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
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.
Dual pressurized, high temperature metal bellows gas seals for the hottest process pumps found in refinery & hydrocarbon services.
For installing BXH, BXHH, BXRH, BRC, GTSP, GSDH Series
Wavy face technology provides virtually no wear and full pressure backup seal containment capability for light hydrocarbon, crude oil, and other services. Used with a pusher or bellows primary seal.
Non-contacting, bi-directional, backup containment seal with wavy face technology for light hydrocarbon, crude oil and other services
The GF-200 is a dual pressurized gas barrier seal utilizing APGS non-contacting seal face technology. The LoDrag O-ring design provides optimum face tracking with a wide variety of material options. Inert barrier gas eliminates process contamination, reduces power consumption and provides zero process emissions in hazardous services.500 psi / 34.5 bar
The GX-200 is a dual pressurized gas barrier seal utilizing APGS non-contacting seal face technology. Welded metal bellows eliminate dynamic O-ring hang-up in a compact cartridge that fits ANSI and DIN standard bore seal chamber pumps. Inert barrier gas eliminates process contamination, reduces power consumption and provides zero process emissions in hazardous services.
