Description
Grundfos CMBE 1-44
The Grundfos CMBE 1-44 Booster is designed for domestic and commercial water supply, pressure boosting, irrigation, and dewatering applications. The CMBE series is available in both 1x110-120V and 1x200-240V variants and uses energy-efficient, permanent magnet motor technology, which provides unmatched reliability, quiet operation, and energy savings. Thanks to the integrated speed controller, the CMBE 1-44 keeps a constant pressure in the pipe system. A pressure sensor monitoring discharge pressure will signal the speed controller to change the motor speed to adapt the performance to the new situation.
