In the coastal region of Kuwait, a marine construction and dredging contractor was facing a persistent challenge. The country’s shallow harbor channels and coastal waterways were experiencing rapid siltation. Sand and sediment accumulated faster than traditional dredging methods could remove them. The contractor had been using suction dredgers and barge‑mounted pumps, but these required substantial mobilization time and could not reach the shallowest areas near the shoreline. With port operators demanding deeper channels for larger vessels, the contractor needed a more agile and efficient solution.
The project manager discovered an excavator dredge attachment from YG Machinery—specifically the YG500-15 model designed for 20‑30 ton excavators. This hydraulic high-speed slurry pump mounts directly on the excavator arm, is powered by the machine’s hydraulic system, and features a built-in agitator with stirring teeth to loosen compacted sediment. The unit delivers a 500 m³/h flow at 15 meters of lift, making it ideal for harbor maintenance and channel clearing.
The difference was immediate. The Kuwaiti crew now positions the excavator at the water’s edge, lowers the excavator’s hydraulic sand pump into the sediment, and pumps slurry directly to a disposal site. The unit reaches shallow areas that larger dredgers cannot access. The contractor completed the harbor clearing project in half the expected time.

Technical Parameters Of The Excavator Dredge Attachment
Below are the specifications for the YG series excavator‑mounted slurry pumps. The Kuwaiti contractor chose the YG500-15 model.
| Serial No. | Model | Flow m3/h | Lift(m) | Matching Agitator | Stirrer Torque | Excavator Tonnage |
| 1 | YG200-15 | 200 | 15 | 5.5KW | 1556 | 10T-20T |
| 2 | YG150-30 | 150 | 30 | |||
| 3 | YG300-20 | 300 | 20 | |||
| 4 | YG400-10 | 400 | 10 | 7.5KW | 1946 | 20T-30T |
| 5 | YG500-15 | 500 | 15 | |||
| 6 | YG250-35 | 250 | 35 | |||
| 7 | YG300-30 | 300 | 30 | 15KW | 2433 | 30T-40T |
| 8 | YG400-30 | 400 | 30 | |||
| 9 | YG400-40 | 400 | 40 |
Why the YG500-15 suited the Kuwaiti marine contractor:
- 500 m³/h flow rate – moved large volumes of sediment quickly, meeting the project’s tight deadlines.
- 15m lift – sufficient to pump slurry from the harbor bottom to the disposal area onshore.
- 7.5KW agitator with 1946 N.m torque loosened compacted sand and silt effectively.
- 20‑30T excavator compatibility – matched the contractor’s existing fleet, eliminating the need for new equipment.
- Hydraulic drive eliminated the need for electrical power, crucial for remote coastal sites.
Three Challenges That Made Harbor Dredging Difficult In Kuwait
The Kuwaiti contractor faced three problems common across the Gulf region’s marine construction sector.
Problem 1: Rapid Siltation In Shallow Waters
Kuwait’s coastal waters experience significant sediment deposition. Fine sand and silt accumulate quickly, reducing channel depths and restricting vessel access. Traditional dredging methods require large, expensive equipment that cannot operate in shallow nearshore areas.
Problem 2: Limited Access For Large Dredgers
Suction dredgers and cutter suction dredgers are massive and require deep water to operate. They cannot reach the shallows near shorelines, breakwaters, or small harbors. The contractor needed equipment that could work in water depths as low as one meter.
Problem 3: High Mobilization Costs
Mobilizing a large dredger to a site takes days and costs thousands of dollars per day. For small to medium dredging projects, the mobilization cost alone could exceed the project budget. The contractor needed a solution that could deploy quickly and cost‑effectively.
The excavator dredge attachment solved all three.
How Did The Hydraulic High Speed Slurry Pump Transform The Kuwaiti Project?
The excavator hydraulic sand pump is a centrifugal pump powered by the excavator’s hydraulic system. A hydraulic motor drives the impeller, while an agitator at the pump intake loosens compacted sediment. The pump draws in a slurry of water and solids, then discharges it through a pipeline to a disposal area. The entire unit mounts on the excavator arm via a quick‑attach plate.
Reaches Shallow Waters
The excavator positions the pump directly into the sediment. The unit operates in water as shallow as one meter—far shallower than any large dredger can reach. The Kuwaiti crew cleared sediment from harbor edges, marina basins, and channel entrances that had been inaccessible for years.
High Solids Concentration
The agitator, combined with optional side cutters or mixing augers, breaks up compacted material and mixes it with water to form a pumpable slurry. The excavator hydraulic sand pump handles solids concentrations up to 70%—far higher than conventional centrifugal pumps. The Kuwaiti contractor reported pumping sand‑water mixtures that would clog standard pumps.
No Power Supply Needed
Because the unit is powered by the excavator’s hydraulic system, no external electrical supply is required. This is a major advantage in remote coastal areas where grid power is unavailable. The excavator’s diesel engine provides all the energy needed.
Rapid Deployment
The excavator dredge attachment installs in minutes—simply remove the bucket and attach the pump. The contractor moves from site to site without the costly and time‑consuming mobilization required for large dredgers.
Real Feedback From The Kuwaiti Marine Contractor
After three months of using the YG500-15 excavator dredge attachment, the project manager shared his results.
- Dredging speed: The unit pumped over 500 m³ of slurry per hour, clearing sediment three times faster than the contractor’s previous methods.
- Access: The excavator reached areas where large dredgers could not operate, including marina basins and harbor edges.
- Solids handling: The pump handled sand‑water mixtures with over 60% solids content without clogging.
- Mobilization: The unit deployed from the yard to the job site in under two hours, compared to three days for a large dredger.
- Payback: The excavator hydraulic sand pump paid for itself within three months through reduced mobilization costs and faster project completion.
The project manager said: “Kuwait’s harbors silt up fast. We were constantly fighting to keep channels open. The YG500-15 excavator dredge attachment changed our approach entirely. We can clear sediment anywhere the excavator can reach—including places we never thought possible. The pump handles thick sand slurry without clogging. It’s the most cost‑effective dredging tool we have ever used.”
An operator added: “The hydraulic high-speed slurry pump is straightforward. I attach it to the arm, lower it into the water, and start pumping. The agitator breaks up the compacted sand, and the pump moves it all. I can operate it from the cab without getting wet or dirty. The best part is we don’t need a support vessel—just the excavator and a pipeline.”
