Mechanical Seals come in a wide range of designs however the most important factor when determining how long a seal is going to last, is deciding on the right seal face materials.The most common types of seal faces are: Carbon, Ceramic, Silicon Carbide, Tungsten Carbide, GFPTFE (glass filled PTFE). Thus Rota-Tech provide wide range of Mechanical Seal faces as primary sealing member in Mechanical seal and rotary unions with best quality.
Ceramic Seal faces have the property of good sealing properties,resistant-high-temperature,resistant-corrosion, and resistant-wearing. Due to it’s hardness, Ceramic (%99.5) sealing materials offer excellent wear characteristics. It is a chemically inert marterial and can be applied to nearly any product. However ceramic can not handle thermal shocks.Ceramic Seal Rings is the best seal face material for highly corrosive chemical services.We supply the High Alumina ceramic materials.
Tungsten carbide is widely used in many applications requiring high strength, high resistance and hardness. Tungsten carbide; nickel-bonded and cobalt-bonded. Tungsten carbide with a high modulus of elasticity that prevents surface deformation is the ideal solution for high pressure applications.
