The submersible sand dredging pump, also known as a submersible sand suction pump, is an effective solution for dredging operations. Here's an overview of its features and benefits:
Integrated Design: The electric sand dredger pump combines the electric motor and mechanical pump on the same axis, allowing it to operate submerged in various mediums such as sand, mud, and slurry.
Agitated Impeller: This pump is equipped with an agitated impeller at the bottom, in addition to the main impeller. The agitated impeller stirs the sediment, facilitating easier extraction of materials and enhancing the efficiency of the dredging process.
Durable Construction: The main impeller, agitated impeller, and other overflow components are made from chrome alloy, which is known for its wear-resistant and corrosion-resistant properties. This ensures the pump can withstand harsh conditions and have a longer lifespan.
Efficient Dredging: The combination of the main and agitated impellers allows for effective stirring and extraction of sediment, leading to quicker and more efficient dredging operations.
Geomembrane Protection: If the pond, lake, or pool you need to dredge is covered with a geomembrane, the electric sand dredger pump is an excellent choice. It is designed to operate without damaging the geomembrane, thus preserving the integrity of the underlying structure.
In addition to the electric sand dredger pump, the OCEAN DMD/DMS hydraulic dredge pump is another effective option for dredging tasks. This pump is driven by hydraulic power and can be used as an excavator attachment or installed on a dredger for separate use. It can handle harder solid layers with the addition of 1-3 cutters, making it versatile for various applications. The hydraulic system also offers advantages in deep water areas and has a lower failure rate compared to electric systems.
Both the electric sand dredger pump and the OCEAN DMD/DMS hydraulic dredge pump provide robust solutions for dredging applications, utilizing advanced technology to enhance performance while protecting sensitive environments.

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.
