Rotors and Vanes Designed for Efficient Operation and Long Service Life
Rotors and vanes must support efficient operation, controlled wear, and long service life in pumps, compressors, and vacuum systems. Consistent performance depends on handling varying pressures, speeds, temperatures, and environments — helping reduce maintenance in continuous-duty applications.
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.
ENVIRONMENT, OPERATING CONDITIONS & APPLICATIONS
DRY-RUNNING / OIL-LESS
Enable dry-running, oil-less operation to reduce failure rates and simplify system design.
HIGH TEMPERATURE STABILITY
Maintain strength and operational stability at elevated temperatures in continuous-duty equipment.
HIGH THERMAL CONDUCTIVITY
Dissipate heat efficiently to reduce overheating and protect system performance.
