Metal-Clad Alumina Ceramic Pump is a composite fluid conveying equipment that combines a metal shell with an alumina ceramic lining, designed specifically for handling highly corrosive and highly abrasive media. Compared with traditional all-metal pumps or ordinary ceramic pumps, this product enhances mechanical strength through a metal outer shell structure, while utilizing the high hardness and chemical corrosion resistance of alumina ceramics to significantly extend service life. Its core advantage is that it simultaneously solves the industry pain points of metal pumps being prone to corrosion and ceramic pumps being prone to brittle cracking. Metal-Clad Alumina Ceramic Pump adopts a double-layer composite structure: the outer layer is a pressure-resistant metal shell (such as stainless steel or titanium alloy), and the inner layer is a high-purity alumina ceramic (Al₂O₃ content ≥ 95%) lining. The alumina ceramic lining is tightly combined with the metal shell through precision machining to form a seamless protective layer that can withstand strong acid and alkali environments with a pH value of 0-14, and resist erosion by solid particles with a particle size of ≤1mm. The equipment has an operating temperature range of -20℃ to 250℃ and a maximum working pressure of 2.5MPa. It is suitable for conveying media such as sulfuric acid, hydrochloric acid, sodium hydroxide solution and slurry. Its modular design supports rapid replacement of ceramic linings and reduces maintenance costs. The product is widely used in processes such as hydrometallurgy, flue gas desulfurization, electroplating wastewater treatment and semiconductor wafer cleaning, meeting the needs of continuous and stable operation under high corrosion and high wear conditions.
