Face to Face Dual Seal Designs
FACE TO FACE DUAL SEAL DESIGNS F006
In this design the seals are facing each other, with a low pressure buffer fluid circulating between them.
Unlike tandem seal designs, it has the advantage of being a dual seal with a single gland.
Some seal companies run the dual seals against a common stationary face. This is generally not a good idea because the stationary face can break and you will lose both seals.
