The electromagnetic flat channel pump is developed for transfer of liquid NF-Metals with a maximum melting temperature of 800°C. This pump system can be extended modular for higher performance. The pump is not self extracting, this only works if at least 1/3 of the pump system is filled with the liquid medium. The flat channel pump was conceived for the employment at high temperatures to maximally 800°C temperature. The performance of the pump is temperature-dependent. In order to be able to ensure the performance of the pump, we recommend to keep the magnet frame temperature under 400°C. If necessary a forced air cooling must be used.
