Grundfos CM Booster Self Priming | CMB-SP 3-47
The Grundfos CM Booster Self-Priming is a compact booster pump designed for domestic and light industrial use. The booster unit consists of a robust multistage centrifugal pump and a generator friendly PM1 or PM2 pressure manager.

With a suction lift of up to 8 metres (self-priming up to 4 metres), the CM Booster Self-Priming is ideal for pressurising water from above or below ground water sources.
All wetted parts are made from high quality, corrosion resistant stainless steel to ensure the longest life possible.
The pump features a user-friendly interface with LED indicators displaying power status, pump running, alarm indication and pressure indication (excluding CMB-SP 1-36).
The pump incorporates a range of protective features such as; dry run protection, thermal overload protection, cycling alarm and maximum continuous operation time - 30 mins (excluding CMB-SP 1-36) to protect the pump and ensure a long life.
The booster unit is a compact and adaptable solution, which makes it suitable for most installations. Simply connect the inlet and outlet and adjust the start pressure to suit individual requirements and you have a fully operational booster unit.
