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 a drive mechanism 1 interacting with pipe installation 2, one end of which is in the form of an overhand, and the other has funnel shape checker filling 3 and delivery flap disposed in the checker filling 3. Pipe installation 2 is provided with retention pin rigidly connected to plug 10, which move pistonwise relative to vertical part of the pipe installation 2. Lower end 12 of the plug 10 is hooklike and cooperates with the pressure valve. Upper end is made with screw and placed in a thread bush fixed to the vertical part of the pipe installation 2 with the possibility of rotation from a reversible electric drive 15.
EFFECT: invention is aimed to providing a drain of the pumped medium.
