VARIABLE VOLUME PISTON PUMP


Pressure Compensating

When the pressure reaches the value set with the compensator, the flow is reduced automatically and the set pressure is maintained.
The pressure and flow are controlled manually.

Remote Pressure Control

The pressure can be controlled according to the pilot pressure.
The flow can be controlled manually.


Two Pressure-Two Flow Control

By means of the sequence valve, two stage flow rate can be obtained and each flow rate has the different pressure eventually enabling energy savings.

Solenoid Cut-Off Control

An unloading solenoid valve is used to minimize the lost energy when the pump output is not required.

Heat generated is very small.

Two Pressure Cut-Off Control

By means of "ON" "OFF" control of solenoid valves, two different pressure cmpensating types can be obtained.

Load Sensing Control

The "HL" compensator is used for load sensing circuits and is a true load sensor. This is the "B" compensator with a pin in the compensator spool. The pin prevents pilot flow from entering the circuit which will eliminate creeping of the load.

The "HL" compensator will let the pump deliver a constant flow rate to the circuit by providing an adjustable △ P across the customers orifice or valve. The pump will operate at 17.2~27.5 bar (250-400 psi) above"Load pressure".
