Carbon graphite materials are used extensively for vanes , rotors and end plates in rotary vane pumps pumping
both liquids and gases. Carbon graphite vanes can withstand the rubbing of the vane tip against the housing bore
and the rubbing of the side of the vane against the slots in the rotor. Carbon Graphite rotors are light in weight to
save energy and can also withstand the rubbing of the vane against the end plates.
Carbon graphite vanes , rotors and end plates are used for pumping liquids with poor
lubrication properties (low viscosity) such as water. gasoline and beverages. They are also used for
pumping strong chemicals that attack metals.
Carbon Graphite Vanes , rotors and end plates are also used to pump gases such as air , vacuum ,
combustion products and gasoline vapors.
Graphic Products supplies carbon graphite vanes , rotor , and end plates to rotary pump and compressor manufacture
and rebuilders. The Vanes , rotors , and end plates can be supplied to customer prints and specifications.
