Carbon and graphite are very high temperature and corrosive resistant materials, which are the most important characteristics for vanes material. The most common applications of vanes made from carbon-graphite are in vacuum pumps, rotary compressors and fuel tanks. Beside that we could find application in food processing equipment, spray paint and printing machinery, petrol pumps and packing machinery. Carbon vanes are suitable for wet and dry running, they are chemically inert and they cannot contaminate pumping media. Because of good self-lubricating properties they are very good for handling liquids with poor lubricating properties like petrol. Depending on working conditions and pumping media vanes could be made of carbon-graphite, metal impregnated carbon graphite or resin bonded graphite.
