Pumping machine (650, 750) comprising: —at least two tubular elements (651, 751) containing pressurized gas and extending vertically in parallel and interconnected between them by means of a connecting element (652, 752); and —an electromechanical lifting system (600, 700) comprising a first cylinder (601, 701), interconnected to the tubular elements (651, 751) and comprising a substance compressible by a piston (601b, 701b); and a screw (602, 702) with a vertical axis Y coinciding with the axis of the pumping machine (650, 750). The screw (602, 702) is inserted inside a second thrust cylinder (658, 758), connected in sliding manner inside the first cylinder (601, 701), and has a first end (602b, 702b) fixed to the connecting element (652, 752) and a second end (602a, 702a) configured for sliding inside the thrust cylinder (658, 758) and overlying a chamber (605, 705) comprising lubrication and cooling oil overlying the piston (601b, 701b).
