Type 28XP
Non-contacting Gas Seal for Turbo Compressors
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 and primary ring 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.
Type 28XP: Possibly the most popular seal in the range today, the Type 28XP builds on the 28AT design and seals medium to high pressures with improved chemical resistance. It can also operate over a wider temperature range and is increasingly the preferred product for large sizes, and for applications requiring slow roll and coast-down where dry gas (very low dew point) conditions and rotational speeds lower than the lift off speed of the gas seal create arduous contacting operation. Type 28XP seals are also available with Carbon LF™ primary ring material for improved friction and wear-resistance for contacting operation in dry gas (very low dew point) conditions.
Features
- Cartridge design
- Unidirectional or bidirectional capability
- Single, double-opposed or tandem configuration
- Robust design with unparalleled field-proven pedigree
Parameters
- Temperature Limits:-220°F to 600°F/-140°C to 315°C, dependent on overall duty conditions
- Pressure Limits:180bar
- Speed Limits:660fps/200m/s
- Size Limits:13.75"/350mm
Design Features
- For high-pressure, high-temperature turbine compressors, only explosion-proof "spring energized seals" can be selected as auxiliary sealing rings.
- Structural component design must undergo rigorous static analysis and optimization.
- The stability of the dynamic pressure effect generated by the dynamic pressure groove and the stiffness-to-leakage ratio must undergo rigorous dynamic analysis and verification tests.
- The isolation sealing structure requires special design and testing to ensure accurate control of nitrogen consumption.
Recommended Applications
- Centrifugal compressors
- Other compressors
- IG compressors
- Turbo compressor machinery
- Natural gas pipeline
- Natural gas/hydrogen refueling stations
- Oil and gas (refineries)
- API 692
- Propylene and ethylene compressor
- Cryogenic
