Centrifugal Seals vs. Labyrinth & Mechanical Shaft Seals

Rather than locking in fluid using internal pressure, like a centrifugal seal, a labyrinth seal by design will have some amount of leakage. Labyrinth seals must be produced with a "route" for the leaking lubricant to follow. This typically results in a complex, indirect path in the seal's internal labyrinth path through which the lubricant flows.
