1. A system for use with a vessel including a cavity for containing molten metal, the system being in fluid communication with the vessel cavity and including:
- (a) three walls and a fourth, common wall shared with the vessel;
(b) an inlet in communication with the cavity to permit molten metal to enter the transfer chamber;
(c) an enclosed inner section and an open section, the enclosed inner section having a first opening in communication with the open section;
(d) a pump positioned in the transfer chamber, the pump having a motor, a drive shaft having a first end connected to the motor, and a second end, and a rotor connected to the second end, wherein the shaft is positioned at least partially in the enclosed inner section and the rotor is positioned at least partially in the enclosed inner section;
(e) an outlet above the first opening and below the motor, wherein molten metal can exit the transfer chamber through the outlet;
(f) wherein the rotor has a diameter, and the enclosed inner section has an interior diameter, and the interior diameter is between ⅛
″
to 1″
greater than the diameter of the rotor; and
wherein, as the pump operates the rotor is rotated and directs molten metal up into the enclosed inner section and out of the outlet.

Abstract
The invention relates to systems for transferring molten metal from one structure to another. Aspects of the invention include a transfer chamber constructed inside of or next to a vessel used to retain molten metal. The transfer chamber is in fluid communication with the vessel so molten metal from the vessel can enter the transfer chamber. A powered device, which may be inside of the transfer chamber, moves molten metal upward and out of the transfer chamber and preferably into a structure outside of the vessel, such as another vessel or a launder.
