The Grundfos CM Booster is a horizontal multistage centrifugal pump designed for domestic and light industrial applications. It is suitable for pressure boosting from above ground rainwater tanks or from mains water. The Grundfos CM Booster with Pressure Manager is a compact booster pump for water supply in domestic applications. The Pressure Manager allows the pump to start and stop automatically according to demand and protects the pump from dry running. Coupled with Pressure Manager, the CM Booster provides reliable pressure boosting and water supply while minimising annoying shower temperature fluctuations.
The Grundfos CM Booster Self-Priming is a compact booster pump designed for domesticand light industrial use. The booster unit consists of a robust multistage centrifugal pump and a generator friendly PM1 or PM2 Pressure Manager.The Pressure Manager allows the pump to startand stop automatically according to demand andprotects the pump from dry running. The CM Booster Self-Priming is the perfect solution if you are struggling with insufficient mains pressure,and can also be used with above or below groundwater sources.
- – Mains water pressure boosting
- – Rainwater supply from above ground water tanks
- – Rainwater supply from below ground water tanks
- – Rainwater supply from other below ground water sources – dams/rivers etc.

Features and Benefits
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.
Integrated non-return valve
Non-return valve for backflow prevention.
