CMBE is a high-efficiency compact booster suitable for clean water supply and pressure boosting in domestic and light commercial applications. It keeps constant pressure via the integrated speed control.
Suitable for.
The Grundfos CMBE booster is a compact booster system for water supply in domestic applications. The integrated speed controller enables the CMBE booster to keep constant pressure in the pipe system. A pressure sensor monitoring changes in the water consumption signals the speed controller to change motor speed to adapt performance to the new state.The CMBE booster is very easy to install. When the system has been connected to the pipes, it is all a matter of inserting the plug into a power supply socket, and the system is operational. The CMBE booster consists of the following:
The Grundfos CMBE booster requires no external motor protection. The MGE motor incorporates thermal protection against slow overloading and blocking (IEC 34.11: TP 211).
The Grundfos CMBE booster is mainly used for domestic and light commercial water supply or booster systems.
