Control options Pressure & Flow (Load Sense) Compensator for AEC018 AG variant only The Agricultural tractor variant of 220 pump has a shuttle valve integral into pump end cover which senses the highest load of the two-work circuit and a priority valve to set the flow priority. For tractor application steering is given priority over other auxiliary functions like hitch circuit for implements. Fluid output from the pump end cover enters into the priority valve before reaching to system. Integrated priority valve gives the pump flow priority to Steering system over the Hitch valve of the tractor....

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: • 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...

Remote relief valve is to be connected to pilot port "J" through necessary external piping . Standard differential pressure of 20 bar is set at RPC spool . The required outlet pressure (below 280 bar) can be set by adjusting remote relief valve setting . Once pressure reaches preset value, flow across remote relief valve starts, this results in RPC spool movement due to pressure imbalance . This will de-stroke the pump to maintain the set pressure Secondary fixed pressure compensator is provided to limit the max pressure setting as a fail safe measure Note • Flow Compensator is not available...

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: • When adjusting the pressure...
