• Mud pump flow: 120–240 L/min
• Engine power: 25–55 kW diesel

Engineering Applications:
Ideal for rural water supply, farmland irrigation, and small civil engineering projects. The crawler-type chassis ensures stability on uneven terrain.

Disc-Type Water Well Drilling Rig

Concept Overview:
This traditional rig combines rotary disc technology with hydraulic drive and positive mud circulation. Suitable for both medium and deep drilling.

Technical Specifications:

• Drilling depth: 100–800m
• Hole diameter: 300–1200mm
• Rated rotary torque: 3200–28000 N·m
• Suitable formations: Soil, sand, cobble, soft rock

Operational Advantages:
Positive mud circulation improves slag removal efficiency and reduces drilling resistance. This rig is widely used for irrigation, dewatering wells, and pile foundation construction.
