CR, CRI, CRN, 1 CRE, CRIE, CRNE 1. Product data Introduction This data booklet deals with Grundfos CR, CRI and CRN as well as CRE, CRIE and CRNE pumps. CRE, CRIE, CRNE Product data CR, CRI, CRN TM 7397 511 Fig. CRE, CRIE and CRNE pumps Fig. 1 CR, CRI and CRN pumps CR, CRI and CRN pumps are vertical, multistage centrifugal pumps. The in-line design of the pumps enables installation in a horizontal one-pipe system where the suction and discharge ports are in the same horizontal level and have the same pipe dimensions. This design provides a more compact pump design and pipework. Grundfos CR pumps are available in various sizes and various numbers of stages to provide the flow and pressure required. CR pumps are designed for a variety of applications ranging from the pumping of potable water to the pumping of chemicals. The pumps are therefore suitable for a wide diversity of pumping systems where the performance and material of the pump meet specific demands. The CR pumps consist of two main components: the motor and the pump unit. The CR pump motor is a Grundfos motor designed to EN standards. The pump unit consists of optimised hydraulics, various types of connections, a sleeve, a pump head and various other parts. CR pumps are available in various material versions according to the pumped liquid. GR 5381 CRE, CRIE and CRNE pumps are built on the basis of CR, CRI, CRN pumps. CRE, CRIE and CRNE pumps belong to the so-called E-pump family. CRE, CRIE and CRNE pumps are referred to as E-pumps. The difference between the CR and CRE pump ranges is the motor. CRE, CRIE and CRNE pumps are fitted with an E-motor, i.e. a motor with built-in frequency converter. The CRE pump motor is a Grundfos MGE motor designed to EN standards. The frequency converter enables continuously variable control of the motor speed, which makes it possible to set the pump to operation at any duty point. The purpose of continuously variable speed control of the motor speed is to adjust the performance to a given requirement. CRE, CRIE and CRNE pumps are available with an integrated pressure sensor connected to the frequency converter. The pump materials are identical to those of the CR, CRI and CRN pump range. Selecting a CRE pump Select a CRE pump if the following features are required: Controlled operation, i.e. consumption fluctuates. Constant pressure. Communication with the pump. Adaptation of performance through frequency-controlled speed control offers obvious benefits such as: energy savings increased comfort control and monitoring of the pump performance. info@lenntech.com - Tel.+31()15-1.9. www.lenntech.com - Fax.+31()15-1..89 3

CR, CRI, CRN, CRE, CRIE, CRNE Control of E-pumps. Control of E-pumps Examples of E-pump applications CRE, CRIE and CRNE pumps are the ideal choice for a number of applications characterised by a demand for variable flow at constant pressure. The pumps are suited for water supply systems and pressure-boosting as well as for industrial applications. Depending on the application, the pumps offer energy savings, increased comfort and improved processing. E-pumps in the service of industry The industry uses a large number of pumps in many different applications. Demands on pumps in terms of pump performance and mode of operation make speed control a must in many applications. Below is listed some of the applications in which E-pumps are often used. Constant pressure Water supply washing and cleaning systems distribution from waterworks humidifying systems water treatment systems process boosting systems, etc. Example: Within industrial water supply, E-pumps with integrated pressure sensor are used to ensure a constant pressure in the piping system. From the sensor, the E-pump receives inputs about changes of pressure as a result of changes in the consumption. The E-pump responds to the input by adjusting the speed until the pressure is equalised. The constant pressure is stabilised once more on the basis of a preset setpoint. Constant temperature Air-conditioning systems at industrial plants industrial cooling systems industrial freezing systems casting and moulding tools, etc. Example: In industrial freezing systems, E-pumps with temperature sensor increase comfort and lower operating costs compared with pumps without a temperature sensor. An E-pump continuously adapts its performance to the changing demands reflected in the differences in temperature of the liquid circulating in the freezing system. Thus, the lower the demand for cooling, the smaller the quantity of liquid circulated in the system and vice versa. Constant flow Steam boiler systems condensate systems sprinkler irrigation systems chemical industry, etc. Example: In a steam boiler, it is important to be able to monitor and control pump operation to maintain a constant level of water in the boiler. By using an E-pump with level sensor in the boiler, it is possible to maintain a constant water level. A constant water level ensures optimum and cost-efficient operation as a result of a stable steam production. Dosing applications Chemical industry, i.e. control of p values petrochemical industry paint industry degreasing systems bleaching systems, etc. Example: In the petrochemical industry, E-pumps with pressure sensor are used as dosing pumps. The E-pumps help to ensure that the correct mixture ratio is achieved when more liquids are combined. E-pumps functioning as dosing pumps improve processing and offer energy savings. E-pumps in commercial building services Commercial building services use E-pumps to maintain a constant pressure or a constant temperature based on a variable flow. Constant pressure Water supply in high-rise buildings such as office buildings and hotels. Example: E-pumps with pressure sensor are used for water supply in high-rise buildings to ensure a constant pressure even at the highest draw-off point. As the consumption pattern and thus the pressure changes during the day, the E-pump continuously adapts its performance until the pressure is equalised. Constant temperature Air-conditioning systems in hotels, schools, etc. building cooling systems, etc. Example: E-pumps are an excellent choice for buildings where a constant temperature is essential. E-pumps keep the temperature constant in air-conditioned, high-rise glass buildings, irrespective of the seasonal fluctuations of the outdoor temperature and various heat impacts inside the building. 1 info@lenntech.com - Tel.+31()15-1.9. www.lenntech.com - Fax.+31()15-1..89

CR, CRI, CRN, CRE, CRIE, CRNE Control options of E-pumps Communication with CRE, CRIE, CRNE pumps is possible by means of either of the following: a central management system remote control (Grundfos R1) a control panel. The purpose of controlling an E-pump is to monitor and control the pressure, temperature, flow and liquid level of the system. Remote control The Grundfos R1 remote control is available as an accessory. The operator communicates with the E-pump by pointing the R1 at the control panel of the E-pump terminal box. Control of E-pumps Central management system Communication with the E-pump is possible even if the operator is not present near the E-pump. Communication is enabled by connecting the E-pump to a central management system. This allows the operator to monitor the pump and to change control modes and setpoint settings. Fig. 8 R1 remote control With the R1 it is possible to monitor and change control modes and settings of the E-pump. TM 98 8 Control management system Control panel The control panel of the E-pump terminal box makes it possible to change the setpoint settings manually.

CR, CRI, CRN, CRE, CRIE, CRNE Control of E-pumps Control modes for E-pumps Grundfos offers CRE, CRIE and CRNE pumps in two different variants: CRE, CRIE and CRNE with integrated pressure sensor CRE, CRIE and CRNE without sensor. CRE, CRIE, CRNE with integrated pressure sensor Use CRE, CRIE and CRNE pumps with integrated pressure sensor in applications where you want to control the pressure after the pump, irrespective of the flow. For further information, see section Examples of E-pump applications, page 1. Signals of pressure changes in the piping system are transmitted continuously from the sensor to the pump. The pump responds to the signals by adjusting its performance up or down to compensate for the pressure difference between the actual and the desired pressure. As this adjustment is a continuous process, a constant pressure is maintained in the piping system. In constant-curve mode, the pump is not controlled. It can be set to pump according to a preset pump characteristic within the range from min. curve to max. curve. See fig. 1. Min. Fig. 1 Constant-curve mode Max. CRE, CRIE and CRNE without sensor CRE, CRIE and CRNE pumps without sensor are suitable in these situations where uncontrolled operation is required. where you want to fit another sensor later in order to control the flow, temperature, differential temperature, liquid level, p value, etc. at some arbitrary point in the system. CRE, CRIE and CRNE pumps without sensor can be set to either of these control modes: controlled operation uncontrolled operation (factory-setting). In controlled-operation mode, the pump adjusts its performance to the desired setpoint. See fig. 13. Q TM 933 1 Fig. 1 CRE, CRIE and CRNE pumps A CRE, CRIE or CRNE pump with integrated pressure sensor facilitates installation and commissioning. CRE, CRIE and CRNE pumps with integrated pressure sensor can be set to either of these control modes: constant pressure (factory setting) constant curve. In constant-pressure mode, the pump maintains a preset pressure after the pump, irrespective of the flow. See fig. 11. set Q Fig. 11 Constant-pressure mode TM 7398 33 TM 93 79 Min.

CR, CRI, CRN, 5 CRE, CRIE, CRNE Normally, E-pumps are used in applications characterised by a variable flow. Consequently, it is not possible to select a pump that is constantly operating at optimum efficiency. In order to achieve optimum operating economy, the pump should be selected on the basis of the following criteria: The max. duty point required should be as close as possible to the Q curve of the pump. The flow rate at the duty point required should be close to the optimum efficiency (eta) for most operating hours. Between the min. and max. performance curves, E-pumps have an infinite number of performance curves, each representing a specific speed. Therefore, it may not be possible to select a duty point close to the 1 % curve. Min. curve Max. curve Fig. Min. and max. performance curves In situations where it is not possible to select a duty point close to the 1 % curve, the below affinity equations can be used. The head (), the flow (Q) and the input power (P) are all the appropriate variables for the motor speed (n). Note The approximated formulas apply on condition that the system characteristic remains unchanged for n n and n x and that it is based on the formula = k x Q where k is a constant. The power equation implies that the pump efficiency is unchanged at the two speeds. In practice, this is not quite correct. To obtain a precise calculation of the power savings resulting from a reduction of pump speed, take into account the efficiencies of the frequency converter and the motor.

8 CR, CRI, CRN, CRE, CRIE, CRNE Pumped liquids 8. Pumped liquids Thin, non-explosive liquids, not containing solid particles or fibres. The liquid must not chemically attack the pump materials. When pumping liquids with a density and/or viscosity higher than that of water, use oversized motors, if required. Whether a pump is suitable for a particular liquid depends on a number of factors of which the most important are the chloride content, p value, temperature and content of chemicals, oils, etc. Please note that aggressive liquids, such as sea water and some acids, may attack or dissolve the protective oxide film of the stainless steel and thus cause corrosion. The CR(E), CRI(E), CRN(E) pumps are suitable for the following liquids: CR(E), CRI(E) CR(E), CRI(E) pumps are suitable for non-corrosive liquids. Use CR(E), CRI(E) pumps for liquid transfer, circulation and pressure boosting of cold or hot clean water. CRN(E) CRN(E) pumps are suitable for industrial liquids. Use CRN(E) pumps in systems where all parts in contact with the liquid must be made of high-grade stainless steel. CRT(E) For saline or chloride-containing liquids such as sea water or for oxidising agents such as hypochlorites, Grundfos offers CRT(E) pumps made of titanium. See the separate data booklet on CRT(E) available on www.grundfos.com (WebCAPS). List of pumped liquids A number of typical liquids are listed below. Other pump versions may be applicable, but those stated in the list are considered to be the best choices. The table is intended as a general guide only and cannot replace actual testing of the pumped liquids and pump materials under specific working conditions. owever, use the list with some caution. Factors such as those mentioned below may affect the chemical resistance of a specific pump version: concentration of the pumped liquid liquid temperature pressure. Take safety precautions when pumping dangerous liquids. Notes D E F Often with additives. The density and/or viscosity differ from that/those of water. Take this factor into account when calculating motor output and pump performance. Pump selection depends on many factors. Contact Grundfos. Risk of crystallisation/precipitation in shaft seal. 1 ighly inflammable liquid. Combustible liquid. 3 Insoluble in water. Low self-ignition point.

CR, CRI, CRN, 1 CRE, CRIE, CRNE 1. Variants Lists of variants The variants are available on request. Although the Grundfos CR(E), CRI(E), CRN(E) product range offers a number of pumps for different applications, customers require specific pump solutions to satisfy their demands. See the following documents: Grundfos CR "Custom-built pumps" catalogue Grundfos "CR, CRN high pressure" data booklet. Below please find the range of options available for customising the CR(E) pumps to meet the customers demands. Contact Grundfos for further information or for requests other than the ones mentioned below. Motors Variant ATEX-approved motor Motor with anti-condensation heating unit Motor with thermal protection Oversize motor -pole motor Shaft seals Variant Shaft seal with FFKM O-ring Seal with flush, quench seal Air-cooled shaft seal system Double seal with pressure chamber Description For operation in hazardous atmospheres, explosion-proof or dust-ignition-proof motors may be required. For operation in humid environments motors with built-in anti-condensation heating unit may be required. Grundfos offers motors with built-in bimetallic thermal switches or temperature-controlled PTC sensors (thermistors) incorporated in the motor windings. Ambient temperatures above C or installation at altitudes of more than 1 metres above sea level require the use of an oversize motor (i.e. derating). Grundfos offers -pole standard motors. Description Shaft seals with FFKM or FXM O-ring are recommended for applications where the pumped liquid may damage the standard O-ring material. Recommended for applications involving crystallising, hardening or sticky liquids. Recommended for applications involving extremely high temperatures. No conventional mechanical shaft seal can withstand liquid temperatures of up to 18 C for any length of time. For such applications, Grundfos unique air-cooled shaft seal system is recommended. In order to ensure a low liquid temperature around the standard shaft seal, the pump is fitted with a special air-cooled shaft seal chamber. No separate cooling is required. Recommended for applications involving poisonous or explosive liquids. Protects the surrounding environment and the people working in the vicinity of the pump. Consists of two seals mounted in a "back-to-back" arrangement inside a separate pressure seal chamber. As the pressure in the chamber is higher than the pump pressure, leakage is prevented. A dosing pump or a special pressure intensifier generates the seal chamber pressure. Variant CR MAGdrive Pumps Variant orizontally mounted pump Low-temperature pump igh-speed pump up to 7 bar igh-pressure pump up to 7 bar Low-NPS pump (improved suction) Pump with bearing flange Belt-driven pump Pump for pharmaceutical and biotechnological applications Connections and other variants Variant Pipe connections TriClamp connection Electropolished pump Description Magnetically driven pumps for industrial applications. Key applications are industrial processes involving the handling of aggressive, environmental, dangerous or volatile liquids, e.g. organic compounds, solvents, etc. Description For safety or height reasons, certain applications, for instance on ships, require the pump to be mounted in the horizontal position. For easy installation the pump is fitted with brackets that support motor and pump. Exposed to temperatures down to - C, coolant pumps may require neck rings with a different diameter in order to prevent impeller drag. For high-pressure applications, Grundfos offers a unique pump capable of generating a pressure of up to 7 bar. The pump is fitted with a high-speed motor, type MGE. The direction of rotation is the opposite of that of standard pumps, and the chamber stack is turned upside-down, as a result of which the pumped liquid flows in the opposite direction. For high-pressure applications, Grundfos offers a unique double pump system capable of generating a pressure of up to 7 bar. Recommended for boiler-feed applications where cavitation may occur due to poor inlet conditions. The bearing flange is suitable for applications where the inlet pressure is higher than the maximum pressure recommended. The bearing flange increases the life of motor bearings. Recommended for standard motors. Belt-driven pumps designed to operate in places with limited space or where no electrical power is available. CRN(E) pumps designed for applications requiring the sterilisation and CIP capability of pipes, valves and pumps. (CIP = Cleaning-In-Place.) Description In addition to the wide range of standard flange connections, a 1 bar DIN standard clamping flange is available. Customized flanges are available according to specifications. TriClamp connections are of a hygienic design with a sanitary coupling for use in the pharmaceutical and food industry. To substantially reduce the risk of corrosion of the materials. For use in the pharmaceutical and food industry. Variants info@lenntech.com - Tel.+31()15-1.9. www.lenntech.com - Fax.+31()15-1..89 91
