The application relates to the technical field of centrifugal pumps, in particular to an energy-saving high-temperature-resistant centrifugal pump capable of conveying crystallized materials, which comprises a motor, a support and a pump body, and further comprises an inner rotor assembly, an outer rotor assembly, a jacket assembly and a flow guiding part; the inner rotor assembly is connected with the pump body and is used for driving the pump body to convey liquid; the outer rotor assembly is connected with the motor and transmits mechanical energy of the motor to the inner rotor assembly through magnetic coupling. The flow guiding part driven by medium pressure is arranged, automatic switching of two working conditions is cleverly realized. When medium flows in the pump, the static pressure of the medium makes the flow resistance assembly open, the medium itself is allowed to flow through the bearing cavity for flushing and lubrication, meanwhile, the flushing liquid passage of the jacket assembly is closed, so that pollution of external flushing liquid to the conveying medium is avoided. When there is no medium in the pump, the medium channel is automatically closed and the flushing liquid passage of the jacket assembly is opened, external flushing liquid is used for flushing, cooling and anti-crystallization protection of the bearing.
