Product Description
CMBE 3-62 I-U-C-A-D-A
The Grundfos CME Booster is a compact booster system for water supply in domestic applications. The integrated speed controller enables the CME Booster to keep constant pressure in the pipe system. A pressure sensor monitoring changes in the water consumption will signal to the speed controller to change the motor speed to adapt performance to the new state. The CME Booster is very easy to install. When the pipework has been installed, it is all a matter of plugging the unit into a socket, and the system is operational. The CME Booster consists of:
CME pump with integrated frequency converter
5-way valve
expansion tank
pressure gauge
Features
Constant pressure, integrated speed control
compact
robust, stainless steel
easy installation
dry run protection
Thermal protection CME Booster pumps require no external motor protection. The MGE motor incorporates thermal protection against slow overloading and blocking (IEC 34.11: TP
211).
Applications Grundfos CMBE Booster is mainly used for domestic and light commercial water supply or booster systems.
