A liquid transferring device, particularly for transferring molten aluminum from a first container at a higher elevation to a second container at a lower elevation, includes a siphon-shaped pipe having a U-shaped portion disposed within the liquid in the first container. The end of the U-shaped portion above the liquid level in the first container communicates with an elevated crucible element, and the bight of the U-shaped portion is formed with a bore communicating with the liquid in the first container for partially filling the device with the liquid to be transferred. The crucible element has a sealed upper end connected to a conduit and the conduit may be selectively connected to a source of gas under pressure or to a vacuum pump. Initially, the conduit is connected to the vacuum pump to draw the liquid into the crucible and siphon in order to prime the siphon and start a liquid transferring operation, which may be assisted by disconnecting the crucible from the vacuum pump and connecting it to the source of fluid under pressure to apply a pressure pulse to the liquid in the siphon-shaped pipe. Following priming of the siphon-shaped pipe, the liquid transfer operation continues automatically with the liquid in the first container flowing through the bore into the siphon-shaped pipe for discharge into the second container.
