AESSEAL

Hydrostatic Hydrodynamic Compressor Seal

AESSEAL® has unique patented hydrostatic and hydrodynamic Dry Gas Compressor seal technology, offering robust protection for the sealing surfaces during start-up, shutdown, slow roll and upset conditions.

The HHCS™ is a tandem cartridge seal where the inboard seal is designed to seal up to 150 bar (2175 psi), and an outboard seal that acts as a low pressure tandem seal. The outboard seal is capable of full pressure containment in the event of full seal failure.

The tandem arrangement can be supplied with intermediary labyrinth for inert gas buffer duty. Single and dual seal options also available.

Features:

• Unique, patented hydrostatic and hydrodynamic Dry Gas Compressor seal technology offers robust protection for the sealing surfaces during start-up, coastdown, slow roll and upset conditions
• Increased hydrostatic lift for early face separation at much lower pressure differential than conventional seals
• Supplied in 410 stainless steel as standard with exotic alloy options on request
• Dynamic leakage considerably lower than comparable conventional spiral groove seals
• Available with Silicon Carbide seats as standard. Silicon Nitride seats available on request. Mating faces available in Carbon and synthetic diamond coated Silicon Carbide
• Capable of withstanding unintentional reverse rotation
• ‘O’ ring and spring energized polymer versions available
