  • Patent number: 8376432
    Abstract: An impeller jig for lifting and positioning an impeller having a shaft bore in a pump. The impeller jig includes a frame, a lifting aperture attached to the upper end of the frame and a lifting point attached to the opposed end of the frame adapted to engage the shaft bore of the impeller. A pair of opposed jacks are attached to the opposed end of the frame and adapted to engage at least two opposed outer surfaces of the impeller adjacent to the shaft bore of the impeller thereby forming a stability triangle with the lifting point. Also, the impeller jig may further include a positioning weight adjacent to the lifting aperture for transferring the center of gravity of the impeller jig upwardly and sufficiently close to the lifting vertical centerline to permit the impeller jig to be positioned for engaging the impeller by the operator prior to lifting.
