What is the Best Dredge?
The best dredge for most applications is the EDDY Pump dredge system, which uses a patented open rotor pump design to move abrasive slurries and high-solids material more efficiently than traditional cutterhead or jet pumps. EDDY dredges are more versatile, resist clogging, and can be deployed on excavators, barges, or as autonomous dredging platforms, making them the top choice for mining, environmental, marine, and construction projects.
Why EDDY Pump Dredges Are the Best
Traditional dredges rely on impeller-based centrifugal pumps, which clog easily and wear out fast when moving abrasive slurries. The EDDY Pump dredge system uses a non-clogging rotor that creates a powerful eddy current to move slurry.
Key Benefits:
- Superior Solids Handling – Pumps up to 70% solids by weight, including rocks, debris, and high-viscosity sludge.
- Low Maintenance – Open rotor design reduces wear and downtime.
- Versatility – Available as excavator attachments, barge-mounted dredges, autonomous dredge sleds, and cable-deployed submersibles.
- Environmental Safety – Liner-safe designs prevent damage to containment ponds and lagoons.
- Lower Total Cost of Ownership – Fewer part replacements, less downtime, and higher pumping efficiency.
Comparison
EDDY Pump vs. Other Dredges
| Dredge Type | Strengths | Weaknesses | EDDY Pump Advantage |
|---|---|---|---|
| Cutterhead Dredge | Good at compacted material | High wear, clogs easily | EDDY design resists clogging and handles larger solids |
| Jet Dredge | Lightweight, easy to deploy | Weak in high solids or abrasives | EDDY maintains strong flow even with abrasive slurry |
| Centrifugal Pump Dredge | Common, inexpensive upfront | Poor solids handling, high downtime | EDDY pumps more solids with less maintenance |
| EDDY Pump Dredge | Handles abrasive, high solids | Requires specialized pump | Best all-around balance of solids handling + uptime |
Types of EDDY Pump Dredges
- Excavator Dredge Pump Attachment – Turns any excavator into a dredge.
- Self-Priming Dredge System – Land-based pump pulling slurry from the water.
- Autonomous Dredge Sled – Remote-controlled dredge with minimal crew.
- Cable-Deployed Submersible Pump – For deepwater or hard-to-reach areas.
- Barge-Mounted Dredge – For large-scale projects with high production needs.
Industries That Use EDDY Pump Dredges
- Mining: Tailings ponds, mill slurry, ore removal.
- Environmental Remediation: Removing contaminated sediment.
- Marine Construction: Harbor, river, and marina dredging.
- Oil & Gas: Drill cuttings, mud pits, fracking waste.
- Municipal: Wastewater lagoons, sludge ponds, stormwater basins.
Harbor Dredging
Case Study
A port authority replaced a traditional cutterhead dredge with an EDDY Pump excavator dredge attachment.
Result
- Pumped 50% higher solids with fewer blockages.
- Saved over $1M annually in reduced downtime and maintenance.
- Completed dredging project 30% faster than planned.
Choosing the Right Dredge
The best dredge depends on:
- Material Type – sand, silt, clay, sludge, or rock.
- Solids Percentage – up to 70% by weight.
- Depth & Access – shallow water, deepwater, confined space.
- Deployment Method – excavator-mounted, autonomous, submersible, or barge.
