• Rotary vanes made of MarathonCarb from Schunk Carbon Technology

Rotary Vanes

When it comes to extending service intervals of dry-running vacuum pumps, our rotary vanes made of MarathonCarb™ are the first choice. MarathonCarb™ is a self-lubricating carbon-based vane material that minimizes wear of the sliding flanks (scour) as well as vertical wear and does not swell when exposed to humidity.  

Benefit from these advantages:

  • Low wear, therefore up to three times longer service life 
  • High dimensional stability, even in high humidity
  • Intensive advice on the selection of material variants 

In addition to that, Schunk offers materials (including CFRP) for lubricated rotary vane pumps and compressors.
