Description
Non-contacting, Non-elastomer Metal Bellows Outward Pumping Dual Gas Seal for High-temperature Applications
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.
