A molten sulfur lift for providing a constant molten sulfur head with a varying inlet head is described comprising a vertical outer housing having a molten sulfur inlet, a cylindrical, vertical inner housing having an open bottom and an open top spaced above the floor of the outer housing and forming a vertical annular passageway between the walls of the inner and outer housings. A molten sulfur discharge pipe is in fluid communication with the upper portion of the inner housing below the open top thereof passing outwardly and downwardly from the inner housing through the outer housing for removing molten sulfur from the lift. A rotatable screw is confined within the inner housing extending substantially from the open bottom of the inner housing to the molten sulfur discharge pipe for lifting the molten sulfur from the lower volume enclosed by the outer housing through the open top of the inner housing and into the annular passageway. Flapper valve means are positioned within the molten sulfur discharge pipe for closing the discharge pipe and interrupting the flow of molten sulfur therethrough, and conduit means are in fluid communication between the lower volume enclosed by the outer housing and the discharge pipe at a point downstream from the flapper valve means for conveying molten sulfur from the lower volume to the discharge pipe.
