Grundfos Pressure Control Unit PM 1/2.2 is suitable for the automatic switching on or off of a pump (e.g., for household water supply). The unit is therefore suitable for applications where the pump needs to be activated based on the current water demand.

Function

The pump is activated at a pressure of 2.2 bar. The PM 1 unit switches on the pump when the switching pressure is reached, and the pump remains in operation until a low flow is achieved.

The control unit includes dry-running protection and an anti-cycling function.
