NBK(F) immersed multi-stage centrifugal pumps achieving “super high efficiency” by optimizing the hydraulic performance of impellers, guide vanes and other parts.

Pump uses a standard motor with couplings connecting the pump components. Because the pump can change its length by adding empty guide vanes, it can meet the requirements of various environments for pump installation depth. NBK is mainly used for the transportation of non-corrosive liquids, and NBKF is mainly used for the transportation of mildly corrosive liquids.
