Grundfos CMBE 1-44 Booster Pump System

The CMBE Booster is designed for domestic and commercial water supply, pressure boosting, irrigation and dewatering applications.The CMBE series is available in both 1x110-120V (Grundfos 98810910) and 1x200-240V (Grundfos 98548109) 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 keeps a constant pressure in the pipe system. A pressure sensor monitoring discharge pressure will signal to the speed controller to change the motor speed to adapt the performance to the new situation.
