DR-240.NGT.3/4.63.М1

Description

PDM DR-240.NGT.3/4.63.М1 is a new universal hydraulic downhole motors used for drilling of oil and gas wells with rock and PDC bits of 295.3 – 374.6 mm diameter.

An adjustable bent sub is placed between bearing section and power section. The adjustment range is between 0° and 2° or between 0° and 3°.

The bearing section has multi-row thrust ball bearing of enhanced load-carrying capacity and radial hard alloy bearings.

PDMs are completed with imported extended power sections with enhanced operation life. The overhaul life reaches approximately 200 hrs.

PDMs can be completed with replaceable centralizer:
