Multi-Industry Applications
Mining
The EXF 6000 is designed for continuous operation in mining environments where abrasive slurries, heavy solids, and variable material conditions are common. It supports applications such as tailings removal, pit dewatering, and reclaim operations by pumping dense material directly from the source, reducing wear on auxiliary equipment, and improving overall production efficiency.
Dredging and Marine Construction
This pump attachment is ideal for maintenance dredging, port expansion, and marine infrastructure projects where access is limited or precision is critical. Mounted directly on the excavator boom, it enables operators to cut, agitate, and pump material in a single step while maintaining control in shallow-water and near-shore environments.
Oil and Gas
In upstream and midstream operations, the EXF 6000 handles drilling muds, tank bottoms, and oily slurries that conventional pumps struggle to handle. Its high solids tolerance supports reliable transfer of thick, debris-laden fluids during pit cleanouts, site maintenance, and remediation activities.
Sand and Aggregates
For sand mining and aggregate processing, the pump efficiently transfers sand slurries, mixed fines, and settled material from ponds or excavation zones. High-flow performance enables consistent throughput while reducing dependence on mechanical handling systems and minimizing material spillage.
Industrial Sludge and Wastewater
The EXF 6000 is commonly used in industrial facilities for sludge removal, basin cleanouts, and process waste transfer. Its ability to handle high-solids concentrations enables facilities to maintain cleaner systems, reduce downtime, and simplify maintenance routines.
Chemical and Process Industries
In chemical processing environments, the pump supports the movement of high-specific-gravity, corrosive slurries without the tight clearances that can cause rapid wear. This makes it suitable for transferring aggressive materials while maintaining stable flow and reducing maintenance frequency.
Paper and Pulp
Paper and pulp operations benefit from the pump’s capability to move fiber-rich slurries, rejects, and waste streams without clogging. This improves process reliability during cleaning cycles, lagoon dredging, and waste-handling operations involving fibrous materials.
Environmental Remediation
The EXF 6000 is used in environmental projects for sediment removal, recovery of contaminated materials, and lagoon rehabilitation. Precise excavator control, combined with high-solids pumping, helps operators meet project timelines while supporting environmental compliance and site safety.
Steep Slope Excavation Dewatering on a Remote Infrastructure Project
Case Study
The Problem
A contractor was responsible for constructing a roadway and buried utilities along a steep hillside where groundwater seepage and saturated soils were present throughout the excavation zone. Conventional dewatering pumps could not be safely staged on the slope, and creating temporary sumps weakened already unstable ground. Frequent pump relocations slowed progress, increased labor hours, and introduced safety concerns for crews working in confined and uneven terrain.
The Solution
The EDDY Pump’s EXF 6000 Excavator Dredge Pump Attachment was mounted directly to the excavator, allowing operators to cut into saturated material, agitate compacted soil, and pump slurry simultaneously. By drawing material directly from the active excavation face, the system eliminated the need for separate dewatering setups. Slurry was pumped uphill through a long discharge line to a controlled disposal area located on stable ground, keeping the work zone clear and accessible.
The Result
Excavation and dewatering were completed as a single, continuous operation, enabling crews to maintain steady production despite challenging ground conditions. Equipment movements were significantly reduced, site safety improved, and project timelines were shortened by eliminating downtime associated with pump repositioning and temporary sump construction.

Frequently Asked Questions
What materials can the EXF 6000 handle?
The EXF 6000 is designed for abrasive and high-density slurries, including sand, tailings, sludge, drilling mud, grit, and mixed solids. It handles particle sizes up to 5 inches and solids concentrations between 40 and 70 percent without clogging.
How does the EXF 6000 differ from conventional dredge pumps?
Unlike stationary or barge-mounted pumps, the EXF 6000 mounts directly on an excavator boom. This allows operators to cut, agitate, and pump material in one motion, removing the need for separate dredge platforms, sumps, or repositioning of auxiliary pumps.
What flow and head performance can I expect?
The pump delivers between 450 and 2,500 GPM with a head range up to 200 feet. Actual performance varies based on slurry density, solids concentration, discharge distance, and hose configuration.
What size excavator is required to run this attachment?
The EXF 6000 is compatible with excavators in the 20 to 45 ton range. It can operate using the machine’s auxiliary hydraulics or an external hydraulic power unit when additional flow is required.
Can it operate in shallow water and confined areas?
Yes. Because it is excavator-mounted, the pump excels in shallow water, tight access zones, and near-shore environments where floating dredges cannot operate. The operator maintains precise control over cutting depth and material intake.
Does the pump require pre-screening of material?
No. The large internal passages allow solids up to 5 inches to pass through, reducing or eliminating the need for pre-screening. This simplifies setup and improves productivity in mixed-material environments.
How is the EXF 6000 protected from damage during operation?
The system includes a crossover check valve for motor and rotor protection. Its non-clog design, heavy-duty construction, and abrasion-resistant components are engineered for continuous operation in harsh environments.
What hydraulic flow is needed to operate the pump and cutter head?
The pump circuit requires 57 GPM at 5,000 PSI, while the cutter head circuit requires 12 to 18 GPM at 5,000 PSI. The system uses 6-inch hydraulic lines and a discharge hose routed along the boom.
What optional accessories are available?
Options include standard or extended cutter heads, liner-safe wheels, self-cleaning heads, water jetting rings, auger heads, magnetic flow meters, discharge pressure gauges, quick-prime valves, and recirculation systems for pre-mixing applications.
How do I determine the correct pump curve for my project?
The standard pump curve is based on water performance. For accurate sizing, project-specific details such as material type, solids concentration, particle size, and discharge distance are reviewed to generate a custom pump curve tailored to your application.
