CMB3-37 A-C-A-A-A-A Pressure Pump 97530133

The Grundfos CM Booster with pressure manager PM1 is a compact booster set for water supply in domestic applications. The pressure booster unit consists of a Grundfos CM pump and a Grundfos pressure manager PM1. The pressure manager allows the pump to start and stop automatically according to demand and protects the pump from dry running. The CM Booster is very easy to install. When the booster has been connected to the pipework, it is all a matter of plugging the plug into a socket, and the system is operational.

  1. Peter Skands (verified owner)

    Perfect pump for my rainwater tank to feed suburban garden sprinklers, irrigation system, and laundry. I wanted a low noise pump since it is close to bedrooms and neighbouring gardens – and this really delivers. Barely audible I don’t think my neighbours even know it’s there, and we certainly can’t hear it from our bedroom. Top quality, has been running flawlessly.
