Applications :
- 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 :
- Self Priming
With a suction lift up to 8 meters (self-priming up to 4 metres), the CM Booster Self Priming is ideal for pressuring water from above or below ground water sources - Robust design
All wetted parts are made from high quality, corrosion resistant stainless steel to ensure the longest life possible - User-friendly interface
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)
