MKDQZ-300B Pneumatic Water Well Drilling Rig
Overview
The MKDQZ-300B is an ultra-compact, lightweight crawler-mounted pneumatic DTH(Down-the-Hole) water well drilling rig tailored for 300m-class medium-shallow borehole projects. Powered by an 85kW Yuchai diesel engine and adopting mature down-the-hole air percussion drilling technology, it delivers consistent and efficient rock-breaking performance across soft soil, sand-gravel layers, granite, limestone and other hard rock formations. With a drilling depth of up to 300m and a bore diameter range of 140–325mm, this rig is ideal for rural domestic water supply, agricultural irrigation wells, foundation dewatering, residential boreholes and small-scale geothermal drilling.

Key Features
1. 300m Rated Drilling Depth with 140–325mm Wide Bore Range
This pneumatic borehole rig supports a maximum drilling depth of 300 meters and adapts to bore diameters from 140mm to 325mm, fully covering the construction needs of most residential water wells, farm irrigation wells and small industrial water projects. One single unit handles both small-diameter deep water wells and large-diameter shallow dewatering holes, eliminating the need for multiple equipment investments for different project types.2. 85kW Yuchai Diesel Engine with Fuel Efficiency & Global Parts Access
Equipped with an original 85kW Yuchai diesel engine — a globally recognized power brand with extensive after-sales networks and readily available spare parts worldwide — this rig features sufficient power reserve, low fuel consumption and high durability. It maintains stable output even in high-altitude, high-temperature and dusty field environments, effectively reducing unplanned downtime and long-term operation costs.3. Triple Drill Pipe Diameter Compatibility for Flexible Configuration
The rig is compatible with drill pipes of Φ76mm, Φ89mm and Φ102mm diameters, and supports length options of 1.5m, 2.0m, 3.0m and 6.0m. Users can flexibly match drill pipe solutions according to well depth, bore size and geological conditions, avoiding extra procurement costs for additional drilling tools and improving equipment adaptability to different projects.4. 5700–7500N.m Low-Speed High Torque for Hard Rock Drilling
The power head delivers a wide adjustable torque range of 5700–7500N.m matched with a rotation speed of 40–70rpm. The low-speed high-torque output is specially optimized for hard rock formations, ensuring steady rock breaking, reducing drill tool wear and improving construction quality and borehole verticality in complex bedrock conditions.
5. 22m/min Rapid Lifting + 40m/min Fast Feeding for Higher Efficiency
Configured with a 22m/min rapid lifting speed and a 40m/min fast feeding speed, this rig greatly compresses the auxiliary operation time for drill pipe tripping. Compared with rigs of the same depth class, it significantly improves overall working efficiency, shortens single-well construction time and helps customers improve project profitability.6. 15–35m/h High Penetration Rate with DTH Percussion Technology
Adopting proven DTH(Down-the-Hole) air percussion drilling principle, the rig achieves a penetration efficiency of 15–35m/h in typical hard rock strata. Compared with traditional mud rotary drilling rigs, it greatly improves rock-breaking speed in dense geological conditions, shortens single-well construction cycles significantly, and enables drilling teams to take on more projects within the same operating period.Get a quote
