1. High Efficiency & Stable Performance
The triplex piston design provides smooth fluid flow with reduced pressure pulsation, ensuring efficient and consistent mud circulation during drilling.
2. Strong Pressure Capability
Designed to handle high working pressures, making it suitable for deep and complex drilling operations across oil, gas, and water wells.
3. Durable and Heavy-Duty Construction
Built with high-strength materials for critical components such as the crankshaft, cylinder liners, and pistons, which ensures long service life and reliability in harsh environments.
4. Compact Design and Low Noise
The compact structure reduces the machine footprint, while the balanced triplex operation ensures lower vibration and noise, improving overall worksite safety and comfort.
5. Easy Maintenance and Low Operating Cost
Modular design and standardized components make it easy to disassemble, inspect, and replace parts, reducing downtime and maintenance costs.
6. Flexible Speed and Stroke Adjustment
The pump allows adjustable stroke speed to meet different drilling requirements and optimize mud flow and pressure.

Suitable for oil & gas drilling, geothermal energy, mineral exploration, and water well drilling - both onshore and offshore.
8. Compatibility with Various Mud Types
Capable of pumping different drilling fluids including water-based, oil-based, and polymer-based muds.
1. Oil and Gas Exploration Drilling
Used to circulate drilling fluid to cool the drill bit, remove cuttings, and maintain wellbore stability during oil and gas well drilling operations.
2. Geothermal Drilling
Supports high-temperature and high-pressure fluid circulation required for geothermal energy extraction projects.
3. Water Well Drilling
Ideal for deep water well drilling, providing consistent mud flow to transport cuttings and maintain borehole integrity.
4. Mining and Mineral Exploration
Applied in mineral core drilling and exploratory boreholes, especially where high drilling efficiency and fluid pressure are needed.
5. Coalbed Methane (CBM) Drilling
Used in CBM wells to circulate drilling fluid and remove formation debris effectively.
6. Directional and Horizontal Drilling (HDD)
Provides the necessary fluid pressure for non-vertical borehole drilling, such as in urban construction or utility pipeline projects.
7. Shale Gas and Tight Gas Drilling
Capable of handling the high pressure and volume needs of unconventional gas resource drilling.
8. Offshore Drilling Rigs
Used in offshore platforms for deep-sea well development, where reliable and continuous mud flow is critical.
