Grundfos CM-PS | CMB 5-47
The CM-PS is a compact booster solution designed for domestic and light industrial use. The booster unit consists of a robust CM pump, 5-way valve and a pressure switch. To complete the booster system a pressure tank must be fitted. The pressure switch and pressure tank ensure a convenient water supply with a minimum start/stop frequency.
All wetted parts are made from high quality stainless steel including the impeller, pump housing and shaft to ensure the longest life possible.
The built-in pressure switch automatically starts and stops the pump according to demand.
The booster unit is a compact solution, which makes it suitable for most installations. Simply connect your own pressure tank, inlet and outlet, and you have a fully operational booster unit.
Great system comfort
The diaphragm tank increases system comfort by limiting the switching frequency of the pump and compensating for pressure drops when a tap is opened. It also reduces problems with water hammer in the pipework.
The single-phase CM pump is effectively protected against any accidental overload, by built-in thermal and current protection. This means that no additional motor protection is required.
