NK


Portable Dewatering Pumps

Discharge Bore(mm) 50 ・ 80
Motor Output(kW) 1.5 ・ 2.2

The NK-series is a submersible single-phase portable drainage pump having a larger output motor. Though it is a single-phase unit, the pump has the durability equivalent to three-phase drainage pumps, since the wear parts are made of abrasion-resistant materials. 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.
