An impeller for a pump is disclosed herein. The impeller can include a hub having a fixed end and a free end. The impeller can also have a plurality of blades supported by the hub. Each blade can have a fixed end coupled to the hub and a free end. The impeller can have a stored configuration and a deployed configuration, the blades in the deployed configuration extending away from the hub, and the blades in the stored configuration being compressed against the hub.

A dishwasher comprising a chassis, a tub supported by the chassis and at least partially defining a treating chamber, and a pump that circulates wash liquid in the treating chamber. The pump has an impeller that has a cover, a base with an axis of rotation, and at least one fin protruding from the base. The impeller also has a cap removably coupled to the impeller and at least one blade integrally formed with the cap.

A combined pump and motor has a stator mounted for non-rotation in a housing. The stator has windings that create an electromagnetic field in the stator cavity when powered. An upper diffuser and a lower diffuser are mounted for non-rotation in the stator cavity. Annular clearances exist between the upper diffuser and the inner diameter of the stator and between the lower diffuser and the inner diameter of the stator. An impeller between the lower diffuser and the upper diffuser has an array of magnets circumferentially mounted around the impeller that impart rotation to the impeller in response to the electromagnetic field in the stator cavity. The array of magnets has at least one end portion extending into one of the upper and lower diffuser annular clearances.

A combined well pump and motor includes a housing having an axis, an upstream end and a downstream end. Diffusers are mounted for non-rotation in the housing, each of the diffusers having diffuser passages. An impeller is mounted between each of the diffusers for rotation relative to the impellers. Each of the impellers has impeller vanes defining impeller passages. The impeller has an exterior outer wall extending circumferentially around the impeller vanes, closing outer sides of each of the impeller passages. An array of magnets is mounted to each of the impellers. The magnets are spaced circumferentially apart from each other around the axis at a different radial distance from the axis than the impeller vanes. A stator is mounted in the housing. The stator has windings for interacting with the magnets to impart rotation to the impellers.
