Mechanical Seal Retrofit Project at a Large Alumina Plant in Guangxi

A large alumina plant in Guangxi suffered severe failures on the mechanical seals of its two-stage series pumps handling high-solid, high-head slurries. The original seals experienced serious slurry leakage within just a few days to ten days of operation. Inspection revealed heavy wear on the cemented carbide rings. Several other seal manufacturers were engaged but failed to resolve the leakage issue, causing severe disruptions to production. The plant then turned to our company for assistance.

Localized Long-Lasting Sealing Solutions for Hydrometallurgical Autoclaves

Western Mining’s 100,000-ton electrolytic zinc project adopted the world’s most advanced oxygen pressure leaching technology for zinc smelting. Zhejiang Lantian provided mechanical seal systems for its high-pressure reactors, with a service life of up to 10 years. The automated sealing system is equipped with equipment monitoring and functional alarms, making our company one of the earliest domestic suppliers providing localized equipment for hydrometallurgical technologies with stable and reliable performance.
