FIELD: engines and pumps.
SUBSTANCE: invention relates to oil production and can be used in cluster well operation using rod pumps. The rod pump cluster drive comprises a motor, a reduction gear with a crank and counterweight, posts with guide pulleys, rope suspensions with fasteners and mouth sealers. The proposed drive is furnished with dynamic load killer representing a two-arm lever running free on the shaft fitted on the crank. Note the mouth sealers are set inside the hole and represent tight pairs "long cylinder - short con rod" with diameters not less than those of the working pump.
EFFECT: higher serviceability due to killing dynamic loads, smaller sizes metal content ensured by reduced overall dimensions of guide pulley posts and drive base.
