Grundfos NK/NKG pumps are used in water supply, industrial pressure boosting, industrial liquid transfer, HVAC (heating, ventilation and air-conditioning), irrigation and process industries.
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 (heating, ventilation and air-conditioning), and irrigation.
The pumps are all non-self-priming, single-stage, centrifugal volute pumps with axial suction port, radial discharge port and horizontal shaft. The Grundfos NK/NKG range comprises a complete series of long-coupled pumps that comply fully with either EN733 or ISO2858. The pumps are of the back pull-out design, enabling removal of the motor, coupling, bearing bracket and impeller without disturbing the pump housing or pipework. Even the largest pumps can thus be serviced by one person with a crane. The ISO2858 range of pumps are available with a bearing life of 100,000 hours, and can be fitted with double seals. They available in a stainless steel version as an option.
Grundfos offers a virtually limitless range of long-coupled (NK) 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.
