The application of alumina ceramics in metering pumps and valves is primarily due to their excellent wear resistance, corrosion resistance, and high precision characteristics.
Core Product Characteristics
1. Wear and Corrosion Resistance: Alumina ceramics (95%-99% purity) have a Rockwell hardness of HRA ≥ 85, and their wear resistance is more than 10 times that of 316L stainless steel, making them especially suitable for conveying environments containing particles or corrosive media. After immersion in strong acid (such as 10% hydrochloric acid) for 30 days, the weight loss is <0.01g, demonstrating excellent chemical stability.
2. Precision Metering and Sealing: The surface finish of ceramic valve plates reaches Ra ≤ 0.1μm, and with micron-level polishing technology, a sealing gap of 0.01mm can be achieved, resulting in extremely low leakage rates. The ceramic impeller adopts a backward-curved design (25°-35° angle), increasing hydraulic efficiency to over 75% and reducing particle impact wear by 40%.
Application Scenarios
1. Chemical/New Energy Fields: Used for conveying slurries containing silicon carbide abrasives or corrosive liquids, ceramic pumps have a leak-free operating time exceeding 8000 hours.
2. Food/Medical Industry: Meeting hygiene standards, ceramic valve plates can be customized for precision components such as tea/water separation faucet valve cores.
3. High-Pressure Valves: Ceramic valve plates maintain sealing performance under high pressure differences; a case study in a mining and beneficiation plant showed a lifespan extension from 3 months to over 1 year.
