternating pump start takes place automatically whenever the system is started and at pre-set timings. Starting and stopping of the pumps is determined according to the set value of pressure in the frequency converter menu. Example of operation of a set of three GHV series pumps. The pumps are controlled by each frequency converter connected directly to the pump electric motor; at every new starting cycle of the pumps, the starting priority of the pumps changes. The speed adjustment will be for all installed pumps. All the pumps will turn at the same speed. When the demand for water decreases, the pumps will stop in cascade. The pumps connected to the frequency converters keep the pressure constant by modulating the number of motor revs. At start and stop all pumps have a soft acceleration and deceleration. This allows to reduce water hammers and provide low booster set noise output. Example of operation of a set of three GHC series pumps. One pump is controlled by a Master-type frequency converter connected directly to the pump electric motor. The other pumps are controlled by an external ON/OFF signal and run at fixed speed. Speed adjustment happens only for the pump connected to the frequency converter. The other starting pumps use the contactors in the electric panel. The pump connected to the frequency converter will start first, while the other pumps will follow. For the latter it is possible to have the automatic alternating start in order to distribute the working load evenly. When the demand for water decreases, the pumps will stop in cascade. The last to stop will be the inverter pump. The constant pressure is maintained by adjusting the speed of the first pump. Lowara GHV series booster sets guarantee constant pressure of the system as in the following example: H Set pressure Q 4
BOOSTER SETS GHV SERIES DESCRIPTION OF OPERATION When there is a demand for water, the pump controlled by the converter will start, positioning its speed to guarantee the set pressure value. When the demand for water increases, the other pumps will start operating at variable speed and with the same speed value in order to maintain a constant pressure. H Set pressure When the demand for water decreases, the pumps switch off in cascade and the first pump decreases the number of revs to a set minimum before switching off definitively. Regulating the constant pressure value GHV series booster sets guarantee constant pressure of the system even during frequent variations in water consumption. When the booster set is connected to the system, the pressure value is read through the pressure transducers fitted on the delivery manifold. The value found is compared with the set value. The check between the pressure value found and the set value is made by means of the Hydrovar internal controller that manages the motor acceleration and deceleration ramps (frequency), modifying the pump performance over time. In case of malfunction of one of the frequency converters, the other will continue to stay active and guarantee the control of the other pumps as well as maintain a constant pressure. Type of control GHV series booster sets use a sensor as a standard device to control pressure. For each booster set the sensor number is the same as the number of installed pumps. In case of fault in the transducer the converter connected to the pump stops operating. It is possible to change the measuring unit as bar, psi, m 3 /h, C, F, l/sec, l/min, %. In this case it is possible to use different transducers depending of the selected measuring unit, such as flow and temperature transducers. Setpoint It is possible to select up to two setpoints of different values. Thus it is possible to use the booster set to serve systems that require different user pressure values. For example, different setpoints can be used for an irrigation system on a hillside, or one setpoint value can be used for domestic water supply during the day and a second setpoint for irrigation at night. The setpoint changes can be made using an external device. Q
BOOSTER SETS GHV SERIES DESCRIPTION OF OPERATION Cyclical exchange of pumps Cyclical exchange of pumps is available for both the GHV and the GHC series. For the GHV series the pumps equipped each with its own drive alternate the start at every system restart or at a given time set for each pump by means of an internal clock in the drive menu. For the GHC series, the cyclical exchange takes place only for fixed-speed pumps that are controlled by their dedicated electric panel. The pump connected to the drive always starts first. Protection against dry running The protection function against dry running intervenes if the water reserve to which the booster set is connected falls below the minimum level guaranteed for suction. For GHV series booster sets the level may be controlled by a float, level probes or minimum pressure switch. It is also possible to manage the function directly by imputing a minimum pressure value in the Hydrovar control board menu, which will receive a signal from the pressure transducer. 6
BOOSTER SETS GHV SERIES CHOICE AND SELECTION The following conditions should be considered when choosing a booster set: The system s requirements should be met regarding flow rate and pressure. The booster set must not be oversized, avoiding unnecessary installation and running costs. Generally water distribution systems such as those for domestic water supply or for large agglomerates such as hospitals, hotels or similar, have variable water consumption i.e. in a 24-hour period there may be sudden variations in consumption that are difficult to foresee. A pattern of consumption may occur in 24 hours, but the daily percentage of booster set operation may also occur at various flow rates. Generally the definition of flow rate for these types of systems is based on either the probability calculation which is a very complex system of calculation, or based on tables or diagrams in the national standards which provide guidelines for the sizing of the systems and therefore for calculating the maximum simultaneous flow rate. Q (m³/h) 4 3 2 1 3 6 12 9 1 18 21 24 hours Consumption--over 24 h The operating time of the booster set, still calculated over 24h, gives us a view of the daily percentage of operation at the various flow rates. This means that there may be daily peaks where the maximum flow rate requested is concentrated in a short space of time. In the example given below, it can be seen that in 1% of the time there is a consumption of 4 m³/h, while in 2% of the operating time there is a consumption of 4 m³/h. Q (m³/h) 4 3 2 1 2 7 1 % hours/day Operating time 7
BOOSTER SETS GHV SERIES CHOICE AND SELECTION When selecting the booster set the consumption figure of the system must be considered, which is generally supplied by the person who designed the system. For systems where consumption varies continuously and suddenly over time it is advisable to install GHV series booster sets with variable regulation of the pump speed. The calculation of the size of the booster set (its performance and the number of pumps) is based on the take-off point and therefore on the consumption value which takes the following factors into account: The value of the peak in consumption Efficiency NPSH Standby pumps Jockey pumps Diaphragm tanks By adjusting their operation over time, variable-speed booster sets give the end user energy savings which can be calculated directly on the control board with a metering module fitted in the electric panel. This allows checking of the system efficiency, especially in complex systems with many users and many ranges of consumption. It is possible to install a standby pump if it is necessary to have some kind of additional safety in the pump station. This is typical in systems of a certain importance, such as hospitals or factories, or in the field of crop irrigation. If small users have to be served in the same system, it is preferable to install what is commonly called a jockey pump, where instead of running the main pump, which usually has higher power, the service is guaranteed with a smaller pump and therefore lower energy consumption. GHV series booster sets must also be equipped with diaphragm tanks (for the size of the tank, see the specific chapter in this catalogue). A single tank can be installed on the delivery side of the booster set, or smaller tanks, maintaining the same total volume. Diaphragm tanks avoid the risk of water hammer, which is harmful for both the system and the pumps. Generally for systems with highly variable or sudden variations in consumption, it is recommended to install a booster set with variable pump speed, such as the GHV series, to guarantee constant pressure. SELECTING THE PUMPS What type of pump to choose? Generally, the choice of pump is based on the take-off point of the system, which is usually the highest possible. The maximum request value is normally for short periods, so the pump must also be able to satisfy variable requests throughout its time in service. 8
BOOSTER SETS GHV SERIES SELECTING THE PUMPS Generally the choice of the pump, based on the performance curve, should fall around the maximum efficiency point. The pump must ensure operation within its rated performance. Since the booster set is sized according to the maximum possible consumption, the take-off point of the pumps must be in the area on the right of the performance curve so that, if there is a fall in consumption, the efficiency remains high. η Recommended range Pump performance curve Q If we make a choice on the characteristic curve of the pump, we can see that the area where it is best to select the pump is represented by the following graph: H Recommended selection area Q Another factor to be considered when choosing the pumps is its npsh value. Never choose a pump where the takeoff point is too far to the right of the npsh curve. This risks not having good pump suction, which may be aggravated by the type of installation (where negative suction is possible). In these cases there is the risk of cavitation. The npsh of the pump must always be checked at the maximum flow rate requested. npsh Recommended range Npsh curve Q 9
BOOSTER SETS GHV SERIES SELECTING THE PUMPS The choice of pump is therefore based on the characteristic curve of the pump depending on the flow rate and the pressure required for the system. Starting from the required flow rate, a vertical line is drawn until it meets the horizontal line of the required pressure. The point of intersection of the lines gives both the type and the number of pumps necessary for the system. 22SV1 ISO 996 - Annex A 1 2 3 4 18 1 2 3 4 16 14 12 4 The example alongside refers to a required flow rate of 6 m³/h and a pressure of 11 water column. 1 8 3 As may be seen from the selection, the system requires three pumps of the type 22SV1 as indicated top left in the table. 6 4 2 1 Moreover the take-off point falls in the npsh area farthest to the left and therefore in an area with a low cavitation risk. 2 6 4 1 NPS 1 2 2 4 6 8 1 12Q [m 3 /h] 14 1 1 Q [l/min] 2 7782_A_CH The values obtained are those for the performance of the pumps. A correct check of the net pressure value must be made due to the intrinsic load loss of the booster set and the conditions of installation. For this reason it is recommended to see the specific chapter in this catalogue. 1
BOOSTER SETS GHV SERIES CALCULATING NET PRESSURE SURE When selecting the GHV series of pressure booster units, reference must be made to pump performance. Performance is calculated from the characteristic curves of the pumps and does not consider any pressure drops generated by pipes and valves as in the pressure booster units. To help choose the right pressure booster unit and calculate the correct pressure at the delivery manifold, the following example is shown: given the duty point Q = 42 m 3 /h H = 1 mca and with two pumps working, the pump with the most suitable characteristic curve is chosen, that is, the one with a curve that guarantees the required flow and head values. 22SV1 ISO 996 - Annex A 1 2 3 4 18 16 14 12 1 8 1 2 3 4 4 3 From the example, we have chosen the 22SV1 series pump which guarantees system performance. The pump curve is slightly oversized, but this provides a safety margin to counter the pressure drops in the pressure booster unit pipes. To know the effective pressure at the delivery manifold outlet, the pressure drops in the suction and delivery lines of each pump are calculated. 6 4 2 6 4 2 1 1 1 NPS To simplify calculations, the pressure drop curves for each pump, on page 113 of this catalogue, are used. Assuming a pressure booster unit with check valves on the suction line (curve B of Hc pressure drops) has been selected, one proceeds as follows: 2 2 4 6 8 1 12Q [m 3 /h] 14 1 1 Q [l/min] 2 7782_A_CH The Hc pressure drops on the pump suction line are to evaluated on the B curve. At a flow rate of 21 m 3 /h the value of Hc = 2,8 m. Similarly, the Hc pressure drops on the delivery line of the pump, as evaluated on the B curve, are analysed. At a flow rate of 21 m 3 /h, the value of Hc is,3 m. The total pressure drop on the delivery and suction lines is therefore 2,84 m. As regards the pressure drop in the suction and delivery manifolds, % with respect to the pressure drops in the pump suction and delivery can be considered. In this case, therefore, the value is,142 m. The total pressure drop is approximately: 3 m. Analysing the performance of the unit at a flow rate of 42 m 3 /h, the head H is 11 m. The net pressure at the delivery manifold is 11 3 = 112 m. Comparing this value with the rated value, 112 m > 1 m. The unit can therefore satisfy the demand of the system. 11
BOOSTER SETS GHV SERIES SUCTION CONDITIONS The above example does not consider the suction conditions of the pressure booster unit which, similarly, affect final performance. It is therefore always best to check the suction line for leaks, especially as regards positive head installations. An example of positive head installation relative to the above case is shown below: In the positive head installation, the designer must calculate the minimum installation height Hg of the pump in safety conditions in order to avoid cavitation and, therefore, de-priming of the pump. The relationship that must be checked and which connects this measurement is the following: NPSH available NPSH requested where equality is the limit condition. NPSH available = Patm + Hg - pressure drops. Where: Patm is the atmospheric pressure, equal to 1,33 m Hg is the geodetic difference in level The pressure drops are connected with to the suction piping and relative valves (foot and cut-off valves) NPSH requested is a pump parameter taken from the performance curve of the pump which in our case, at a flow rate of 21 m 3 /h corresponds to 2, m. Before calculating the NPSH available, the suction pressure drops are calculated using the tables on pages 131-132 in this catalogue, considering a material such as steel. The chosen diameter of the suction piping is DN8. 9 curve DN8 = 2,11 m Damper DN8 =,28 m Drain valve DN8 =,3 m (calculated from supplier data) Piping DN8 =,61 m (assuming a length of 2, m) Piping DN8, intake manifold =,4 m (length of manifold,61 m) Pressure drops on pump suction side (curve B) = 2,8 m pressure drops = 6,1 m Remembering that: NPSH available = 1,33 + Hg - 6,1 Replacing: 1,33 + Hg - 6,1 2, Hg = 2, + 6,1 1,33 = - 1,73 m representing the limit, for which reason: NPSH available = NPSH requested Generally speaking, therefore, in order to assure correct operating conditions as regards the risk of cavitation, the pump must be positioned above the level of the tank so that the suction height is lower than the limit value of 1,73 m. 12
BOOSTER SETS GHV SERIES INSTALLA ALLATION GHV series booster sets must be installed in areas protected against frost and with adequate ventilation to cool the motors. It is good practice to connect the suction and delivery pipes with vibration-damping joints to limit vibrations and resonance in the whole system. Delivery anti-vibration joint Suction GHV series booster sets must be connected to pressurised tanks with an adequate capacity for the system. These tanks can avoid any problems due to water hammer that is created due to the sudden stopping of the pumps running at a fixed speed. For this type of system, 24-litre diaphragm tanks can be used that perform a pressure dampening function, since they do not have to provide water storage like ordinary autoclave systems. Due to their design, variable-speed booster sets can satisfy users demands by moderating the pump speed. It is always recommended to check the type of system to be made and choose the correct capacity of the diaphragm tank accordingly. For the sizing of the diaphragm tanks, see the specific chapter in this catalogue. Considering also that variable-pressure sets are very sensitive to swings of pressure in the system, the use of diaphragm tanks allows the pressure to stabilise when requests are low or inexistent, and avoids the pumps remaining in operation at minimum speed without stopping. It is good practice to check the value of the maximum pump pressure to match the set with a tank suitable for the pressure value. Suction Delivery 13

VARIABLE-SPEED PUMP SYSTEMS From a mechanical standpoint, the Module concept related to HYDROVAR AR is divided in two parts, the motor assembly power unit (power unit) and the control board. In the basic configuration, that is with a single motor assembly, HYDROVAR may be used as Basic Unit (BASIC) without having to use a control board. In this configuration HYDROVAR may be used as a sequential pump in a multi-pump system with at least one master inverter. By expanding the Basic inverter with the additional control board and the LCD screen, the HYDROVAR Master Unit becomes suitable to operate in different modes and may be expanded by implementing several modules. GHV VERSION, MASTER + BASIC SERIES This mode provides several different combinations of different HYDROVAR versions. In general, each pump is equipped with a HYDROVAR unit. Each pump in the system (which may count up to 8 pumps), is fitted with a HYDROVAR unit (at least one as Master unit and the others as Basic units, to guarantee adequate system control); the units are connected one another by means of a serial interface. Minimum requirements: one Master unit and the others equipped with Basic unit. The entire control process takes always place by means of the Master unit, though it is also possible to alternate the standby pump sequence in order to distribute wear and allow for the same number of operating hours of the pumps controlled by basic inverters. Following versions are available: Power size above 2,2kW up to 11 kw motor mounted.

MAIN CHARACTERISTICS S OF FREQUENCY CONVERTERS USED IN THE BOOSTER SETS GHV,, GHC SERIES The GHV, GHC series booster sets use a Hydrovar frequency converter, an automatic device that adjusts the speed of the electric pump in order to maintain constant pressure in the system. Converters with power up to 22 kw can be mounted directly on to the motor. Models up to 22 kw can be mounted alternatively on the wall if equipped with the optional fan kit. Models with over 22 kw power, up to 4 kw, are designed for wall mounting only. The pressure is measured by a pressure transmitter which uses a standard 4..2 ma signal. The system pressure value can be read on the converter s display. A simple user interface allows you to set the desired pressure value for optimal adjustment, as well as to view the operating data, such as the hours of operation and any alarms triggered. Included diagnostic menu to view temperature, current and voltage values of Hydrovar facilitates diagnostics and failure analisys. Indicator lights signal power status, pump running and malfunctions. A password is required to access sensitive settings that allow you to configure the converter in order to adapt it to any control requirements, such as flow resistance compensation, external control, periodic testing and so on. When more than one pump is used, the converters exchange information with each other through an RS48 serial line which can connect up to 8 Hydrovar devices plus one external unit for remote control. The Pump-link and Pump-watcher dedicated systems, connected to Hydrovar, allow remote control with a mobile or landline telephone system. RS48 serial interface available as standard up to 22 kw, which allows to control the Hydrovar converters from a Modbus field serial bus line. The converter is equipped with two potential-free relays which can be used for remote signalling of pump running and malfunction status, plus a programmable voltage analogue output for signalling the frequency or pressure. Standard version with two sensors inputs for implementing of two actual values signals within one system (min/max, difference) or for a second sensor for safety reasons. Specific digital inputs are used for protection against water failure, motor overtemperature, as well as for external enable signal and remote control. The converter also incorporates a dry running protection function via an adjustable minimum pressure threshold. Class A filter standard for Hydrovar three-phase power supply. E.g. Industrial areas, technical areas of any building fed from a dedicated transformer are examples of environment locations. Class B filter standard for Hydrovar single-phase power supply. E.g. Houses, apartments, commercial premises or offices in a residential building are examples of environment locations. Further information are available into Hydrovar manual.

ENERGY SAVING The worldwide demand for energy is growing all the time and, while the demand is increasing, production is coming up against serious problems of an environmental nature and related to the supply of raw materials. In other words, energy is an asset that is becoming more precious every day, imposing choices to optimise consumption, especially with a view to safeguarding the environment. A very important improvement role is played by new technologies which include, among the most desirable parameters, environmental protection and energy saving as well as best technical performance. Drives for electric motors fall into this category. As well as making a considerable contribution to the decrease in energy consumption and consequently to the improvement of the environment, in many applications they also produce a notable reduction in the overall costs of running the installations. Drives for Electric Motors The electronic drives that are most involved in the general improvement of the quality of systems and installations, are those for asynchronous alternating current motors, generally three-phase induction motors. They may be divided into two large categories: Drives with variable voltage Drives with variable frequency The first, called starters or soft starters, are appliances that operate at constant frequency (that of the power mains), dose the voltage supplied to the load and have limited current. The following figure illustrates the typical operation of the soft starter : V (volt) Vmax Current limit fig. 1 The second, called Inverters or frequency converters are most important from the point of view of energy saving and are able to supply the motor with a practically sinusoidal current (PMW) at a frequency that may vary from a value of practically Hz to a rated frequency and beyond, with a constant flow (torque) or constant power. Typical example, fig.2: t (sec) The applicatory advantages of the two categories of drives will be described below. V (volt) fig. 2 Softstart The direct starting of an asynchronous motor presents Vnom considerable difficulties due to the peak current in the start phase. Typically the value of the starting current is Constant power about 7/8 times the rated current of the motor. Direct start systems are therefore not generally convenient (except for small power); mainly because of Vboost the need to increase the size of the power supply mains Constant torque (switches, fuses, etc....), and also problems of a mechanical nature, due to high stress in the start phase which in the medium/long term may prove to be destructive. f nom f (Hz) The electrical engineering industry has already found various practical solutions to the problems; the main ones are noted below: Special motors with double winding Starting with autotransformer Star/delta starting These starting systems are certainly an improvement on direct starting, but they do not solve the problem. The advent of electronic starters ( soft starters ) made a decisive contribution to solving the question. 19
ENERGY SAVING This type of drive is able to supply performance advantages: Progressive start with a voltage ramp having a duration adjustable within wide time limits. Limited current start with a value that can be set from 1% to % of the rated value. Descending voltage ramp having a duration adjustable within wide time limits. Voltage ramps at starting and stopping adaptable to particular operations (pumps). Low-speed operation, with reversible running direction, for specific applications. Energy Saving function with automatic reduction of the voltage/current in the case of a prolonged underload. Safety devices that can be calibrated to prevent overheating of the motor, over/under currents and over/under voltages. Safety devices that can be calibrated to prevent prolonged or too frequent starts. Possibility of by-pass operation after starting, keeping all the safety devices active. All these features make the electronic starter the ideal tool for solving the problems we have mentioned. With the recently designed starters, with both analog and digital control, it is possible to obtain considerable softer and more efficient starts than any other electromechanical system was able to achieve. Moreover, thanks to the intrinsic control and protection systems of the starter, it is generally possible to eliminate other protection equipment that would otherwise be necessary in the system. In conclusion, in many applications, one can SAVE on: Structure and auxiliary equipment of the power supply system. Protection of the mechanical system against excessive stress. Speed Adjustment The speed adjustment systems allow energy consumption in proportion to the use of the system based on user demand. This allows considerable savings in systems working on a daily basis (24h). Alongside applications that require operation of the electric motors at a constant speed, with steady voltage and frequency, there are many in which the electric motor must be able to vary its speed of rotation (frequency); moreover, in many applications the process control obtained by varying the speed (adjustment of flow rate, pressure, etc...) is much more convenient than any other method of adjustment. For these applications the most suitable drives are certainly frequency converters, referred to below as Inverters, which can supply the motor with the desired torque from a few rpm up to the rated speed beyond which they are still able to operate at constant power with a decreasing torque. The advantage of using the Inverter lies in the greater efficiency of the performance that it is able to give in comparison with electromechanical controls. A useful application of frequency converters may simply be that of obtaining a soft start for a load that is particularly heavy to start (pump) and variable over time (flow rate). In any case the advantage of a soft start is present in all inverter-controlled systems for starting a motor, even in cases where speed adjustment is not needed. The advantage is due to the fact that the inverter is able to supply the rated torque (with possibility of 1% overload with respect to the rated current), right from frequency zero. This is possible because the voltage to the motor, generated by the inverter, is in phase with the number of revolutions right from the start (unless the motor is running). In this way the losses in the motor are considerably reduced. The starting torque that can be obtained using the inverter is greater than that obtained with a soft starter, and the demand for current in the whole starting phase is much lower. The yearly saving, for a lost power of 4 Kwh, with electromechanical start, may be as much as 2 Euro. The reliability and efficiency of the pump speed control systems means optimising consumption and processes as well as savings. In the specific case of pumping appliances, the immediate consequence of the use of these systems is the realisation of pumps with greater operative flexibility, with much larger and optimal performance curves. There are many advantages above all, a pump that always works, irrespective of variations in the installation, in optimal conditions with less wear and less malfunctions. So there are less problems from downtime and the pumps require less frequent maintenance. Moreover, an installation where the pumps are controlled by an inverter is more efficient and less subject to stress: absence of water hammer (which occurs when switching off pumps driven in a traditional way); lower working pressures than systems with an autoclave or piezometric tank; pressure and flow rate conditions always adequate for the demands, because the inverter is able to adjust the pump gradually in real time according to the pressure trend in the installation. 2
ENERGY SAVING All this results in less stress on all the components in the distribution network, and therefore in less maintenance of the network, greater reliability of supply and lower running costs. In short, using a pumping system with one or more variable-speed pumps means: Saving energy; Optimising resources and processes; Having the possibility of complete integration of the management, control and supervision systems; Prolonging the life of the installations; Reducing maintenance costs; Increasing the productivity and efficiency of an installation. Comparison of starting systems Having examined the various starting systems that can be realised for electric motors, direct start, star/delta, soft starter and inverter, they can be compared, analysing the absorbed currents and therefore the energy consumed (current = energy = kwh = MONEY) I 7 x I n Direct Starting I t Star/delta starting t 4 I n Starting with Soft Starter I I t I Starting with Inverter t 7 x I n Comparisons I n t 21

RUBBER EXPANSION JOINT KIT The anti-vibrating joints or compensation joints can be used in order to absorb deformations, expansions, noises in the piping and to reduced ram blows. Moreover they can resist a high degree of empty that allows the absorption of negative expansions for depression. Being of elastic material it can be become deformed and be dilated facilitating therefore the installation, that it becomes simpler and fast, also in which the piping they are not aligned. It does not need assembly joints.

DRY RUNNING PROTECTION SYSTEMS Dry run shutdown systems should be installed to protect the pumps in case of insufficient water supply. FLOAT SWITCH PROTECTION METHOD The float switch protection system is used when the water supply comes from open tanks. A float switch immersed in the tank can be connected directly to the frequency converter (GHV1 sets) or to the electrical panel for the GHV2, 3 and 4 sets. If the water supply is insufficient, the float switch opens the electric contact and the pumps stop running. Gcom-pms1_a_dd ELECTRODE PROBE PROTECTION METHOD The electrode probe protection system is used when the water supply comes from open tanks or wells. A set of three probes is connected directly to the electrical panel with control circuit (for GHV2, 3 and 4 sets). For single-pump sets (GHV1), an additional level control must be installed (probe module) which supplies an electric contact to be connected to the frequency converter. If the water supply is insufficient, the control circuit opens the electric contact and the pumps stop running. Gcom-pms2_a_dd MINIMUM PRESSURE SURE SWITCH PROTECTION METHOD ACCESSORIES SORIES The minimum pressure switch protection system is used when the water supply comes from water networks or pressurized tanks. The pressure switch is connected to the electrical panel equipped with control circuit (for GHV2, 3 and 4 sets). For single-pump sets (GHV1) the pressure switch is connected directly to the frequency converter. If the water supply is insufficient, the pressure switch opens the electric contact and the pumps stop running. OPTOELECTRONIC SENSOR PROTECTION METHOD (ONLY GHV) The optoelectronic sensor protection system is used to protect the pump by installing a sensor directly on the body of each pump.the device is mounted onto the fill plug using an adapter, if needed. The sensor is electrically connected to the frequency converter which powers it. The sensor cuts in if the water supply is insufficient or if there is air in the area of the pump body where it is positioned. For installations where lack of water is a normal condition when the pump is off, the control system must be equipped with a pump running electric contact. Gcom-pms3_a_dd Gcom-pms4_a_dd 12

WATER REQUIREMENTS IN CIVIL USERS Determination of the water requirement depends on the type of users and contemporaneity factor. The calculation may be subject to regulations, standards or customs that may vary from country to country. The calculation method shown below is an example based on practical experience, designed to provide a reference value and not a substitute for detailed analytical calculation. Water requirements in condominiums The consumption table shows the maximum values for each delivery point, depending on the plumbing amenities. MAXIMUM CONSUMPTION FOR EACH DELIVERY POINT TYPE CONSUMPTION (l/min) Sink 9 Dishwasher 1 Washing machine 12 Shower 12 Bathtub 1 Washbasin 6 Bidet 6 Flush tank WC 6 Controlled flushing system WC 9 G-at-cm_a_th The sum of the water consumption values of each delivery point determines the maximum theoretical requirement, which must be reduced according to the contemporaneity coefficient, because in actual fact the delivery points are never used all together. f = 1 (,87x Nrx Na) Coefficient for apartments with one bathroom and flush tank WC f = 1 (,87x Nrx Na) Coefficient for apartments with one bathroom and controlled flushing system WC f = 1,3 (,4x Nrx Na) Coefficient for apartments with two bathrooms and flush tank WC f =,8 (,727x Nrx Na) Coefficient for apartments with two bathrooms and controlled flushing system WC f= coefficient; Nr= number of delivery points; Na= number of apartments TECHNICAL APPENDIX The table of water requirements in civil users shows the maximum contemporaneity flow-rate values based on the number of apartments and the type of WC for apartments with one bathroom and two bathrooms.

WATER REQUIREMENTS FOR COMMUNITY BUILDINGS The requirements of buildings intended for specific uses, such as offices, residential units, hotels, department stores, nursing homes and so on, are different from those of condominiums, and both their global daily water consumption and the maximum contemporaneity flow rate are usually greater. The diagram of water requirements for community buildings shows the maximum contemporaneity flow rate of some types of communities, for guidance. These requirements must be determined case by case with the utmost accuracy, using analytical calculation methods, according to particular needs and local provisions. For seaside resorts, the flow rate must be increased by at least 2%.

USE OF BOOSTER SET Water is usually delivered by public supply systems and the pressure is generally sufficient for the proper operation of the users water and sanitary equipment. When this pressure is not sufficient, booster sets are employed to increase water pressure and ensure an acceptable minimum value at the furthest points. Therefore, the water supply to a building, group of buildings or to a system in general can be considered satisfactory when all the user points can deliver the required quantity of water. Set connection methods (intake side) Water can be supplied to a booster set in two ways: 1 - By installing a water storage tank between the user s offtake and the booster set (indirect connection, fig. 7.1.1). 2 - By connecting the booster set directly between the user s offtake and the system (direct connection, fig. 7.1.1). The indirect connection does not allow the water system pressure to be utilized. Therefore, it requires pumps with greater head. The direct connection allows the water system pressure to be utilized, provided the pressure fluctuation ( p) does not exceed 1 bar. If it does, a pressure reducer must be installed for proper operation of the booster set. INDIRECT UTILISATION SUPPLY USER S OFFTAKE WATER STORAGE TANK BOOSTER SET WATER PIPE UNDER PRESSURE (1) SUPPLY DIRECT PRESSURE REDUCER IF p > Ibar BOOSTER SET USER S OFFTAKE (1) BY PIPE UNDER PRESSURE WE MEAN A WATER SYSTEM, A CLOSED TANK, ETC. (2) IN THE CASE OF A WATER SYSTEM INSTALL A CHECK VALVE (A) OR A DISCONNECTING DEVICE (B), UNLESS OTHERWISE PROVIDED BY LOCAL REGULATIONS fig. 7.1.1 TECHNICAL APPENDIX 12
Water supply systems in civil buildings The configuration of the supply system must comply with the following conditions: - The minimum pressure ensuring the proper operation of the equipment must be guaranteed at the most unfavourable drawing point (1. bar for valves and flush tank WC, and 2 bar for controlled flushing system WC). - At the most favourable drawing point, pressure must not exceed bar. Once these parameters have been satisfied, in relation to the height of the building and to the set intake conditions, the water supply system can have one of the following configurations: SUPPLY SUPPLY A) THE SET SERVES THE ENTIRE BUILDING B) THE SET SERVES THE ENTIRE BUILDING, BUT THE LOWER FLOORS ARE CONNECTED THROUGH A PRESSURE REDUCER SINCE THE PRESSURE TO THE NEAREST UTILIZATION POINTS IS TOO HIGH fig. 7.1.2 fig. 7.1.3 TECHNICAL APPENDIX SUPPLY WATER PIPE UNDER PRESSURE BOOSTER SET SUPPLY WATER PIPE UNDER PRESSURE BOOSTER SET C) THE SET SERVES THE UPPER FLOORS, WHEREAS THE LOWER FLOORS D) THIS CASE RESEMBLES THE PREVIOUS ONE ARE SUPPLIED BY THE WATER PIPE UNDER PRESSURE EXCEPT THAT PRESSURE REDUCERS NEED TO BE INSTALLED ON SOME OF THE LOWER FLOORS fig. 7.1.4 fig. 7.1. 126
DETERMINING THE HEAD OF THE SET AND INTAKE CONDITIONS Level intake The delivery head of the set (H tot) is the sum of: - He : geodetic difference in level between the set and the furthest delivery point. - Hc : flow resistance along all the pipes and through other system components, such as valves, filters, etc.. - Hr : pressure required at the most unfavourable point. H tot = He+Hc+Hr Intake with positive head In this case, the necessary delivery head (H tot) will be reduced by the inlet pressure value (Hi). H tot = He+Hc+Hr- Hi Intake with negative head When the pumps suck from an underground tank or well, the necessary head will be increased by the value of the intake height (Ha):. H tot = He+Hc+Hr+ Ha In this case the intake height must be considered very carefully, bearing in mind that an excessive difference in level between the water storage tank and the set, or the wrong sizing of the intake pipe, can have adverse effects on pump operation, such as cavitation and unpriming. TECHNICAL APPENDIX 127
NPSH TECHNICAL APPENDIX The minimum operating values that can be reached at the pump suction end are limited by the onset of cavitation. Cavitation is the formation of vapour-filled cavities within liquids where the pressure is locally reduced to a critical value, or where the local pressure is equal to, or just below the vapour pressure of the liquid. The vapour-filled cavities flow with the current and when they reach a higher pressure area the vapour contained in the cavities condenses. The cavities collide, generating pressure waves that are transmitted to the walls. These, being subjected to stress cycles, gradually become deformed and yield due to fatigue. This phenomenon, characterized by a metallic noise produced by the hammering on the pipe walls, is called incipient cavitation. The damage caused by cavitation may be magnified by electrochemical corrosion and a local rise in temperature due to the plastic deformation of the walls. The materials that offer the highest resistance to heat and corrosion are alloy steels, especially austenitic steel. The conditions that trigger cavitation may be assessed by calculating the total net suction head, referred to in technical literature with the acronym NPSH (Net Positive Suction Head). The NPSH represents the total energy (expressed in m.) of the liquid measured at suction under conditions of incipient cavitation, excluding the vapour pressure (expressed in m.) that the liquid has at the pump inlet. To find the static height hz at which to install the machine under safe conditions, the following formula must be verified: hp + hz (NPSHr +.) + hf + hpv where: hp is the absolute pressure applied to the free liquid surface in the suction tank, expressed in m. of liquid; hp is the quotient between the barometric pressure and the specific weight of the liquid. hz is the suction lift between the pump axis and the free liquid surface in the suction tank, expressed in m.; hz is negative when the liquid level is lower than the pump axis. hf is the flow resistance in the suction line and its accessories, such as: fittings, foot valve, gate valve, elbows, etc. hpv is the vapour pressure of the liquid at the operating temperature, expressed in m. of liquid. hpv is the quotient between the Pv vapour pressure and the liquid s specific weight., is the safety factor. 1 The maximum possible suction head for installation depends on the value of the atmospheric pressure (i.e. the elevation above sea level at which the pump is installed) and the temperature of the liquid. To help the user, with reference to water temperature (4 C) and to the elevation above sea level, the following tables show the drop in hydraulic pressure head in relation to the elevation above sea level, and the suction loss in relation to temperature. Water temperature ( C) 2 4 6 8 9 11 12 Suction loss (m),2,7 2,, 7,4 1,4 21, Elevation above sea level (m) 1 1 2 2 3 Suction loss (m), 1,1 1,6 2,2 2,7 3,3 Friction loss is shown in the tables at pages 131-132 of this catalogue. To reduce it to a minimum, especially in cases of high suction head (over 4- m.) or within the operating limits with high flow rates, we recommend using a suction line having a larger diameter than that of the pump s suction port. It is always a good idea to position the pump as close as possible to the liquid to be pumped. Make the following calculation: Liquid: water at ~1 C γ = 1 kg/dm 3 Flow rate required: 3 m 3 /h Head for required delivery: 43 m. Suction lift: 3, m. The selection is an FHE 4-2/7 pump whose NPSH required value is, at 3 m 3 /h, di 2, m. For water at 1 C hp = Pa / γ = 1,33m, hpv = Pv / γ =,174m (,171 bar) The Hf flow resistance in the suction line with foot valves is ~ 1,2 m. By substituting the parameters in formula 1 with the numeric values above, we have: 1,33 + (-3,) (2, +,) + 1,2 +,17 from which we have: 6,8 > 4,4 The relation is therefore verified. 128

CHOOSING AND SIZING THE SURGE TANK The purpose of the surge tank is to limit the number of hourly starts of the pumps, placing part of its stock of water, which is maintained under pressure by the air above it, at the disposal of the system. The surge tank can be of the air cushion or diaphragm type. In the air cushion version there is no clear separation between air and water. Since part of the air tends to mix with water, it is necessary to restore it by means of air supply units or a compressor. In the diaphragm version, neither air supply units nor compressor are needed, as contact between air and water is prevented by a flexible diaphragm inside the tank. The following method, which is used to determine the volume of a surge tank, is valid both for horizontal and vertical surge tanks. When calculating the volume of the surge tank, it is generally sufficient to consider the first pump only. AIR-CUSHION SURGE TANK DIAPHRAGM TANK If you decide to use a diaphragm tank, the volume will be lower than that of the air-cushion tank.

For steel pipework, multiply the values by 1.41. For stainless steel, copper and coated cast iron pipework, multiply the values by 1.8. When the equivalent pipeline length has been determined, the flow resistance is obtained from the table of flow resistance. The values given are guideline values which are bound to vary slightly according to the model, especially for gate valves and non-return valves, for which it is a good idea to check the values supplied by the manufacturers.

PERFORMANCE WITH VARYING SPEED EQUIVALENCE RELATIONS Fitting the electric pump with a frequency converter makes it possible to vary the pump rotation speed, normally according to the system pressure parameter. Variations in electric pump speed result in modified performances according to the equivalence relations. Flow rate Head Power n1 = initial speed; Q1 = initial flow rate; H1 = initial head; P1 = initial power; n2= speed required. Q2= flow rate required. H2= head required. P2= power required Frequency ratios can be used instead of speed in practical applications, keeping 3 Hz as the bottom limit. Example : 2-pole Hz electric pump n1 =29 (point A) Flow rate (A) = 1 l/min; Head (A) = m By reducing the frequency to 3 Hz the speed is reduced to approx. n2 = 174 rpm (point B) Flow rate (B) = 6 l/min; Head (B) = 18 m The power of the new work point B is cut to about 22% of the initial power. SIZING THE DIAPHRAGM TANK IN SYSTEMS WITH SPEED VARIATION Variable speed booster sets need smaller tanks compared to traditional systems. Generally speaking, a tank with a litre capacity of just 1% of the nominal capacity of a single pump, expressed in litres per minute, is needed. The gradual starting of the pumps controlled by the frequency converters reduces the need to limit the number of hourly starts; the main purpose of the tank is to compensate for small system losses, stabilize the pressure and make up for pressure variations caused by sudden demand. Make the following calculation: Set made up of three electric pumps, each with a maximum flow rate of 4 l/min, for a total capacity of 12 l/min. The volume required for the tank is 4 litres. This size can be obtained by using two 24-litre tanks mounted directly onto the set s manifold. The calculation establishes the minimum value needed for proper operation. TECHNICAL APPENDIX 133 TECHNICAL APPENDIX
ASSESSMENT OF PROBABLE DEMAND (VALID IN U.K. ONLY) The method adopted is based on loading unit values as detailed in the Plumbing Engineering Design Guide published by the Institute of Plumbing. When designing a hot or cold water supply system an assessment must be made to obtain the maximum probable simultaneous demand. Depending on the type of services being provided it rarely occurs for all the appliances to be used at the same time therefore the design usually allows for a peak usage which is less than the maximum. Probable demand will depend on the type of building and its use, type of appliances installed and frequency of use. The simultaneous demand in most installations can be calculated with an adequate degree of accuracy using the loading unit concept. The usage patterns and types of appliances in different installations will vary greatly. Sports and Leisure centres for example are usually calculated directly by the flow rates of each appliance, without diversity factors. Each case will need to be looked at in its own right and assessed accordingly. Judgement of the designer must prevail. Loading unit values vary for each type of appliance. A loading unit has no precise value in terms of litres per second. See loading unit table below. By multiplying the total number of each appliance by the appropriate loading unit number and adding the resultant totals together, the recommended flow can be read from the chart. Loading unit table APPLIANCE Loading Recommended Unit Flow L/s LOADING UNITS 8 3 2 FLOW L/s 3 2 1 1 WC 1,,12 Wash basin (hot & cold) 3,3 Sink (hot & cold) 6,4 Bath (hot & cold) 2,6 Shower (hot & cold) 1,24 Washing machine 2,3 g_at_a_lu 1 1 8 4 8 6 4 3 2 Working Example 2 1.

ASSESSING HEAD REQUIREMENT (VALID IN U.K. ONLY) The head required in a boosted cold water system consists of three components, static head, residual pressure and system friction losses. The values of these three components are added together to give the total required head at the system flow rate. Static head (He): This is the difference between the break tank low water line and the highest discharge point in the building. If the height of the build is not known, then 2.8-3. metres per floor can be used to assess the building height. Residual pressure (Hr): This is the pressure required at the highest outlet device, normally 2metres. Note: some modern showers may require higher pressures. System friction losses (Hc): The total losses through pipework, pipework fittings, valves, PRVs and all other equipment fed through the pumpset must be added to find the total system losses. On conventional systems that do not include excessive runs of pipe or specialised components a rough guide would be to allow. metres friction loss for each metre of static head. G_at a Hc Hr He H Example: Static head (He): Building height four floors @ 2.8m each = 11.2m + Residual pressure (Hr): Pressure at highest outlet = 2m + Friction loses (Hc): 11.2 (static head) x. =.6m Total pump head required (H) = 31.76m (3.11 Bar) Pressure limitations The designer must ensure that adequate precautions are taken to ensure that the system is capable of withstanding the closed valve head produced by the pump set. In cases where closed valve pressures cannot be tolerated, pressure reducing valves should be fitted down stream of the booster set. PIPE SIZE SUCTION PIPE DELIVERY PIPE Velocity Pipework within the system should be sized to limit the velocity to the figures stated in table below. Higher velocities will lead to excessive noise, wear and higher running costs. m/s m/s Less than 8mm,46,91 to 1,7 1-1mm, 1,22 to 1,2 2mm,76 1,68 2 and above,91 1,82 to 2,13 g_at_a_fs BOOSTER SIZING What information do we require to size a booster set? As a minimum we need to know: The total flow rate, or information to assess this. The total head at flow rate, or the height of building. If the pumps are to operate under positive head, or suction lift conditions. Where the set is to be sited, I.E. basement or roof. Preferred choice fixed of variable speed Additional information if available: How to split the duty for particular applications I.E. duty/standby or duty/assist.
