AXIAL PISTON PUMP - J9V045 The J9V 045 model piston pump is offered with a variety of control options that are designed for optimum performance of the pump in different CONSTANT PRESSURE CONTROL ( CP) This control maintains the pressure in a hydraulic circuit at a constant set value within the control range during pump operation irrespective of changing flow demands of the load on the pump. The pump supplies only that much volume of oil as required by the load. If the pressure in the circuit tends to raise above the set value, then the pump swash plate angle is proportionally reduced which...

AXIAL PISTON PUMP - J9V045 PRESSURE, FLOW& POWER CONTROL (CPFH) This control allows to limit the pump drive power at a constant speed (rpm) to set value in relation to the pump flow and pressure (p X V = constant). Efficient power consumption is achieved with this and a constant drive torque is maintained with varying Operating pressure exerts a force on a piston within the control piston on to the swash plate. An externally adjustable spring force acts on the opposite side of this and this determines the power setting. When the force exerted by the operating pressure is more, the pilot...
