Grundfos pumps: CR,CRI,CRN,CRT E

CR, CRI, CRN, CRT, CRE range are multistage and energy efficient centrifugal pumps with superior reliability, for capacity demands of up to 180 m3/h. The basic CR circulation pump range is available in four different materials: cast iron, two grades of corrosion-resistant stainless steel and all-titanium.

There are 13 flow sizes, capable of producing up to 50 bar of pressure, and with a variety of shaft  seals and rubber materials. The modular building system means you can choose a version to meet almost any pump requirement, handle diffcult liquids and the most demanding operating conditions.

Technical data  
Flow, Q max. 5-3000 m³/h
Head, H max. 5-120 m
Liquid temperature -5°C to 18°C
Operating pressure max. 16 bar


The pumps are suitable for liquid transfer in:

  • Process water systems
  • Sea water systems
  • Pumping of acids and alkalis
  • Ultra filtration systems
  • Reverse osmosis systems


  • Integrated frequency converter to allow multi-speed operation and deliver optimal pump performance
  • Non self priming
  • Temperature control with exposure to very high, low or fluctuating temperatures

Whatever the particular challenges of your installation, for example, limited space, earthquake risk, high altitude or certifcation issues; the CR range has all bases covered.
