FIELD: oil producing industry. SUBSTANCE: invention relates to submersible centrifugal pumps and to pipe valves and fittings. Proposed vibration damper contains solid bushing with cover at one end face and shoulders at the other. Grooves and projections are made on flanges, cover and shoulders of bushing. Flexible collars are fitted in grooves. Vibration damper should be preferably installed between electric centrifugal pump and oil well tubing. Vibration damper of proposed design reduces vibration of centrifugal pumps, jerks at starting and rotating torques providing possibility of operation of pumps in slanted wells and playing the part of articulated and sealing joint. EFFECT: improved reliability in operation. 1 dwg
