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

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.
