Grundfos NB, NBG, NBE, NBGE & NK End Suction Centrifugal Pumps

Grundfos offers a virtually limitless range of close coupled (NB) end-suction pumps. Their sturdiness and reliability make them ideal for use in demanding environments.

Grundfos end-suction pumps are used in water supply, industrial pressure boosting, industrial liquid transfer, HVAC (heating, ventilation and air-conditioning), and irrigation.

Grundfos end-suction pumps are multi-purpose pumps suitable for a variety of different applications requiring reliable and cost-efficient supply. End-suction pumps are used in five main areas of application: water supply, industrial pressure boosting, industrial liquid transfer, HVAC and irrigation.

The Grundfos NB/NBG pumps are all non-self-priming, single-stage, centrifugal volute pumps with axial suction port, radial discharge port and horizontal shaft. The NB/NBG range consists of close-coupled pumps with their main dimensions in accordance with either EN733 or ISO2858.

The NB range of end suction pumps are commonly used in:

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

Full operation and specification details can be found under the “Additional Information” tab.
