PDM D-76.NGT.4/5.20.M1 is a new universal hydraulic downhole motor used for:
- drilling of oil and gas wells with 83,0-98,4 mm bits,
- well workover operations with rock bits, PDC bits, including bicentric ones.
Bearing section has axial multi-row rolling bearing and radial hard alloy bearings. All the threads are screwed applying 3M glue, and each motor is complete with safety sub.
A large volume of work can be done with one motor (it is especially important for hard-to-reach regions) as the overhaul life reaches approximately 200 hrs
