All Adtech Drilling Motors are specifically designed for the Horizontal Boring Industry.
The 3 1⁄2” 6-7 Lobe Motor is a rugged, small-medium drilling motor, that for the oil field, would be a 2 7⁄8” motor. Adtech designed this motor with a 3 1⁄2” bearing pack instead of the 2 7⁄8” model thereby making it extra tough and long lasting. Adtech designed the same OD on the stator tube. Normally, the stator tube would have wall thickness of 1⁄4”. However, because Adtech designed/produced their own stators, the walls are a beefy 1⁄2” thick. This means stouter threads and less breakage of the motor. The 6-7 lobe design is medium range speed and has plenty of torque for all applications for the machines that use this size of motor.
Each of Adtech's motors have a sealed bearing pack to keep oil on the bearing for a smoother run.
