The Grundfos CR series is a vertical, multistage centrifugal pump with suction and discharge ports at the same level. The pump head and base are made of cast iron. Other wetted parts are made of stainless steel (EN 1.4301). The versatile CR series is suitable for pressure boosting applications, for example in industry or waterworks and in heat recovery systems in building services. Flow range 0-200 m3/h, pressure range 0-40bar.

The extensive range is highly versatile due to its modularity. The product family also includes CRN models made of 1.4408/AISI316, CRI models made of 1.4301/AISI304, and titanium CRT.

The range is available in a variety of shaft seal, rubber material and mains voltage options. The pump is also available with magnetic drive. The pump components can be optimised to meet specific requirements to withstand challenging fluids and extremely demanding conditions.

Product benefits:
- Long-lasting and reliable
- Very efficient
- Very suitable for hot liquids
- Easy to maintain
- Space-saving
- Suitable for slightly corrosive liquids
- Good corrosion resistance
- Low internal pressure losses
