Grundfos CMBE TWIN 3-93 I-U-C-C-D-A Variable Speed Constant Pressure Pump 99282855
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:
- CME pump with integrated frequency converter
- 5-way valve
- expansion tank
- pressure gauge

• Constant pressure via integrated speed control
• Cascade control and pump alternation
• Dry-running protection
• Compact
• Robust, stainless steel design
• Easy installation
• Low energy consumption
• Noise level below 55 dB(A) and even lower at controlled speed
Thermal protection CME Booster pumps require no external motor protection. The MGE motor incorporates thermal protection against slow overloading and blocking. Grundfos CMBE Booster is mainly used for domestic and light commercial water supply or booster systems.
