Cook Pump Company was born in 1958 right here in Coffeyville Kansas for the explicit purpose of designing and manufacturing world class Oil Well Pump Jacks. Because we are right in the middle of shallow well territory, and because of the low operating cost and long term dependability provided by Cook Pump Jacks, our models 2D through 7D very quickly became the preferred Pump Jacks of oil producers. As industry requirements changed, our Pump Jacks were redesigned and redeveloped into the updated "DB" Model Pump Jacks everyone knows today. Cook continues to take advantage of new materials and constantly changing technology to continually provide the Oil Patch with better quality Pump Jacks.
