ERT Power Sections

ERT power sections are engineered to provide the power for even the most challenging drilling applications.


Description

It all comes down to power.

ERT™ power sections deliver significantly more power compared to conventional designs. These stators are engineered as contoured steel tubes and injected with the most advanced NOV elastomer technology. The even wall technology enables you to push the limits of your operation further, providing superior power to the bit. Enhance the drilling performance of your next well with an ERT power section.

Steel Contour Backbone

ERT technology leverages a precision-engineered steel contour backbone that prevents lobe flexing and maintains a superior hydraulic seal. This robust design maximizes power section efficiency, ensuring optimal performance in demanding drilling conditions.


Efficient Heat Dissipation

NOV's ERT technology optimizes elastomer heat dissipation, reducing thermal build-up and minimizing heat degradation. The steel contour tube efficiently disperses friction-generated heat from the elastomer. This innovation extends drilling motor life and enhances overall motor reliability.


Elastomer Stability

Our ERT technology delivers consistent torque output by enhancing elastomer stability and improving the structural integrity of the hydraulic cavities. This design minimizes torsional vibration, enabling steady directional control while delivering more power to the bit.

High Performance NOV Elastomers

Our proprietary elastomers ensure the reliability and performance you need to meet the demands for each unique drilling application.

  • POB - Hard Rubber. Versatile. Reliable.
  • XTH - Superior performance for extreme environments.
  • XRT - Unparalleled power and durability for the harshest drilling applications.
