3 1/2" 6:7 3.7 Stage
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.
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.
