Ceramic is commonly used as a mating ring together with carbob-graphite opposite seal face in mechanical seal kits which in turn used in chemical pump applications.
Since Alumina Ceramic Exhibits high hardness, good abrasion resistance & good resistance to acid and mild alkaline solutions. This makes them suitable choice for chemical seal faces. They are used in corrosive environments like acids including Hydro fluroic acids, molten salt solutions, mild to medium alkaline solutions.
D-Tuff Chemical seal faces are manufactured in various sizes and shapes like DA type, L type, T type etc. They are lapped within 20 micron surface finish and polished within 2 light bands and ground to finish sizes as per customer requirements. |
