PROBLEM TO BE SOLVED: To provide a compact, centrifugal type pump apparatus activating an impeller to smoothly rotate.
SOLUTION: The centrifugal type blood pump apparatus is equipped with the impeller 10 provided in a blood chamber 7, a permanent magnet 15 provided on one surface of the impeller 10, a permanent magnet 16 provided on the inner wall of the blood chamber 7, a permanent magnet 17 provided on the other surface of the impeller 10, and magnetic bodies 18 and coils 20 which are provided in a motor chamber 8 and drive to rotate the impeller 10 through a partition wall 6. The mutually facing surfaces of two adjacent magnetic bodies 18 are provided in parallel. Dynamic pressure grooves 21, 22 are respectively formed on the partition wall 6 facing the impeller 10 and the inner wall of a blood chamber 7. Consequently, the impeller 10 is smoothly activated to rotate by controlling a coil current.
