The design criteria for involute pumping unit is presented in this paper to meet the practical need of power saving in oil field. Through comparing different driving schemes, a structure that combines wrapping connector driving with rigid driving is adopted to obtain a 5 to 8 meter long stroke, thus may increase the efficiency of pump and decrease driving motor power at the same time. A compound head sheave is designed based on the involute features, in which a big constant diameter sheave and a small reducer one are included to decrease crank torque and its amplitude. The wire rope used in the pumping unit is a wearing part, whose failure mechanism is studied and the corresponding measures are proposed to prolong its life span.
