A centrifugal pump includes a C-shaped sealing assembly including an annular spring disposed between opposing legs of a base member. The spring biases the legs away from one another into sealing positions. In other embodiments, a vertical pump may be provided so as to include an oil recirculation system which enables an oil-based lubricant to be utilized instead of grease. In still other embodiments, the axial location of a pump shaft may be adjusted by rotating a bearing housing relative to the bearing frame where the two are threadedly connected to one another.
