To provide a pump having a structure capable of reducing manufacturing man-hours and time while securing a sealing performance between a rotor and a stator.SOLUTION: A pump according to an embodiment of the present invention comprises: a rotor capable of rotating around a center axis; a stator located on an outside in a radial direction of the rotor, and surrounding the rotor; a pump part connecting to one side in an axial direction of the rotor; a supporting member comprising a base part covering the stator from the one side in the axial direction, and a non-magnetic rotor housing part located on the inside in the radial direction of the stator, and internally housing the rotor; and a fixing member located on the outside in the radial direction of the stator, and surrounding the stator. The rotor housing part comprises a lid part covering the rotor from the other side in the axial direction, and a cylindrical part located between the rotor and the stator in the radial direction, and opened on the one side in the axial direction. The stator is fixed to the fixing member. The fixing member is fixed to the supporting member.SELECTED DRAWING: Figure 1 【課題】ロータとステータとの間のシール性を確保しつつ、製造する工数および時間を低減できる構造を有するポンプを提供する。【解決手段】本発明のポンプの一つの態様は、中心軸を中心として回転可能なロータと、ロータの径方向外側に位置し、ロータを囲むステータと、ロータの軸方向一方側に繋がるポンプ部と、ステータを軸方向一方側から覆う基部、およびステータの径方向内側に位置しロータを内部に収容する非磁性体製のロータ収容部を有する支持部材と、ステータの径方向外側に位置し、ステータを囲む固定部材と、を備える。ロータ収容部は、ロータを軸方向他方側から覆う蓋部と、径方向においてロータとステータとの間に位置し、軸方向一方側に開口する筒状部と、を有する。ステータは、固定部材に固定されている。固定部材は、支持部材に固定されている。【選択図】図１
