Grundfos' multi-stage CR pump range features a maximum flow of nearly 800 gpm

Grundfos now offers the multi-stage CR pump in a “super-sized” capacity with a maximum flow of nearly 800 gpm. The CR is available in 13 hydraulic sizes, four basic materials and over one million configurations. The CR’s features ensure reliability via dry running protection and a cartridge seal design that prevents wear and enables rapid replacement in under an hour.

The narrow interval between CR pump sizes provides minimized difference in pump capacity, required pressure and volume, resulting in a pump that runs as close to its optimum duty point as possible. This translates into a power reduction of 15-20%.
