Grundfos CM Series Booster Pumps Buyers Guide & Review
| Made By : admin

Grundfos CM end suction multistage centrifugal booster pumps are designed for a variety of washing, cleaning, water treatment, heating, cooling, and irrigation applications. CM pumps are often used in chemical and pharmaceutical processing settings, as well as in building services.

Compactness, flexibility and reliable pumping performance are some of the hallmarks of the Grundfos pump oeuvre and the CM series is no exception. The simple design also makes CM pumps service friendly and easy to install. A reduced footprint, low maintenance costs, reduced downtime, low noise level and a wide performance range are all features of these fantastic pumps. Of particular note is the Grundfos engineered mechanical shaft seal, which has been designed to eliminate the common industry problem of shaft seals sticking where SIC-SIC seal faces are in use. A different surface finishing on the stationary and rotating rings eliminates the sticking problem.

Please note that booster pumps have no lift capability and should not be run dry. Do not deadhead the pumps.
