General performance specifications 1 Standard SAE C non-through drive. 2 The 620 is capable of running at higher pressures than shown. In order to not void the warranty, you must provide duty cycle information and receive written approval. 3 Less than 10% of duty cycle. 4 Momentary system pressure spikes only. 5 Ratings based on Flange ports. Rated speed at 1 bar absolute [0 in Hg vac] inlet pressure and 100% displacement. For Max Speed see inlet pressure vs. speed charts. 6 Bearing life ratings at rated speed - 1 bar abs (0 psig) inlet. Will vary based on thrust and side loads. For additional...

The pump will provide flow & pressure matching of pump output to system load demand, maximizing efficiency and improving load metering characteristics of any directional control valve installed between the pump and the load . Load sensing ensures that the pump always provides only the amount of flow needed by the load . The pump operating pressure adjusts to the load pressure plus a pressure differential required for the load sense margin . When the system is not demanding flow, the load sense control will operate in low pressure zero flow, energy saving stand-by mode . The differential pressure...

The pump will provide a continuously modulated flow to meet changing load demands at a pre-adjusted compensator pressure . At pressures below the compensator setting, the pump will operate at maximum displacement . See model code position #16, 17 for compensator pressure ranges . Warning: 1 . When adjusting the pressure limiter, install a 0 to 350 bar (0 to 5000 psi) gage in the outlet gage port and limit the pressure setting to the continuous rated pressure for the pump displacement . It is possible to adjust the pressure compensator beyond the rated pressure of the pump . Doing so, may void...

The Torque Control limits the torque input to the pump preventing the engine from stalling while also optimizing the use of the engine power. When combined with Pressure Compensator Control and/or Load Sense, it will allow the pump to remain inside the power envelope of the Pressure Flow curve . When the combination of pump flow and outlet pressure moves outside the envelop the pump displacement will automatically be reduced . This maximum setting is easily calculated using the following steps: • Select the 620 pump displacement you intend to use • Identify the available engine horsepower (HP)...

Pump displacement can be controlled infinitely, as per the current signal provided to the solenoid control valve . The integrated pump control makes use of an external current signal to vary the pump displacement . This control has an proportional characteristic i . e . with increasing current signal, the displacement increases proportionately This control is with manual override . Based on fail safe condition there are two types: Min type (EP): Return to min displacement in case of power loss . Max type (EPD): Return to max displacement in case of power loss Warning: 1 . When adjusting the pressure...

The EH Inverse Proportional Pressure control allows for stepless variation of the max pump output pressure, as per the current signal provided to the control valve solenoid . The integrated pump control makes use of an external current signal to vary the pump output pressure This control has an inverse proportional characteristic i . e . with increasing current signal, the max output pressure is proportionately reduced Warning: 1 . When adjusting the pressure limiter, install a 0 to 350 bar (0 to 5000 psi) gage in the outlet gage port and limit the pressure setting to the continuous rated pressure...
