The ST 200 Water Well Drilling Rig is a high-efficiency, multi-functional drilling equipment designed for 200-meter depth drilling with up to 305mm hole diameter. It is particularly suitable for water wells, agricultural irrigation wells, ground source heat pump wells, and other well drilling applications, especially in mountainous areas and rock formations.

• Hydraulically driven by diesel engine for powerful performance
• Simple and clear dashboard with easy-to-use controls
• Crawler mounted structure for excellent mobility
• Four standard high legs for stability and easy transportation

The ST 200 is an efficient and multifunctional drilling equipment primarily used for:

• Water well drilling projects
• Agricultural irrigation systems
• Ground source heat pump installations
• Mountainous area water intake projects
• Rock formation drilling operations

The drilling rig features advanced hydraulic technology with large torque hydraulic motor rotation and large-diameter hydraulic cylinder propulsion. The system is powered by a high-quality diesel engine with two-stage air filtration for extended service life. The unique pump unit design facilitates maintenance and reduces operational costs.

• Select appropriate well type: Choose between deep wells, large wells, counterpart pumping wells, foreign wells, and small-diameter tube wells based on groundwater availability
• Reasonable well layout: Arrange well locations according to hydrogeological conditions, avoiding overly dense placement
• Configure appropriate water pump: Match pump specifications to well output and required working head

• Use proper casing to prevent hole collapse
• Begin with low-pressure slow rotation when lowering drilling tools
• Maintain consistent drilling parameters during operation
• Adjust pump volume according to formation characteristics
• Monitor water supply system and pump operation continuously
• Handle core samples carefully to prevent damage or loss
