Abstract

The present invention provides a pump rotatable at a high speed while minimizing wear between a bearing and a shaft. The pump comprises an impeller (1) having a large number of vanes (2) on the outer periphery of a cylindrical part (1A) and having a rotor magnet (3) on the inner periphery of the cylindrical part (1A), a motor stator (4) installed on the inner peripheral side of the rotor magnet (3) and rotatingly driving the impeller (1), a separator (6) partitioning airtight the impeller (1) from the motor stator (4), and a pump casing (5) having a suction port (9) and a discharge port (10) for sucking and discharging a liquid. Dynamic pressure generating grooves (12) generating dynamic pressure by the rotation of the impeller (1) are formed in the outer peripheral surface (8a) of the bearing of the impeller (1) and at least one of the cylindrical surface (6a) of the separator (6) and the cylindrical surface (5a) of the pump casing (5) facing the outer peripheral surface of the bearing.
