HM 285

Piston Pump Demonstrator

Technical Description

The HM 285 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 a container for volumetric flow measurement. Electronic sensors provide the delivery pressure and the pressure in the cylinder; a position sensor is used to determine the position of the connecting rod and thus the volumetric displacement. 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. The following accessories are required for operation: an Interface Module (HM 280.01), Data Acquisition Card with Software (HM 280.03) and a Set of Connecting Cables (HM 280.04). This layout makes it possible to record measured values during the experiments, and process and store this data on a PC.
