What it is:
Tailings pipelines transport thick, abrasive slurry from processing plants to containment areas for storage or dewatering.
Challenges:
High solids and long-distance pumping create severe wear and high energy demands. Any breakdown leads to costly production interruptions.
Solution:
Hevvy/Toyo’s robust slurry pumps with large internal clearances and wear-resistant materials deliver continuous, efficient tailings transport with reduced maintenance and lower lifecycle costs.
Barge unloading in municipal wastewater operations typically involves transferring sludge, grit, or biosolids from transport barges to treatment or storage facilities. The process requires high-capacity pumping systems that can handle thick, abrasive, or viscous material efficiently.
Challenges:
Barge contents often settle during transport, creating dense, compacted sludge that’s difficult to mobilize. Standard pumps experience suction loss, clogging, and wear when handling high solids or abrasive material. Setup flexibility and mobility are also critical in temporary or remote unloading sites.
=Solution:
Hevvy/Toyo’s submersible dredge and slurry pumps excel in barge unloading. Their agitator systems re-suspend solids for complete barge evacuation, while wear-resistant materials withstand abrasive conditions. Compact and portable, they can be quickly deployed and moved between sites — providing reliable, high-throughput pumping for municipal sludge and solids transfer operations.
Hog waste lagoons store liquid manure and wastewater from livestock operations before treatment or land application. These lagoons contain a thick slurry of solids, fats, and organic matter that must be agitated and transferred regularly to prevent buildup and environmental hazards.
Challenges:
Hog waste is dense, corrosive, and prone to stratification, forming thick sludge layers at the bottom that are difficult to mobilize. Gas generation and solids accumulation can lead to odor, safety, and compliance issues. Pumps must operate reliably in abrasive, corrosive, and biologically active conditions.
Solution:
Hevvy/Toyo’s heavy-duty agitator pumps are ideal for lagoon agitation and transfer. Their high-chrome wet ends, mechanical seal protection, and robust motors handle corrosive, high-solid waste with ease. The powerful agitator keeps sludge suspended for full lagoon turnover, enabling efficient pumping and reducing the need for manual or mechanical dredging.
Wet scrubbers remove particulates and gases from steel plant exhaust systems by washing them with water or chemical solutions. The collected slurry, containing dust, metal oxides, and chemical residues, settles in sumps or collection tanks that must be regularly emptied to maintain scrubber performance.
Challenges:
Scrubber slurries are abrasive, corrosive, and often have high solids concentrations that lead to rapid erosion of impellers and volutes. Chemical additives can attack seals and metallic components, while variable slurry densities challenge consistent pumping.
Solution:
Hevvy/Toyo’s corrosion- and abrasion-resistant pumps handle aggressive scrubber slurry with ease. Available in high-chrome, stainless steel, or elastomer-lined configurations, they resist both chemical and mechanical attack. Their recessed impeller and agitator systems ensure consistent flow and minimal downtime, making them ideal for continuous scrubber sump operation.
Sand dredging involves excavating and transporting sand from riverbeds, lakes, harbors, or coastal zones for land reclamation, construction, or navigational purposes. It’s one of the most common dredging operations, requiring continuous, high-volume material movement under variable conditions.
Challenges:
Sand is highly abrasive and can rapidly wear down impellers, liners, and bearings. Variable density and particle size cause inconsistent flow and high power consumption. Cavitation, clogging, and maintenance downtime are frequent issues, especially in shallow or sandy environments.
Solution:
Hevvy/Toyo dredge pumps are engineered for maximum durability in abrasive, high-solid environments. Their agitator technology keeps sand suspended, while thick high-chrome construction and replaceable liners extend pump life. Compact submersible options minimize priming issues and simplify deployment for both portable and fixed dredging setups.
Sand separation is a critical step in oil and gas production to remove sand and other particulates from produced fluids. Whether upstream in separators or downstream in treatment systems, effective sand removal protects equipment, reduces erosion, and maintains flow assurance.
Challenges:
Separated sand tends to settle and compact in sumps and tanks, forming abrasive layers that are difficult to remove. High solids loading quickly wears out conventional pumps, while intermittent flow can lead to blockages or inefficient operation.
Solution:
Hevvy/Toyo pumps with recessed impeller designs and agitators are ideal for handling abrasive, sand-laden fluids. They maintain solids in suspension, preventing settling and ensuring consistent transfer. With options for hard-metal wet ends and explosion-proof motors, these pumps deliver safe, durable performance in demanding sand-handling environments.
