Silicon Carbide Mechanical Seals

Mechanical seal faces must operate in challenging conditions, including high speeds, temperatures, and pressures, while remaining resistant to corrosion and wear. Technical ceramics feature the optimal toughness, stiffness, flexural strength, hardness, and corrosion resistance for mechanical seal faces. They are particularly well-suited for dry gas seal assemblies that require low deflection from high speeds and low thermal expansion from high temperatures.

Silicon carbide faces in mechanical seal assemblies result in improved performance, increased seal life, lower maintenance costs, and lower running costs for rotating equipment such as turbines, compressors, and centrifugal pumps. CoorsTek seal faces help reduce the possibility of leakage and catastrophic failure to safeguard the environment from the risk of fugitive emissions. They also lower energy consumption with reduced friction on startup and shutdown, as well as reduced wear and erosion during operation. CoorsTek seal faces are exceptionally durable and help increase the mean time between failures, resulting in greater productivity and lower total cost of ownership for processing equipment.
