The OCEAN DMD/DMS submersible dredge pump is an advanced vertical submersible pump specifically engineered for a wide range of dredging tasks. Its design and functionality make it an ideal choice for effectively transporting various underwater materials. Below are some of the notable features and benefits of this pump:
Versatile Mounting Options: This pump can be easily mounted on dredgers or simple floating pontoons, providing flexibility for different dredging configurations and environments.
Powerful Centrifugal Design: The pump operates as a robust centrifugal pump, which allows it to handle highly corrosive and abrasive slurries. This capability is crucial for effective sediment transport, especially in harsh conditions where other pumps may fail.
Agitator for Enhanced Performance: Located at the bottom of the pump, the agitator stirs the water, increasing the concentration of solids. This feature significantly aids in the efficient mixing and transportation of sediments, ensuring that the pump can operate at optimal efficiency.
Jetting Capability: The pump can be fitted with a welded water nozzle, which enables it to jet sand. This functionality enhances the pump's ability to dislodge and transport materials, making it more effective in various dredging scenarios.
Additional Agitators: For challenging conditions involving particularly hard or sticky solid layers, the pump can be equipped with two or three extra agitators. This addition improves work efficiency by facilitating better flow and movement of sediments.
Efficient Sediment Transport: The combination of the agitator and the powerful centrifugal design allows for the effective transport of underwater sand, slurry, sludge, gravel, and other sediments to designated locations, ensuring that dredging operations are completed swiftly and thoroughly.
Durability in Harsh Conditions: Designed to operate in some of the most challenging environments, the OCEAN DMD/DMS pump ensures reliability and longevity, even when dealing with abrasive materials. This durability reduces maintenance needs and extends the pump's operational life.
In conclusion, the OCEAN DMD/DMS submersible dredge pump stands out as a robust solution for dredging operations. Its versatility, efficiency, and durability make it an excellent choice for various applications in the field of sediment transport.

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.
