“ Highest Pressure Non-Contacting, Dry-Running Gas Seal. ”
Type 28 compressor dry-running gas seals have been the industry standard since the early 1980s for gas-handling turbomachinery. Supported by John Crane's patented design features, these seals are non-contacting in operation.
During dynamic operation, the mating ring/seat and primary ring/face maintain a sealing gap of approximately 0.0002 in./5 microns, thereby eliminating wear.
These seals eliminate seal oil contamination and reduce maintenance costs and downtime.
Single, double opposed, and tandem cartridge seals are capable of handling a wide variety of gas sealing applications in the gas collection/transmission, refining, chemical and petrochemical processing industries.
The three seal type designations AT, XP and EXP refer to different design characteristics capable of handling increasing pressure conditions, although final seal selection recommendations are made based on a complete review of application conditions.
