Description:
Mechanical Face Seals are a special form of mechanical seals.They are also known under other designations, such as lifetime seals,floating seals,duo cone seals,toric seals and heavy duty seals.
Diameter 35mm Diameter 1425mm
Types:
There are two different types of Mechanical Face Seals:the most common form is Type DO,which is characterized by the use of an O-Ring as the secondary sealing element.
Type DF,on the other hand, has an elastomer with a diamond-shaped cross section as a secondary sealing element instead of the O-Ring.
Technical data for metal seal rings:
