An excavator dredge pump attachment turns your excavator from a digging machine into a high-capacity pumping system. Sand, silt, mud, slurry—this attachment moves them all. It mounts directly to your excavator arm in place of the bucket, draws material from underwater or waterlogged ground, and pumps it through a discharge hose to wherever you need it.
The YG series excavator mounted dredge pumps offer nine models covering flow rates from 150 to 500 cubic meters per hour. Each model is matched to specific excavator tonnage ranges from 10 to 40 tons. With agitator-equipped designs and wear-resistant construction, these attachments handle the toughest dredging conditions. For operators looking for an excavator-mounted dredge pump that transforms their machine into a continuous pumping system, the YG series delivers proven performance.

6 Applications of Excavator Dredge Pump Attachment
- River, Lake, and Harbor Dredging: Waterways accumulate sediment that obstructs navigation and increases flood risk. An excavator dredge pump attachment removes silt and debris efficiently, restoring water depth and flow. The excavator positions the pump from the shoreline or a barge, while the pump transfers material through a discharge line to a disposal area.
- Mining and Tailings Management: Mining operations generate large volumes of slurry and tailings. A hydraulic dredging pump moves these materials from settling ponds to processing or disposal areas. The agitator breaks up settled solids, and the pump transfers the slurry through pipelines.
- Construction Site Preparation: Before laying foundations or installing pipelines, construction teams must clear sites of unstable soil or waterlogged materials. An excavator dredge pump attachment dewaters excavation sites and removes saturated material, preparing the ground for construction.
- Pond and Lagoon Cleaning: Industrial ponds, agricultural lagoons, and wastewater treatment basins accumulate sludge over time. The pump attachment cleans these basins without draining them, reducing downtime and maintaining operations.
- Environmental Remediation: Contaminated sediments in industrial sites or polluted water bodies require safe removal. Dredge pumps extract the material for treatment or disposal. The precise positioning of the excavator allows targeted removal of contaminated zones while leaving clean material undisturbed.
- Marina and Port Maintenance: Marinas and ports require regular dredging to maintain depth for vessels. An excavator dredge pump attachment works in confined spaces where larger dredging equipment cannot operate.
What Materials Can the Excavator Mounted Dredge Pumps Handle?
The YG series is designed for high-solids handling. It moves materials that standard pumps cannot.
- Sand and Silt: The pump moves fine materials efficiently. The agitator keeps sand suspended in the slurry, preventing settling in the pump or hose.
- Gravel and Small Rocks: The pump bypasses hard objects that exceed the particle size limit, preventing damage to the impeller. The wear-resistant components handle abrasive gravel without excessive wear.
- Mud and Clay: The agitator breaks up compacted mud and clay at the intake. The pump moves the loosened material through the discharge hose.
- Slurry: The pump handles water-saturated materials with high solids content. The agitator maintains suspension, and the pump moves the slurry at consistent flow rates.
- Debris: The agitator blades cut through small debris. For larger objects, the pump bypasses them to prevent damage.
6 Advantages of an Excavator Dredge Pump Attachment
1. Continuous Operation, No Stopping
An excavator bucket works in cycles: dig, lift, swing, dump, return. Each movement takes time, and material stops moving between cycles. A dredge pump works continuously. As long as the excavator is running, the pump keeps moving material through the discharge line. For large-volume jobs, this continuous flow completes the work in a fraction of the time.
2. Works Where Buckets Cannot
Underwater digging with a bucket is inefficient. Material falls through the teeth during lifting, and water washes away fine particles before they reach the surface. A dredge pump works directly underwater, drawing material and water together through the intake. What the bucket would lose, the pump captures and delivers through the hose.
3. Handles High Solids Content Without Clogging
Sand-laden water, thick mud, and slurry with debris are difficult for standard pumps. They clog easily and wear out quickly. Dredge pumps are designed for high-solids handling, with wide-flow channels and wear-resistant casings that allow particles up to 20- 60 mm to pass through. The YG series handles solids content from 40% to 70% without clogging.
4. Powered by the Excavator’s Own Hydraulics
No generator, no external power source, no extra fuel tank. The pump runs directly from the excavator’s auxiliary hydraulic circuit. One machine arrives on site and does the job. For remote locations and sites without reliable electricity, this self-contained power system is a practical advantage.
5. Quick Attachment Change, Multi-Purpose Machine
The pump connects through the same quick coupler system as a standard bucket. Switching takes minutes. The same excavator digs trenches in the morning, pumps slurry in the afternoon, and returns to bucket work the next day. No second machine is needed, no extra transport, no additional capital investment.
6. Precise Positioning
The pump sits at the end of the excavator arm. The operator places it exactly where needed—into a corner of a pond, against a sloped bank, or at the bottom of a deep trench. This precision allows targeted removal of sediment without disturbing surrounding areas.
