The NK-series is a submersible single-phase portable drainage pump equipped with a massive output motor of 2.2kW. It is the largest single phase motor available in the Tsurumi protfolio providing all the benefits of a 3phase pump with the advantage of connecting to a 230V power supply. The top discharge, side flow design assures efficient motor cooling even when it operates with its motor exposed to air.The slim design allows the pump to be placed in a confined space.
