Abstract:
Apparatus for moving a stream of molten metal in a bath of molten metal comprising:a pumping member adapted to be disposed in a bath of heated molten metal and to move a stream of molten metal as the pumping member is driven in a path of pumping motion; a power device adapted to be supported above the bath of molten metal and to be actuated in a powered motion; means for connecting the power device to the pumping member to move the pumping member in said path of pumping motion; a pump housing having a pumping chamber and an inlet opening, the pumping member being disposed in the pump housing, the inlet opening being adapted for receiving molten metal into said pumping chamber; the pumping member having a strainer plate having apertures for receiving molten metal into the pumping chamber as the pumping member is being rotated about an axis of rotation; and a slinger rib mounted on the strainer plate adjacent the apertures and upstream thereof so as to strike debris carried into the stream toward the apertures, in a direction away from said inlet opening as the pumping member is being rotated.
