Carbon graphite materials are used extensively vanes, rotors, and end plates in rotary vane pumps pumping both liquids and gases. Carbon graphite rotors are lightweight, saving on energy and withstanding the rubbing of the vane against the end plates. Carbon graphite end plates are pressure-tight and dimensionally stable, so that they can make a close clearance. All three components provide superior lubrication in most environments.
