Beam pumping systems were one of the first type of artificial lift used in the oil field and are still the most widely used means of artificial lift. A beam pump system lifts fluid by reciprocating a rod string that activates a positive displacement pump. The positive displacement pump is seated in the tubing string and set below the operating fluid level in the well ([[:file:artificial-lift_fig4.png|Figure 4]]). A surface pumping unit provides the power to reciprocate the rod string.
