Plunger Pump Demonstration Unit

• A small-scale plunger pump demonstration unit, comprising of a water reservoir, pump, control valve, relief valve and interconnecting pipe work, 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 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.
