Features:
A small-scale plunger pump demonstration unit, comprising of a water reservoir, pump, control valve, relief valve, and interconnecting pipework, all mounted on a stainless steel base. ? Includes both a sprung loading valve and a needle valve for loading the pump.
Equipped with electronic measurement sensors for cylinder pressure, plunger position, pump outlet pressure, and cumulative flow.
Pulsation damping facility.
Transparent pump head for visibility.
Capable of being linked to a PC (not supplied) via an interface console (an essential accessory).
Supplied with optional software providing full instructions for setting up, operating, calibrating, and performing the teaching exercises. Facilities provided for logging, processing, and displaying data graphically.
Full theoretical back-up included together with a student questions and answers session
visibility. The pump outlet is connected to both a sprung loading valve and a needle valve to investigate different loading characteristics. A pressure relief valve protects the operator and the equipment. An additional valve can be used to isolate or include the pulsation damper, allowing the effect of damping to be investigated
Electronic sensors measure the instantaneous cylinder pressure within the pump, the pump displacement, and the cumulative flow over a period of time.
