Operational Use Cases
Dredging and Sediment Removal
The 200 HP HPU provides the hydraulic output needed to power 4-inch dredge pumps and cutterheads for canal dredging, marina maintenance, riverbank stabilization, industrial pond cleanouts, and nearshore sediment removal. Its dual-circuit design supports both pumping and solids agitation, enabling higher production rates.
Environmental Remediation
Ideal for projects involving sludge removal, contaminated sediment extraction, and low-impact remediation in restricted or sensitive sites. The remote operation capability enables safe control when handling hazardous materials or during shallow-water cleanups.
Construction and Civil Infrastructure
Used for powering hydraulic pumps and tools in trenching, foundation work, slurry transfer, cofferdam support, and dewatering activities. The mobile skid or trailer setup makes it suitable for fast-moving construction workflows.
Municipal and Utility Services
Supports wastewater plant maintenance, stormwater basin dredging, lagoon restoration, and general municipal pumping tasks. The reliable 200 HP output ensures consistent flow and pressure for long operating cycles.
Mining and Aggregate Operations
Provides hydraulic power for tailings pond management, slurry transfer lines, and auxiliary tools in mining sites. The dual circuit system enhances performance in abrasive, high solids environments.
Marine and Coastal Operations
Performs efficiently on barges, pontoons, and floating platforms for dock construction, harbor cleanouts, shoreline maintenance, and coastal erosion control. The remote-controlled HPU enables safe operation in offshore and confined marine environments.
Agriculture and Irrigation
Useful for pond dredging, drainage improvement, irrigation system maintenance, and slurry movement. The high-pressure output supports large-scale farming and water management systems.
High Solids Dredging in a Confined Industrial Pond
Case Study
The Challenge
A manufacturing facility needed to remove dense, abrasive sludge from a deep industrial wastewater pond that had accumulated years of settled solids. The work area had narrow access points and soft ground conditions, restricting the use of larger equipment. The material required both strong hydraulic pumping and continuous agitation to maintain flow. The contractor’s existing single-circuit system lacked the power and control to handle the high solids load and maintain production rates.
The Solution
The EDDY 200 HP Hydraulic Power Unit was selected for its dual-circuit, open-loop design, delivering 40 GPM at 5000 psi on the main pump circuit and 25 GPM at 4500 psi to the cutterhead. This allowed the pump and agitation tool to run simultaneously without pressure loss. The remote operation feature supported safe deployment around the confined pond, and the integrated cooling and high-pressure filtration ensured consistent performance while handling abrasive slurry. The skid-mounted configuration enabled fast setup in the limited-access zone.
The Result
The contractor achieved more stable suction and significantly improved material movement, increasing production rates by more than 35 percent compared to their previous setup. The project was completed two weeks ahead of schedule, with no unplanned downtime and reduced maintenance requirements. The 200 HP HPU provided the power, reliability, and control needed to remove compacted sludge from the confined industrial site efficiently.
