ZN dredge pumps are new type of single-stage, single suction, cantilever horizontal dredge pumps. with advantages of high efficiency, wear resistant, excellent performance, they were 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.


1. Cantilevered, horizontal, centrifugal, one stage, single casing pump;

2. High head, large capacity, high efficiency, good NPSH performance;

3. Long bearing life, the bearing assembly with large diameter shaft and short overhang;

4. Wear-resistant wet parts, the wet parts are made of Ni hard and high chromium abrasion resistant alloys. (more than 27% Chrome alloy);

5. The shaft seals can be gland seal or Lip seal;

6. The discharge branch can be positioned at interval of 45 degrees by request and oriented to any eight positions to suit installations and applications.
