A submersible electric motor has feature to enhance thermal conductivity from the motor interior to the exterior. The motor has a cylindrical housing and a stator rigidly mounted within housing. A rotatable rotor is located within the stator. A gap formed between the stator's outer diameter and the inner wall of the housing is filled with a high thermal conductivity material to improve heat transfer from the motor. The remaining portion of the housing may be filled with a dielectric lubricant that has lesser thermal conductivity than the high thermal conductivity material.

A centrifugal submersible pump has wear resistant features to resist erosion due to sand laden fluid from a well. The pump has diffusers and impellers located within a housing. Wear resistant inserts are secured to the diffusers and impellers. The inserts include inserts with cylindrical surfaces for radial support and sealing, and inserts with flat transverse surfaces for thrust. The inserts are preferably formed of tungsten carbide and are harder than the material of the impellers and the diffusers.
