ZN series adopts large inlet design in order to produce more pressure on the impeller and increase output and efficiency. ZN dredging pump mostly has 5 vanes closed impeller, which has a more stable structure and higher efficiency compared with 3 vanes impeller.
Overview
ZN Dredge Pump is new type of single-stage, single suction, cantilever horizontal dredge pump.
It is composed of a pump head, reducer gear box, high elastic coupling, and marine transmission monitoring system.
With advantages of high efficiency, wear resistant, excellent performance,
It is designed for handling more abrasive with solids slurries in the river dredging, sand reclamation,
explosive sludge in metal melting, dredging in dredger and course of river and other fields.
