Vertical Submerged Pumps In Industrial Sedimentation Tank Slurry Transportation

Application Scenarios

Vertical submerged pumps are widely used in chemical, power, coal, metallurgical, and other industrial plants, serving slag slurry, mud, and waste residue transportation for large-scale sedimentation tanks, coal slurry tanks, slurry storage tanks, and wastewater regulating tanks. They are key supporting equipment for industrial sewage treatment, slurry circulation, and waste residue cleaning systems.

Working Conditions

Industrial production continuously generates sludge-containing and slag-containing wastewater. Sedimentation tanks accumulate thick mud and fine waste residues with high solid content, high viscosity, fast sedimentation speed, and easy compaction. Traditional horizontal pumps and submersible pumps have obvious adaptability defects: large floor space, complicated installation, matching priming and drainage facilities, and high maintenance difficulty. Narrow flow passages easily cause blockage by viscous mud and fine residues, leading to frequent shutdown failures. Manual cleaning of tank sediment interrupts production progress severely, and conventional equipment leaves massive residues, resulting in repeated siltation and restricting stable operation of industrial sewage circulation systems.

Equipment Selection and Installation

Vertical long-shaft submerged slurry pumps are specially selected for industrial sedimentation tank conditions. Adopting large-channel non-blocking design and vertical layout, the pump body extends to the tank bottom while motors and transmission components are arranged above the liquid surface, fundamentally eliminating motor flooding, corrosion, and electric leakage risks and improving operational safety. The pump requires no bottom valve or pre-filling water for priming and realizes automatic slurry suction, perfectly adapting to high-viscosity, high-solid-content, and easily compacted industrial mud. Featuring compact structure and small floor space far superior to traditional horizontal pumps, it adapts to compact industrial installation environments and saves infrastructure investment by eliminating the need for additional priming and water supply facilities.

Operation Effects

The equipment supports 24-hour uninterrupted stable operation, efficiently conveying coal slurry, chemical slag, and sewage waste residues. The large-channel design completely solves blockage problems caused by fine residues and viscous mud with stable flow and continuous operation, significantly improving industrial slurry treatment efficiency. Fully sealed zero-leakage operation and wear-resistant, corrosion-resistant flow components greatly extend service life, reduce equipment replacement frequency and failure times, and save substantial costs on equipment procurement, operation, and labor. Real-time removal of bottom sediment thoroughly eliminates repeated siltation and incomplete cleaning problems, ensuring closed-loop stable operation of industrial sewage treatment and slurry circulation production lines and supporting continuous industrial production.

Application Summary

Vertical submerged slurry pumps are precisely tailored for slurry transportation of various industrial sedimentation tanks, slurry storage tanks, and sewage tanks. With prominent advantages of priming-free operation, anti-blocking, zero leakage, small floor space, simple maintenance, and stable performance, they efficiently solve treatment difficulties of viscous industrial slurry, compacted residue, and high-concentration wastewater. Widely applicable to chemical, power, coal, metallurgical and other industries, the pumps deliver excellent universality and practicality.
