The principal advantage of this seal is the possibility to replace only the wearing faces during overhauls.
They can be supplied in materials such as pure alumina ceramic, solid corrosion resistant tungsten carbide and silicon carbide, normal carbon, metalised carbon, filled PTFE etc. Metallic parts are in stainless steel or in corrosion resistant superalloys and “O” rings can be supplied in any kind of rubber; the seal design is very resilient compared to other seal types reducing the effects of vibration and misalignment of the machine on which it is installed. These features also give it great versatility particularly for heavy duties.
