Grundfos was the first pump manufacturer ever to create a vertical multistage in-line pump. Known as the CR pump, this innovative design has inspired followers all over the world. Even so, continuous development and innovation ensure that the Grundfos CR pumps remain unmatched. The CR Pump of today reflects the needs and requirements of customers worldwide. All development work at Grundfos is carried out with the end-users in mind. The new generation of Grundfos CR pumps features a full range of sizes and limitless scope. For combinations to suit your specific needs.
At Grundfos, innovation is about making things better. And we focus our effort where it matters: 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 vertical 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. A number of ATEX-approved CRN pumps are available, according to the locality, hazard and likelihood of a dangerous situation occurring. ATEX-approved pumps are for use in potentially explosive atmospheres. Explosive atmospheres consist of air and combustible matter such as gases, vapors, mist, or dusts in which the explosion spreads after ignition.
