Any Sizes Circular Plate Alumina Ceramic Disc


Description:


High purity alumina ceramic sealing 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 .
