Lufkin Industries > Downhole Pumps > Engineering Services

Don-Nan has an in-house team of engineers to assist our rod lift experts. The Engineering & Tech Team work together to develop the best solutions in an efficient, reliable manner for our customers.


We offer custom designs tailored to individual job specific sites with over 100 years of oilfield knowledge. The response time of our team is unmatched and our engineering background assists in designing the pump custom to the wellsite. The Technical Team provides pump schools for our customers to extend and promote education of the application of SRP and downhole components.

Design Control

All components that are manufactured are designed by our in-house engineering team.
From drafting to nodal analysis, all components have been reviewed for the best design to
be provided in the field. Standard pump components have been 11AX reviewed,
certified, and design controlled by the Engineering Team.

Laboratory Services

When pumping, certain factors are associated with failures. The Engineering & Tech Teams are specialized in determining the root cause of the failure and providing information back to the necessary parties for optimizing pumping performance and preventing from future failures. Many services performed in our Materials Characterization Lab, we offer as complimentary services and reports for customers looking to optimize performance, minimize risk, and lower lift costs.
