Double Balanced Seal

DOUBLE BALANCED SEALĀ D020

Sometimes called a two way balanced seal, this is a single mechanical seal that is hydraulically balanced in both directions.

It is a very desirable feature, but seldom provided by seal manufacturers.

Double balance will prevent the inner seal from blowing open in a dual seal application, if the stuffing box pressure falls, or the barrier fluid pressure increases.

Please seeĀ two way balance.
