China 300m Rotary Water Well Drilling Rig

300m Rotary Water Well Drilling Rig

The JK-DR300 pneumatic DTH drilling rig is capable of drilling up to 325mm diameter holes for pore-forming purposes to a depth of 300 meters.
JK-DR300 new generation multi-purpose DTH deep water well drilling rig is our independent research and development products. These new generation DTH are coupled to higher air power, and thus play a significant role in leading to faster drilling rates.
Adopting newest model & advanced hydro technology, our water well drilling machine are mainly used for well drilling in resource exploration and hydrology wells, civil use water well, agriculture irrigation project, and can also be used for coal-mine gas exploitation, coalbed methane, shallow layer of shale gas, terrestrial heat, or salvage work.
Made from high quality materials, with fashion and compact design, that keeps our drilling rigs more efficiency and with low failure rate, more economic and durable, and with a high comprehensive cost performance. Our water drilling rigs have received the real market validation as the majority of our customers' positive feedback.
