Centrifugal Pump Module


Centrifugal pumps are turbo machines that are used for conveying fluids. The FM 100.08 unit can be used to study a centrifugal pump and to record a typical pump characteristic curve. The experimental unit includes a self-priming centrifugal pump, a ball valve on the outlet side and manometers on the inlet and outlet side. It is driven by an asynchronous motor.

The speed is infinitely adjustable by using a frequency converter. A ball valve is used to adjust the head. In experiments, the operating behavior of the pump as a function of the flow rate is studied and displayed in characteristic curves. The motor’s speed and electrical power are displayed digitally. Pressures on the inlet and outlet side are displayed on two manometers.

The experimental unit is positioned easily and securely on the work surface of the HM 150 base module. The pump draws in water from the tank on the base module FM 100. The flow rate is determined volumetrically by flowing back into the measuring tank on FM 100.
