Abstract
A bubble pump having a steel tube pump body having an interior formed from a ceramic material that resists attack by molten metal. The pump further has a nitrogen supply line attached to a lower portion of the pump body. The pump body and nitrogen supply line are covered with a ceramic cloth material that resists attack by molten metal. The pump also includes a discharge head attached to the top of the pump body. The discharge head is formed of a cast ceramic material that resists attack by molten metal and includes a distribution chamber therein which has an ellipsoidal dome shape with a generally flat bottom and an ellipsoidal top. The discharge head also includes two discharge nozzles which have a square cross section. These features provide the inventive pump with extended service life and reduced discharge turbulence of the molten metal.
