Learn Why the 2-Inch EDDY Pump Delivers Higher Production and More Uptime
The EDDY Pump 2-Inch Slurry Pump is engineered specifically for high-solids, abrasive pumping where small pumps typically clog, lose efficiency, or fail prematurely. Built around EDDY Pump’s patented open rotor technology, this pump moves slurry with up to 70 percent solids by weight while maintaining stable flow rates from 50 to 390 GPM. Unlike conventional centrifugal or vortex pumps that rely on tight clearances, the ultra-recessed adjustable rotor allows solids up to 1.75 inches (depending on solid type and application) to pass through without plugging, even as material size and consistency fluctuate.
This ability to pass large solids directly translates into higher production rates and reduced downtime. The pump continues to operate in debris-laden, viscous, and high-specific-gravity slurries, where frequent shutdowns are common with traditional designs. By eliminating internal clog points and reducing wear concentration, the 2-inch EDDY Pump maintains uptime, lowers maintenance frequency, and supports continuous industrial operation in demanding environments such as mining, wastewater, dredging, and process industries.

Food Processing Waste Stream Management – Our Case Study
The Problem
The facility generated dense organic waste slurries containing peels, pulp, fats, skins, and fibrous byproducts from multiple processing lines. These materials varied in consistency throughout the day and repeatedly caused conventional pumps to clog or lose prime. Frequent shutdowns were required for manual cleaning, increasing labor costs and disrupting production schedules, especially during peak throughput periods.
The Solution
An EDDY Pump 2-inch slurry pump was deployed to move waste slurry from floor collection points and sumps to centralized treatment and digestion tanks. The EDDY Pump open rotor design, with wide internal clearances, allowed fibrous and stringy materials to pass through without plugging. The pump maintained stable flow even as solids concentration and viscosity fluctuated, eliminating the need for constant operator intervention.
The Result
Unplanned stoppages were reduced, and waste transfer became a continuous, predictable process. Maintenance frequency dropped, labor demands for cleanup decreased, and overall plant uptime improved. The facility gained better control over waste handling while supporting higher production rates without increasing system complexity.

Frequently Asked Questions
What materials can the 2-Inch EDDY Pump slurry pump handle?
The 2-inch EDDY Pump slurry pump is designed to move abrasive slurries, sludge, grit, sand mixtures, drilling mud, organic waste, and other high solids materials. Its open rotor design allows it to handle variable consistency fluids that would clog or wear out conventional pumps.
How much solids can this pump handle?
This pump can handle slurry with solids concentrations ranging from approximately 40 to 70 percent by weight, depending on the material characteristics. This makes it suitable for applications where conventional centrifugal pumps lose efficiency or fail entirely.
What is the maximum solids size the 2-Inch pump can pass?
The 2-inch slurry pump can pass solids up to approximately 1.75 inches in diameter. This capability reduces the need for upstream screening and minimizes the risk of clogging in debris-laden applications.
What flow rate and head range does this pump operate in?
The pump operates within a flow range of roughly 50 to 390 GPM, with head capability up to 90 feet. Actual performance depends on slurry density, solids concentration, and discharge conditions.
How does the EDDY Pump design differ from a standard centrifugal pump?
Unlike centrifugal pumps that rely on tight clearances and high velocity, the EDDY Pump uses a patented open rotor design that creates a powerful vortex. This allows solids to pass through freely while maintaining performance in abrasive and high viscosity conditions.
Can the pump be installed vertically or horizontally?
Yes, the 2-inch EDDY Pump slurry pump can be installed in either vertical or horizontal orientations. This flexibility allows it to be integrated into sumps, pits, portable skids, or fixed industrial systems.
What materials are available for wear components?
Wear components such as the rotor and volute are available in high chrome, ductile iron, stainless steel, duplex stainless, and other custom alloys. Material selection is based on abrasion level, corrosion potential, and operating environment.
How does the seal system perform in abrasive applications?
The pump is equipped with a dual mechanical seal system using tungsten carbide or silicon carbide faces, along with a self-contained seal flushing system. This design improves seal life and reliability when pumping abrasive slurries.
What maintenance is required for this pump?
Routine maintenance typically involves periodic inspection of wear components and seals, based on operating hours and material abrasiveness. Due to the non-clog design, maintenance frequency is generally lower than with conventional slurry pumps. Read More
Is a custom pump curve available for specific applications?
Yes, custom pump curves can be developed based on the actual slurry being pumped, including solids concentration, particle size, and specific gravity. This ensures accurate sizing and reliable performance for each application.
