Grundfos NB Water Supply, Pump

Overview
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.

Applications
Grundfos offers a virtually limitless range of close coupled (NB) end-suction pumps. Their sturdiness and reliability make them ideal for use in demanding environments such as the following:

•     District heating plants
•     Heating systems for blocks of flats
•     Air-conditioning systems
•     Cooling systems
•     Wash down systems
•     Other industrial systems.

Features and benefits

•     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.
