SERIES AND PARALLEL PUMPS DEMONSTRATION UNIT FM51

• 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

• 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
