The Nodding Donkey Pump
My mother grew up on an "oil lease" in Torrance, California. My grandparents moved to California from Nebraska sometime in the 1930s and rented a house within 50 yards of a pumpjack. They raised three children in that home. I remember going there many, many times as a child as we also lived in Torrance. Mom told me she and her siblings would crawl onto the pumpjack and ride it. This is in the day when girls always wore long dresses. It was dangerous, but they didn't know that or didn't care.
A pumpjack is the overground drive for a reciprocating piston pump in an oil well. A pumpjack is also called a beam pump, walking beam pump, horsehead pump, nodding donkey pump (donkey pumper), rocking horse pump, grasshopper pump, sucker rod pump, dinosaur pump, Big Texan pump, thirsty bird pump, hobby horse, or just pumping unit.
It is used to mechanically lift liquid out of the well if there isn’t enough bottom-hole pressure for the liquid to flow to the surface. The arrangement is often used for onshore wells. Pumpjacks are common in oil-rich areas.
Depending on the size of the pump, it generally produces 1.5 to 10.5 US gallons of liquid at each stroke. Often this is an emulsion of crude oil and water. Pump size is also determined by the depth and weight of the oil to remove, with deeper extraction requiring more power to move the increased weight of the discharge column (discharge head).
A beam-type pumpjack converts the rotary motion of the motor to the vertical reciprocating motion necessary to drive the polished-rod and accompanying sucker rod and column (fluid) load. The engineering term for this type of mechanism is a walking beam. It was often employed in stationary and marine steam engine designs in the 18th and 19th centuries.
