Rotating Drum - Face Sealing Mechanism
Rotating Drum - Face Sealing Mechanism
(OP)
Hello all.
Does anyone know what the sealing mechanism involves in sealing the two opposing flow areas from one another in continually rotating devices - similar to these:

I have a similar sort of problem where I need to seal against the rotating face. I was considering using an inflatable elastomeric seal with some sort of PTFE coating or PTFE lip seal - anybody had any experience of such things?
Thanks in advance.

Since you already have the air flows available, have you considered an air purge labyrinth? Use differential area and pressure (shear) to keep the wet air from the dry, eliminating the need for a mechanical seal system.
