Centrifugal pumps

In industrial installations, fluid transport/flow in pipes, reactors, and filters, etc.

requires energy transferred to the fluid. This energy is supplied by pumps which

enable the different pressure losses in the circuit to be overcome.

Choosing the right pump and right pump technology is therefore essential.

The main objective of this pump study bench is to familiarize the operator

with the various notions associated with using a centrifugal pump,  and more

particularly that of pressure (head) available at the pump output.

Plot the characteristic graph at various speeds

Observe cavitation

Determine yield electrical consumption/hydraulic power
