Product Description

Detailed Photos

^{Our company not only excels in producing and selling new machines but also boasts an extensive network of high-quality, cost-effective second-hand drilling rigs and air compressors. The advantages of our second-hand machinery are manifold, including affordability, excellent quality, and exceptional cost-effectiveness.}

1. This Water Well Drilling Machine is a highly efficient and multifunctional piece of groundwater drilling equipment. It is perfect for drilling water wells, agricultural irrigation wells, geothermal wells, and other types of wells. Its design makes it especially suitable for water intake projects in mountainous and rocky terrains.

2. The drill pipe holder features automatic pressure maintenance and clamping functions and works seamlessly with the chuck-type power head for synchronized control. This ensures quick response times and reliable, safe operation. The proprietary mud treatment system, equipped with a customized high-pressure mud pump, is lightweight, minimizes pulse, and handles both high-solid phase and circulating mud effectively.

This machine is powered by a high-torque hydraulic motor and a branded diesel engine. The hydraulic control system uses a large diameter hydraulic cylinder. The diesel engine includes a two-stage air filtration system for enhanced protection and can be conveniently cleaned using air from the air compressor.

The unique bump design and centralized control operating system ensure ease of maintenance and operation, making this machine user-friendly and efficient.

This versatile machine can be equipped with either a mud pump or an air compressor drive, making it suitable for both water and steam applications in various working environments..

Our second-hand machinery rivals the quality of new machines, yet comes at a significantly lower price, offering excellent value for money.
