Product Description

Detailed Photos

^{Our company not only produces and sells new machines, but also possesses a vast network of second-hand drilling and air compressors. The benefits of opting for second-hand machinery include a significantly lower price point, superior quality, and an outstanding cost-performance ratio.}

1. This is a highly efficient and versatile groundwater drilling rig, perfect for drilling water wells, agricultural irrigation wells, geothermal wells, and more. It is particularly ideal for water extraction projects in rugged mountainous areas and difficult rock formations.

2. The drill pipe holder features automatic pressure maintenance and clamping functions, which can be synchronized with the chuck-type power head for quick, safe, and reliable control. Our proprietary mud treatment system, enhanced by a custom high-pressure mud pump, is lightweight, has minimal pulse, and efficiently manages high solid-phase mud and circulating mud.

This machine is equipped with a high-torque hydraulic motor power head and a renowned brand diesel engine. The hydraulic control system includes a large-diameter hydraulic cylinder. The brand diesel engine is protected by a two-stage air filtration system and can also be cleaned directly using air from the air compressor.

Its unique bump design and centralized control operating system make it easy to maintain and operate.

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

It matches the quality of a new machine but at a fraction of the cost, delivering exceptional value for your investment.
