Product description
The Grundfos PM 2 pressure controller is designed to automatically switch on and off Grundfos pumps and other water supply pumps. The device offers an adjustable switch-on pressure range of 1.5 to 5 bar, which allows it to perfectly adapt to the specifics of each installation and increase user comfort
The cut-in pressure is set using DIP switches located behind the control panel, and the current pressure value is displayed on an easy-to-read LED display located on the front of the unit. The controller starts the pump when the set pressure value is reached, and shuts it down if there is no flow
The PM 2 can be adapted to work with an external pressure tank by activating the on/off function at a pressure difference of 1 bar, which significantly reduces the pump's operating time in installations with such tanks. In addition, the unit is equipped with safety functions such as dry-running protection, alarm signaling and a maximum continuous operation time limit of 30 minutes
