Abstract This research shows the performance of the strength analysis and dynamic analysis of the shaft strength of a centrifugal pump in an integrated NASTRAN / PATRAN system. There is conducted the calculation of a mechanical scheme for determining the stress-strain state of the rotor shaft of a centrifugal pump and constructed a 3D-model of the rotor of a seven-step centrifugal pump. Furthermore, there are determined voltage levels for zero and maximum flow. On the basis of these dynamic calculations, a damping element has been proposed that ensures a smooth entrance of CP into an operating mode - a magnetic coupling.
