The Grundfos PM Plus is a controller that allows your pump to operate "on demand". On demand essentially means that when there is a drop in pressure in the water line, the PM Plus will send a signal to the pump to turn on and begin pushing water. The pressure drops until it reaches 20 PSI to 32 PSI (1.5 or 2.2 bar), then starts the pump. The pump will continue to run until the demand for water stops. E.g. A valve is closed, and the flow of water ends. At this point, the PM Plus will send a signal to turn off the pump.
The Grundfos PM Plus pressure manager is designed for automatic start/stop control of Grundfos pumps and other water supply pumps. The PM Plus is the all-round control solution offering adjustable start from 21-43 PSI. This enables customization to different types of installations at the desired comfort level. The start pressure is set by means of DIP switches located behind the control panel, whereas the current pressure is indicated on the LED display on the front of the PM Plus. The PM Plus starts the pump when the start pressure is reached, and the pump keeps running as long as there is a flow. The PM Plus can be optimized for operation with an external expansion tank, reducing the number of times the pump starts/stops, extending the life of the pump.
Grundfos PM PLUS
Optimized home water pressure
The Grundfos all-in-one PM PLUS pressure manager works with domestic water supply pumps from Grundfos or any brand, automatically starting the system pump at a preset pressure point and continuing for as long as the water flows.
It ensures optimal water pressure wherever and whenever it’s needed around the home, solving issues such as fluctuating or insufficient water pressure. Easy to install and safe to run, the PM PLUS includes such features as dry-running protection.
Adjustable start pressure
When you connect PM PLUS with your water supply pump, it will start the pump at your preferred cut-in pressure level – from 21 - 43 PSI. It then keeps the pump running as long as there is a sufficient flow of water.
