Series 88B2 is multiple springs externally mounted reverse balanced seal with O-ring as secondary sealing member.
Various seal face materials and elastomers can be offered for wide service application. This seal can also be used for
corrosive services as the metallic components do not come in contact with liquid to be sealed. This seal can also install in
double back to back arrangment as a internal seal. Even if barrier fluid pressure gose down this seal will not allow process
fluid to mix with barrier fluid, Hence it is called reverse balanced seal. |
