Seal Rings

Mechanical seal rings are used to seal the clearance between the rotating shaft and the stationary housing in equipment such as pumps and mixers, so that liquid can not leak out through this clearance. These sealing mechanisms are often referred to as “shaft seals” or “pump seals”. Metallized Carbon Corporation manufactures the mechanical “Primary Rings” or “CarbonGraphite Wear Faces” used in many of today’s most sophisticated and reliable mechanical seals for industrial, aerospace and military applications. These mechanical seal assemblies usually consist of a primary seal ring manufactured using carbon graphite materials, a counter face ring, secondary (O-ring) seal rings, springs, fasteners, and a metal housing. Mechanical seal assemblies are also used to seal gases in high speed compressors. These “dry gas seals” are double mechanical seals that utilize a controlled “barrier gas” and spiral grooves in the counter face which provide aerodynamic lift off or gas lubrication between the seal faces. Mechanical seal primary rings can be supplied to customer drawings and specifications. The rings can be supplied plain, shrink fitted or cemented in metal retaining rings. Metcar mechanical seal rings can also be supplied with the sealing face lapped flat to one helium light band.
