The Dredge Sled plays a crucial role in the dredging industry, providing specialized equipment designed for diverse dredging applications.
Efficient pond dredging is crucial for maintaining the health and aesthetics of water bodies, and the Dredge Sled significantly contributes to this by providing a powerful and compact solution. It is an ideal choice for your next project, ensuring you have the best resources and tools for any scale of operation.
The Dredge Sled is powered by the EDDY Pump which is a heavy-duty industrial non-clog slurry pump designed for industrial pumping and dredging applications, including dredging ponds.
Depending on your project, The EDDY Dredge Sleds are sized to meet our client’s requirements. Powered by the high-performance and low-maintenance EDDY Pump, our dredging equipment usually achieves 30-70% solids and handles high viscosity, high abrasion, and low pH materials without wearing down the pump or constant need for maintenance.
How the Dredge Sled Works
The term slurry is widely used in industrial applications. Slurry widely varies depending on the size of the grain, aggregation, distribution, cohesiveness, pH levels, flow characteristics, sedimentation rates and the specific gravity of the material. The Dredge Sled has been deployed across remote mining sites in Australia for over 15 years to combat mine tailings. This rugged yet simple design uses commonly accessible parts to ensure maximum uptime and easy repairs. The main components include diesel-electric power station, floating barge attached to shore by a cable and winch system. The EDDY Pump is lowered into the lagoon and stabilized with a sled to begin dredging. Optional water jetting rings are available for maximum agitation when desired.
During the dredging process, the dredged material is carefully removed and transported through a pipeline to designated disposal sites to maintain the desired depth and ecological balance of the water body.
Pump & Dredging
Applications – Pond & Lagoon Dredging
Mine Tailing Transfer
Mineral tailing ponds generate significant amounts of hazardous solid and liquid mine waste such as: heavy metals, metalloids, radioactive waste, acidic water, and process chemicals. These wastes (tailings) accumulate at the bottom of containment ponds, causing several environmental hazards and reduced water volume.
Containment Pond Maintenance
Containment ponds protect surface water and streams from dirty wastewater. Containment ponds are frequently used for water quality improvement, flood protection, and groundwater recharge. Sediment, including silt, and sludge accumulate over time on the bottom, limiting water volume and creating environmental hazards. The dredge sled is a cost-efficient solution to desludge your settling tank.
Farm Pond Cleaning
A farm pond is used for irrigation, livestock feed, erosion control, or aquaculture. Over time within livestock farms, dense solid waste accumulates at the bottom while less dense materials float to the top, causing reduced water volume.
Lagoon Dredging
Lagoons are pond-like bodies of water that receive, store, and treat wastewater for a predetermined amount of time. Lagoon dredging is used when sediment buildup is accumulated over time. Neglecting to do lagoon dredging maintenance will cause excess muck and debris to float to the surface, creating a foul odor. When looking for lagoon dredging equipment, the dredge sled is an easy to operate and maneuver allowing you to easily deepen and restore its look and color.
Heavy Metal Recovery
Removing heavy metals within wastewater, such as copper, lead, zinc, silver, and other metals, is a challenge and often regarded as uneconomic. The dredge sled removes these harmful metals through physical agitation while retaining cost efficiency. Use a dredge sled to re-run target materials through your process plant to create an ROI with your Dredge Sled.
Wastewater Management
Proper wastewater management is essential to ensure optimal system functionality. It is vital to maintain proper sediment control and water depths, especially with digester tanks and settling tanks. Sediment buildup will reduce water volume and compromise the integrity of the wastewater system. Dredging is a necessary method to return the lake or pond to a functional and efficient system. Offshore dredging presents unique challenges due to harsh conditions, but the Dredge Sled is designed to handle these environments effectively, ensuring versatile and reliable operations.

Alternate Deployment Setup With Self-Priming Pump
EDDY pump offers multiple dredge sled pump deployment options, including using a standard submersible EDDY Pump or a Self-Prime Pump Trailer option.
Using a self-priming pump in conjunction with the Dredge Sled offers several advantages:
- Limits pump corrosion in harsh environments
- Less weight to float
- Easier pump serviceability
- Much safer for ponds with delicate liners
Dredge Project Consulting
- Easier to install and maintain, the horizontal slurry pump, a type of dredge pump, allows for quick access to pump components, making repair jobs straightforward. During repair jobs, pumps are completely disassembled for thorough inspection. All components are carefully inspected, and any parts not meeting standards are replaced. After reassembly, the pump is tested to ensure reliable performance. These steps help extend the service life of the hydraulic pump and maintain equipment reliability. EDDY Pump can also provide dredging project managers to oversee sediment projects and remediation projects, ensuring that all aspects of the dredging project are managed efficiently and in compliance with environmental regulations.
- Requires more room, due to its larger footprint compared to vertical
- Implementing best management practices and evaluating management alternatives are essential for effective material management in any dredging project.
Vertical Slurry Pump
-
Less smaller footprint, allowing the dredge pump to be implemented in hard to reach jobs
-
More versatile, can be cable hung straight down and inserted directly into medium to pump target material. The vertical slurry pump can also be used in mechanical dredging operations where minimal water addition is required.
-
The vertical slurry pump is typically situated within the excavator or dredging system so that it is optimally positioned for efficient material handling and performance.
-
More difficult to repair and tougher maintenance
