Abstract: A pumping system is described comprising a bracket being vertically fixed onto the connection end of a pump basement and also connected to a wellhead in order to support multiple fixed pulleys fixed on the same plane as the top end of the bracket), an electric motor and a speed reducer also successively being fixed to a lower end of the bracket. The end head of an output shaft of a speed reducer is connected by means of a crank whose top end head is connected with a movable pulley that is on the same plane as the fixed pulleys. A flexible cable vertically hung in the center of the wellhead is successively wound across the fixed pulleys and the movable pulley and then is locked onto the pump basement. The flexible cable is downwardly connected to a plunger element of an upper wellhead canned pump and also to a plunger element of a downhole oil well pump.
