CM multi-stage pumps are compact and flexible

The CM is a horizontal close-coupled multi-stage pump, designed to fit seamlessly with other components in small and large systems or as a stand-alone pump. CM stands for Centrifugal Modular – a series of interchangeable modules in the pump that make it suitable for applications such as washing and cleaning, temperature control, water treatment, chemical and pharmaceutical industry. The CM is built to be extremely compact, quiet and reliable, ensuring years of easy operation with minimum need for servicing and spare parts.

When customisation and flexibility are key

Thanks to numerous configuration options and a range of materials, the pump can operate in temperatures from -30 °C to 120 °C. It is also available with a variety of customisation possibilities, such as oversize motors when the liquid viscosity and density is high. 

Reliable and safe

CM pumps are available in cast iron or stainless steel, in variants suitable for water and non-corrosive liquids, or for aggressive liquids. They are also available with drinking water approvals. 

Easy startup

The pump also comes in a self-priming variant, which can create a suction lift of up to eight metres in less than five minutes.


Clamping of the pump impellers and washer makes the pump extremely robust and reliable.
