Lubrication of a centrifugal pump bearing

Image Number 4 for United States Patent #5051007.

Lubrication system for a centrifugal pump having a bearing mounted around a rotatable vertical shaft. The lubrication system includes a reservoir for holding a quantity of lubricant, structure for withdrawing lubricant from the reservoir, a stator, and a passageway for communicating lubricant from the reservoir to the bearing. The withdrawing structure includes a rotor connected to the vertical shaft. The stator encircles the rotor with the rotor and stator extending axially into the reservoir. The stator minimizes vortexing and churning of the lubricant in the reservoir during rotation of the rotor. Dynamic seals are not necessary with the lubrication system. Accordingly, concern of heat generation and wear associated with dynamic seals has been eliminated.
