The 3-1/2" Advanced PDM Downhole Mud Motor for Coal Mining Applications is a state-of-the-art positive displacement downhole power drilling tool. Utilizing drilling fluid as its driving force, it transforms liquid pressure energy into mechanical power. As the mud, driven by the mud pump, flows into the motor, it creates a pressure differential between the motor's inlet and outlet. This pressure drives the rotor to spin around the stator's axis, transmitting torque and speed through the universal shaft and transmission shaft to the drill bit. This process enables efficient drilling operations. Widely acclaimed, our downhole motors are indispensable in drilling and workover operations for both oilfields and coal mines, setting a benchmark for performance and reliability.
