Gas Barrier and Containment Seals - Gtsp
About this product
GTSP seals are dual pressurized, high temperature metal bellows gas seals for the hottest process pumps found in refinery and hydrocarbon services. Utilizing Flowserve’s exclusive bi-directional wavy face topography, GTSP seals pressurized with dry steam or nitrogen are specially engineered to drive exceptional, long-term equipment reliability and lower energy consumption.
Features and Benefits
- Dual pressurized gas seal design eliminates process leakage and coking problems in a compelling economic design that avoids liquid barrier-related seal issues.
- Laser-applied wavy face technology creates a gas film barrier between the seal faces to provide non-contacting, low drag, low energy consumption performance.
- Sinusoidal waves allow bi-directional operation to simplify installation on double-ended pumps and the smooth wave texture is self-cleaning to resist contamination or fouling.
- Alloy 718 welded metal bellows assembly construction offers the highest resistance to stress corrosion cracking in high temperature, sulfuric-laden services.
- Designed to operate without cooling and at full process temperature, the cartridge seal tolerates high axial overtravel during pump warm-up or thermal transients.
- Patented spring-energized graphite (SEG) seals absorb differential thermal expansion to maintain flat seal faces and low steam leakage rates.
- Qualification tested per API 682 Type C requirements for 3NC-FF designs, GTSP seals
are suited for hot hydrocarbons such as hot oils, gas oils, asphalt and heat transfer fluids.
