Grundfos CRI Vertical In-Line Multistage Pumps

Grundfos CRI Vertical In-Line Multistage Pumps for Pressure Boosting, Water Treatment, HVAC, and Industrial Process Systems

Grundfos CRI Vertical In-Line Multistage Pumps are stainless steel centrifugal pumps designed for applications requiring reliable pressure generation, efficient operation, and enhanced corrosion resistance. Built on the proven Grundfos CR multistage platform, CRI pumps are well suited for pressure boosting, water treatment, industrial process water, HVAC, glycol circulation, washing, cooling, and general water supply applications.

The Grundfos CRI is a vertical multistage centrifugal pump with an in-line configuration. Multiple impeller stages allow the pump to generate substantial head while maintaining a compact footprint, making the CRI particularly useful in mechanical rooms, process systems, equipment skids, and industrial installations where both high pressure and efficient use of floor space are important.

A key distinction of the CRI range is its AISI 304 stainless steel wetted construction. Grundfos specifies AISI 304 stainless steel for all CRI components in contact with the pumped liquid, providing good corrosion resistance across a broad range of water applications. This makes CRI pumps a strong choice for water and slightly aggressive compatible liquids where a higher level of corrosion resistance is desired compared with standard cast-iron-based pump construction.

The CRI range is designed for applications including liquid transfer, glycol circulation, pressure boosting, and circulation of cold or hot water. Its combination of stainless steel construction and multistage hydraulics makes the pump versatile enough for commercial building systems as well as demanding industrial processes.
