Grundfos CR is used where a vertical multistage pump is required to generate head in water and compatible industrial-liquid duties. Typical uses include transfer, circulation, pressure boosting, water treatment, irrigation and utility systems. For engineers and maintenance teams, correct selection matters because the hydraulic duty, liquid compatibility and pressure class directly affect process continuity and service life.
Grundfos describes CR as a non-self-priming vertical multistage centrifugal pump. The pump consists of a base, pump head and chamber stack, with inlet and outlet ports on the same level in an in-line arrangement. Grundfos documentation also describes a cartridge-type mechanical shaft seal and stainless-steel hydraulic parts, while the standard CR pump head and base are cast iron.
AxFlow publishes CR performance data up to 336 m³/h, differential pressure up to 40 bar, head up to 362 m and liquid temperatures from -30 to 120 °C. These are series-level limits, not a universal operating point. The selected size, seal, materials and motor must therefore be checked against the actual liquid, system curve and site conditions.
The multistage in-line construction supports a compact plant layout, while the cartridge shaft seal and modular pump stack provide defined service points. Correctly matching the pump to the duty helps avoid operation away from the intended range, unnecessary wear and premature component replacement. AxFlow can support selection, service planning and spare-parts identification to help control downtime and lifecycle cost.
