A centrifugal pump includes: a rotating blade member including an impeller member and a rotor magnet associated with the impeller member, a main body casing in which the rotating blade member is accommodated, a coil portion that rotates the rotating blade member, wherein the coil portion is located on a periphery of the rotor magnet, and an axial member which is associated with the main body casing, wherein the rotating blade member pivots around the axial member. A clearance, in which the rotor magnet is allowed to move, is provided between the blade member and the rotor magnet.

Centrifugal pump

A centrifugal pump includes a rotating blade member including an impeller member and a rotor magnet, a main body casing accommodating the rotating blade member, a coil portion that rotates the rotating blade member is located on a periphery of the rotor magnet, and an axial member associated with the main body casing. The rotating blade member pivots around the axial member. The axial member includes an end portion at axial rotor magnet side, and is fixed at the end portion. The main body casing forms a fluid introducing passage, and is associated with a blade casing accommodating the rotating blade member. An end portion of a bearing portion at an axial fluid introducing passage side is protruded such that the end portion of the bearing portion protrudes from an inner periphery opening portion of the blade casing into the fluid introducing passage.
