Properties of Silicon Carbide Mechanical Seal


  1. Chemical Resistance:
    Our seals are crafted from silicon carbide, a material renowned for its excellent chemical resistance. This allows them to operate stably in the presence of most chemical media, ensuring long-term performance in demanding industrial settings.

  2. High Hardness & Abrasion Resistance:
    With its extremely high hardness, silicon carbide stands up to wear and tear, providing a long service life even in high-abrasion applications.

  3. Low Friction Coefficient:
    Pairing silicon carbide with silicon carbide or carbon-graphite results in a low friction coefficient, making our seals ideal for applications requiring minimal friction.

  4. High Temperature Stability:
    Silicon carbide's high temperature stability ensures that our seals maintain consistent performance in high-temperature environments, making them perfect for mechanical sealing in such conditions.

  5. Versatile Media Compatibility:
    Suitable for sealing a wide range of media, including solids-laden and corrosive fluids, our Silicon Carbide Mechanical Seals offer unmatched versatility and applicability.

  6. Exceptional Stability:
    The inherent stability of silicon carbide ensures that our seals remain effective over time, resisting external influences and maintaining a consistent seal.


Applications of Silicon Carbide Mechanical Seal


  1. Pure SSiC Rings for Corrosive Media:
    Our seals feature a pair of pure Silicon Carbide (SSiC) rings for the rotating and stationary components. This configuration is ideal for applications involving highly corrosive media, providing exceptional resistance and ensuring long-term durability.

  2. Hybrid SSiC and Sic+C Rings for Vaporizable Media:
    For applications where media is prone to vaporization, we offer a configuration with one SSiC ring and one ring made of Silicon Carbide with Carbon (Sic+C). This combination offers enhanced performance in vaporizable media, ensuring a reliable seal under such conditions.
