Custom Mixer Dredge
We design and manufacture custom dredge systems engineered around your project’s exact operational requirements — including flow rate, total dynamic head, solids concentration, particle size distribution, and site-specific conditions. Each unit integrates EDDY Pump’s non-clogging, high-solids slurry technology with purpose-built agitation, automation, and structural configurations to deliver maximum throughput, reduced wear, and reliable performance in abrasive, high-viscosity, or high-solids gain dredging applications.
Key Advantages of Custom Dredge Solutions
Engineered for High-Viscosity, High-Solids Applications
Custom dredging systems like The Egg Beater Dredge are specifically designed to handle materials that conventional dredges struggle with — including compacted muds, thixotropic slurries, and high specific gravity mixtures. Through powerful pre-agitation and mixing, the system liquefies dense materials before they reach the pump, ensuring a steady, uninterrupted flow and eliminating issues such as clogging or starvation.
Maximum Pumping Efficiency Without Boosters
The integrated pump-agitator-suction configuration enables the system to move thick, heavy material thousands of feet through discharge pipelines without additional booster pumps. This translates directly into reduced capital costs, simplified operations, and higher production rates in challenging dredging conditions.
Non-Clogging Performance and Consistent Production
At the core of every EDDY custom dredge is our patented pump technology — a unique design that leverages synchronized eddy currents to achieve superior solids handling and flow characteristics. Unlike centrifugal or positive displacement pumps, it maintains constant production even with high concentrations of abrasive, viscous, or corrosive materials.
Automation-Ready for Unmanned Operations
The Egg Beater Dredge can be fully integrated into autonomous dredging systems, enabling efficient large-area coverage with minimal labor. By anchoring cables to shore, the dredge can operate without an onboard crew, thereby reducing operational costs and enhancing safety in remote or hazardous environments.
Heavy-Duty Throughput and Production Capacity
Powered by HD Series EDDY Pumps, custom dredges deliver flow rates up to 4000 GPM and over 400 ft of head. This unmatched hydraulic performance allows operators to meet demanding throughput requirements while minimizing wear, downtime, and total ownership costs.
Proven, USA-Built Reliability
Since 1984, EDDY Pump has been a leader in innovation in dredging technology. Our custom systems are field-tested and engineered for long-term reliability in abrasive, high-solids, and chemically aggressive environments — making them the preferred choice for operators seeking maximum ROI and minimal maintenance.

EDDY Pump – Custom Mixer Dredge
PUMP CURVE
A pump curve illustrates how the system delivers flow at varying head levels, helping verify performance under dense, abrasive slurry conditions. For the Custom Mixer Dredge, selecting the correct curve ensures stable throughput, efficient transport of high-solids material, and reliable operation over long discharge distances and in heavy-duty dredging environments.
Where Custom Dredges Deliver Results
Custom dredging solutions, such as The Egg Beater Dredge, are designed to perform in environments where conventional systems fail — delivering consistent flow, high solids handling, and reliable production across a wide range of heavy-duty applications. Here’s where these systems make the greatest impact:
Mining & Mineral Processing
Designed to handle abrasive tailings, slurry, and high-specific-gravity ore residues, custom dredges excel in mine pond cleanup, tailings dam management, and the transportation of dense mineral suspensions over long distances without the need for booster pumps. Their durability and throughput help reduce downtime and improve recovery efficiency.
Wastewater Treatment
Facilities processing thick sludge, biosolids, or grit-laden wastewater benefit from the dredge’s ability to maintain stable flow rates and prevent clogging, even with high-viscosity or fibrous materials. This ensures reliable operation during lagoon cleaning, digester maintenance, and solids handling tasks.
Marine Construction & Coastal Restoration
From dredging navigation channels and harbors to reclaiming land and rebuilding shorelines, the system’s robust pumping and agitation capabilities enable efficient handling of consolidated sediments, silt, and organic debris — critical for large-scale marine infrastructure and coastal protection projects.
Oil, Gas & Petrochemical
The dredge’s corrosion-resistant construction and non-clogging performance make it ideal for handling heavy drilling muds, refinery byproducts, and contaminated sediments. Operators can manage viscous slurries and hazardous residues safely while minimizing manual intervention and downtime.
Environmental Remediation
Whether removing contaminated sediments from industrial sites or clearing sargassum and organic buildup from coastal zones, custom dredges provide precise, continuous removal with minimal environmental disturbance — essential for cleanup, restoration, and compliance projects.
Agriculture & Pulp Processing
In lagoons, retention ponds, and biomass processing facilities, the dredge efficiently pumps slurry with high fiber content or organic load. Its ability to handle variable viscosity and solids content ensures consistent performance in applications like manure lagoon cleaning, pulp waste removal, and fertilizer slurry transport.
Autonomous Sargassum Harvesting and Disposal for Coastal Restoration
Case Study
The Challenge
A coastal restoration project in the Gulf region was facing severe operational and environmental setbacks due to massive seasonal sargassum accumulation. The thick, fibrous mats blocked water flow, disrupted marine habitat, and impeded navigation near shorelines. Manual removal methods were labor-intensive, costly, and inconsistent, often requiring large crews and frequent interruptions due to equipment clogging and limited pumping capacity.
The Solution
To overcome these challenges, EDDY Pump deployed a custom Egg Beater Dredge configured for fully autonomous, cable-anchored operation. The dredge’s twin agitators aggressively mixed the dense organic material into a pumpable slurry. At the same time, the high-solids HD series pump transported the mixture directly through extended discharge pipelines without the need for booster stations. Remote monitoring and automated positioning enabled the system to continuously dredge a wide operational area without requiring onboard personnel.
The Result
The autonomous dredging system successfully removed over 300 tons of sargassum within a two-week window, restoring navigable waterways and improving water quality ahead of schedule. Operational costs were reduced by more than 60% due to minimal labor requirements and reduced equipment downtime. The project demonstrated the effectiveness of the Egg Beater Dredge in large-scale coastal maintenance operations, setting a new benchmark for environmentally responsible and cost-efficient sargassum management.
