Metallized Carbon Corporation recently announced the availability of custom vanes, rotors and end plates for use in rotary vane pumps pumping both liquids and gases. The carbon-graphite components provide excellent lubrication in most environments and are ideal for pumping liquids with poor lubricating qualities, strong chemicals that attack metals and to pump air, vacuum, combustion products and gasoline vapors.

Metallized Carbon’s carbon-graphite vanes, rotors and end plates are used in such dry-running applications as automotive anti-smog pumps and gasoline vapor pick-up pumps, breathable air pumps and vacuum pumps. In-liquid applications include vending machine beverage pumps, fuel and liquid chemical pumps, and medical liquid pumps. 

Metallized Carbon supplies the carbon-graphite vanes, rotor and end plates to rotary pump and compressor manufacturers and rebuilders. The materials are chemically resistant and are compatible with FDA food and beverage regulations. They have a low wear rate running in both gas atmospheres and low-viscosity liquids.

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. Lightweight carbon-graphite rotors save energy and withstand the rubbing against the vane and the end plates. Carbon-graphite end plates are pressure tight and dimensionally stable to make a close clearance seal with the rotor and vanes. They also withstand the rubbing of both the vanes and rotor.

These materials work best in severe service applications. The components can be supplied to meet custom prints and specifications. For more information, go to www.metcar.com.
