KC450 Fully Hydraulic Water Well Drilling Rig – High-Power Deep Drilling with Foam Pump for Complex Formation Efficiency (450m Depth)

The KC450 Fully Hydraulic Water Well Drilling Rig is a high-capacity deep drilling solution engineered for large-scale water well, geothermal, and infrastructure projects demanding exceptional power and formation adaptability. Powered by a 110kW Yuchai engine, the KC450 delivers abundant, reliable power that ensures high efficiency and stability throughout the drilling process, enabling rapid completion of deep boreholes while maintaining consistent performance in the most demanding conditions.

A key differentiator of the KC450 is its integrated foam pump system, which injects foaming agent into the drilling fluid to reduce friction, protect downhole tools, and optimize cuttings removal. This foam-assisted drilling technology significantly improves penetration efficiency in complex formations – including loose strata, fractured rock, and water-sensitive clays – where conventional mud circulation may encounter challenges, ensuring smooth project progress even in the most difficult geological conditions.

With 450m maximum drilling depth, 140–350mm hole diameter range, swing torque of 7000–9500 N·m, and a 6.6m one-time advance length, the KC450 is purpose-built for serious deep drilling operations. The rig supports Φ89 and Φ102 drill pipes with 6.0m length options, while the 25T lifting force provides ample capacity for deep-hole pipe handling. Built on a durable steel track undercarriage with a 1.6m high leg stroke for superior stability on uneven terrain, the KC450 delivers the capability, durability, and advanced formation management you need to take on the largest, most challenging deep drilling projects with confidence.
