General Information Pumps and Motors GPA and GP1 Pumps Light/medium duty pumps Parker s truck gear pumps are ideal for operators of light trucks for their hydraulic power needs. The GPA/GP1 series gear pumps are available to suit most applications. They are light and compact, and can be installed in either rear or or side mount configuration thanks to their unique dual port layout. The smaller GPA series is built with an extruded aluminum houising for minimum weight. The larger GP1 pumps are built with compact cast iron housings for strength. The gear pumps complement our heavy duty piston pumps and vane pumps. The performance and characteristics are ideal for many light and/or intermittent applications, including the famous Parker reliability, and they are engineered with a long, trouble-free service life. Features Compact and light weight - easy to install even on small vehicles Series GPA Quiet operation - low noise emissions are important in sensitive areas Robust and reliable - means a long, trouble-free service life Built for high rpm s - less sensitive to over-speeding Series GP1 Bi-directional - easy to install Side or rear mount - use the ports on the side or at the rear, whichever is most suitable for the application. See page 15 4 Parker Hannifin
General Information Pumps and Motors F1 Pump ISO Series F1 is a further development of our well known 'truck pump', the F1. The F1 offers many additional values for operators of cargo cranes, hook loaders, skip loaders, forest cranes, concrete mixers and similar truck applications. Series F1 is a very efficient and straight forward pump design with unsurpassed reliability. Its small envelope size gives a simple and inexpensive installation. 1 Features of the F1 are: High selfpriming speeds Operating pressures up to 400 bar High overall efficiency Low noise level Small installation dimensions Low weight... thanks to: - 45 bent-axis angle - Optimal inlet port geometry in the end cap - Single housing design - Spherical pistons - high speeds - Laminated piston rings - low leakage - Positive synchronisation with timing gear - Installation above the reservoir level possible - Tolerates low temperatures and high temperature shocks - Shaft end and mounting flange meet the ISO standard for all sizes F1 piston with laminated piston ring.

General Information Pumps and Motors F2 Twin-flow pump 1 Series F2 is a further development of the twin-flow version of series F1, the very first bent-axis truck pump on the market to feature two entirely independent flows. With a suitable build-up of the hydraulic system, the main advantage with a twin-flow pump is that three different flows can be provided at the same engine speed. The twin-flow pump makes it possible to further optimise the hydraulic system and offers: Less energy consumption Reduced risk of system overheating Lower weight Easier installation Standardised system solutions The twin-flow pump makes it possible to operate two work functions that are independent of each other which leads to higher speed and an increased operating precision. Another requirement can be a large and a small flow, or two equal flows. All of these alternatives are possible with the twin-flow pump. The pump can be utilised to provide one flow at high system pressure, and, as soon as the pressure has decreased sufficiently, add the flow from the other circuit. This eliminates the risk of exceeding the PTO power rating and, at the same time, provide an optimal driving function. Typical twin-flow applications Large truck loaders Forestry cranes Hook loaders/lift dumpers Tipper/crane combinations Refuse collecting vehicles The pump shaft end/mounting flange meets the ISO standard and suits PTO direct mounting. See page 34 7 Parker Hannifin
General Information Pumps and Motors T1 Pump The T1 fixed displacement pump is a further development of series T1, which was specifically designed to meet the requirements of light duty truck applications with short, non-frequent operating cycles such as tippers, and small loaders. The design is very similar to that of the F1 series pumps but is even more compact. It utilises our well proven 45 concepts with spherical pistons and laminated piston rings, offering high volumetric and mechanical efficiencies and, thanks also to the small number of parts, unprecedented reliability. Shaft speed to 2300 rpm Operating pressure up to 350 bar High overall efficiency Low weight Small installation dimensions Robust construction Typical T1 applications Front end tippers Under body tippers Hydraulic system infrequently used and with short cycle times. The T1, with shaft and mounting flange configuration conforming to the European standard, can be installed on most European truck gearboxes. Suitable powertake-offs are also available from Parker Hannifin. See page 37 8 Parker Hannifin
General Information VP1 Pump The VP1 is a variable displacement pump for truck applications. It can be close-coupled to a gearbox PTO (power take-off) or to a coupling independent PTO (e.g. an engine PTO) which meets ISO standard 7653-1985. An application that makes full use of all the features of the VP1 is truck cranes with a load sensing system. The complex systems of refuse collection vehicles and sewage trucks as well as various combinations of tippers, cranes, snow ploughs, and salt/sand spreaders can also be greatly simplified and optimised with the VP1 pump. The VP1 provides the hydraulic system with the correct amount of fluid at precisely the right moment, effectively reducing energy consumption and heat generation. This means a smoother and quieter hydraulic system with much reduced impact on the environment. The VP1 is highly efficient and extremely light. It is reliable, economical and easy to install. The four frame sizes, VP1-045, -075, -095 and -120 have small installation dimensions. Pumps and Motors The VP1 is suitable for all load sensing systems, regardless of make. 1 Design Large angle - compact design The pump design permits a large angle, 20, between piston and slipper shoe/swashplate, providing compactness and small outer dimensions. Tandem coupling The through-shaft on VP1-45/-75 permits tandem coupling of an additional pump, such as a series F1 fixed displacement pump. Long life The VP1 is designed for trucks with hydraulic load sensing systems. It is sturdy, yet simple, with few moving parts. The result is a reliable pump with long service life. Features Variable displacement Low noise level High power-to-weight ratio Compact and light Highly efficient Sturdy design Withstands low temperatures Can be close coupled and tandem mounted. (tandem coupling only for VP1-45/-75) Retainer plate The retainer plate (refer to the cut-away illustration in chapter 8) is of a heavy duty design which makes the pump withstand high shaft speeds and fast speed changes.(e. g. engine PTO).

Pump and Line selection GPA, GP1, F1, F2, T1 and VP1 A suitable pump size for a truck application can be selected as follows: Operating conditions As an example, a cargo crane specifies: Flow: 60-80 l/min Pressure: 230 bar Diesel engine speed 800 rpm Determine pump speed As example a PTO with a Gear Ratio of 1:1.54. The pump speed will be: 800 x 1.54 1200 rpm Select a suitable pump size Use diagram 1 and select a pump that will provide 60-80 l/min at 1200 rpm. Follow line 'a' (1200 rpm) until it crosses line 'b' (70 l/min). F1-61 is a suitable choice Required input torque Make sure the PTO and the gear-box tolerates the pump torque. Use diagram 2 to obtain the required pump torque. Follow a line from 'c' (230 bar) until it crosses the F1-61 line (the selected pump). Read 220 Nm (at 'd') NOTE: A rule-of-thumb is to select the highest PTO ratio and the smallest pump size that meets the crane specification without exceeding the pump speed, pressure, and power limitations.

Pump and Line selection In order to obtain sufficient inlet (suction) pressure to the pump, low noise level and low heat generation, flow speeds shown in table 2, right, should not be exceeded. From table 1 (page 13), select the smallest line dimension that meets the flow speed recommendation; example: At 100 l/min, a 50 mm suction line and a 25 mm pressure line is needed. GPA, GP1, F1, F2, T1 and VP1 NOTE: Long inlet (suction) lines, low inlet pressure (caused by e.g. a reservoir positioned below the pump) and/or low temperatures may require larger line dimensions. Alternatively, the pump speed will have to be lowered to avoid pump cavitation (which may cause noise, deteriorating performance and pump damage).

NOTE: The bending moment caused by the weight of a tandem assembly normally exceeds that allowed by the PTO. To prevent damage, the auxiliary pump should be supported by a bracket attached to the gearbox; it must not be fastened to the truck chassis. Likewise, when the tandem assembly is installed on a separate bracket and driven by a cardan shaft, the auxiliary pump should have a support attached to the pump bracket. Fig. 3. Adaptor kit (P/N 379 7795) for tandem coupling. IMPORTANT Contact Parker Hannifin for additional information when considering tandem mounting a second VP1 pump. 44 Parker Hannifin

This means that energy consumption and heat generation are minimised and much reduced in comparison with a fixed displacement pump used in the same system. Diagram 1 shows the required power (flow times pressure) in a constant flow system with a fixed displacement pump. p Max Pressure Corner power Diagram 2 shows the sharply reduced power requirement in a load sensing system with a variable displacement pump such as the VP1. In both cases the pump pressure is slightly higher than what is required by the heaviest load ( Load 2 ) but the VP1, because of the much smaller flow being delivered, needs only the power indicated by the shaded area Load power. In a constant flow system, on the other hand, excess fluid is shunted to tank and the corresponding power, Wasted power (shown in diagram 1), is a heat loss. p Max Pressure Corner power 8 Wasted power Wasted power p Load Load 1 Load 2 Load power Load 3 p Load Load 1 Load 2 Load power Load 3 Q Load 1-3 Q Max Flow Diagram 1.

System Information LS load sensing control function Refer to corresponding hydraulic schematic below. A selected 'opening' of the directional control valve spool corresponds to a certain flow to the work function. This flow, in turn, creates a pressure differential over the spool and, consequently, also a p between the pump outlet and the LS port. When the differential pressure decreases (e.g. the directional valve is opened further) the p also decreases and the LS valve spool moves to the left. The pressure to the setting pistons then decreases and the pump displacement increases. The increase in pump displacement stops when the p finally reaches the setting (e.g. 25 bar) and the forces acting on the valve spool are equal. If there is no LS signal pressure (e.g. when the directional valve is in the neutral, no-flow position) the pump only delivers sufficient flow to maintain the standby pressure as determined by the p setting.
