  • Bearing assembly for a vertical turbine pump
    Patent number: 8790072
    Abstract: A bearing assembly for supporting a drive shaft of a pump is structured with a cylindrical body having an internal cavity filled with a lubricant, a sealing element arrangement positioned at one or both ends of the cylindrical body and a pressure equalization element that functions to equalize the pressure differential that exists between an area within the cylindrical body and outside of the cylindrical body to improve the operating life of the sealing arrangement and the bearing assembly.

  • Shaft coupler
    Patent number: 6877927
    Abstract: A shaft coupler to connect two coaxial segments of a drive shaft. Each segment includes a tongue, which tongues complement each other to transmit torque and resist axial separation. A bearing surface on each tongue lies within the locking angle of their material so as to resist lateral separation of the segments.
