Patent abstract
A pump for transferring molten metal includes an intake tube, a motor, a rotor positioned at least partially within the bottom end of the intake tube, a rotor shaft positioned at least partially in the intake tube, the rotor shaft having a first end attached to the motor and a second end attached to the rotor. An overflow conduit is attached to the intake tube. The pump does not include a pump housing and preferably does not include a superstructure, so it is relatively small, light and portable. In use, the motor drives the rotor shaft and rotor to generate a flow of molten metal upward into the intake tube and into the overflow conduit where it is discharged.
