Description
Grundfos pressure managers PM1 and PM2 are designed for automatic start/stop control for Grundfos pumps and third- party water supply pumps. Grundfos PM 2 pressure manager is an electronic pressure manager for controlling, primarily, Grundfos pumps, but can also be used 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. 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. Pressure managers are available as a stand-alone solution for a new or retrofit installation, or as part of a Grundfos domestic water solution.
