Abstract: The invention relates to a device for supplying casting installations with molten metal. Said device comprises a crucible into the melt of which a dosing pump dips and supplies a discharge tube (12) communicating therewith with melt. The discharge tube (12) and the pump tube (11) are interlinked via a U-shaped connecting tube (15) to give a one-piece crucible insert. The discharge neck (13) of the discharge tube (12) is mounted so as to be swivelable about the axis (30) of the discharge tube. The inventive design allows for a simple maintenance and production of the dosing device. Moreover, the crucible position no longer has to be adapted to the position of the casting installation.

Abstract: A worm pump for delivering a metal melt comprises a mounting flange, and a tubular pump housing mounted on, and suspended from, the mounting flange, the pump housing defining a lower inlet for receiving the metal melt and an upper outlet for delivering the metal melt. A drive motor is mounted on the mounting flange, the drive motor having a pump shaft extending into the tubular pump housing and comprising a conveyor screw between the inlet and outlet. A guide supports the pump shaft at a lower end thereof, and a universal joint is provided at an upper end of the pump shaft above the upper outlet, the universal joint permitting the pump shaft to pivot and the guide being arranged to support the pump shaft during a pivoting motion.
