Dredge pumps are widely used in river dredging, dredging and sand absorption and other engineering industries, and mud wear and cavitation are two of the most common reasons for the decline in performance and shortened service life of dredge pumps.

This phenomenon leads to performance problems with the pump on the one hand, and on the other hand can damage pump parts (impellers, volute etc.) and even damage the pump foundation and piping system. Replacing defective parts not only increases maintenance costs, but also increases downtime and production losses. So choosing the right pump parts is crucial to the product and production.

Zidong Pump’s ZN550 dredge pump impeller, in the fastest wear position redesigned raised wear ring, improve the service life and wear resistance; blade from the original ZN450 5-blade based on the upgrade to 4-blade, large flow, through the particles.

The parts in contact with the slurry are made of wear-resistant high chrome alloy material with Cr 26-28% and HRC60+ hardness, which is able to withstand severe wear in an abrasive environment and has long anti-wear life characteristics that are superior to other metal materials.

Depending on the site conditions, customers can replace and choose other materials to make the pump provide maximum efficiency with minimal maintenance requirements.
