The OCEAN DMD/DMS submersible dredge pump is a highly efficient vertical submersible pump designed for various dredging applications. Here are some of its key features and benefits:
Versatile Mounting Options: The pump can be mounted on dredgers or simple floating pontoons, making it adaptable for different dredging setups.
Powerful Centrifugal Design: It operates as a powerful centrifugal pump, capable of handling highly corrosive and abrasive slurries, which is essential for effective sediment transport in harsh conditions.
Agitator for Enhanced Performance: At the bottom of the pump, there is an agitator that stirs the water to increase the solid concentration. This feature helps in efficiently mixing and transporting sediments.
Jetting Capability: The pump can be equipped with a welded water nozzle to jet sand, enhancing its ability to dislodge and transport materials.
Additional Agitators: For particularly hard or sticky solid layers, the pump can be fitted with two or three extra agitators, which improves work efficiency by facilitating better sediment flow.
Efficient Sediment Transport: The combination of the agitator and the powerful centrifugal design allows for effective transport of underwater sand, slurry, sludge, gravel, and other sediments to specified locations.
Durability in Harsh Conditions: The pump is designed to operate in the most challenging environments, ensuring reliability and longevity even when handling abrasive materials.
In summary, the OCEAN DMD/DMS submersible dredge pump is a robust solution for dredging operations, offering versatility, efficiency, and durability.

1.The Electric Sand Dredger Pump is suitable for conveying liquid with slurry, solid particles of gravel, cinders and tailing, etc.
2.The Electric Sand Dredger Pump is widely used in river dredging, sand pumping vessel, sewage treatment plants, metallurgical industry, mining, power plants, etc.
Our customer from Yangzhou signed a bridge pile sinking project. He needed to extract the sand thoroughly from the caisson.He wanted to order a Electric Sand Dredger Pump to carry out this project. The hydraulic Electric Sand Dredger Pump should has the characteristics of easy operation, high extracting efficiency and competitive price. Meanwhile his construction period was short, the customer required a short supply cycle. He hoped that the Electric Sand Dredger Pump could arrive the construction site in two days after signed contract with us.
According to the customer's requirement and the similar working condition, our technical team recommended Electric Sand Dredger Pump to the customer. The Electric Sand Dredger Pump equipped with a set of agitated impeller at the bottom of pump body, the agitated impeller can stir the mud, so the Electric Sand Dredger Pump could extract sand thoroughly and improve work efficiency. The over-flow parts of the Electric Sand Dredger Pump were made of corrosion resistant and wear resistant material, so the life span was long.
