Ash Slurry Management for Continuous Power Plant Operations – Case Study
Challenge
A major coal-fired power plant faced persistent operational disruptions due to its conventional centrifugal pumps failing to handle highly abrasive fly ash and bottom ash slurry. Frequent seal failures, impeller erosion, and clogging caused unplanned shutdowns, resulting in costly maintenance interventions and reduced plant efficiency. Additionally, inconsistent ash transport led to compliance challenges with environmental discharge regulations, putting pressure on the facility’s operational reliability and uptime.
Solution
To address these challenges, the plant replaced its existing ash handling system with the EDDY Pump’s 12-Inch 700 HP Self-Priming Pump. Designed for extreme slurry conditions, the pump’s patented non-clog rotor and high-wear-resistant materials allowed it to handle up to 70% solids content and pass large abrasive particles without blockage. Its dual mechanical seal system and abrasion-resistant components significantly minimized wear, while the pump’s high flow capacity ensured continuous ash transport over extended discharge distances.
Result
The upgraded system enabled uninterrupted ash removal operations, eliminating unplanned downtime and reducing annual maintenance interventions by over 35%. The improved reliability not only enhanced plant efficiency and output but also ensured consistent environmental compliance. The power plant achieved a more stable operational cycle, optimized resource utilization, and significantly lowered the total cost of ownership over the long term.

This allows for higher uptime, lower maintenance, and superior performance in abrasive or viscous pumping environments.
Can this high-power slurry pump be customized to match specific project requirements?
Yes. The 12-Inch self-priming pump can be configured with different materials of construction (such as High Chrome, Duplex Stainless, or Ductile Iron), custom pump curves, and mounting options (skid or trailer) to match your site conditions, slurry characteristics, and performance requirements.
What is the maximum pumping capacity and distance achievable with this unit?
The diesel self-priming pump delivers flow rates of up to 7,300 GPM with a head range of up to 180 ft, making it capable of transporting slurry over long discharge distances. For extended pipelines, booster stations can be integrated to increase range and maintain flow efficiency.
How does the heavy-duty self-priming pump perform in corrosive or chemically aggressive environments?
The diesel self-priming pump is engineered with materials like Duplex Stainless Steel and High Chrome alloys that resist corrosion, low pH, and chemical attack. This makes it ideal for chemical processing, wastewater treatment, and other harsh industrial applications.
What kind of maintenance does the Tier 4 diesel engine pump require?
Thanks to its non-clog design and abrasion-resistant components, the pump requires significantly less maintenance than conventional alternatives. Routine checks of seals, bearings, and rotor wear are recommended. EDDY Pump provides comprehensive service support and ensures spare parts availability.
Can the 12-inch 700 HP diesel self-priming slurry pump handle continuous 24/7 operation?
Yes. The unit is specifically designed for continuous-duty industrial applications. Its robust construction, advanced seal technology, and efficient cooling system enable round-the-clock operation even under demanding load conditions.
What equipment is required to operate the 12-inch self-priming pump effectively?
The 700 HP self-priming pump typically pairs with a 700 HP Tier-4 diesel engine or equivalent power unit, as well as compatible suction and discharge piping. Control and monitoring systems are recommended for optimal operation and protection.
Is the 12-inch 700 HP self-priming diesel slurry pump suitable for mobile or remote-site applications?
Absolutely. The system can be supplied as a trailer-mounted unit for rapid deployment across multiple job sites or as a skid-mounted solution for fixed installations. This flexibility makes it ideal for field operations in mining, dredging, and oilfield environments.
