The Grundfos CMBE Twin is a booster pump for water supply and commercial boosting applications. The CMBE Twin Booster system consist of two CMBE pumps connected in parallel and mounted on a base plate with a Grundfos built manifold. The CMBE pumps will alternate to ensure the same number of operating hr until high flow is needed and the pumps will run together. The CMBE twin offers constant pressure and high comfort thanks to the variable-speed motor, noiseless operation and built-in protection against dry running. A pressure sensor monitoring the discharge pressure allows for the CMBE twin to adjust motor speed or signal for the second pump to start, adapting to changing system demands.
