Bellows mechanical seal / high-temperature / metallic - GTSP
The GTPS high temperature, dual pressurized metal bellows gas seals are used for the hottest processes the pumps have to carry out. They are mostly used in hydrocarbon and refinery services. This seal features the Flowserve’s unique bidirectional wavy-face topography. It provides lower energy consumption and a long, reliable service life thanks to the fact that it is pressurized with the dry steam or nitrogen.
The wavy-face technology uses a gas film barrier to separate the steel faces and provide contact-less, low drag and low energy consumption performance.
The welded metal bellows constructions made out of alloy 718 provide top-class resistance to stress corrosion cracks in sulfuric-laden high-temperature services.
