Abstract of the Disclosure Apparatus for melting and pumping molten liquid material from a drum of material which is solid at room temperature and which comprises a platen assembly having a top platen and a lower heating platen suspended from the top platen but movable vertically relative thereto. A flexible, expansible sealing element extends between the peripheral edges of the top platen and the lower heating platen so that when the platen assembly is lowered into the open top of a drum of solid material and contacts the top of the solid material, subsequent downward movement of the top platen is operable to move the top platen downwardly toward the heating platen and cause the expansible sealing element to expand radially outward into contact with the interior surface of the drum. When the platen assembly is lifted from the drum, the top platen moves away from the lower heating platen and thereby contracts the diameter of the expansible element so as to move it out of contact with the interior surface of the drum.
