Description

The Grundfos CMBE TWIN booster is a compact two-booster system for water supply in domestic and commercial applications. | The integrated speed controller allows the CMBE TWIN booster to maintain constant pressure in the pipe system. The CMBE TWIN booster offers parallel operation via cascade multipump operation. This feature ensures that the performance of the CMBE TWIN booster is automatically adapted to the consumption by switching pumps on or off and by changing the speed of the pumps in operation. A pressure sensor monitoring changes in the water consumption signals the speed controller to change the motor speed. The system therefore runs as energy-efficiently as possible with the number of pumps required. The CMBE TWIN booster is very easy to install, and it is UL approved. The CMBE TWIN booster consists of 2 units of CMBE booster which each include the following:
