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. The NB range of end suction pumps are commonly used in: District heating plants Heating systems for blocks of flats Air-conditioning systems Cooling systems Wash down systems Other industrial systems
The NB End Suction Range has the following features: 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
