Liyuan Hydraulics – Where Power Meets Precision.

In the demanding world of engineering drilling—where performance, precision, and durability are non-negotiable—the hydraulic system serves as the heartbeat of every rig. At the forefront of this critical technology stands Liyuan Hydraulics, a trusted name in fluid power solutions, with its flagship product: the A8VO120LA1KH2/72R axial piston variable displacement pump. Engineered for extreme conditions and optimized for continuous operation, this pump is redefining standards in drilling efficiency and system stability.

Advanced Design for Unmatched Performance

The A8VO120LA1KH2/72R belongs to the renowned A8VO series of variable displacement pumps, featuring a swashplate design that enables smooth, responsive control of flow and pressure. With a nominal displacement of 120 cm³/rev and a robust SAE 7/8" shaft (72R mounting flange), it delivers high power density while maintaining compact integration—ideal for space-constrained drilling rigs.

Key technical highlights include:

• High-pressure capability: Rated for continuous operation up to 350 bar, with peak pressures reaching 400 bar, ensuring consistent performance even under heavy loads.

• Integrated load-sensing and pressure control: Enables real-time adaptation to drilling demands, minimizing energy waste and reducing fuel consumption.

• Enhanced durability: Hardened components, advanced sealing technology, and optimized oil flow paths significantly extend service life in abrasive, high-vibration environments typical of geological exploration and foundation drilling.

Engineered for the Future of Drilling

Liyuan Hydraulics has tailored the A8VO120LA1KH2/72R specifically for rotary drilling rigs, core drilling systems, and deep foundation equipment. Its ability to maintain stable output under fluctuating load conditions translates into smoother rod advancement, reduced tool wear, and higher core recovery rates—critical metrics in mineral exploration and geotechnical projects.

Moreover, the pump’s compatibility with modern electro-hydraulic control systems allows seamless integration with smart drilling platforms, supporting data-driven operations and predictive maintenance strategies that are becoming industry norms in 2026 and beyond.

Sustainability Through Efficiency

In an era where operational sustainability is paramount, the A8VO120LA1KH2/72R contributes significantly to greener drilling practices. By precisely matching hydraulic output to actual demand, it reduces unnecessary energy dissipation, lowering both carbon footprint and total cost of ownership. Field reports indicate up to 15% improvement in fuel efficiency compared to fixed-displacement alternatives—a compelling advantage for contractors operating large fleets.

Conclusion: The Pulse of Modern Drilling

As global infrastructure and resource extraction projects grow in scale and complexity, the need for reliable, intelligent hydraulic solutions has never been greater. With the A8VO120LA1KH2/72R, Liyuan Hydraulics delivers not just a component—but a strategic enabler of productivity, precision, and progress in the drilling sector.

For engineers and fleet managers seeking to elevate performance without compromising on reliability, this pump isn’t just an option—it’s the new standard.
