An improved bearing bracket is provided for a submersible close-coupled motor and pump wherein the bearing bracket supports an outer non-rotating ring of a ball bearing that rotatably supports the motor shaft at a location between the motor and pump. The bearing bracket sealingly supports two concentric non-rotating seal elements that engage a radially extending flange mounted on the end of the motor shaft to provide a seal between the pump and the motor housings. The space between the seal elements is connected to a reservoir for supplying a lubricating and cooling medium for the seal elements. |
