Lift-off & Dry Running

0

Gas seal technology and gas seal operation depends on aerostatic and aerodynamic forces. Careful design keeps the two faces separated by a gas film. Aerodynamic forces are created by the presence of a ‘pattern’ on one of the faces

Description Dual pressurized, high temperature metal bellows gas seal

 

  • Industries:
    Alkylation, Catalytic Cracking, Crude Handling and Treatment, Distillation, Heavy Oil and Upgrading, Hydrocraking, Hydrotreating, SAGD

The GTSP is a dual pressurized, high temperature metal bellows gas seal for the hottest process pumps found in refinery and hydrocarbon services.

Utilizing Flowserve’s exclusive bi-directional wavy face topography, the GTSP seal, pressurized with dry steam or nitrogen, is specially engineered to drive exceptional, long-term equipment reliability and lower energy consumption.

Wavy face technology creates a gas film barrier between the seal faces to provide non-contacting, low drag, low energy consumption performance.

Alloy 718 welded metal bellows assembly construction offers the highest resistance to stress corrosion cracking in high temperature, sulfuric-laden services.
