Grundfos PM2 pressure manager is an electronic pressure manager primarily for controlling Grundfos pumps, but it can also be used for other water supply pumps.
The pressure manager offers an adjustable start from 1.5 to 5 bar, allowing for adaptation to the individual installation.
The installation can be done either vertically, horizontally, or at an angle, if the space is confined.
The display can be adjusted within 360 degrees to always have the optimal viewing angle.
When the start pressure is reached, the pump is started and kept running as long as the pressure manager senses a flow. The pressure manager has an electronic interface with LED indicators, which shows the status for power on, pump running, and alarm indication. The pressure manager incorporates functions for pump and installation protection. These functions are dry running protection, cycling alarm, and maximum continuous operation time of 30 minutes. A non-return valve for backflow prevention is already integrated.
The pressure manager can be optimised for operation with a large external pressure tank by enabling the 1 bar differential pressure function.
This significantly reduces the number of operating hours of the pump in installations with a pressure tank.
Additionally, the pressure manager features an LED pressure indication.
