Quality Control

Dyna-Drill’s ultra-modern plant and computerized engineering capabilities merge seamlessly with sophisticated machining tools and quality-assurance technologies to produce the next generation of power sections and components.

Dyna-Drill’s coordinate measuring machine is capable of accurately measuring parts dimensions within .0001 of an inch. The coordinate measuring machine utilizes a custom data acquisition software to measure power section rotor and stator core profiles.

Commitment to quality

  • Full traceability
  • 100% rotor profile inspection
  • Stator electronic gauges
  • Tube ultrasound testing
  • 100% inspection of serialized parts


Dyna-Drill power section performance is evaluated on a 1500 hp dynamometer powered by two triplex mud pumps. The dynamometer is capable of testing power sections as large as 12 inches in diameter and 300 inches long. Every Dyna-Drill power section design has been proved on the dynamometer prior to production release. Dyna-Drill offers power sections dynamometer testing to its customers. Our dynamometer is the largest in the industry.
