Recently, Teflow has successfully completed the manufacturing and inspection of a batch of custom fluorine-lined centrifugal pumps for metallurgical applications. Fully assembled and ready for shipment, these units will soon be put into service for the core electrolyte transfer process in non-ferrous metal smelting, delivering reliable fluid handling solutions with stability, high efficiency and corrosion resistance for hydrometallurgical production lines. This order targets hydrometallurgical processes of copper, nickel, cobalt and other non-ferrous metals, specifically addressing industry challenges including strong electrolyte corrosion, leakage risks and difficulties in continuous operation.

In non-ferrous metal hydrometallurgy, electrolyte transfer is a vital procedure covering leaching, solvent extraction, electrolysis and circulating feeding. Smelting electrolyte is mostly a mixture of high-concentration sulfuric acid and acidic salts, featuring strong corrosivity, high permeability and trace solid particles, creating harsh long-term operating conditions. Conventional transfer pumps made of metal or common plastic are prone to corrosion and rust by acid and alkali media, frequently suffering from pump body perforation, seal leakage, fluctuating flow and equipment jamming or shutdown. Such failures not only cause electrolyte waste and workshop contamination, but also directly impair electrolytic purification accuracy and final product quality, raising production costs from frequent maintenance and equipment replacement. This has become a major bottleneck restricting continuous and refined production for metallurgical enterprises.

Meanwhile, this fluorine-lined centrifugal pump is optimized in hydraulic structure and sealing system to match the process characteristics of low-speed steady flow and continuous circulation of metallurgical electrolyte. It delivers stable flow and consistent head, precisely meeting multi-process requirements such as electrolyte circulation in electrolytic cells, material conveyance and chemical dosing. The pump maintains a uniform and stable electrolyte flow field to improve the efficiency and purity of metal electrolytic purification. Equipped with high-performance mechanical seals, it supports 24/7 non-stop operation. Boasting excellent aging resistance, permeation resistance and sealing performance, it effectively cuts equipment failure rates, greatly extends service life and helps enterprises reduce costs and improve efficiency.

During production and quality control, Teflow strictly adheres to metallurgical equipment standards and conducts rigorous full-process testing for this batch of pumps. Every unit undergoes multiple inspection procedures, including fluoroplastic lining forming, complete pump assembly, pressure testing, air tightness test and corrosion working condition simulation verification, to fully guarantee stability and durability under highly corrosive metallurgical environments. Prior to delivery, staff carry out item-by-item counting, visual re-inspection and professional protective packaging with shockproof, moisture-proof and anti-collision measures, ensuring intact arrival at the project site for rapid commissioning on the production line.

Teflow has long focused on special working conditions in niche sectors including chemical, metallurgical and new energy industries. Centered on scenario-based requirements, the company develops highly adaptable, reliable and durable fluid transfer equipment. Non-ferrous metal smelting is characterized by complex working conditions and stringent equipment requirements. The batch delivery of these dedicated fluorine-lined centrifugal pumps fully demonstrates Teflow’s technical strength and capability to adapt to diverse operating conditions in the field of corrosive medium transfer equipment.
