With over 100 motor modifications available across various power ratings, we can select the optimal ESP Motor-Pump combination to ensure maximum system efficiency.
ESP motors are categorized into series (sizes) and temperature rating groups.
Advanced manufacturing technologies ensure high quality and reliability of these submersible electric motors.
The use of specialized electrical materials allows for operation in well fluid temperatures up to 120°C (248°F), with high-temperature versions rated for up to 150°C (302°F).
After assembly on specialized test benches where individual component quality is strictly monitored, every motor undergoes full-scale testing under simulated downhole conditions, including heating to operating temperatures. 100% of motors are tested and meticulously inspected post-trial. Insulation resistance is verified using the Polarization Index (PI) method.
Each motor is supplied as a complete unit with a protector (seal section).
Recent developments also include 180-series (frame) motors. These are designed to drive ESP systems for pumping well fluids in oil wells with temperatures up to 90°C (194°F) and for Water Injection (WI/PPD) applications, provided the well deviation at the setting depth does not exceed 40°.
Based on customer requirements, motors can be equipped with the following options:
- Shafts and couplings with involute splines for improved torque transmission.
- Centralizers that screw into the motor base to prevent contact between the motor housing and the well casing.
- Jacking tools (jacks) to ensure the smooth assembly of tandem (sectional) motors.
