The Grundfos PM 1 and PM 2 Pressure Managers are designed for automatic start/stop control of Grundfos pumps and other water supply pumps.
The PM 1 and PM 2 have a user-friendly interface with LED indicators showing:
pressure indication (PM 2)
The PM 1 and PM 2 can be freely positioned in the installation- vertically, horizontally, or at an angle. This makes it easier to install the units in confined spaces and in extensive existing pipework. Due to robust electronics, the PM 1 and PM 2 can be powered by a generator or other alternative power supplies.
Both pressure managers incorporate a number of functions which protect both the pump and the installation. Protective features:
maximum continous operating time (30 minutes)(PM 2)
The PM 2 has an auto-reset function which can be used to automatically restart the pump.
