2.Basic Introduction

① ZG sand pump feature:

ZG series sand pumps are designed for handling sand and heavy abrasive slurries. They are designed with high hardness alloy materials and thickened overflow parts for excellent abrasion resistance. It is mainly used for continuous transportation of strongly abrasive materials whose particles are so large that they cannot be transported by general slurry pumps.

② ZN dredge pump feature:

ZN series dredge pumps are used in dredging process, usually used with dredger. The overflow parts are made of high chrome alloy, with the advantages of high head, large flow, high efficiency, good cavitation margin, etc. It is suitable for land reclamation, dredging, flood control, construction of new ports or expansion of existing ports.

As a professional manufacturer of large sand mining and dredging pumps, technology and design have been incorporated into the manufacturing to provide the best cost performance required.
