The single vane pump control valve is designed to limit the flow to 55 GPM. Excess flow is re-circulated
to the inlet.
The pump ON/OFF valve must have power to turn the pump ON.
When the pump solenoid is in the OFF mode, oil is allowed to circulate back to the inlet.
The maximum pump speed is controlled by the PLC.
