To improve the efficiency of the main petroleum pipeline operation and planning of operating modes when using the method of changing the rotor speed, it is necessary to carefully evaluate and predict the efficiency of pumps depending on the rotor speed. Therefore, experimental research of the dependence of efficiency on the rotor speed is needed. Various modes were considered: from the current frequency of 50 Hz to 25 Hz. The results of the study show us that with a decrease of the rotor speed, there is also a decrease in efficiency, which is opposed to the theory of similarity. The obtained results indicate that during the operation and planning of work, it is necessary to take into account the efficiency of the pumps for the correct forecasting of energy costs.
