摘要:
Systems and methods for bearing housings are disclosed. A labyrinth seal bearing housing includes: a first seal element that is structured and arranged to be connected to a wall of a mixing vessel; a second seal element that is structured and arranged to be connected to a rotatable shaft; and a bearing support that is structured and arranged to be connected to the first seal element. The second seal element is configured to rotate relative to the first seal element and the bearing support. The first seal element and the second seal element are structured and arranged to create a tortuous flow path between an exterior and an interior of the mixing vessel.
