A motor-driven centrifugal pump, mounted on a stainless steel plinth with a water reservoir and pipework for continuous circulation.

The pump volute and the water reservoir are manufactured from clear acrylic for maximum visibility. Similarly the pipe runs are made from transparent PVC. Manually operated valves at the pump inlet and outlet allow control of the flow and also facilitate the study of suction effects.

The pump volute has been designed so that the impeller can be easily accessed and replaced without tools.

The FM50 is delivered with two impellers, one with forward-curved blades and one with backward-curved blades, allowing the students to investigate the effects of impeller characteristics.

Demonstration Capabilities

• Demonstration of a single-stage centrifugal water pump in operation

• Measurement of constant-speed pump performance, including production of characteristic curves:

– Pump total head
– Motor shaft power
– Impeller speed
– Pump efficiency

• Introduction to pump speed laws

• Investigation of impeller styles

• Comparison of student calculations with computer results
