Don-Nan Pump & Supply Company was founded by Vernon Carruth in 1962. With 20 years of experience in the pump and supply business, Mr. Carruth began the challenging process of building a service company that he named Don-Nan after his two children Don and Nancy. During the early years, Mr. Carruth's son (Don Carruth) learned the technical aspects of the pump business as well as the work ethic that has helped the company reach its current level of success.

From the beginning, the philosophic foundation of our business has been a commitment to excellence in service, quality, integrity, and innovation. With locations in the Permian Basin, Texas Panhandle, and Southeastern New Mexico, this philosophy lead Don-Nan to become one of the largest and premier API 11 AX manufacturers and pump repair facilities in the United States.

From our meager beginning as a two-man pump repair facility in Midland, Texas, our commitment to provide quality and value to our customers has been the cornerstone of our growth. Our manufacturing division was established in 1981 to continually provide quality service while reducing customer operating costs. Building on the success of the pump repair shop, supply sales were added in the early 80's. By 1994, we acquired our API 11 AX license and became a full line manufacturer of subsurface pump products.
