Sucker rodis an important part of a sucker rod pumping equipment.Sucker Rodconnect with coupling to be a rod string, and up through polished rod connection on the pumping unit or PCPmotor, down connection onthe pump piston or PCP, its role is to ground the reciprocating movement of the pumping unit horsehead suspension point is passed to the downhole pump or pass the rotation of the PCPmotor torque to downhole PCP.
