Where This Pump Performs
Mining and Mineral Processing
This booster pump is widely used in mining operations to move high-density slurries, tailings, and abrasive materials over long distances. Its ability to handle large solids and high solids concentration supports continuous production while reducing wear and downtime in harsh mine environments.
Sand and Aggregate
In sand pits, quarries, and aggregate processing facilities, the pump supports material transfer, stockpile feeding, and pipeline boosting. The non-clog design ensures stable flow when handling coarse sand, gravel, and mixed debris common in aggregate operations.
Oil and Gas
The pump is applied in drilling mud circulation, cuttings transport, and waste slurry handling at upstream and midstream sites. Its high-torque diesel drive and solids-handling capability enable reliable operation in remote locations with challenging fluid characteristics.
Dredging and Marine Construction
Used as a booster pump in dredging pipelines, this unit increases discharge distance and production rates. It performs effectively in sediment-removal, channel-maintenance, and land-reclamation projects that require heavy slurry transport.
Chemical and Industrial Processing
The pump supports transfer of viscous, abrasive, and chemically aggressive slurries in industrial processing environments. Material options and mechanical sealing systems help ensure performance and durability in continuous-duty chemical applications.
Paper and Pulp
In paper mills and pulp-processing plants, pumps transport fibrous slurries, waste streams, and residual solids. Its non-clogging design reduces blockages from stringy materials while maintaining consistent flow rates.
Fly Ash and Coal Ash
The pump is well-suited for ash-handling systems at power generation facilities, efficiently moving abrasive fly ash and bottom ash slurries. High solids capability helps reduce water usage while supporting long-distance slurry transport.
Wastewater and Sludge Handling
The pump is used in industrial wastewater treatment for transferring thick sludge, grit, and settled solids. Its ability to handle large particles and variable solids concentrations makes it effective for demanding sludge pumping applications.
Mid-Pipeline Booster Support for Long Distance Mine Tailings Transport
Case Study
Problem
The mining operation was required to transport dense tailings slurry over an extended pipeline with varying elevations and long horizontal runs. As discharge distance increased, friction losses reduced pipeline pressure and slurry velocity, causing solids to settle in low-velocity zones. This resulted in frequent line flushing, accelerated pipe wear, and production interruptions, reducing overall plant efficiency.
Solution
The EDDY Pump’s 12-inch diesel powered direct drive booster pump was strategically installed at a mid-line location to provide additional head and stabilize system pressure. The booster operated in series with the primary pump, increasing discharge energy without forcing the main pump to run outside its optimal range. Its non-clog design and high solids-handling capability enabled it to process large particles and dense slurry consistently while maintaining target pipeline velocities.
Result
With the booster pump in operation, slurry velocity remained uniform across the entire pipeline, eliminating settling and reducing the need for manual intervention. The system achieved higher, more consistent throughput, minimized wear on pipelines and pump components, and enabled uninterrupted long-distance tailings transport, improving overall operational reliability and cost efficiency.

Frequently Asked Questions
What is the primary role of this booster pump in a pumping system?
This booster pump is designed to increase head and maintain slurry velocity within long or complex pipeline systems. It operates in series with a primary pump to compensate for friction losses, elevation changes, and extended discharge distances without overloading the main pump.
What types of materials can this booster pump handle?
The pump is built to handle high-density slurries, including mine tailings, sand, gravel, ash, drilling mud, sludge, and other abrasive or debris-laden materials. Its non-clogging design allows it to pass large solids while maintaining consistent flow.
How does a booster pump differ from a primary dredge or slurry pump?
A primary pump initiates material movement from the source, while a booster pump adds energy downstream to maintain pressure and velocity. The booster does not replace the main pump but supports it by extending discharge distance and improving overall system efficiency.
Can this booster pump handle high solids concentrations?
Yes, the pump is engineered to operate at slurry concentrations of approximately 40-70% solids. This capability allows operators to move more material with less water, improving production efficiency and reducing water usage.
What size solids can the pump handle without clogging?
The 12-inch booster pump can pass solids up to approximately 11 inches in diameter. This reduces the risk of blockages and allows reliable operation when pumping coarse or mixed material.
Is this pump suitable for continuous operation?
The pump is designed for heavy-duty continuous operation in demanding environments. Its robust construction, low operating speed, and abrasion-resistant materials enable extended runtimes with reduced wear and maintenance requirements.
What power source does this booster pump use?
The unit is powered by a 700 HP diesel engine with a direct-drive configuration. This setup provides high torque and reliable performance, especially in remote locations where electrical power is limited or unavailable.
How is the booster pump integrated into an existing pipeline system?
The booster pump is installed in line along the discharge pipeline at a location determined by hydraulic calculations. It operates in series with the primary pump to restore pressure and maintain slurry velocity across long distances or elevation changes.
Does the pump require a custom pump curve for slurry applications?
Yes, the standard pump curve is based on water performance. Actual slurry characteristics such as solids concentration, particle size, density, and pipeline layout affect performance. A custom pump curve ensures accurate sizing and optimal efficiency for the specific application.
What industries commonly use this type of booster pump?
This booster pump is widely used in mining, dredging, sand and aggregate, power generation, oil and gas, industrial processing, wastewater treatment, and ash handling applications where long-distance slurry transport is required.
