What Is a River Sand Dredger?
A River Sand Dredger, also known as a Sand Dredger, Sand Pump Dredger, or Sand Suction Dredger, is a specialized dredging vessel designed to extract sand, gravel, slurry, and sediment from rivers, lakes, reservoirs, ports, and coastal areas.
The equipment uses a high-performance Dredge Pump to transport sand-water mixtures through discharge pipelines to designated stockpiles, barges, or reclamation sites. River sand dredgers are widely used in river sand mining, channel dredging, harbor maintenance, land reclamation, and mining operations.
As one of the leading Dredging Equipment Manufacturers in China, Taian OCEAN Pump provides complete sand dredging solutions for customers worldwide.

How Does a Sand Pump Dredger Work?
A Sand Pump Dredger operates by loosening underwater sand deposits using high-pressure water jets or a cutter head. The loosened material mixes with water to form slurry, which is then sucked into a heavy-duty dredge pump and transported through discharge pipelines.
Working process:
- Positioning the dredger
- Loosening the sand layer
- Forming sand slurry
- Suction by dredge pump
- Pipeline transportation
- Discharge to stockpile or reclamation area
This continuous operation significantly improves sand mining efficiency and productivity.
Core Equipment: Heavy Duty Dredge Pump
The Dredge Pump is the heart of every river sand dredger.
OCEAN Pump dredge pumps are manufactured with high chrome wear-resistant materials to ensure reliable operation under severe abrasive conditions.
High Wear Resistance
The wetted parts are manufactured from:
Cr26 High Chrome Alloy
Cr28 High Chrome Alloy
Cr30 High Chrome Alloy
Advantages:
Excellent abrasion resistance
Extended service life
Reduced maintenance costs
Lower operating expenses
Ideal for transporting river sand, sea sand, gravel, and mining slurry.
Large Solid Handling Capability
Our dredge pumps can handle:
River Sand
Sea Sand
Gravel
Pebbles
Mining Slurry
Tailings
Mud and Sediment
Large particle passages allow efficient handling of coarse materials.
Long Distance Sand Transportation
OCEAN Pump dredging systems can achieve discharge distances of:
500 meters
1000 meters
1500 meters
Over 2000 meters
For ultra-long distance projects, booster pump stations can be integrated into the system.
High Solid Concentration
Our sand dredging systems can transport slurry with solid concentrations up to:
50%
60%
Even higher under specific conditions
This greatly improves dredging efficiency and production output.
