Pump jack is a reciprocating piston pump in an oil well. It is known by various names such as nodding donkey, horsehead pump, rocking horse, beam pump, and oil jack in the oil industry. Subsurface fluids (i.e. oil and water) cannot reach to the surface if there is insufficient bottom-hole pressure in an oil well. Pump jack is used for mechanically lifting the oil from an oil well in such a scenario. Pump jack converts the rotary motion of the motor into the vertical reciprocating motion, ... Read more
