The MP73 bench allows the study of an industrial centrifugal pump alone or two pumps mounted either in series or in parallel. Designed to operate in a closed circuit, it is a complete experimental tool for studying the performance and characteristics of centrifugal pumps. With its feed tray, it is hydraulically autonomous and requires only a power supply. It can be easily used in a workshop or classroom. The bench has two similar centrifugal pumps but different powers. The speed of both pumps is regulated by an electronic dimmer with display of speed and power consumption. Complete instrumentation with pressure gauges and flowmeters allows you to determine the hydraulic power and plot the characteristic curves of the pumps.
