The new Grundfos CR is for engineers who like to move the limits
Meet the new generation of Grundfos CR pumps – the more efficient, more robust upgrade on the world’s most modular pump range. The new CR 95, CR 125 and CR 155, replacing the existing CR 90, CR 120 and CR 150, feature a new hydraulic design that improves everything from impeller and guide vanes to inlet, discharge port, sleeve and diffuser – giving you world-class energy efficiency and improving pump reliability even more than before. The new CR range moves the limits of performance.
The optimised hydraulic design of the new generation of CR pumps is made possible with advanced simulation-driven design and validation processes. An automated design loop generated thousands of virtual prototypes to perfect impeller blades, guide vanes, flow paths and passages and reduce turbulence and energy/pressure losses – bringing to life a pump with world-class energy efficiency.

Every aspect of the new CR pump has been tested to the limits – above and beyond what the pump will ever need to do in the field. Virtual simulation models have been validated by calculations and by physical prototype testing of components and complete pumps in our advanced test facilities.

A state-of-the-art product like the new CR pump requires a state-of-the-art production line. Designed to maximise quality, precision and speed, our dedicated CR production line moves the limits of performance, with burr-free laser cutting, automated laser welding and inline 3D tolerance scans.
