Axial Piston Pumps P1/PD Series Controls Information Control Option “C” The "C0" pressure limiter control is used to limit the maximum system pressure. The control acts such that full pump displacement is achieved unless the system valve restricts the output flow or the load pressure reaches the maximum setting of the control. If pump flow is restricted by the system valve, the pump will provide only the flow demanded, but at the maximum pressure setting of the compensator control. If the outlet flow is completely blocked, the pump will destroke to zero displacement and maintain the pressure...

Axial Piston Pumps P1/PD Series Controls Information The "AM" control allows the pump pressure compensator setting to be adjusted from a remote relief valve that is connected to the "X" port on the control. The control acts such that full pump displacement is achieved unless the system valve restricts the output flow or the load pressure reaches the maximum setting of the control. If pump flow is restricted by the system valve, the pump will provide only the flow demanded, but at the maximum pressure setting of the compensator control. If the outlet flow is completely blocked, the pump will destroke...

Axial Piston Pumps P1/PD Series Controls Information Torque Limiting Controls: (45-140cc only) AMT = Remote pressure limiting with torque limiting ANT = Pilot operated pressure limiting with torque limiting L0T = Load sense & pressure limiting with torque limiting "L0T" Control These controls provide the benefit of pressure limiting control, plus the ability to limit the input torque when the power available from the prime mover is limited; or when the application power demand has both high flow/low pressure and low flow/high pressure operating conditions. The "L0T" combines the functions of...

Axial Piston Pumps P1/PD Series Controls Information Electronic Proportional Pressure Limiting with Mechanical Pressure Limiter Minimum Pressure Default AE = 12 VDC Solenoid AF = 24 VDC Solenoid Note: The pressure relief valve has a command range up to 350 bar, but P1/PD pump is rated to 280 bar continuous pressure. This control is the same as the AN control, but with the proportional relief valve included. It allows the pump pressure compensator setting to be adjusted by an on-board 4VP0150G24B1C1 (24V) or RE06M35W2N1KWXG087 (12V) proportional, electronic relief valve. The control acts such...

Axial Piston Pumps P1/PD Series Controls Information Electronic Unload/Cold Start C03 = Pressure limiting with 12VDC unload valve C06 = Pressure limiting with 24VDC unload valve L03 = Load sense & pressure limiting with 12VDC unload valve L06 = Load sense & pressure limiting with 24VDC unload valve “L03” & “L06” Controls - Load sensing & pressure limiting with unload function When the unload valve is in the spring position (de-energized), the pump is “loaded”. The load sense function requires the signal port be connected to load pressure, and the valve sends the load pressure to the spring side...
