Helical type EM induction pump with permanently magnetized rotor for high pressure heads

In the framework of the collaboration between the Institute of Physics of University of Latvia (IPUL) and the Institute for Plasma Research (IPR, India) a helical-type electromagnetic induction pump with rotating permanent magnets for high output discharge pressure heads up to 13.0 bars and flow rates of lead/lithium eutectic alloy up to 3.0 L/s with the operating temperature 350 °C has been developed. Results of the pump tests demonstrate a very good agreement between the theoretically calculated pump pressure-flow rate characteristics and the actually measured pump characteristics. This pump will be used at IPR for the liquid metal loop in liquid metal MHD experiments and in other R&D experiments, including studies of thermo-fluid MHD phenomena with the lead/lithium eutectic alloy as the process fluid in a strong transverse magnetic field. That is why the high pump output discharge pressure was specified as the main pump parameter.
