ERT Downhole Motor

ERT Downhole Motor Advantages

Lifespan: Increased 40% compared with the conventional PDM of the same size.

Stator: High precision ERT design is applied.

Rubber: Hardness of HA82, power attenuation reduced, output performance better.

Rotor: Special manufacturing processes are used to create a thicker chrome plating layer and eliminate pinhole phenomena.

Linear Optimization: The motor efficiency is improved by 15% after optimization.

Assembly: With smaller interference fit, the internal frictional resistance is lower, the starting pressure can be reduced by 1-2Mpa.

Torque: Increased 25% compared with the conventional PDM of the same type.
