Applications

The GF is a mechanical seal recommended for applications where particular product purity must be ensured and where friction heat causes its changes. It is designed to work with toxic, carcinogenic, explosive media, for process gases, etc., in chemical, petrochemical, pharmaceutical, metallurgical industries and coking plants.
Features:
- very long lifetime and long MTBF (mean time between failures),
- possible operation in media, which do not form a lubricating film,
- no emission of harmful media into the atmosphere, ensures complete leak tightness of the pump (also in the event of a barrier gas pressure failure occurs, the seal continues to operate in the contact mode).
