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: Connect inlet and outlet to pipe, connect power, check tank pressure, ensure suction side is debris free to avoid damage to impellers or clogging, set pressure on controller.
