The Grundfos CM/CME pump has been created with compactness, flexibility and reliability as its central features. This horizontal multistage close-coupled pump is a compact, reliable and quiet pump designed to work in a variety of applications.

The difference between the CM and the CME pump ranges is the motor. CM pumps are fitted with mains-operated motors, whereas the motors for CME pumps have an integrated frequency converter and PID controller.

A Grundfos engineered mechanical shaft seal has been designed to eliminate industry-wide problems with shaft seals sticking where SIC-SIC seal faces are used.  The solution builds on both the implementation of a rotation stop on the stationary ring and different surface finishing on both the stationary and rotating rings.

The CM and CME pumps are available in cast iron or stainless steel
