PUMP CURVE

A pump curve shows how the 6-Inch HD 6000 Hydraulic Diver Operated Pump performs across different flow and head conditions, helping operators evaluate system capability for underwater dredging applications. Actual slurry performance will vary based on material density, solids concentration, particle size, discharge distance, and pipeline configuration. Because high-solids dredging conditions differ significantly from water-based testing, custom pump curve evaluation is recommended for accurate system matching and production planning.

Typical Industrial Applications

Dredging

Industrial Sludge Removal

The 6-Inch Hydraulic Diver Operated Pump is used for removing settled sludge, slurry, and waste solids from industrial ponds, process tanks, lagoons, and containment areas. The diver-operated configuration allows controlled material removal in submerged environments where conventional equipment access may be limited.

Chemical & Industrial

Mining and Tailings Pond Dredging

Mining operations use the system for dredging high-solids slurry, tailings, sediment, and abrasive material from ponds, pits, and containment areas. Its ability to handle large solids and dense slurry supports continuous pumping in demanding mining conditions.

Construction & Tunneling

Marine and Underwater Dredging

The pump supports underwater dredging operations in harbors, canals, marinas, intake structures, and submerged excavation areas. Diver-controlled operation provides precise dredging capability in locations where maneuverability and controlled material removal are critical.

Industrial Wastewater & Process Lagoons

Industrial Dewatering Operations

The system is used for dewatering applications involving heavy sediment, slurry, and solids-laden water that may overwhelm standard dewatering pumps. The non-clog pump design helps maintain stable operation during abrasive and debris-loaded pumping conditions.

Pulp and Paper

Sand, Sediment, and Slurry Transfer

The pump is suitable for transferring sand, silt, sludge, and abrasive slurry in dredging and material transport applications. High-solids handling capability allows operators to move dense material efficiently while reducing clogging risk.

Pulp and Paper

Power Plant and Utility Basin Cleaning

Power plants and utility facilities use diver-operated dredging systems for removing accumulated sediment, ash slurry, and debris from cooling ponds, intake basins, and containment structures. The compact underwater configuration supports dredging in restricted-access areas without requiring large floating dredges.

Confined Pond Dredging Case Study

Industrial processing facility with settling ponds affected by heavy sludge buildup requiring confined-access dredging solution

The Problem

An industrial processing facility was experiencing severe sludge accumulation inside a confined settling pond used for process water management. The sludge contained abrasive solids with concentrations estimated between 50–60%, creating repeated plugging issues for the facility’s existing pumping system. Material buildup had reduced effective pond capacity by nearly 35%, while unstable bottom conditions and limited access prevented the use of larger conventional dredging equipment. The facility required a controlled dredging solution capable of operating in restricted underwater conditions without shutting down nearby operations.

The Solution

The facility deployed the EDDY Pump 6-Inch HD 6000 Hydraulic Diver Operated Pump to perform targeted underwater sludge removal inside the confined pond. The diver-operated configuration allowed operators to control material removal around tight corners, submerged piping, and structural obstructions while maintaining steady slurry transfer. Operating with production rates averaging approximately 170 yd³/hr, the EDDY Pump system handled abrasive sludge containing solids up to 5 inches without frequent clogging interruptions. A Doppler slurry flow monitoring system was also used to maintain stable pipeline flow during discharge operations.

The Result

Over 4,000 cubic yards of accumulated sludge were removed during the dredging campaign, restoring significant operational capacity to the settling pond. The EDDY Pump system reduced pumping interruptions associated with clogging and maintained continuous slurry transfer throughout the project. The facility completed the dredging operation without deploying large floating dredges or shutting down adjacent processing areas, helping reduce operational disruption and improve long-term sludge management performance.
