Grundfos NB
Single-Stage
End-Suction Standard Pumps

Grundfos NB
Grundfos NBG
Grundfos NBE
Grundfos NBGE

The Grundfos NB family are multi-purpose end-suction pumps for reliable and
cost-efficient applications such as water supply.

Non-self priming, single-stage, centrifugal volute pumps with axial suction port,
radial discharge port and horizontal shaft; these close-coupled pumps are following the same inlet
and outlet dimensions as mentioned in EN733 (For NB) and ISO2858 (for NBG),
that are normally used for long coupled pumps.

Grundfos standard and block pumps are highly versatile pumps, suitable for a wide range
of applications that require reliable and efficient supply.

Grundfos NB family standard and block pumps are mainly used in five application areas:
 

  • ✔︎ Water supply
  • ✔︎ Industrial pressure increase
  • ✔︎ Industrial liquid transport
  • ✔︎ Indoor climate (heating, ventilation and air conditioning)
  • ✔︎ Irrigation

Benefits

  • Optimised hydraulics in housing and impeller for unimpeded liquid flow
  • O-ring seal between pump housing and cover means no risk of leakage
  • Housing, impeller and wear ring in different materials for improved corrosion resistance, no sticking elements
  • Easy Maintenance
