High Performance Emission Seals

The seal is mounted on the atmospheric side of the primary seal preventing the escape of the minute, normal emissions from the primary seal faces to the environment.

Leakage of media such as propane, propylene or other volatile hydrocarbons is normally gaseous and is vented to flare or other collection system. Liquid leakage may be collected below the seal gland plate and disposed of to a safe drain.

Salient Features:
* Stationary metal bellows allow very precise control of seal face loading, critical to dry contact sealing.
* Seal face materials developed specifically for dry contact application providing minimal friction and wear characteristics.
* May be nitrogen purged to prevent build up of hazardous gases in the seal quench space.
* May be used as a liquid seal for conventional tandem seal application.
