  • Crystallising liquids: Glycol additives, naphthalene, sugar products, salts
  • High pressures: Water treatment, cleaning / washing
  • Extreme temperatures: Oils, boiler feed, secondary coolants

Grundfos motor: Grundfos make their own motors to ensure maximum performance. The MG motors are silent and efficient. They are also available in the self-regulating MGE configuration, featuring an integrated frequency converter.

Cartridge seal: The specially designed cartridge seal increases reliability, ensures safe handling and enables easy service and access.

Shaft seal solutions: The cartridge seal configuration comes in a wide choice of materials. It is available in flushed seal, double seal and magnetic drive and handles temperatures from -40ºC to 180ºC.

Improved efficiency: By minimising the difference between pump capacity and the required pressure and volume, users can get a pump, which runs as close to optimum duty point as possible.

Connection options: The Grundfos CR centrifugal pump can be connected to any system.

Dry-running sensor: The patented Grundfos LiqTec system eliminates the risk of breakdowns due to dry running. If there is a no liquid in the pump, the LiqTec will immediately stop it.

Material options: The CR centrifugal pump is available in four different materials: titanium, stainless steel AISI 316, stainless steel AISI 304 and AISI 304 /cast iron.
