what are the rotary and stationary main sealing elements:

Rotating seal face and stationary seal ring are main seal elements. Seal rings in ceramic, silicon carbide(sic),carbon,tungsten carbide/TC polished in the range of less than 1 micro on an axial end face run against each other, one rotating with the shaft and the other stationary fixed in the equipment housing.the sealed fluids migrates between the flat faces and make a stable fluid film on the interface. During rotation,the seal face heat up,wear,degrade quickly without a lubricating fluid film between. The sealed fluid creates this thin lubricating film
