In highly corrosive and highly abrasive working conditions such as slurry transportation, hydrometallurgy, phosphate chemical industry, lithium salt production, and desulfurization, media containing solid particles can easily cause coupled erosion-corrosion failure of the flow-passing components of wear-resistant chemical pumps, and traditional high-chromium alloy pumps often have insufficient service life. Engineering ceramics such as alumina, zirconia, and silicon carbide are being applied on a large scale in flow-passing components including pump casings, impellers, and liners, among which silicon carbide ceramic pumps have become a popular choice for complex working conditions due to their advantages of high hardness, strong corrosion resistance, and low thermal expansion. The industry design approach has shifted from purely all-ceramic pumps to ceramic-metal composite structures. By adopting replaceable ceramic inserts, silicon carbide ceramic components are arranged at the impeller inlet and high linear velocity wear areas of the blades, combined with a metallic main body frame, which balances wear resistance, corrosion resistance, and impact resistance, while also solving the manufacturing challenges of large pump casings, making it suitable for upgrades of slurry pumps, solids-laden slurry transfer pumps, and other equipment. When facing high solids-content particulate media in lithium salt production, hydrometallurgy, and other processes, a single material can hardly cover all working conditions. Jiangsu Haifa Machinery Manufacturing Co., Ltd. specializes in the R&D of wear-resistant and corrosion-resistant slurry pumps, circulation pumps, vertical sump pumps, as well as API 610/BB/VS chemical process pumps and API 685 magnetic drive pumps, providing non-standard chemical pump selection solutions for highly corrosive and highly abrasive media. In the future, wear-resistant pumps will evolve toward wear simulation calculation, online condition monitoring, and full lifecycle optimization, and composite ceramic structures will become an important development direction for equipment in highly abrasive working conditions.
