Abstract For the DEMO torus vacuum system, liquid ring pumps (LRPs) with mercury as working fluid have been proposed. These vacuum pumps shall be used for pumping the torus down to a pressure The paper describes the proof-of-principle experiments that have been performed in the THESEUS pump test facility at KIT and its results. Special focus of the paper is given to operational aspects as well as to mercury handling procedures. The impact of these findings on the design of future LRPs in a DEMO relevant design is shown up and modifications of the existing design are proposed.
