Environmental Sediment Removal
Used for sediment remediation in waterways, stormwater ponds, and contaminated basins where controlled dredging and targeted material removal are required to minimize disturbance outside the work zone.
Paper and Pulp Sludge Removal
Pumps pulp slurry, fiber-rich sludge, and process waste from clarifiers, settling basins, and storage ponds where conventional pumps often experience plugging or reduced flow efficiency.
Industrial Tank and Sump Cleaning
Supports removal of settled solids, abrasive slurry, and accumulated sludge from process tanks, pits, and industrial sumps where direct excavator access improves material recovery and cleanup efficiency.
Lined Pond Maintenance
Configured with liner-safe wheels and controlled agitation systems for dredging operations inside lined ponds used in mining, wastewater, and industrial containment applications where liner protection is critical.
Remote and Confined Area Dredging
Allows dredging in areas where conventional dredges are difficult to mobilize, including remote sites, narrow basins, temporary ponds, and confined industrial work zones with limited access.
Case Study: Excavator Pump Attachment for Tailings Removal
The Problem
A mining operation needed to remove more than 18,000 cubic yards of settled tailings from a lined containment pond that had lost nearly 35% of its active storage capacity. Previous dredging methods created concerns about damaging the liner surface, while conventional pumps struggled with the dense, abrasive slurry and high solids concentration. The site also had limited access for larger dredging equipment, making mobilization difficult and increasing project delays.
The Solution
The operation deployed an EDDY Pump 6-Inch Excavator Pump Attachment configured with liner-safe wheels and a water jetting ring to dredge material from the lined pond safely. Mounted directly to a hydraulic excavator, the system allowed operators to maintain controlled positioning while pumping high-solids slurry directly from the pond floor. The EDDY Pump system handled solids concentrations that other pumps were not able to, while transferring material through a long discharge pipeline to the designated disposal area.
The Result
Using the EDDY Pump excavator dredging system, the mining operation restored approximately 16 million gallons of pond capacity while completing the dredging campaign ahead of schedule. The project maintained continuous production rates exceeding 150 yd³/hr without liner damage or major pipeline plugging events. By avoiding liner repair costs and reducing mobilization requirements compared to a conventional dredge setup, the site significantly lowered overall project downtime and operational disruption.

Talk To About Any Question?
Excavator Pump Attachment – FAQs
What is an excavator pump attachment used for?
An excavator pump attachment converts a hydraulic excavator into a mobile dredging and slurry pumping system. It is commonly used for pond dredging, sludge removal, mine tailings recovery, sand excavation, industrial cleanup, and high-solids material transfer in areas where conventional dredges are difficult to deploy.
What materials can the attachment pump?
The system is designed to handle abrasive and high-solids materials including slurry, sludge, sediment, sand, drilling mud, mine tailings, grit, fly ash, coal ash, and industrial waste slurry. The non-clog pump design allows it to manage materials that typically create plugging or excessive wear in conventional pumps.
What excavator size is required to operate the attachment?
Excavator requirements depend on the attachment size, hydraulic demand, and production target. Smaller 4-inch and 6-inch systems typically operate on 20 to 45 ton excavators, while larger 8-inch to 12-inch models generally require 60 to 94 ton carriers for stable operation and sufficient hydraulic power.
Can the excavator pump attachment operate with a hydraulic power unit instead of excavator hydraulics?
Yes. The attachment can operate from the excavator’s auxiliary hydraulic system or from a standalone hydraulic power unit (HPU). This allows greater flexibility when excavator hydraulic capacity is limited or when a dedicated hydraulic system is preferred for continuous dredging operations.
How much solids concentration can the system handle?
Depending on the material properties and system configuration, EDDY Pump excavator attachments are capable of pumping slurry with solids concentrations up to 40 to 70%, depending on material, slurry density, pump size, pipeline layout, and site conditions. Actual performance depends on particle size, slurry density, pipeline layout, and the selected pump model.
Are different cutterhead options available for different materials?
Yes. Multiple cutterhead and agitation configurations are available to match specific dredging conditions. Options include standard cutterheads for general dredging, auger heads for dense sludge, water jetting rings for compacted material, mixer heads for slurry re-suspension, and liner-safe wheels for lined ponds.
Can the system be used in lined ponds or containment areas?
Yes. The attachment can be configured with liner-safe wheels designed to reduce direct contact with geomembrane liners during dredging. This is commonly used in mining ponds, wastewater lagoons, and industrial containment systems where liner protection is critical.
What discharge distances can the attachment support?
Discharge capability depends on the selected pump size, slurry density, solids concentration, elevation changes, and pipeline design. Larger models offer high flow rates and head capabilities up to 240 feet, allowing material transfer across long pipeline distances in demanding dredging applications.
Is rental equipment available for temporary projects?
Yes. EDDY Pump offers rental systems for short-term dredging work, emergency cleanup, shutdown support, pilot testing, and seasonal operations. Rental packages can include the excavator pump attachment, hydraulic power units, discharge hose, and supporting dredging accessories. Rent-to-own options are also available.
What information is needed to size the correct excavator pump attachment?
Proper sizing typically requires information about the material being pumped, solids concentration, particle size, production goals, dredging depth, discharge distance, available excavator hydraulic capacity, and site access conditions. This information helps determine the appropriate pump size, cutterhead configuration, and hydraulic requirements for the project.
