Grundfos CR Vertical Multistage Pumps

  • Reliability
  • High efficiency
  • Service-friendly
  • Space-saving
  • Suitable for slightly aggressive liquids
  • High corrosion resistance

The basic CR pump range, which can be applied in almost any industrial solution, is already in itself the broadest range available. Through our modular approach, we have made it even broader.

The basic CR pump range is available in four different materials: cast iron, two grades of stainless steel, and all-titanium. There are eleven flow sizes, capable of producing up to almost 50 bar of pressure, and with a variety of shaft seals, rubber materials and supply voltages.

Pump parts which are typically vulnerable to difficult liquids or particularly demanding operating conditions can be optimised for their purpose and designed for specific requirements.

CR pumps provide a complete range of pump solutions so that all applications, industrial and domestic, can benefit from the Grundfos touch.

The applications that can be covered include the following:

  • Process water systems
  • Washing and cleaning systems
  • Seawater systems
  • Pumping of acids and alkalis
  • Ultrafiltration systems
  • Reverse osmosis systems
  • Swimming pools
