A review of existing designs of stages of submersible centrifugal pumps, research and ways to increase of head. The main causes of energy losses in the flow parts of pumps of the ESP type are described. A numerical model for simulating multiphase flows has been determined. Numerical simulation of the flow of GLM is carried out. The ways of increasing the assertiveness are determined. The values of the head in the moving and stationary elements of the flow part are obtained. headlosses in submersible centrifugal pumps are analyzed. A modified flow part is proposed, which allows to reduce hydraulic losses and increase the power of the entire stage as a whole. The calculation of the modified step is carried out. The flow of the gas-liquid mixture in the modified stage is visualized. The pressure and energy characteristics of the new stage are obtained. The distribution of static pressure along the blade is shown for different gas contents.
