PURPOSE:To reduce the facility cost by feeding part of a heat medium to a canned motor section from the heat medium outlet of a user having the heat medium outlet temperature lower than the pump intake side temperature. CONSTITUTION:The rear end side 17b of a canned motor 17 is connected via a pipe 41 to the heat medium outlet 4b of a user 4 among users 2-4 having the heat medium outlet temperature lower than the temperature of the intake side 38. The front end side 17a of the canned motor 17 is communicated to the intake side 38, and the bearing of the canned motor 17 is effectively lubricated and cooled. Accordingly, a heat exchanger, a cooling jacket, and a cooling water supply facility are not required, and the cooling water is not required to be fed.
