Power Sections and Flex-Coupling

TransmissionsOur field-proven power section designs provide the optimal combination of speed and torque delivered directly to the bit. Cobra has the right power section to meet the most demanding environments. Speed and torque delivered from the power section is transferred via a high strength flex-coupling transmission for maximum torque output and reliability. This is the highest rated transmission on the market. For more information on Cobra Downhole Motors’, please call us at 281 587-0005 or visit our web site at www.cobradownhole.com.

A three point geometrical model is used to determine a theoretical build rate potential of a given motor. Many factors (e.g. weight on bit, formation type, bit type, etc. affect the actual build rate achieved. Therefore these build rates should only be used as a guideline.
