The new generation of large vertical Grundfos CR pumps has a number of features which make them stand out from their predecessors. In particular, pump design has been completely updated resulting in the increased efficiency. The unique thrust handling device (THD) reduces the resulting axial force the motor bearings must absorb. This allowed to provide longer lifetime to the motor bearings.
Another peculiarity of the new range refers to high head models providing a pressure of up to 40 bar. Besides, the pumps can operate at different voltages.
CR pumps are widely used in industry. They are installed in process-water systems, ultra-filtration systems, in swimming baths, and used for acids and alkalis transfer. The pumps are suitable for slightly aggressive liquids and have high corrosion resistance.
The key advantages of CR are energy efficiency, ease of maintenance, compact design, the ability to generate high pressure with just one device.
