Product Description Type 5625P-1
Type 28 compressor dry-running gas seals have been the industry standard since the 1970s 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
