Pressure controller PM 1 22 1x230V 50/60Hz 96848722

The Grundfos PM 1 pressure controller is designed for automatic start / stop of Grundfos pumps and other water supply pumps.
The PM 1 is suitable for installations where the pump is on / off according to water consumption. It is the basic control system that switches the pump on at 2.2 bar. The PM 1 starts the pump when the start pressure value is reached and stops it when there is no flow. The PM 1 also offers dry running protection and alarm signaling for increased safety.
