PROBLEM TO BE SOLVED: To provide a magnet-combining centrifugal pump without drawing air into a blood room and without increasing the blood filling quantity and the radial propelling force of the vane wheels. SOLUTION: This centrifugal liquid pump 1 is equipped with a housing 20 with a liquid inlet port and a liquid outlet port 23, magnetic bodies 25 inside, and an impeller 21 to transport a liquid (blood) by the centrifugal force of rotation. A motor to rotate a rotor equipped with a magnet for attracting the magnet body 25 of the impeller 21 and a rotor is also mounted and the impeller 21 is rotated by a rotation torque generation mechanism to give the rotation torque to the impeller 21 in a non-contact condition. The impeller 21 is equipped with a plurality of liquid passages 26 extending from the center to the outer periphery direction and a plurality of vanes formed between the liquid passages, and the magnetic bodies 25 are equipped in the vanes 18. |
