Datasheet download
Download PDFGrundfos PM 2 Pressure Control Unit is suitable for the automatic switching on or off of a pump (e.g., for household water supply). The unit is therefore ideal for applications where the pump needs to be activated according to the current water demand.
The pump is activated at an adjustable pressure of 1.5...5 bar. The PM 2 unit switches on the pump when the set pressure is reached, and the pump remains operational until a low flow is achieved.
The activation pressure is set using DIP switches located behind the control panel. The current pressure is displayed on an LED scale.
The PM 2 control unit can be configured for operation with an external pressure tank using a differential pressure function of 1 bar. This feature reduces the number of operating hours of the pump in applications with a pressure tank.
