PFC Axial Piston Pump Manual Extract

Product Overview

This manual provides essential information on the PFC Axial Piston Pump, emphasizing its operational principles relevant to standard, high flow, and Twin Flow pump systems. The guidelines included primarily illustrate the standard flow pump model.

Principle of Control

The pump is equipped with several signal ports integrated into various components, such as remote valves, hitch control valves, a trailer brake option, and a Power Beyond circuit, if installed. Each signal port communicates the working pressure of its respective circuit through signal lines to the pump compensator spool. This input directs the swash plate to adjust its angle appropriately to meet system demands efficiently.

Check valves are installed in each signal line, ensuring that when multiple control valves are actuated, the highest pressure signal remains active. This design prevents pressure bleed-off and maintains optimal system performance by applying the highest pressure signal to the compensator spool.

Operating Modes

Low Pressure Standby

In low demand conditions, the pump maintains a minimal flow to compensate for internal leakage, operating at low pressure and requiring minimal power.

Pressure and Flow Delivery and Compensation

When flow and pressure demand arises from the hydraulic system, the pump adapts to provide only the necessary amount of flow. This operation limits the power required by the system, enhancing efficiency.

Key Features

• Signal ports included in remote and hitch control valves and Power Beyond circuits.
• Single check valve for each signal line connection to the compensator spool.
• Adaptable swash plate angle to meet varying system demands.

Benefits

• Ensures maximum efficiency by regulating only the required flow and pressure.
• Prevents signal bleed-off and maintains system integrity under multiple control valve operations.
• Minimizes power consumption during low-demand periods.

Usage Recommendations

• Ideal for systems requiring variable flow and pressure control.
• Applicable in hydraulic setups with multiple control valves.
• Ensure proper installation of check valves to maintain pressure integrity.
