* The product description:
The type 670 is a full Harcourt C rotary bellows seal. It is extremely durable and reliable
in a wide range of temperature and media applications. The type 670 seal has passed the
standard inspection of API682B seal and is suitable for low temperature conditions in
the oil refining industry. Other common uses include acids, amines, water containing sulfur,
and hydrocarbons containing hydrogen sulfide.
The type 670 can be designed with double face seal with no pressure buffer or pressure
isolator to maintain circulation of isolator through pump ring to ensure relatively low
operating temperature and durable and reliable performance. To meet more stringent
environmental and safety control requirements, the seal is available with dry operation
YTS-
The type 675 and 676 seals have the same superior performance as the type 670 seals,
only with different combinations of materials. Titanium bellows type 675 are ideal for
sealing with chlorine, ferric chloride, caustic soda and other media. type 676 of AM350
stainless steel bellows is suitable for slightly corrosive and abrasive media, such as various
water and papermaking materials.
