FIELD: oil producing industry; pumps.
SUBSTANCE: proposed pumping unit with rotor rod has frame, electric motor, driving shaft of drive, driving bevel gear, driven gear and collet chuck. Rotor rod is made for rotation relative to its geometric axis and engagement with pump. Pump is made in form of cylindrical housing which accommodates eccentrically installed rotor with two plates for rotation and delivery of oil at high pressure by means of intake hole in lower cover and delivery holes in bottom of housing, diaphragm and upper cover of pump housing.
EFFECT: reduced cost of oil production from non-deep lying beds, reduced consumption of power, increased capacity and reduced cost of pumping unit drive.
