Grundfos CMB(E) Horizontal Multistage Booster Pumps

The Grundfos CMB(E) pumps are designed for use in domestic hot water supplies. These multi-stage centrifugal booster pumps are fitted with a pressure manager. This enables the system to automatically stop and start depending on the demand. It also prevents the pump from dry running.

There are three models within the range: CMB1, CMB3 and CMB5. They can be fitted into a number of different settings, ranging from small family homes and apartment buildings to schools and offices. The pumps have integrated motor protection and no additional protection is required. The system alarms are automatically reset when they have been activated.

The CMB(E) range has a compact design, but still offers excellent levels of performance. They are easy to fit, as the pumps are simply joined up to the existing pipework. Once the system is plugged in, it's ready to use. They have a modular design, allowing a range of configurations to be achieved. The pumps consist of changeable components, which all work together whatever setting they are used in.

These pumps are of the close coupled type. The motor within the CMB(E) range is mains operated. The pumps are manufactured from stainless steel or cast iron and the shaft seal is mechanical. Cast iron is an exceptionally strong and reliable material, whereas stainless steel offers high levels of corrosion resistance. These reliable systems operate with minimal noise, which is a distinct advantage when fitted into confined spaces. They have a high quality hydraulics system and can be used on their own or as part of an integrated system.
