New CR pushes the boundaries

For engineers who like to move the limits

The new Grundfos CR is for engineers who like to push the boundaries 

Meet the new generation of Grundfos CR pumps – the more efficient and 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. And despite a smaller footprint, 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.

How to achieve 30% energy savings

How to achieve up to 30% energy savings

An Austrian water utility company were amazed by the performance data of their new CR pumps after just 6 months of operation.

Testing the new generation of CR pumps in the field has already made a big impact. Find out what three CR95 pumps achieved after 14 months of operation in a Danish district heating plant.

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.

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.

New CR production line 

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.
