This is an invaluable aid in the effective understanding of the performance characteristics of a variety of pumps. The electric motor (AC or DC) is used as a drive unit. The unit has a facility to measure the power consumed by the drive, pump speed, flow rate and pressure.

Optionally, it has a facility to vary the speed of the motor to get various performance parameters for better understanding.

Various pumps like vane pump, gear pump can be studied.
