Product Description

Detailed Photos

^{Our company not only produces and sells new machines, but also has an extensive network for second-hand drilling machines and air compressors. The advantages of these pre-owned machines are their affordability, premium quality, and outstanding cost-effectiveness.}

1. This is a high-efficiency, multifunctional groundwater drilling machine, ideal for drilling water wells, agricultural irrigation wells, geothermal wells, and various other types of wells. It excels in water intake projects in mountainous terrains and rocky formations.

2. The drill pipe holder is equipped with an automatic pressure-maintaining and clamping feature, seamlessly integrating with the chuck type power head for synchronized control, quick response, and enhanced safety. Our proprietary drilling rig mud treatment system boasts a customized high-pressure mud pump that is lightweight, produces minimal pulse, and efficiently handles high solid-phase mud and circulating mud.

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

Its unique bump design combined with a centralized control operating system ensures easy maintenance and operation.

Equipped with either a mud pump or air compressor drive, this machine is versatile for both water and steam operations, adapting to various working environments..

Though close in quality to a new machine, the cost is substantially lower, offering a great value for money.
