PROBLEM TO BE SOLVED: To provide a turbo pump constituted to prevent the action of radial partial load acting upon an impeller by the rotation of the impeller in a scroll chamber. SOLUTION: A turbo pump is provided with a rotor 1 for feeding a fluid; a rotatory-driving means provided outside a housing; a coupling means for magnetically coupling the rotor 1 to the rotatory-driving means through the housing; and a control type magnetic bearing. The rotor 1 is supported not in contact with the housing. A plurality of scroll chambers 21, 22 are provided, and the respective scroll chambers 21, 22 are symmetrically arranged with a rotating shaft of the rotor 1 as the center.
