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 hours until high ow is needed, and the
pumps will run together.
The CMBE twin oers 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.
The integrated speed control enables the CMBE to maintain a constant
pressure in the pipe system and oers a solution for a variety of
applications such as:
• Apartment buildings
• Schools
• Small hotels
• Oce buildings
