The Type 670 is an all Alloy C-276 rotating bellows seal, providing
high strength and excellent corrosion resistance. It is extremely
durable in applications where temperature and media (fluid) result
in an aggressive environment. The Type 670 has been tested per
API-682 Type B seals for low-temperature refinery services. Other
common applications include acids, caustics, amines, and products
with H2S, such as sour water and sour hydrocarbons. The Type 670
can be designed as a dual seal using a non-pressurized buffer or
pressurized barrier fluid. A pumping ring recirculates barrier
fluid, assuring cooler operating temperatures and extended reliable
performance.
