For engineers who like to move the limits

The new generation Grundfos CR pumps are designed of world-class efficiency and reliability - with millions of customisable solutions.

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 pumps have been designed using state-of-the-art simulation-driven processes and have been field-tested around the world – so you can install and operate the range with total confidence.

New CR production line moves the limits

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.

Discover how the new CR is made and performance-tested in this video.

Hydraulic efficiency

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.

Watch the video for an overview of the hydraulic design improvements.

Tested to the limits

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. Every single CR pump leaving a Grundfos factory is performance-tested and approved according to ISO 9906:2012 before shipping. ​
