All Adtech Drilling Motors are specifically designed for the Horizontal Boring Industry.
The 5” x 4 1⁄4” 5-6 Lobe Motor has the same power section (rotor and stator) design as the 3 3⁄4” 5-6. This motor was designed to run with the original Ditchwitch boring machines that had 4 3⁄4” OD pipe but small pumps (not enough to run a regular 5” drilling motor). To better line up with that machine, Adtech engineers took the 5” motor bearing pack and joined it with the 3 3⁄4” 5-6 rotor and stator. By injecting rubber into a 4 1⁄4” tube, they were able to cut larger threads to line up with the 5” bearing pack. 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. As with the 3 3⁄4” 5-6, this motor is used for medium formations and has medium torque.
Each of Adtech's motors have a sealed bearing pack to keep oil on the bearing for a smoother run.
