MKDQZ-450 Pneumatic Water Well Drilling Rig
Overview
The MKDQZ-450 is a cost-effective crawler-mounted pneumatic water well drilling rig engineered for medium-depth borehole construction. Driven by a 110kW Yuchai diesel engine and adopting DTH(Down-the-Hole) air percussion drilling technology, it delivers stable and efficient rock-breaking performance across soft soil, sand-gravel layers and hard bedrock like granite and limestone. With a maximum drilling depth of 450m and a bore diameter range of 140–350mm, this rig is widely applicable to rural domestic water supply, agricultural irrigation wells, foundation dewatering and small geothermal drilling projects.

Key Features
1. 450m Max Drilling Depth with 140–350mm Wide Bore Compatibility
This rig supports a maximum drilling depth of 450 meters and adapts to borehole diameters from 140mm to 350mm, fully covering the construction demands of most residential water wells, farm irrigation wells and small industrial water projects. One unit handles both small-diameter deep wells and large-diameter shallow wells, eliminating the need to invest in multiple equipment for different project scales.2. 110kW Yuchai Diesel Engine with Global Service Support
Equipped with an original 110kW Yuchai diesel engine — a widely recognized power brand with global after-sales networks — this rig features sufficient power reserve, low fuel consumption and high durability. It maintains stable output even in high-altitude, high-temperature and dusty working environments, with easily accessible spare parts worldwide, minimizing unplanned downtime and long-term maintenance costs.3. 7000–9500N.m Adjustable Torque with 30–135rpm Wide Speed Range
The power head provides a wide adjustable torque range of 7000–9500N.m matched with a rotation speed of 30–135rpm. It can be flexibly switched according to formation conditions: low-speed high-torque mode for hard rock to ensure steady rock breaking, and high-speed low-torque mode for soft soil and sand layers to improve drilling efficiency, achieving optimal construction results across diverse strata.4. Multi-Spec Drill Pipe Options for Flexible Project Matching
The rig is compatible with Φ89mm and Φ102mm diameter drill pipes, and supports length options of 1.5m, 2.0m, 3.0m and 6.0m. Users can flexibly match drill pipe configurations according to well depth, bore size and geological conditions, avoiding extra procurement costs for additional drilling tools and improving equipment adaptability to different projects.
5. Compact Lightweight Design for Low-Cost Logistics & Narrow Site Adaptation
With a total weight of 9.2 tons, overall dimensions of 6150*2200*2600mm and a loading width of only 2.8m, the rig can be transported via standard flatbed trucks and standard shipping containers, effectively reducing long-distance logistics costs. Its compact body also adapts to drilling operations in narrow sites such as residential yards and rural village roads, expanding applicable construction scenarios.6. 15–35m/h High Penetration Rate for Hard Rock Formations
Leveraging mature DTH(Down-the-Hole) pneumatic 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 significantly boosts rock-breaking speed in dense geological conditions, cuts single-well construction duration by a large margin, and allows drilling teams to take on more projects within the same operating cycle.Get a quote
