Aerospace Seals for Pumps and Accessories
O-Ring Face Seals
The O-ring TFE face seal is designed for applications in which heat and size requirements demand special engineering and manufacturing expertise to produce a high quality, positive face seal. They are used for sealing gases and oils where the temperature range exceeds that for an elastomeric secondary seal. Typical uses are for gas turbines in airplanes, helicopters, missiles, space vehicles and ground support equipment.
Teflon® Face Seals
Bellows Seals
The Metal Bellows Seal is designed for use in extreme temperatures and for chemical applications where elastomers are not practical. They are ideal for high temperature fuels, oils and gases, and for extremely low temperatures such as liquid oxygen refrigeration systems.
Shallow Hydropads Seals
Patented and production proven technology capable of eliminating oil leakage and extending seal MTBF.
• Non-Contacting: Creates and maintains a lubricating film (cushion of air) that the seal face rides on.
• Virtually Zero Leakage: High pressure “air barrier” eliminates oil leakage across the sealing interface.
• Reduced Heat Generation: By as much as 80%-90% over that of conventional seal designs.
• Extended Seal Life: Non-contacting mode results in very low wear and dramatically increases seal life.
Xcentra® Seals
Mating Rings
Segmented Seals
Multiple ring segmented seals are designed with segmented rings, to operate in contact with the shaft throughout the life of the seal. Since no elastomers are used, the Type-6 allows for an exceptionally wide range of temperatures, from cryogenic of -400 °F to as hot as 1600 °F.
Segmented seals are used for sealing cryogens or hot gases from bearings and other mechanisms in gas turbines, interstage compressors, refrigeration compressors, aircraft cabin compressors, missiles, jet engines and superchargers. Compact construction simplifies installation in applications where space is limited. The Type-6 Seal is recommended where lower leakage rates are desirable and contact with the shaft is acceptable.
