DESCRIPTION
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.
