The EDDY Pump Difference
EDDY Pump’s patented technology uses an open-rotor hydraulic design that moves material via kinetic energy rather than forcing it through tight internal clearances. Unlike centrifugal pumps, which rely on tight tolerances, EDDY Pumps allow solids to pass freely through the pump body without contacting wear points. In a 4-inch EDDY Pump, the clearance between the rotor and volute is wide enough to allow the passage of a man’s arm, while centrifugal pumps operate with far tighter tolerances. Across the full 1-inch to 12-inch EDDY Pump range, internal clearances scale from 1 to 12 inches. In the 8-Inch HD-8000, this design supports continuous pumping at 40 to 70 percent solids with particles up to 7 inches, allowing rocks, debris, sludge, sand, and dense slurry to move through without clogging or performance loss.
The 8-inch Slurry Pump (HD-8000 10×8) can be installed in horizontal or vertical configurations, making it easy to integrate into fixed plants, dredging systems, and mobile setups. Available in heavy-duty flex-coupled configurations and adaptable to hazardous environments, it combines installation flexibility with a non-clog hydraulic design that consistently outperforms centrifugal, vortex, and positive-displacement pumps in the most demanding high-solids applications.

Where the 8-Inch Slurry Pump Performs Best
Mining
The 8-inch HD-8000 slurry pump plays a critical role in mining operations, where abrasive slurries and high-solids concentrations are common. It is used for tailings transport, mineral processing, dewatering, and slurry transfer between stages. The pump’s ability to handle large particles and dense mixtures enables continuous operation while reducing wear-related downtime in both surface and underground mining environments.
Dredging
In dredging applications, this pump is used for sediment removal, channel deepening, harbor maintenance, and land reclamation projects. It efficiently moves sand, silt, clay, and debris over long distances without clogging. Its consistent performance under varying material conditions helps dredging operations maintain steady production rates and meet project timelines.
Oil and Gas
The pump is used in oil and gas operations to circulate drilling mud, transfer produced water, and handle waste slurries generated during drilling and well servicing. Its robust construction enables reliable operation in remote field locations where fluid properties vary frequently, and equipment access may be limited.
Sand and Aggregates
In sand pits and aggregate processing facilities, the pump moves abrasive sand mixtures from excavation points to processing or stockpiling areas. High flow capability allows operators to move large volumes efficiently, while the durable internal components help extend service life in high-wear environments.
Chemical Processing
Chemical processing plants use this pump to transfer abrasive or chemically aggressive slurries that can quickly damage standard pumps. The availability of specialized materials and sealing options enables safe handling of challenging fluids while maintaining consistent flow and reducing unplanned maintenance.
Power Generation and Ash Handling
In power plants, pumps transport fly ash and coal ash slurry from collection points to disposal or storage areas. Its ability to handle dense, abrasive ash slurries improves system reliability, reduces blockages, and supports continuous operation in demanding ash management systems.
Paper and Pulp
The pump supports paper and pulp operations by moving sludge, fiber-laden process streams, and waste byproducts. Its non-clog design allows it to handle fibrous materials without frequent shutdowns, helping mills maintain stable processing rates and reduce maintenance labor.
Wastewater and Industrial Sludge
Municipal and industrial wastewater facilities rely on this pump to transport thick sludge, grit, and other solids-laden waste streams. The pump’s high solids handling capability supports reliable performance in treatment, transfer, and disposal processes where consistent flow and durability are critical.
Fly Ash Slurry Handling at a Thermal Power Plant
Case Study
The Problem
A coal-fired power plant was facing persistent operational issues within its fly ash handling system due to the abrasive nature of the ash slurry. High solids concentration, variable moisture content, and fine particulate material caused rapid wear on pump components, frequent clogging, and repeated system shutdowns. These disruptions led to increased maintenance labor, higher spare parts consumption, and reduced availability of the ash disposal system, directly impacting overall plant efficiency.
The Solution
To address these challenges, the plant replaced its existing centrifugal pumps with the EDDY Pump’s 8-inch HD-8000 slurry pump. The pump was selected for its ability to handle dense, abrasive ash slurries without clogging or requiring excessive dilution. Its heavy-duty internal components and non-clog hydraulic design allowed it to operate effectively under fluctuating ash concentrations while integrating seamlessly into the plant’s existing ash transport infrastructure.
The Result
Following installation, the fly ash handling system showed marked improvements in reliability and consistency. The pump maintained stable flow rates even under peak ash-loading conditions, significantly reducing unplanned shutdowns. Wear life of critical components increased, maintenance intervals were extended, and overall operating costs decreased. The plant achieved more predictable ash disposal operations, supporting continuous power generation with fewer maintenance disruptions.
