5" x 4 1/4" 9:10 2.9 Stage
The 5” x 4 1⁄4” 9-10 Lobe Motor has the same power section (rotor and stator) design as the 3 3⁄4” 9-10. This motor has become a favorite for customers who want to run a larger drill bit (6 1⁄4” – 6 3⁄4”) but with smaller pumps that only output 120 – 160 GPM. Primarily, the main difference from the 5″ x 4 1⁄4” 5-6 is the Lobe configuration, which allows for higher torque on harder rock formations.

Stator and Rotor sizes are subject to change at the discretion of Adtech. Power section specifications may vary due to environmental conditions. Operation of power section above the maximum recommended differential pressure will result in a decrease of stator life and performance.
