ABSTRACT:
Apparatus for delivering molten metal such as lead to a receiver comprising a variable speed pump and a delivery pipe leading from the pump. The delivery pipe has an upwardly extending portion which leads to a discharge orifice from which molten metal may be discharged. A variable speed motor drives the pump. A controller causes the motor to drive the pump selectively at a first speed sufficient to raise molten metal and maintain it at a predetermined level in the upwardly extending portion of the delivery pump and at a second speed sufficient to force molten metal in the delivery pipe from the discharge orifice.
