The study outlined in the paper is aimed at calculating the kinematic and dynamic parameters of the vertical lift of a liquid with a helix. The paper contains expressions directed towards the calculation of the force acting on the liquid with one turn of a helix, the drag coefficient has been determined. A theoretical relation has been obtained that gives an opportunity, according to the value of the critical rotational speed of a helix, at which the rise of the liquid begins, to determine the
