Axial Piston Pumps P1/PD Series Design Series Change Information The P1/PD has gone through a design series change for some control options. All the controls shown in this catalog except the Electronic Displacement and Pressure Control options (P, S, T, U, AG, AH) are now standard as Design Series B (B-mod). For the C, L, and AM controls, the controls were combined into a single universal control housing that can be used for any of the three options. Therefore, converting between those controls is very easy. For conversion details or other service information on the B-mod, please refer to the...

Axial Piston Pumps P1/PD Series Pressure Limiter Load Sensing and Pressure Limiter Adjustment Range = 26-280 bar (380-4060 psi) Pressure Limiter Adjustment Range = 26-280 bar (380-4060 psi) Differential Adjustment Range = 10-40 bar (150-580 psi) 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...

Axial Piston Pumps P1/PD Series 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 to zero displacement...

Control Options “AMT,” “ANT,” and “LOT” Torque Limiting Controls: (45-140cc only) AMT = Remote pressure limiting with torque limiting ANT = Pilot operated pressure limiting with torque limiting LOT = Load sense & pressure limiting with torque limiting 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. “AMT” Control The "AMT" and "ANT" combine the pilot pressure limiter...

Axial Piston Pumps P1/PD Series Control Options “AE” and “AF” Electronic Proportional Pressure Limiting with Mechanical Pressure Limiter Minimum Pressure Default AE = 12 VDC Solenoid AF = 24 VDC Solenoid 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 that full pump displacement is achieved unless the system pressure reaches the setting of the proportional relief...

Axial Piston Pumps P1/PD Series B-Mod 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...
