The Grundfos PM 1 pressure manager is designed for automatic start/stop control of Grundfos pumps and other water supply pumps.
The PM 1 is suitable for applications where start/stop of the pump according to consumption is needed. It is the basic control solution offering start at 1.5 bar bar. The PM 1 starts the pump when the start pressure is reached, and the pump keeps running as long as there is a flow.
The PM 1 offers dry-running protection and cycling alarm for increased safety.
