EDDY Pump – 8 Inch HD 8000 Heavy Duty Slurry Pump – Pump Curve
PUMP CURVE
The pump curve for the 8-Inch EXF 8000 excavator dredge pump attachment illustrates how flow and head performance change as slurry density and discharge resistance increase. It helps operators match excavator hydraulic power to target production rates, verify performance when pumping large solids at high concentrations, and maintain stable output during continuous dredging without overloading the hydraulic system.

Target Industries
Mining
The EXF 8000 supports continuous removal of mine tailings, overburden, and slurry with high solids content. Its non clog hydraulic dredge pump design handles abrasive materials efficiently, improving production rates while reducing wear and unplanned downtime in active mining operations.
Sand and aggregate
Engineered for demanding sand and aggregate recovery, the excavator mounted dredge pump delivers consistent high flow while handling large particles. It supports efficient pit dredging, wash plant feed, and material relocation with reduced water usage and improved solids concentration.
Oil and gas
For oil sands, drilling mud, and contaminated slurry handling, the heavy duty dredge pump provides reliable performance in harsh environments. Its ability to move high viscosity and high specific gravity materials supports cleanup, transfer, and processing operations across upstream and midstream sites.
Industrial sludge and wastewater
The excavator slurry pump is well suited for industrial sludge removal, lagoons, and wastewater basins. High solids pumping capability minimizes dilution, improves handling efficiency, and supports maintenance dredging in treatment plants and industrial facilities.
Ports, harbors, and waterways
Used for maintenance dredging in confined or shallow waterways, the excavator dredging attachment allows precise sediment removal without large dredging vessels. This approach reduces mobilization costs while maintaining navigable channels and waterfront infrastructure.
Environmental and remediation projects
The non-clog dredge pump design supports contaminated sediment removal, remediation dredging, and environmental cleanup projects. Controlled hydraulic operation allows targeted material extraction while limiting turbidity and improving site compliance.
Case Study
The Problem
An industrial wastewater treatment facility experienced reduced settling basin capacity due to long term accumulation of dense, abrasive sludge. Conventional mechanical removal required partial draining, extended downtime, and frequent equipment clogging. The buildup limited treatment efficiency, increased maintenance costs, and disrupted normal plant operations.
The Solution
The EDDY Pump’s EXF 8000 excavator-mounted slurry pump was deployed as a hydraulic dredge pump attachment to remove sludge directly from the basin. Its non-clog design handled high solids material without dilution, while excavator mounting allowed precise positioning and controlled removal without shutting down the system.
The Result
The facility restored full basin capacity with faster sludge removal and minimal operational disruption. High solids pumping reduced water handling and disposal costs, while reliable performance minimized maintenance downtime. The project improved treatment efficiency, extended basin service life, and delivered a safer, more efficient dredging solution.

Frequently Asked Questions
What is the EXF 8000 dredge pump attachment designed for
The EXF 8000 is designed for high solids dredging, slurry pumping, and sediment removal in demanding environments. It is used for applications such as mining tailings removal, sand and aggregate dredging, industrial sludge handling, and environmental remediation where abrasive and high viscosity materials are present.
How does the non clog dredge pump technology work
The pump uses EDDY Pump’s patented technology that moves material through a fluid dynamics process rather than relying on tight clearances. This design allows large solids, debris, and abrasive material to pass through without clogging, reducing downtime and improving reliability in continuous dredging operations.
What type of excavators are compatible with the EXF 8000
The EXF 8000 is compatible with excavators in the 60 to 94 ton class. It can be powered through the excavator hydraulic system or an external hydraulic power unit, giving flexibility for land based, shallow water, or amphibious dredging applications.
What solids size and concentration can the pump handle
The EXF 8000 can handle solids up to 7 inches in diameter and operate with slurry concentrations between 40 and 70 percent solids. This high solids capability reduces water usage and increases overall dredging efficiency compared to traditional centrifugal pumps.
Can the EXF 8000 operate fully submerged
Yes, the pump is designed to operate as a submersible excavator pump attachment. It performs effectively in submerged, partially submerged, and shallow water conditions, making it suitable for ponds, lagoons, pits, and confined dredging areas.
What industries commonly use the EXF 8000
Industries include mining, sand and aggregate, oil and gas, industrial wastewater treatment, ports and waterways, and environmental remediation. It is particularly effective in applications requiring heavy duty slurry handling and abrasive material pumping.
What optional equipment is available for the EXF 8000
Optional equipment includes cutter heads, water jetting rings, recirculation systems, flow meters, and discharge pressure gauges. These options allow the excavator dredge pump attachment to be configured for specific material types, production goals, and site conditions.
How does an excavator mounted dredge pump compare to traditional dredges
An excavator mounted dredge pump offers faster mobilization, lower setup costs, and improved precision in confined spaces. It eliminates the need for large floating dredges while still delivering high solids pumping performance and controlled material removal.
What maintenance is required for the EXF 8000
Maintenance focuses on routine inspection of wear components, hydraulic connections, and optional accessories. The non clog pump design reduces wear caused by recirculation and blockage, helping extend service intervals and minimize unexpected downtime.
Is the EXF 8000 suitable for environmental and remediation projects
Yes, the EXF 8000 is well suited for environmental dredging and remediation. Its controlled hydraulic operation allows targeted sediment removal with reduced turbidity, making it effective for contaminated sediment cleanup and sensitive site conditions.
