Centrifugal Pump Demonstration - Application: Fluid Mechanics Lab Equipments

The centrifugal pump is the machine most commonly used to move liquids from one place to another.
As such it is a particularly instructive unit with which to introduce students to the whole subject of rot dynamic fluid machines.
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.
This 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.
Electronic sensors measure the pump inlet pressure, the pump outlet pressure, the flow rate and the water temperature.
