A new, highly reliable gas-lubricated API 682 (ISO 21049) qualified high-temperature, non-contacting mechanical seal that utilizes internally pressurized outward pumping spiral groove face technology with high-temperature seal features such as Inconel-welded metal bellows and non-elastomeric flexible carbon graphite secondary seals. This innovative design technology is ideally suited for reliably sealing high-temperature process fluids on rotating equipment up to 800°F/425°C and fluids requiring inert secondary seals. Innovative alternative to conventional wet contacting seals that permits reliable operation in high-temperature services. Fugitive emissions for Maximum Achievable Control Technology (MACT) compliance for sealing higher-temperature, volatile or hazardous fluids. API 682/ISO 21049 qualified. Elastomer-free seal handles a wide range of applications. Eliminates problems associated with coking barrier fluids and fouled heat exchangers. Features California Residents: PROPOSITION 65 WARNING API 682/ISO 21049 qualified. Centrifugal advantage: process fluid at the OD of the bellows. Pressure-balanced design withstands full reverse pressurization. Static secondary seals have high-temperature capability and eliminate the cost of expensive perfluoro elastomers. Edge-welded metal bellows. Dual mating ring arrangement meets API 682 design requirements. Spiral groove technology for superior operating performance. Eliminates problems with coking barrier fluids and fouled heat exchangers.
