Diamond Polished High Purity Alumina Ceramic Sealing Valve Disc for Pump
Description of the ceramic sealing valve disc
High purity alumina ceramic sealing valve 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
Specification and ceramic sealing valve 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 50mm
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

Prime benefit of the ceramic sealing valve disc
1. Excellent wear-resistance, over 276 times than stainless steel
2. Exceptional hardness, the hardness is up to 1700MPa
3. Great mechanical properties, hardness, compressive and flexural strength
4. Chemical stability, resistant most of strong acid and alkali
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
Application of ceramic sealing 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.

Packaging proposal and transportation solutions
1. We will keep the ceramic parts inside the inner package to be fixed without moving, then it will prevent them from collision each other, to avoid any cause any chippings during transportation.
2. In addition, the inside of the outer carton will be filled with sufficient protective kinds of stuff.
