GRUNDFOS CMBE 5-62 VARIABLE SPEED BOOSTER PUMP

Grundfos CMBE 5-62 Variable Speed Booster Pump

The Grundfos CMBE 5-62 is a compact booster system for water supply in domestic and light commercial applications. Featuring an integrated speed controller, it automatically adjusts pump speed to keep pressure constant at every tap — regardless of variations in demand or inlet pressure — helping lower energy costs while improving comfort and reliability.

Smart, Efficient Pressure Control
A pressure sensor continuously monitors changes in water consumption and signals the speed controller to adjust motor speed accordingly, keeping the pipe system at constant pressure at all times.

Built to Last
All wetted components are constructed from high-quality 304 stainless steel, ensuring water quality isn't affected by pump materials and giving the pump long-term durability. Thermal protection is built into the motor, requiring no external motor protection.

Quiet, Simple Operation
Operating at 50-60 dB, the CMBE 5-62 is noticeably quieter than most conventional pumps. Installation is straightforward — once connected to your pipework, it's simply a matter of plugging in and the system is operational.

Protected Performance
Includes dry run protection to automatically stop the pump if the water source runs dry, plus overload protection.
