CR
The Grundfos CR vertical, multistage, centrifugal in-line pump family works for water supply, water treatment and almost any industrial solution – including those for high-pressure, hot, dangerous, flammable and aggressive liquids.
Now, the range has been upgraded with a new, more robust generation of CR pumps (CR 95, CR 125 and CR 155), offering an optimised hydraulic design for world-class energy efficiency.Thanks to a small footprint, the pumps are also easier and less costly to install than comparable pumps. The new CR pumps have been developed using simulation-driven design to perfect every single component and have been field-tested around the world, so you can install and operate the range with total confidence.For more information on the new generation of CR pumps, download the leaflet under ‘Brochures’ in the menu or click here.
The CR is available in millions of different configurations through four modules:
- Motors
- Shaft seals
- Pump modules
- Connections
We offer a “mix and match” modular approach. In Grundfos Product Center(GPC) we offer a large variety of CR pumps. Further, you can utilise the configurator to customize the solution to your specific application. We offer a “mix and match” modular approach, so you can configure a pump that meets your exact needs. We test, qualify and document all modules, just like we do for any standard Grundfos pump.
The basic CR pump range is available in four different materials: cast iron, two grades of stainless steel and titanium. Thirteen flow sizes are capable of producing up to 180 m3/h at 50 bar, with a variety of shaft seals, rubber materials and supply voltages.
We optimise pump parts that are typically vulnerable to difficult liquids or demanding operating conditions.
We also offer highly efficient “E” version pumps with a built-in frequency converter (CRE) or pumps with an external frequency converter (CUE). These combine the very best of pump technology with highly efficient motors and variable speed drives. You will never use more energy than you need.
