GRUNDFOS NK end-suction centrifugal pumps standardized EN 733, regulated and unregulated

Customisable NK end-suction power for demanding applications 

Grundfos NK end-suction long-coupled pumps are non-self-priming, single-stage, centrifugal volute pumps with axial-suction port, radial-discharge port and horizontal shaft. If you require a multi-purpose pump suitable for a variety of demanding applications, the NK/NKG ensures reliable and effective supply. 

The long-coupled pump design offers easy service because of the spacer coupling. The NK pump has main dimensions designed to the EN733 standard, and all Grundfos end-suction pumps are tested to ISO909906:2012 Acceptance Grade standards before leaving the factory.
