In the mid-1950"s, the Mark II, a new, rotary counterbalanced, sucker rod type pumping unit was developed, employing a special Class III geometry and phased counterweights. This paper reviews some of the basic functional goals envisioned for this unit by its designers, and the degree to which they have been realized. Also discussed are several functional categories involved in sucker rod pumping and the influence the unit's unique geometry has upon each of them.
