Pressure Control Basic Model PM 1

The flexible basic model PM 1 is perfectly suited for applications where the pump needs to be turned on and off based on consumption. When the switch-on pressure is reached - either 1.5 or 2.2 bar depending on the version - the PM 1 activates the pump. The pump will then run until no more water is drawn. To enhance operational safety, the PM 1 pressure control protects the pump from dry running and indicates an alarm if the permissible number of switching cycles is exceeded. This basic model also features the renowned Grundfos quality, which ensures high flexibility and, thanks to its robust electronics, a very long service life.
