NB, NBG, NBE, NBGE end-suction close-coupled pumps

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

General Details

Overview

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.

Applications

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 such as the following:

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

Features and benefits

  • Optimised 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
  • Pump is CED coated to increase corrosion resistance
  • Available with IE1, IE2 and IE3 motors
  • Available in a number of shaft seal and material variants
  • PN 10,16 and 25 bar
  • For temperatures up to 140 °C.
