Abstract

A pump for pumping molten metal includes a pump shaft having an upper end and a lower end. A motor is connected to the upper end of the shaft. An impeller is fastened to the lower end of the shaft. Support structure supports the motor above the molten metal. A base is disposed below the support structure including an impeller chamber in which the impeller is rotated by activation of the motor. The base includes at least one inlet opening leading to the impeller chamber and at least one outlet passageway leading from the impeller chamber. At least one support post extends between the support structure and the base enabling the base to be submerged in the molten metal beneath the support structure. A device enables the post to resist deterioration while the post is disposed in the molten metal.
