Double Static Metal Bellows Seal
Type C seal of AP1682 arrangement 3/(3CW-FF) Mating ring at medium side is restricted bi-directionally, which can overcome pressure fluctuation and vacuum. Bellows will be stationary during operation, so they are excellent under the working conditions of high-speed and large shaft diameter usually used for high temperature equipment, eg hydrogenation feed pump and hydraulic turbine in a refinery.
