This invention relates to improvements in a liquid transferring device, in particular for molten metals, of the type comprising an inverted U-shaped siphon connected with a crucible to form a hydraulic circuit having one or more liquid inlet openings and connectable to at least one source of vacuum and at least one source of pneumatic pressure in order to suck the liquid into the crucible and then push the same through the hydraulic circuit and prime the siphon. The improvement comprises a degassing chamber located at the siphon bight and maintained under a pre-established negative pressure during the transferring operation.
