Product Description

Detailed Photos

^{Our company not only specializes in producing and selling new machines, but also boasts an extensive network of high-quality second-hand drilling rigs and air compressors. The benefits of our second-hand machinery include competitive pricing, excellent quality, and remarkable cost-effectiveness.}

1. This is an advanced, multifunctional groundwater drilling equipment designed for various applications such as drilling water wells, agricultural irrigation wells, geothermal wells, and more. It is particularly ideal for water extraction projects in mountainous areas and challenging rock formations.

2. The drill pipe holder is equipped with an automatic pressure maintenance and clamping function. It can seamlessly work with the chuck-type power head to ensure synchronized control, quick responses, and reliable operation. The proprietary drilling rig mud treatment system features a customized high-pressure mud pump, which is lightweight, low-pulse, and adept at handling high solid-phase and circulating mud.

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 branded diesel engine includes a two-stage air filtration system for optimal protection and can be easily cleaned using air from the air compressor.

The unique bump design and centralized control operating system make maintenance and operation straightforward and effortless.

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 across diverse working environments..

It closely matches the quality of a new machine but is significantly more affordable.
