The Grundfos CR vertical, multistage, centrifugal in-line pump family works for water supply, water treatment and almost any industrial solution – including those for high-pressure, hot, dangerous, flammable and aggressive liquids.

The CR is available in millions of different configurations through four modules: 

• Motors
• Shaft seals
• Pump modules
• Connections.

Offering a “mix and match” modular approach, so you can configure a pump that meets your exact needs. Grundfos test, qualify and document all modules.

The basic CR pump range is available in four different materials: cast iron, two grades of stainless steel and titanium. Thirteen flow sizes are capable of producing up to 180 m³/h at 50 bar, with a variety of shaft seals, rubber materials and supply voltages.

Optimising pump parts that are typically vulnerable to difficult liquids or demanding operating conditions.

Grundfos also offer highly efficient “E” version pumps with a built-in frequency converter or pumps with an external frequency converter (CUE). These combine the very best of pump technology with highly efficient motors and variable speed drives. You will never use more energy than you need.
