The Submersible Dredge Pump, also known simply as a submersible dredge pump, features an electric motor and mechanical pump aligned on the same axis. This design allows it to be submerged in various mediums to efficiently dredge sand, mud, slurry, and more. Our technical team has incorporated advanced foreign technology, including an agitated impeller installed at the bottom of the pump in addition to the main impeller. This agitated impeller stirs the sediment, enabling the Submersible Dredge Pump to extract materials easily, which ensures that dredging tasks are completed efficiently and thoroughly. The main impeller, agitated impeller, and other components in contact with the fluid are constructed from chrome alloy, providing excellent wear resistance and corrosion resistance. If the pond, lake, or pool you need to dredge is lined with a geomembrane, the Submersible Dredge Pump is an ideal choice, as it is designed to prevent damage to the geomembrane during operation.

1. The Submersible Dredge Pump has better stability and longer life span because the main parts are made of abrasion-resistant materials - chromium alloy.
2. A unique mechanical seal device can prevent the electric motor from high-pressure water and impurities, then high suction efficiency can be ensured.
3. Except for the main impeller inner pump, there is extra agitation impeller at the bottom to cut and mix the sludge, so the efficiency will be improved more.
4. The Submersible Dredge Pump is easy to install and operates while without an additional vacuum pump or pump house.
5. The Submersible Dredge Pump is high efficient and early-saving due to the powerful bottom agitator.
6. Professional technology support is provided for the whole process of usage and maintenance.
1. The Submersible Dredge Pump is suitable for conveying liquid with slurry, solid particles of gravel, cinders, and tailing, etc.
2. The Submersible Dredge Pump is widely used in river dredging, sand pumping vessel, sewage treatment plants, metallurgical industry, mining, power plants, etc.

1. Are your pumps and spares interchangeable with other brands?
Yes. 100% interchangeable, whatever the material, working life and working efficiency.
2. What price of your pump and spares?
Our price is 30~50% of the original but the same working life.
3. What is your lead time?
Some popular spares are in stock which could deliver within 5 days after your PO. If without stock, we could deliver within 3 weeks.
4. What is your warranty?
One year for the whole pump except the wear parts. The working life of wet parts is the same as the most famous brand.
5. Do you have an OEM service?
Yes. We offer OEM service to our clients. And our engineers could train the users on-site how to start, use and maintain the pumps.
