Self-priming pumps - Type SMS

Self-priming centrifugal pumps type SMS use the same hydraulic as the centrifugal pumps type SM but are equipped with standard motors instead of block motors.

Self-priming centrifugal pumps of the series SM are single-stage horizontally mounted pumps. Because of their robust and durable construction the SM pumps can be used in a wide variety of applications. With the numerous variations and options available the pumps fulfill efficiently different flow rates and pressure requirements. While pumping highly polluted fluids, a suction height of up to 6 m can be reached effortlessly.
