Type 28 compressor dry-running gas seals have been the
industry standard since early 1970 for gas-handling
turbomachinery. Utilizing John Crane's patented spiral
groove pattern, 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. |
