Gas-lubricated cartridge seals
Double seal in "face to face" installation, compact (cartridge) design, balanced, dependent on the direction of shaft rotation (GFR - right, GFL - left), multi-spring. Requires powering with barrier gas.
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.
- 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).
Seal configuration: GFStep 1 / 3
Seal configuration: GFStep 2 / 3
Other material versions are available on request. Please consult the Sales Department of ANGA.
