2. Exceptional hardness, the hardness is up to 1700MPa
3. Chemical stability, resistant most of strong acid and alkali\
4. Great mechanical properties, hardness, compressive and flexural strength
5. Perfect surface contact area ratio:  the value can ensure between 60 ~ 80% 
6. Precise and consistent dimensions every batch via fine grinding
7. Eco-friendly and safe, the material meets FDA, LFGB completely

Specification and ceramic seal disc
1. Material options: 96% alumina, 99% alumina, silicon carbide (SiO2) and Silicon nitride (Si3N4)
2. Working surface roughness: fine polishing better than Ra0.3, diamond polishing better than Ra0.1
3. Dimension: the max. outer diameter up to 200mm
4. Other parameters: flatness to be 0.002mm, perpendicularity: 0.005mm, Parallelism : 0.002mm
4. Nominal tolerance: size less than 10mm with 0.10mm, size over than 10mm with 1% of dimensions
5. Precision process available: polishing, fine grinding, CNC machining

Description of the ceramic seal disc
High purity alumina ceramic seal disc for the pump seal has been recognized for its safe, outstanding properties and precise operation, thereby creating a perfect sealing effect. Furthermore, aluminum oxide ceramic (alumina) is a very cost-effective material, so alumina ceramic sealing discs have been widely used. With comparison with traditional seal disc,  it can work smoothly even if after 500,000 cycles or higher due to its unmatched wear resistance and exceptional mechanical strength. 
As the ceramic sealing disc is a key component in oil, water, gas sealing system, we always ensure that we manufacture best-quality products through strict quality control in every process, we introduced KPI into our manufacturing flow chart and keep all batches with consistent dimensions. 
With over 15 years of manufacturing experience for ceramic sealing discs, we have been supplying a variety of standard components, also we support various customized needs per your technical drawings, specification, or practical samples.
If you are looking for a quality manufacturer for ceramic sealing discs, please get through with us. We do believe you will find it's a wise choice

The typical application of ceramic seal disc
Ceramic seal discs are widely used in a variety of water faucet, water tap, sanitary sealing system, regulating system,  sealing valves, water /oil/gas pump, and so on.
