FIELD: oil industry.
SUBSTANCE: device has pressure drop valve adjusted for opening pressure, inserting bar pump with drive from swaying plant and mouth latch. Device has hydraulic jack mounted in tubing pipes hollow, body of which is connected by hollow polished rod to swaying plant, and piston - by bars to elongated plunger of pump. Pump cylinder is perforated above and below the lock support, forming together with plunger a pressure drop valve. Length of plunger is more than total length of drive of swaying plant and distance between perforation apertures.
EFFECT: higher efficiency.
