A small-scale series/parallel pump demonstration unit, comprising of a water reservoir, two pumps, control valves and interconnecting pipework, all mounted on a stainless steel base.
Equipped with electronic measurement sensors for pump head pressure (2 off), suction, flow- rate and water temperature.
Transparent pump volutes for visibility.
Inlet valve throttling demonstrates air release.
Supplied with different easily interchangeable impellers.
Capable of being linked to a PC (not supplied) via a dedicated interface console.
Supplied with software providing full instructions for setting up, operating, calibrating and performing the teaching exercises. Facilities for logging, processing and displaying data graphically.
INSTRUCTIONAL CAPABILITIES
Demonstration of either series, parallel or single pump operation
Measurement of constant-speed pump performance, including production of characteristic curves (one pump)
Comparison of head-flow characteristics with single pump operation, at inherent speed
Investigation of impeller styles
Comparison of student calculations with computer results
