A small two-booster system for water supply in residential and commercial settings is the Grundfos CMBE TWIN booster. The CMBE TWIN booster can keep the pipe system's pressure steady thanks to the inbuilt speed controller. Through cascade multipump operation, the CMBE TWIN booster provides parallel operation. By turning the pumps on and off and altering their operating speed, this feature makes sure that the CMBE TWIN booster's performance is automatically adjusted to consumption. The speed controller is alerted to alter the motor speed by a pressure sensor that tracks variations in water usage. Thus, with the number of pumps needed, the system operates as energy-efficiently as possible. The CMBE TWIN booster is UL approved and incredibly simple to install.
There are two CMBE booster units in the CMBE TWIN booster, and each one has the following options:

  1. Five-way valve.
  2. expansion tank.
  3. gauge for pressure.
  4. sensor of pressure.
  5. a foundation frame.
  6. A pair of cables.
No external motor protection is necessary for the Grundfos CMBE TWIN booster. Thermal protection against gradual overloading and blocking is built into the MGE motors (TP 211, per IEC 34-11). The primary applications for the Grundfos CMBE TWIN booster are light business and residential water supply or booster systems.

Including inlet pipe pressure loss at a liquid temperature of 20 °C (without self-priming), the maximum suction lift is 1 m.
