Optimising water pressure and minimising pump starts

Designed specifically for domestic, agricultural and light commercial applications, a CMB PT and 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.

Unlike the CMB PT set, the 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.

Maintain system pressure without starting the pump

When only a small amount of water is needed, the unit draws on the pressure tank first to sustain system pressure without needing to start the pump. Single-phase CM pumps incorporate current and temperature-dependent motor protection, so no external motor protection is needed.

A quieter pump

Low noise motor – PT below 55 dB (A), PS below 62 dB (A) – increases your comfort.

Easy setup

Simply connect the booster set to the pipework and power supply and you are ready to go. 

Long-life reliability

Dry-running protection ensures full pump life.
