A non-contact labyrinth seal is a type of mechanical seal designed by layering together metal sealing plates that combine to form a bunch of angles in a “maze-like” pattern. This complex maze-like pattern prevents contaminants and splashing liquids from hitting the bearing. Labyrinth seals are usually the first barrier of protection and
