Abstract
A slim pump according to the present invention includes a frame, a shaft-coupling portion, a stator, and an impeller. The frame includes an interior separated by a partitioning board into a first chamber and a second chamber. A flow inlet intercommunicates with the first chamber and a flow outlet intercommunicates with the second chamber. The first chamber is intercommunicated with the second chamber via a communication hole of the partitioning board. The shaft-coupling portion is located in the frame. The stator is disposed around the shaft-coupling portion and is located within an axial extent of the first chamber. The stator is axially aligned with the communication hole. The impeller includes a plurality of blades and an inlet opening located in the second chamber. The inlet opening faces and axially aligns with the communication hole.
