1. A system for transferring molten metal out of a vessel, the system comprising:
- (a) a vessel, the vessel including a cavity and including a transfer chamber having an opening in communication with the cavity, the transfer chamber including an uptake section above the opening and the vessel further including a tap-out opening in communication with the vessel cavity, the tap-out opening being positioned lower than the rotor;
(b) an outlet in communication with the uptake section and above the opening; and
(c) a molten metal pump having a motor, a drive shaft connected to the pump and extending into the uptake section, the drive shaft connected to a rotor, wherein the rotor is configured to move molten metal upward into the uptake section, where it exits 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.
