Abstract: An impeller designed for use in radial pumps. The impeller compensates for axial forces during pumping operations. The impeller utilizes vanes having 3D geometry which extend from the impeller intermediate plate eye to the external diameter of the intermediate plate. On the backside of the intermediate plate, the vanes define a plurality of hydraulic passages. The hub plate also includes a series of balancing holes.

Abstract: A fluid pump including an integrated pumping section and motor section may be achieved by a variety of techniques. In certain aspects, a fluid pump may include an integrated pumping section, motor section, and a control section that share structural components in order to reduce the structural material required for the complete device while simultaneously utilizing the integrated motor controller to enable the pump to operate at varying speeds other than the synchronous electrical power frequency that powers the device.
