Abstract
A pump jack includes a number of standard components that have been sized and configured according to unique relative dimensions to produce a pump jack that reduces structural stress, increases bearing life and permits a lower cost of manufacture. These geometric ratios can be used to express the relative size and spacing of the crankshaft, crank arms, center bearing, equalizer bearing, walking beam and pitman arms. Pump jacks incorporating one or more of these geometric ratios can be sized and scaled for a variety of pumping applications.
