Electrical centrifugal pumps (ECP) by their construction are multi-section and multistage machines, and that circumstance initiates their essential vibration activity. Thou vibration characteristics of the pumps are the most essential factors for define of these machines reliability and life. The main goal of this work is to consider the characteristic features of ECP section functioning as dynamical system, to create the calculation scheme and mathematical model of structure and to fulfill its numerical analysis. Obtained results can serve as the basis for formulation of propositions for hole system vibration activity decrease.
