Compressor Pump Single Spring Mechanical Seal


Compressor Pump Single Spring Mechanical Seal


Burgmann, a global leader in sealing solutions, presents its high-performance Single Spring Mechanical Seal specifically engineered for compressor pumps in oil & gas, petrochemical, and industrial applications. Designed for reliability in demanding conditions, this seal features a robust single-spring mechanism that maintains optimal face loading even under variable pressures and shaft movements.

Key Advantages for Compressor Applications:
Gas & Process Compatibility – Handles dry-running, high-speed, and sour gas environments
Wide Material Selection – SiC, tungsten carbide, and corrosion-resistant alloys (Hastelloy®, Inconel®)
Reduced Maintenance – Self-adjusting spring design minimizes wear and extends service life
API 682 & ISO 21049 Compliance – Meets strict industry standards for compressor reliability

Ideal for centrifugal, reciprocating, and screw compressors, Burgmann’s seals ensure leak-free operation in critical processes. Custom configurations available for high-pressure or extreme-temperature duties.

Key Features- Cost-effective
- Easy installation
- Balanced load distribution
- Improved thermal stability
- Reduced wear at high speeds
- Acid/alkali resistance
- Suitable for H₂S environments

Advantages:


• Spring unit averted from the product so no sticking and clogging of the springs
• Safe operation (no fractures) because of seal face locking by square pin
• Suitable for pressure reversals
• Operation in vacuum without additional seat locking possible
• No damage of the shaft by a dynamically loaded O-Ring
• Small installation sizes
• Best suitable for conversions, no adaptations of the pump
• Insensitive to solid containing and abrasive media
• Advantages of a balanced seal even with plain shafts
• Insensitive to shaft movements because of the stationary design


Application:


• Water and waste water technology
• Chemical industry
• Refining technology
• Dirty, abrasive and solid containing media
• Fugitive hydrocarbons (no API seal!)
• Sticky and stringy media
• Chemical standard pumps
• Sewage pumps
