Cable or Barge Deployed Dredge Pump with Water Jetting
Cable-mounted dredge pumps deliver high-capacity solids handling from 4-inch through 12-inch sizes with both hydraulic and electric power options. Designed for dense slurry and abrasive materials, they typically deliver up to 7,000 GPM and production rates of up to 600 cubic yards per hour, handle solids up to 11 inches, and operate at depths of up to 100 ft. Jetting ring agitators fluidize compacted sediment for maximum throughput, and patented non-clog rotor technology ensures continuous pumping with minimal downtime. These rugged systems integrate easily with cranes, excavators, or barge-mounted A-frames to support demanding dredging, mining, and industrial slurry applications.

Applications Across Industries
Dredging and Marine Construction
Cable-mounted dredge pumps are widely used in marine dredging and construction projects for sediment removal, channel deepening, and harbor maintenance. Their ability to operate at depth, handle dense slurry, and integrate with barges, cranes, and A-frame systems makes them well-suited for offshore and inland waterway projects.
Mining and Mineral Processing
In mining operations, these pumps handle abrasive slurries, including tailings, sand, and mineral concentrates. High solids capability and large particle handling support continuous material transfer from pits, ponds, and processing areas, while the non-clog design reduces downtime in demanding, high-wear mining environments.
Sand and Aggregate Operations
Sand and aggregate producers use cable-mounted dredge pumps to recover material from pits, rivers, and reservoirs. High flow rates and consistent slurry transport enable efficient extraction of sand, gravel, and silt, supporting both production dredging and material transfer to processing or stockpiling locations.
Environmental Remediation
For environmental dredging and remediation projects, cable-mounted pumps provide controlled sediment removal in lakes, lagoons, and contaminated waterways. The jetting ring system helps loosen compacted material while maintaining stable flow, supporting sediment management, restoration, and cleanup operations with reduced disruption to surrounding areas.
Oil and Gas
In oil and gas applications, these pumps are used for handling drilling mud, slop, tank bottoms, and contaminated slurries. Their ability to move high-viscosity, high-solids materials makes them suitable for upstream, midstream, and downstream support operations, including cleanup, transfer, and waste handling.
Power Generation and Industrial Ash Handling
Cable-mounted dredge pumps are commonly applied in fly ash and coal ash management for power plants. They transport dense ash slurries from ponds and containment areas, supporting plant maintenance, environmental compliance, and long-distance slurry transfer with consistent performance.
Municipal and Industrial Wastewater
Municipal and industrial facilities use these pumps for sludge removal, lagoon cleaning, and basin maintenance. High solids handling and submerged operation enable efficient transfer of thick sludge, grit, and biosolids, helping facilities maintain capacity, reduce manual cleanup, and support long-term system reliability.
Flood Control and Water Management
In flood control and water management projects, cable-mounted dredge pumps assist with sediment from channels, reservoirs, and retention basins. Their depth capability and high production rates support preventive maintenance and restoration efforts to improve flow capacity and reduce flood risk.
Maintaining Berth Depth in an Active Coastal Port
Case Study
The Problem
A coastal port authority struggled to maintain the required berth depth along an active docking area with constant vessel traffic. Fine silt, sand, and debris accumulated along the berth face, reducing clearance for ships. The restricted work zone and tight operating envelope ruled out cutter dredges and large mechanical equipment, while shutting down port operations was not feasible.
The Solution
EDDY Pump’s hydraulic cable-mounted dredge pump was suspended from a crane and positioned precisely along the berth line. The pump’s non-clog design and integrated jetting ring agitator fluidized compacted sediment, allowing stable slurry intake and controlled material removal. Hydraulic power from site equipment enabled continuous operation without disrupting vessel movements.
The Result
Berth depth was restored and maintained without interrupting port operations. The system delivered consistent dredging output, eliminated pipeline blockages, and reduced maintenance intervention. The port authority achieved a flexible, low-impact dredging solution suited for ongoing berth maintenance in high-traffic marine environments.

Frequently Asked Questions
What is a cable-mounted dredge pump?
A cable-mounted dredge pump is a high solids slurry pump suspended by cable and deployed vertically or horizontally into water or pits. It is commonly used for deep dredging, sediment removal, and slurry transfer where excavator reach or shoreline access is limited.
What is the difference between electric and hydraulic cable-mounted dredge pumps?
Hydraulic models are powered by excavator auxiliary circuits or hydraulic power units and are ideal for mobile or remote sites. Electric models use an electric motor powered by a generator and VFD, offering precise speed control and stable performance where electrical infrastructure is available.
What materials can these pumps handle?
Both electric and hydraulic cable-mounted dredge pumps are designed to handle dense slurry, sludge, sand, silt, tailings, ash, drilling mud, and other abrasive or high viscosity materials. They are engineered to handle solids concentrations of 40–70% by weight.
What sizes are available for cable-mounted dredge pumps?
EDDY Pump’s cable-mounted dredge pumps are available in sizes ranging from 4 to 12 inches in discharge diameter. The correct size depends on the required flow rate, solids size, production targets, and deployment depth.
How deep can a cable-mounted dredge pump operate?
Cable-mounted dredge pumps are commonly operated at depths of up to 100 feet. Actual operating depth depends on cable length, deployment method, and project conditions such as slurry density and pipeline layout.
How does the jetting ring system improve dredging performance?
The jetting ring injects high-volume, low-pressure water around the pump inlet to loosen compacted sediment. This improves slurry consistency, reduces air entrainment, and increases overall production while minimizing the risk of clogging.
Can cable-mounted dredge pumps handle large solids?
Yes. Depending on pump size, these systems can pass large solids, often up to 11 inches in diameter. The non-clog pump design allows oversized and irregularly shaped material to pass through the pump without frequent blockages.
What power requirements are needed for electric cable-mounted dredge pumps?
Electric models typically require a generator and a variable-frequency drive sized for the pump motor, with motor ratings commonly ranging from 100 HP to 700 HP. Exact power requirements depend on pump size, material type, and operating conditions.
What support equipment is required to operate these pumps?
Typical support equipment includes discharge slurry hose or pipeline, lifting cables or crane systems, a jetting ring water pump, and optional instrumentation such as flow meters and pressure gauges. Hydraulic models also require a suitable hydraulic power source.
What industries commonly use cable-mounted dredge pumps?
These pumps are widely used in dredging and marine construction, mining, sand and aggregate, environmental remediation, oil and gas, power generation, wastewater treatment, and flood control projects that require high solids-handling and deep deployment.
