The pump is a self-priming design. Experiments can be performed with the pump on its own, or in series with the pump on the HM 150 bench. Drive is provided via a speed-controlled asynchronous motor with frequency converter. The speed and the electrical power at the motor are displayed digitally. Two manometers indicate the suction and delivery pressure. The water supply and volumetric flow rate measurement are provided by the HM 150 Basic Hydraulics Bench.
Learning Objectives / Experiments
