An electric pump composed of an MgB2 motor is combined with a superconducting level sensor using a thin CuNi-sheathed MgB2 wire to demonstrate the transfer of liquid helium. An impeller is attached to the lower end of a rotating shaft of the MgB2 motor and covered with an outer casing to form a kind of centrifugal pump. After that, the MgB2 motor with the impeller is located vertically inside a cryostat with an infill of the liquid helium. Another glass Dewar vessel is also prepared to receive the liquid helium transferred from the cryostat containing the MgB2 motor. The MgB2 sensor is used not only to detect the level of the liquid helium but also to control the electric pump on the basis of its pre-estimated calibration curve. By using the assembled pump system, the liquid helium is successfully transferred from the cryostat to the glass Dewar vessel via a transfer tube. The transfers of liquid hydrogen with the identical pump system will be carried out in the near future.
