Abstract
A transfer pump system has a pump base with a pump chamber, tangential discharge and an outlet. A riser tube extends from the outlet and terminates at a launder in order to move molten metal out of a vessel with relatively little turbulence. A riser tube for use in the system has a proximal end configured to be connected to the outlet and a distal end that terminates at or above the launder.
Claims17
A pump configured to be positioned in a vessel that contains molten metal, the pump comprising:
- (a) a pump base having a pump chamber, a top surface, and an output port;
- (b) a riser tube having a passage therethrough, a proximal end having an opening in communication with the passage, the proximal end attached to the output port, a distal end opposite the proximal end, wherein the distal end has an opening in communication with the passage, the distal end being open;
- (c) a superstructure above the output port, the riser tube being supported by the superstructure;
- (d) a launder extending from the vessel to a second vessel, the launder having a first end, an open top, and a bottom having a launder opening juxtaposed the first end;
- and
- (e) the distal end of the riser tube being positioned in the launder opening, and terminating at or above the bottom surface of the launder, the distal end having a raised riser tube back portion and a lower front portion, the front portion having a height between:
- being 3″ above a top surface of the launder to being even with the open top of the launder.
