    • PROBLEM TO BE SOLVED: To provide a centrifugal liquid pump device that can rotate an impeller without making the impeller touch the inner surface of a housing using a pressure generated by a dynamic bearing and can maintain supplying a liquid when a trouble occurs in a control mechanism of a magnetic bearing.
      SOLUTION: This centrifugal liquid pump device 1 comprises a pump main body 5 provided with a pump section 2 having an impeller 21 rotating in a housing 20, a rotor 31 having a magnet 33, a motor 34 rotating the rotor, an electromagnet 41 for attracting the impeller, an impeller position detection sensor 42, and a dynamic bearing means 38 formed on the inner surface of the housing 20, and a control mechanism 6. The control mechanism 6 has a position sensor output monitoring function 56, an electromagnet electric current monitoring function 57, and a motor current monitoring function, and has an emergency impeller rotation function that judges a sensor malfunction or an electromagnet malfunction by using the position sensor output monitoring function and the electromagnet current monitoring function, functions at the time of detection of the malfunction, and rotates the impeller by using the dynamic bearing means.
