    摘要: In accordance with at least one aspect of this disclosure, a pump includes a housing having one or more fluid inlets and one or more fluid outlets. The housing is configured to act as a pump housing for passing a fluid from the one or more fluid inlets to the one or more fluid outlets and configured to act as a stator for a motor. The pump also includes a cylinder encased within the housing and mounted on a shaft for rotation within the housing. The cylinder is configured to act as an impeller to drive fluid from the one or more fluid inlets through the housing to the one or more fluid outlets and configured to act as a rotor for the motor.

    摘要: A boost pump includes a boost cover and a main pump housing engaged opposite to the boost cover with an impeller rotatably engaged between the boost cover and main pump housing. The impeller includes an inducer section comprising a hub including a plurality of axial blades extended therefrom, each of the plurality of blades including a root, a tip, first and second surfaces, wherein the each of the first and second surfaces is defined in TABLE 1. The impeller includes an impeller section comprising a shroud extending from the hub including a plurality of radial blades extended therefrom. Each of the plurality of blades can include including a root, a tip, and opposed pressure and suction sides extending from the root to the tip, wherein the each of the pressure and suction sides is a surface defined in at least one of TABLES 2-4.

    摘要: A impeller for a centrifugal pump has an inducer section. The inducer section has first and second pluralities of blades, each having a plurality of polygonal cross-sections defined by a plurality of vertices. The pluralities of vertices are defined by tables of vertex locations. A method of making a centrifugal pump includes forming an impeller that has an inducer section, as described above, and an impeller section. The impeller is fluidly connected downstream of the inducer section and has third, fourth, and fifth pluralities of blades, each having a plurality of polygonal cross-sectional areas defined by a plurality of vertices. The pluralities of vertices are defined by tables of vertex locations.
