C03 Mechanical Seal

image

The C03 Mechanical Seal is a reliable metal bellows seal designed for industrial applications requiring stable performance and good resistance to chemical exposure. It features an elastomer-free bellows construction combined with an encapsulated PTFE secondary seal, ensuring effective sealing in moderately demanding environments.
With operating limits up to 2 MPa pressure, speeds up to 20 m/s, and temperatures ranging from -30°C to +204°C, the C03 is suitable for a wide range of industrial processes. Its flexible metal bellows design allows it to handle thermal expansion and mechanical stress efficiently while maintaining sealing integrity.
Manufactured from high-quality materials such as silicon carbide, carbon, and advanced alloys including AM350, Inconel 718, Titanium, and Hastelloy-C, the C03 delivers reliable performance, corrosion resistance, and long service life.
