Grundfos NK Pumps

Please be advised that the Grundfos LF series long-coupled pumps have been officially discontinued. The recommended upgrade path is the modern Grundfos NK series long-coupled pump.

Grundfos NK series pumps offers superior efficiency and updated hydraulics, it is important to note that the NK series is not a direct drop-in replacement. If you are transitioning an existing installation from an LF to an NK pump, your field installation teams must prepare.
