For engineers who like to move the limits

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


The CR 255 pump completes the CR range and continues to move the limits

The impressive new CR 255 is now available, completing the CR range and continuing to move limits with a flow range up to 320m3/h. 

After the last big addition of the CR 185 and CR 215 pumps – with a flow range capacity up to 240 m3/h and 280m3/h respectively – we continue to push the boundaries with this strong addition to the world’s most modular pump range. Our new hydraulic design 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. 

Our CR range delivers world-class reliability, with pumps that are tested to the absolute limits and beyond to offer optimised operating economy via enhanced hydraulic efficiency. The CR pump range provides literally millions of solutions to fit your every application need.

The CR 255, CR 215 and CR 185 are three new CR pumps that together with the CR range continue to push the boundaries of performance. Find out more below and get a first-hand look at the added value of the new flow range capacities brought to you by the CR 255, CR 215 and CR 185. 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.

A tradition of excellence: follow the CR through five decades

It all started with a request from a customer in 1971. That was when Grundfos invented the vertical, multistage, centrifugal in-line pump concept. Watch our film about the development of the CR pump through five decades, told by the Grundfos specialists who were there at each step of the journey.

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. ​
