FIELD: engines and pumps.
SUBSTANCE: invention relates to the field of pump construction, in particular to pumps for transferring viscous and corrosive liquids, molten metals, preferably media with a high level of radioactivity. Pump comprises drive mechanism 1 interacting with conduit 2, one end of which is designed as a cantilever, and on the other, funnel-shaped nozzle 3 is formed extending to the open end side, and a discharge valve disposed in nozzle 3 of conduit 2. In the lower part of pipeline 2, branch 13 is connected, communicating with the internal cavity of pipeline 2. At branch 13, valve 12 is mechanically connected to reversible electric drive 14.
EFFECT: invention is aimed to providing a drain of the pumped medium.
