NK Pumps

Grundfos NK/NKG pumps are used in water supply, industrial pressure boosting, industrial liquid transfer, HVAC (heating, ventilation and air-conditioning), irrigation and process industries.

Grundfos offers a virtually limitless range of long-coupled (NK) end-suction pumps. Their sturdiness and reliability make them ideal for use in demanding environments such as the following:

• District heating plants
• Heating systems for blocks of flats
• Air-conditioning systems
• Cooling systems
• Wash down systems
• Other industrial systems.

• • Optimized hydraulics in housing and impeller = unimpeded liquid flow
  • O-ring seal between pump housing and cover = no risk of leakage
  • Housing, impeller and wear ring in different materials = improved corrosion resistance, no sticking elements
  • Back pull-out design for easy dismantling for service
  • Pump is electro-coated to increase corrosion resistance
  • Available with IE1, IE2 and IE3  motors
  • PN 10/16 and 25 bar
  • Temperatures up to 180 °C
