Industries Served
Mining and Tailings Transfer
Submersible slurry pumps are widely used in mining operations for transferring tailings, thickened slurry, settling pond material, and abrasive solids generated during mineral processing. Their ability to handle high solids concentrations and coarse particles makes them suitable for continuous operation in harsh slurry environments where conventional pumps often experience rapid wear or clogging.
Dredging and Sediment Removal
These pumps support dredging operations involving sediment removal, lagoon cleanup, pond maintenance, canal dredging, and industrial slurry excavation. Fully submersible deployment allows operators to position the pump directly within the material, improving solids capture efficiency while reducing suction-related limitations during high-solids dredging operations.
Wastewater and Sludge Handling
Municipal and industrial wastewater facilities use submersible slurry pumps for transferring sludge, grit, biosolids, clarifier sediment, and high-solids waste streams. Their non-clog design helps maintain stable flow when handling viscous sludge and debris-laden material commonly found in wastewater treatment environments.
Oil, Gas, and Industrial Waste Transfer
Oil and gas facilities use submersible slurry pumps for drilling mud transfer, tank cleaning, sump cleanup, and industrial waste handling applications. The pumps are commonly deployed in confined or hazardous operating areas where submerged pumping improves operational flexibility and reduces equipment footprint requirements.
Power Generation and Ash Handling
Power plants use slurry pumps for handling fly ash, bottom ash, ash pond sediment, and abrasive byproducts generated during combustion and material handling processes. Heavy-duty wear components and high-solids handling capability help maintain reliability in abrasive ash transfer applications with demanding operating conditions.
Marine, Ports, and Waterway Maintenance
Ports, shipyards, and marine contractors use submersible slurry pumps for berth maintenance, sediment removal, dock cleanup, and underwater excavation projects. Their submerged operation allows efficient pumping in deep water, confined marine areas, and applications where floating or land-based pump systems may be difficult to deploy.
Remote Copper Mine Improves Tailings Transfer Reliability with EDDY Pump – Case Study
The Problem
A copper mining operation in South America was transferring abrasive tailings slurry from a remote settling pond located nearly 1,800 feet from the processing area. The existing centrifugal pump system struggled with slurry concentrations exceeding 55% solids by weight, causing repeated clogging, severe impeller wear, and unplanned shutdowns every 10 to 14 days. The operation was losing an estimated 18 to 20 hours of production each month due to maintenance and pump replacement requirements.
The Solution
The mine replaced the existing system with an EDDY Pump HD-8000 Submersible Slurry Pump configured with High Chrome wear components and a heavy-duty mechanical seal system for continuous abrasive slurry handling. The pump was deployed directly within the tailings pond to eliminate suction limitations and maintain stable solids transfer. Operating at flow rates exceeding 2,500 GPM, the system continuously transferred dense tailings containing coarse particles up to 5 inches in diameter.
The Result
After installation, the EDDY Pump system reduced unplanned maintenance shutdowns by more than 60% and extended wear component life from roughly two weeks to over three months of operation. The mine improved overall slurry transfer stability, increased tailings movement efficiency, and recovered approximately 200 additional operating hours annually that were previously lost to maintenance-related downtime.

Frequently Asked Questions
What types of slurry can EDDY Pump Slurry Pumps handle?
EDDY Pump Submersible Slurry Pumps are designed to handle abrasive, high-solids, and viscous slurries, including mining tailings, dredged sediment, wastewater sludge, drilling mud, ash slurry, sand, gravel, and industrial waste. The pump design allows efficient movement of material with high solids concentrations that commonly cause clogging in conventional centrifugal pumps.
Are spec sheets or pump curves available for each model?
Yes. Detailed spec sheets and pump performance curves are available for individual submersible slurry pump models. These documents provide information such as flow range, head range, solids handling capability, dimensional data, power requirements, and material configurations to support proper pump selection and system design.
When should I choose a submersible slurry pump instead of a self-priming slurry pump?
A submersible slurry pump is typically preferred when the pump must operate directly inside the slurry, such as in ponds, pits, lagoons, tanks, or underwater dredging applications. Fully submerged operation eliminates suction lift limitations and improves solids capture efficiency in high-solids environments where self-priming pumps may struggle with long suction lines or difficult material conditions.
How large a solid can pass through the pump?
Solids handling capability varies by model size. Larger models in the product line can pass solids up to 11 inches in diameter, making them suitable for coarse material, debris-laden slurry, and abrasive sediment transfer applications.
What is the advantage of a fully submersible slurry pump?
A fully submersible configuration allows the pump to operate directly inside the slurry, eliminating suction lift limitations and improving solids capture efficiency. This setup is particularly beneficial in deep pits, ponds, lagoons, tanks, and underwater dredging applications.
Are these pumps available in different material constructions?
Yes. EDDY Pump Submersible Slurry Pumps are available in High Chrome, Stainless Steel, Duplex Stainless Steel, and Ductile Iron configurations, depending on abrasion resistance, corrosion resistance, and application requirements.
Can the pumps operate in both horizontal and vertical positions?
Yes. The pumps can be deployed in either horizontal or vertical orientations depending on the installation layout, dredging setup, or operational constraints at the job site.
What factors should be considered when selecting the right model?
Pump selection should be based on required flow rate, total dynamic head, slurry density, solids concentration, particle size, discharge distance, operating depth, and production requirements. Material abrasiveness and system layout should also be evaluated during sizing. Read More
Are electric and hydraulic configurations available?
Yes. EDDY Pump Submersible Slurry Pumps are available in both electric and hydraulic drive configurations. Electric pumps are commonly used in fixed installations with available power infrastructure, while hydraulic configurations are often selected for mobile, remote, excavator-mounted, or variable-duty dredging applications.
What maintenance advantages does the EDDY Pump design provide?
The non-clog pump design reduces internal recirculation and minimizes blockages commonly associated with conventional slurry pumps. This helps lower maintenance frequency, reduce downtime, and extend component life in abrasive slurry applications.
