GRUNDFOS CMB-SP 3-47
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 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 is the perfect solution if you are struggling with insufficient mains pressure, and can also be used with above or below ground water sources.
Recommendation: A pressure tank extends pump life, stores energy, reduces noise, reduces pump starts and protects against heat expansion, see drop-down menu.
