Results of design investigations of free flexural vibrations of multistage centrifugal ring section pumps rotors with inboard journal bearings on pumped medium and results of experimental investigations for determination of critical speeds of these pumps rotors are given. The investigation were carried out using various design models and design methods and various measuring systems. They showed that rotors of the pumps designs being investigated were flexible.
