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.
