Type 28EXP

Non-contacting Gas Seal for Turbo Compressors

Type 28EXP: The product for the most challenging and hostile environments with proven and independently audited performance to 425 bar(g). 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"/5 microns, thereby eliminating wear. These seals eliminate seal oil contamination and reduce maintenance costs and downtime. Single, tandem and double seal arrangements are available.
