Fully meet the requirements of dredgers for mud pumps.

The dredging pump system is mainly composed of a pump head, a reduction box, a flexible coupling, a marine transmission and a monitoring system.

The impeller, front guard plate and rear guard plate of the mud pump over-current component are all made of strong anti-wear alloy cast iron. The hardness of the material is more than 58HRC. The pump body is made of wear-resistant alloy steel with excellent anti-wear and pressure.

The structure is simple, easy to disassemble and repair, reduce the workload, reduce staffing and improve economic efficiency.

At the same time, we can use different metal materials to meet the requirements of use according to the requirements of users and different media conditions.

Applicable working conditions:

It is suitable for dredging and bucket wheel type ship dredging conditions, and is widely used in dredging, dredging and dredging projects in rivers, lakes, docks and coastal areas.

Product efficiency and energy saving are significant. Strong suction capacity, deep digging and high dredging concentration.

Strong flow capacity, continuous pumping of gravel, clay and high plastic clay.

It has strong matching and can be equipped with diesel engine and generator.

Performance range:

Dischargerange: 100~850mm

Flowrange:180~1600m3/h

Head range: 20 ~ 90m
