Product Description

Detailed Photos

^{Our company not only produces and sells new machines, but also boasts an expansive network of second-hand drilling rigs and air compressors. The benefits of our pre-owned machinery are unbeatable: competitive prices, outstanding quality, and exceptional cost-effectiveness.}

1. This is a supremely efficient and versatile groundwater drilling apparatus, optimized for diverse applications such as water wells, agricultural irrigation wells, geothermal wells, and more. It excels especially in water intake projects within mountainous regions or rocky terrains.

2. The drill pipe holder features an automatic pressure maintenance and clamping mechanism, seamlessly integrating with the chuck-type power head for synchronized control, rapid response, and enhanced safety. Our proprietary mud treatment system leverages a bespoke high-pressure mud pump, characterized by its lightweight and minimal pulse, effectively managing high solid phase mud and circulating mud.

The machine is powered by a high-torque hydraulic motor power head and a branded diesel engine. The hydraulic control system employs a large diameter hydraulic cylinder. The branded diesel engine is equipped with a two-stage air filtration system for added protection, and can be directly cleaned using air from the air compressor.

Featuring a unique bump design and centralized control operating system, this machine ensures ease of maintenance and operation.

 

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

Our second-hand units are nearly comparable to new machines in quality, yet significantly more affordable.
