Features:
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.
