A compact centrifugal pump for transmitting molten metals and other liquids with an operating temperature of up to 380°C

A centrifugal pump for transmitting molten metals and other liquids with a working temperature as high as 380°C is described. The pump ensures a head pressure of up to 9 atm and a flow rate of up to 1 m 3 /h. A rotary torque is transmitted from the electric motor to the turbine of the pump by means...

Summary:A centrifugal pump for transmitting molten metals and other liquids with a working temperature as high as 380°C is described. The pump ensures a head pressure of up to 9 atm and a flow rate of up to 1 m 3 /h. A rotary torque is transmitted from the electric motor to the turbine of the pump by means of the alternatingpole magnetic coupling. The compactness of the design is ensured by a vacuum gap between the “hot” inner and “cold” outer half-couplings. The pump is applied in high-power X-ray and extreme ultraviolet sources for forming liquid tin jets used as updated electrodes (in sources based on a discharge plasma) or a updated target (in sources based on a laser plasma), where it ensures velocities of tin jets of up to 15 m/s.
