Carbon Graphite Rotors & Vanes

St. Marys Carbon manufactures a variety of different sizes and types of carbon graphite rotors & vanes. We will develop a complete set of rotors & vanes for you or we will simply custom-develop vanes to fit any of your specialty rotors made from other materials. Our rotors & vanes provide lubrication without the use of oil or any other contaminating lubricants, which makes them ideal for your dry-running or sanitary environments.

Key Advantages of St. Marys Carbon Rotors and Vanes:

  • Dry-Running / Oil-lessOur rotors and vanes are self-lubricating, meaning that a separate lubricant is not required, which allows them to be used in not only dry-running but also sanitary applications.
  • Low Friction / Wear – The self-lubricating properties of our rotors and vanes will greatly reduce the amount of friction and wear during operation, significantly reducing maintenance time, replacement and equipment damage.
  • High Thermal Conductivity – Our rotor and vane materials allow for heat exchange, which will prevent overheating and most importantly will not cause damage to your equipment.
  • Stability at High Temperatures – Our proprietary mix of carbon graphite is able to withstand extreme temperatures, which allows our rotors and vanes to be used in a variety of harsh environments while still maintaining performance and increasing your equipment’s uptime.
  • Anti-Welding/Melting: As our rotors and vanes can withstand high temperatures, they are resistant to melting or welding to your equipment during operation, allowing your equipment to run longer and perform better.
  • Oxidation-Resistant: Our proprietary mix of carbon graphite resists chemical degradation of the surface material, allowing our rotors and vanes to last longer even in harsh environments.

Custom Solutions

If you require a customized solution, we can manufacture our carbon graphite rotors and vanes to your specific requirements. We develop our own proprietary grades and manufacture each product in-house, so we will work closely with you to create a carbon graphite product that is right for you.
