A system for removing molten metal from a vessel is disclosed. The system includes a vessel having a first section and a second section and a pump positioned in the first section of the vessel. As the pump operates it moves molten metal through a pump discharge and through an opening into the second section of the vessel, where the molten metal reaches a vessel outlet and exits the vessel. The pump discharge is preferably formed at an angle to the vessel outlet. The outlet may be attached to a launder.

A method of casting is provided, wherein a molten material is introduced into a mould such that the molten material flows out of the mould, wherein once a desired temperature of the mould is achieved, the molten material is prevented from flowing out of the mould such that the molten material at least partially fills the mould.

Aspects of the invention relate to a rotor for transferring molten metal. A powered device, such as a molten metal pump, which may be inside of a transfer chamber, includes a multi-stage rotor to move molten metal within a vessel. The molten metal may be moved out of the vessel and into another structure, which could be another vessel or a launder. The multi-stage rotor may have multiple blades with each blade having multiple surfaces.
