PV series Variable Displacment Piston PumpCOMPENSATORS INSTRUCTIONS: A: Standard pressure compensator:
The basic function of variable displacement pump is maintains the constant working pressure of pumpand adjusting the flow automatically to meet the demand of system. When the Outlet pressure P is lowerthen the setting pressure, the compensator starts working, port A connects to pump case and reset the spring to keep the pump at full flow. When the pump pressure reaches the setting pressure, the compensatorport P1 connects to A, it force the spool of compensator to push swash plate decrease angle and reduce the flow of pump and to meet the system pressure.
The main difference between Standard and Remote control type compensator is that GT type remote compensator can be controlled by a pilot relief valve trough the Port Pp . The pilot flow is about 1-1.5 l/min and supply by internal flow of pump . The pilot valve can be installed in some area wherecan have easier control of system, such as the panel of machine. Besides GT compensator is more precision and is higher reaction then standard compensator. The pilot pressure valve also can be controlled electrically by proportional pressure control valve or solenoid directional control valve for lowpressure Stand-by operation.
GM: Remote controlled pressure compensator - Modular type, valves not included
GM type remote pressure compensator has same function as GT type controller, the difference is that GMtype provides a standard mounting interface which meets the standard of NG6, DIN24340, Cetop 3, and D03. This interface allows direct mounting of pilot valve, manually or electrically controlled are available.It also allows completed multiple pressure circuit mount on the compensator directly. We have preparevariety of these components , please contact with our dealer or send us inquiry when necessary.
Remark: All remote pressure compensator have factory pressure difference setting of 15 bar.At this setting, the outlet pressure pump is also nearly 15 bar and higher then the setting pressure of pilot control valve.
ELECTRIC CONTROLLED UNLOADING TYPE:Combine with a directional control valve(2 or 3 positions) and pilot valve, this compensator couldcontrol the actuator works in constant speed , two work pressure setting and with unloading functionaccording to system design. It saves energy and reduces the noise when system at long time waiting or at no-load condition.
GR: Electric controlled Unloading type
GB: Dual pressure controlled type
GC: Dual pressure + electric controlled unloading type

LOAD-SENSING TYPE:
HL: Load-sensing compensator - Threading connectionFor load-sensing compensator, the pilot flow comes from external main pipe. Please refer to following drawing.The compensator is connects to the port of main flow after the throttle valve. Standard factory setting of the pressure difference of compensator is 10 bars. The pressure difference is the control signal of compensator, Load-sensing compensator controls the main output flow of pump, and it also keeps the pressure drop of main flowresistor constantly steady. When rotation speed of pump is changing or the load of actuator changing, theworking speed will not be influenced under compensator controls. It can have pressure control function simplyby adding an Orifice(0.8mm) and a pressure pilot valve. See the circuit diagram below.
HM: Load-sensing compensator - Modular typeHM load-sensing compensator has a NG6 mounting interface, it allows direct mounting of modular type pilot relieve valve for pressure compensation. Due to the interaction pressure and flow compensation, the characteristiccurve is not an ideal curve. The pressure drop causes by the performance of pilot valve.Remark: An Orifice for pilot valve will be attached in the package for free.
HJ: Twin Load-sensing compensator - Modular type
HA: Twin Load-sensing compensator - Modular type - Relief valve included
Twin Load-sensing compensator was designed for the system which need higher accurate control of pressure compensation. For avoiding the interaction of pressure and flow compensation, HJ type combines two compensators, one controls pressure compensation and another controls flow compensation. It also has NG6 mounting interface and allows direct mounting of modular type pilot relieve valve or proportional relief valve. The performance of HJ (HA) controller has higher efficiency then HM type, please see the characteristic curve.
When adding a proportional flow control valve in the out port, then it can achieves the circuit for proportional flow & pressure control. This is a typical energy saving system.

CONSTANT POWER CONTROL TYPE:
Constant Power compensator it controls the pump input power accordance with motor output. When the discharge pressure rises, the output flow decreases corresponding to preset input power. With the constantpower compensator, the pump can acts for function of 2 pumps; one is low pressure and large flow and another is high pressure and small flow. Thus the horse power of motor can be reduced and reaches the goal of power-saving.

The maximum torque of the individual shaft must not be exceeded. For double pump combination, there will be no problem because the PV series provide 100% thru drive torque. But it is possible to be reachedor exceeded by triple or more pumps combination. Therefore it is necessary to calculate the torque factor and compare it with the allowable torque limit factor. >Sufficiency: Total value of individual pump torque factors < Torque limit factor of the main pump.
1.
For make the calculations become easier and more friendly, we have listed the Torque Limit factors in above table for different shafts of pumps. These factor have included material factor, safety factor and conversion factors. User do not have to calculate actual torques in Nm. It need only simply calculate the torque factor for each pump and have the sum of them, and compare the sum with the values in the table.

1. Fluid recommendationsPremium quality hydraulic mineral oil fluids are recommended,like H-LP oils to DIN 51524, part 2. The viscosityrange should be 25 to 50 mm2/s(cst) at 50 °C. Operating temperatures -10 to +70 °C. For other fluids such as phosphoric acid esters or for, other operating conditions, consult us for assistance.2.SealsNBR ( Nitrile ) seals are used for operation with hydraulic fluids baseed on mineral oil. For synthetic, as perhapsphosphoric acid esters, Fluorocarbon seals are required. Consult us for ssistance.3.FiltrationFor maximum pump and system component functionability and life, the system should be protected fromcontamination by effective filtration, Fluid cleanness should be in accordance with ISO classification ISO 4406.The quality of filter elements should be in accordance with ISO standards.(1)Minimun requirement for filtration rate x ( mm ): General hydraulic systems for satisfactory operation: Class 19/15, to ISO 4406 X=25µ m( ß 10 ≥ 75) to ISO4572(2)Hydraulic systems with maxmized component life and functionability: Class 16/13, to ISO 4406 X=10µ m( ß 10 ≥ 75) to ISO4572It is recommended to use return line or pressure filters. The use of suction filters should be avoided, especiallywith fast response pumps. Bypass filtration is a good choice for best filter efficiency.4. Installation and mountingHorizontal mounting: Outlet port side or top. Inlet port side or bottom, drain port always uppermost.Vertical mounting : Shaft pointing upwards.Install pump and suction line in such a way that the maximum inlet vacuum never exceeds 0.8 bar absolute.The inlet line should be as short and as straight as possible. A short suction line cut to 45˚ is recommendedwhen the pump is mounted inside the reservoir, to improve the inlet conditions. All connections to be leadfree,as air in the suction line will cause cavitations, noise , and damage to the pump.5. Shaft rotation ad alignmentPump and motor shafts must be aligned within 0.25mm T.I.R. maximum. A floating coupling must be used.Bellhousings and couplings can be ordered from us. Please follow the coupling manufacturer’s installation instructions. Consult us for assistance on radial load type drives.6.Start upPrior to start up, the pump case must be filled with hydraulic fluid ( use case drain port ). Initial start up shouldbe at zero pressure with an open circuit to enable the pump to prime. Pressure should only be increased oncethe pump has been fully primed.Attention: Check motor rotation direction. Operating noise of pumps The normal operating noise of a pump and consequently the operating noise of the entire hydraulic system is largely determined by where and how the pump is mounted and how it is connected to the down stream hydraulicsystem. Also size, style and installation of the hydraulic tubing have major influence on the overall noise emittedby a hydraulic system.Noise reductin measuresFlexible elements help to prevent pump body vibration being transmitted to other construction elements, wherepossible amplification may occur. Such elements can be:Bell housing with elastic dampening flange with vulcanized labyrinth(1)Floating and flexible coupling(2)Damping rails(3)Orsilent blocks for mounting the electric motor or the foot mounting flange(4)Flexible tube connections ( compensators ) or hoses on inlet, outlet and drain port of the pump.(5)Exclusive use of gas tight tube fittings for inlet connections to avoid ingression of air causing cavitations and excessive noise.7.Drain line The drain line must lead directly to the reservoir without restriction. The drain line must not be connected to any other return line. The end of the drain line must be below the lowest fluid lvel in the reservoir and as faraway as possible from the pump inlet line. this ensures that the pump does not empty itself when not in operationand that hot aireated oil will not be recirculated. For the same reason, when the pump is mounted inside the reservoir, the drain line should be arranged in such a way that a siphon is created. This ensures that the according to the port size and a straight low pressure fitting with maximized bore should be used.
