GRUNDFOS PUMP CMB-PS  Booster self-priming pump compact boosters with pressure switches suitable for domestic and agricultural applications and installations where small leakages are expected to occur. CMB PT includes a pressure tank.



The Grundfos PUMP CMB-PS Booster pump specifically for domestic, agricultural and light commercial applications, a CMB PS booster set ensures that you get optimal water pressure where and when you need it. These booster sets utilise a pressure tank to release stored pressure into the system when small amounts of water are needed, thereby maintaining system pressure while reducing the number of pump starts.

CMB PS comes without a pressure tank, meaning that a tank must be fitted to complete the booster system. Both sets come with dry-running protection and are very easy to install. Simply connect the unit to the pipework and power supply and you are ready to go.
