Grundfos JP PM Booster provides the comfort of constant water pressure with automatic start and stop controlled according to consumption by the intelligent pressure manager. JP PM includes dry-running protection that automatically stops the pump in case of dry running. 

This means lower risk of pump damage and lower maintenance costs. The anti-cycling function will stop the pump in time in case of a minor leakage in the system, or if a tap has not been closed completely. When cycling occurs, the pump stops, and an alarm will be indicated. A non-return valve for backflow prevention is already integrated.

JP PM consists of a Grundfos JP pump and a Grundfos Pressure Manager PM 1. JP pump is a self-priming, single-stage centrifugal jet pump. The jet pump has excellent suction capacity and is designed for long and trouble-free operation. The built-in ejector with guide vanes ensures optimum self-priming properties. The pressure manager starts the pump at 1.5 bar and the pump keeps running as long as there is flow. 

The design is robust and built upon corrosion-free materials to ensure a long lifetime. This booster set ensures optimum self-priming properties, featuring a suction-lift up to 8 meters. The self-priming pump also ensures a stable operation as is it able to lift liquid from below the inlet level and can handle a mix of air and liquid until the pump reaches a fully-primed pumping condition.

The JP pump has built-in thermal protection, which immediately stops the pump if it overheats. The motor is air cooled and equipped with oversized, sealed, greased-for-life ball bearings to ensure silent operation and minimum service.
