• DuraTester™ Drilling Motor Test Stand


    The DuraTester™ is a drilling motor dynamometer test bench ready to ensure your motor is ready for operation and decreases possible NPT.  It is designed to be operated safely and efficiently by one person. The DuraTester offers easy clamping and support systems for either straight or bent motors. In addition, the DuraTester offers a fast and simple means to couple the motor to high pressure fluid supply and easy connection of the motor output shaft to the dynamometer. Floor to floor time is therefore very short, so the unit offers a rapid turnaround on any test.
