Grundfos CM and CME pumps are horizontal end-suction multistage centrifugal pumps. The pumps are of close-coupled type and come in both self-priming and non-self-priming versions. CM pumps are driven by AC motors, while CME pumps are equipped with integrated frequency converters. Both CM and CME pumps feature mechanical shaft seals.

The CM pump is specially developed to meet the diverse needs of various customers. At least five patent applications have been filed during the development process of the pump. The CM pump is available in various sizes and stages to meet different flow and pressure requirements. The CM pump mainly consists of two major components: the motor and the pump unit. The motor is a Grundfos motor that complies with EN standards. The pump unit adopts the best hydraulic system and can be connected in different ways. The pump has many advantages, some of which are listed below and are described in detail in the Features and Benefits section on page 9:
• Compact structure
• Widely adopted globally
• High reliability
• Easy maintenance
• Wide performance range
• Low noise
• Customized solutions.
