The Grundfos CM Booster Self-Priming is a compact booster pump designed for domestic and light industrial use. The booster unit consists of a robust multistage centrifugal pump and a generator friendly PM1 or PM2 pressure manager. The pressure manager allows the pump to start and stop automatically according to demand and protects the pump from dry running. The CM Booster Self-Priming Pump is the perfect solution if you are struggling with insufficient mains pressure, and can also be used with above or below ground water sources. The 3-47 model is suited to high pressure requirements for example multi level houses and long runs of pipe.
