The Reciprocating Pump demonstration unit enables the pump curve of a reciprocating pump to be measured. The system consists of the pump with an electrical drive motor, the pipe system with supply tank and optional a container for volumetric flow measurement. Gauges provide the delivery pressure and the pressure in the cylinder.
The pressure level in the system is maintained constant using a pressure retention valve. The pulsating pressure characteristic of the pump can be damped with an air vessel.
