  • Impeller for centrifugal pump, particularly for a recessed-impeller pump, and pump with such an impeller
    Patent number: 11499565
    Abstract: An impeller for centrifugal pump comprising: a disc, a succession of vanes which extend from the disc around the rotation axis, a central body, adapted for connection to a rotating shaft, the vanes having a profile with a double curvature: a first curvature with respect to a sectional plane that is parallel to the disc, a second curvature with respect to a sectional plane that is perpendicular to the plane of the disc, each one of the vanes comprising an inside curve and an outside curve with different curvatures: the inside curve having an angle of curvature chosen between zero and one quarter of a round angle, and/or the outside curve has an angle of curvature chosen between zero and one quarter of a round angle.

  • IMPELLER FOR CENTRIFUGAL PUMP, PARTICULARLY FOR PUMP OF THE RECESSED IMPELLER TYPE, AND PUMP WITH SUCH AN IMPELLER
    Publication number: 20210003134
    Abstract: An impeller for centrifugal pump, comprising: a disc, a plurality of vanes which extend from the disc, a central body, adapted for connection to a rotating shaft. Each one of the vanes has a profile with a double curvature: a first curvature with respect to a sectional plane that is parallel to the disc, a second curvature with respect to a sectional plane that is perpendicular to the one of the disc, the first curvature and the second curvature having their concavity directed toward the inside of the impeller.
