CR Series Vertical Multistage Pumps
The CR pump is built from cast iron with all wetted parts made of AISI 304 grade stainless steel, making this pump suitable for non-corrosive liquids. With world-class efficiency, flows up to 320 m3/h and 40 bar working pressure, the CR is the perfect virtical centrifugal pump for a range of demanding applications, such as liquid transfer, circulation and pressure boosting of cold or hot water, aqua-farming and field irrigation.
Tight controls over every aspect of the production process are the secret behind the reliability of the vertical centrifugal pump CR. Grundfos production is certified in accordance with the strictest international standards (ISO 9001) and is subjected to rigorous process control. Each CR pump is tested for performance, power consumption and static pressure before leaving the factory.
