Info

As the motor turns the crank (in orange), the walking beam (in yellow) oscillates. The pumping (sucker) rod, which is immersed in the oil,  is connected to the horse-head of the walking beam by a cable. Therefore,  the oscillation of the walking beam is converted to the reciprocating motion of the pumping rod to pump oil.
