Pressure build-up

Item	Description
A	Barometric Pressure

Drive	Operating pressure

The pump plungers generate the operating pressure that is controlled by the control valve as a function of the difference in speed between the input and output shafts. The control valve works progressively from fully open to fully closed. The fluid pressure can be approx. 67 bar when the control valve is fully open. The maximum pressure is mechanically controlled by means of the pressure relief valve.
