Grundfos NBG/NBGE SuperVortex Impeller

The Grundfos NBG(E) SuperVortex impeller pumps are end suction, close-coupled, single-stage centrifugal pumps. They guarantee reliability in heavy-duty industrial applications and are built for moving large volumes of water and other liquids. The new vortex impeller design provides free passage for stringy objects, long fibres, and solids up to 25 mm. These stainless steel pumps are also suitable for wastewater with up to 5% dry matter content.

Design Advantages

  • SuperVortex impeller with little to no contact with pumped fluid, minimising jamming
  • Good at passing solids with sizes up to 25mm without clogging
  • Designed to pump liquid with high content of sand and heavy-duty industrial applications
  • Standard close-coupled pumps with flanges according to ISO 2858 (and MGE motor for NBGE pumps)
  • Loose flanges for easy installation and maintenance (available in DIN, ISO and ANSI)
  • Reduced life cycle costs
  • Full range in stainless steel
  • Dedicated shaft seal solutions to accommodate most liquids encountered in industrial applications
  • Close-coupled pumps with flanges according to ISO 2858 (and MGE motor for NBGE pumps)
  • Back pull-out design enabling easy service of the pump
  • Optimized hydraulics in housing and impeller, which provides unimpeded liquid flow
  • O-ring seal between pump housing and cover, which ensures no risk of leakage

PRINCIPLE OF OPERATION

Grundfos range of booster pumps are centrifugal type hence use the same working principle. Booster pumps boost water pressure and, in many cases, improves the flow rate. They rely upon one or more impellers to draw the pumped fluid into the intake of the pump, and to boost its pressure as the fluid passes through the impeller and the volute or diffuser casing. Some are single-stage, meaning that they have a single impeller. These are generally used in applications where the amount of additional pressure (head) that is required is not significant. There are also multi-stage configurations involving more than one impeller, which are used to deliver higher heads such as would be required to move water up to substantially higher elevations or through much longer pipelines.
