CENTRIFUGALPUMP DEMONSTRATION

The centrifugal pump is the machinemost commonly used to move liquids from one place to another.

As such it is a particularlyinstructive unit with which to introduce students to the whole subject of rotdynamic fluid machines.

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

The pump volute and the waterreservoir are manufactured from clear acrylic for maximum visibility.

Similarly the pipe runs are made fromtransparent PVC. Manually operated valves at the pump inlet and outlet allowcontrol of the flow and also facilitate the study of suction effects.

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

This is delivered with two impellers,one with forward curved blades and one with backward curved blades, allowingthe students to investigate the effects of impeller characteristics.

Electronic sensors measure the pumpinlet pressure, the pump outlet pressure, the flow rate and the watertemperature.
