Grundfos end-suction pumps (NB/NBG)

Grundfos end-suction pumps are multi-purpose pumps suitable for a variety of different applications demanding reliable and cost-efficient supply.

End-suction pumps are used in five main fields of applications: Water supply, industrial pressure boosting, industrial liquid transfer, HVAC (heating, ventilation and air-conditioning), and irrigation.

The NB pump lives up to the EN733 standard and the NBG pumps lives up to the ISO2858 standard. The NB/NBG range is a close-coupled pump and covers a flow up to 1000 m3/h and 200 kW.

The main difference between a NK/NKG and a NB/NBG pump is that the NB/NBG is small and compact and thereby space saving. On the other hand, the NK/NKG end-suction pumps are easier to service due to the possibility of a spacer coupling.

Main product characteristics
