Guangxi Jinchuan Nonferrous Metals HRS high-temperature concentrated sulfuric acid vertical submerged pump project | Fangchenggang, Guangxi

Application scenario: Jinchuan Group 400,000-ton copper supporting 1.6 million-ton sulfuric acid production line, HRS low-temperature waste heat recovery acid plant core equipment. Transporting 220°C, 99.3%-99.7% concentrated sulfuric acid (density 1840 kg/m³), extreme conditions of strong corrosion, high temperature, and high density, requiring 8,000 hours annual continuous operation without major overhaul.


Solution content: GLSP450-17 API VS4 vertical submerged pump (1,340 m³/h, head 17 m, efficiency 82%, equipped with 160 kW motor), special corrosion-resistant alloy flow parts, CFD optimized flow channel, P74 independent closed flushing cooling sealing system, fully compliant with API chemical pump standards, full factory testing.


Project results: Core critical equipment of acid production section, ensuring stable continuous transportation of high-temperature concentrated sulfuric acid for 8,000 hours, eliminating leakage and shutdown risks.
