CMBE TWIN is a high-efficiency booster system consisting of two Grundfos CMBE boosters connected in parallel, suitable for clean water supply and pressure boosting in domestic and commercial applications.
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 Booster to maintain constant pressure in the pipe system. A pressure sensor monitoring changes in the water consumption will signal the speed controller to change the motor speed. This way performance is adjusted according to the new state, thus running in cascade multi-pump. The cascade control ensures that the performance of the CMBE Booster is automatically adapted to consumption by switching pumps on or off and by changing the speed of the pumps in operation. The system thus runs as energy-efficiently as possible with a limited number of pumps. The CMBE-TWIN Booster is very easy to install. It has UL approval.
The CME Booster consists of 2 units of CMBE Booster which each include, 5-way valve, expansion tank, pressure gauge, Pressure sensor.
Features:
Applications:
Thermal protection CME Booster pumps require no external motor protection. The MGE motor incorporates thermal protection against slow overloading and blocking (IEC 34.11)
