In the fast-paced and demanding world of modern engineering, the reliability of hydraulic systems directly impacts project timelines, operational efficiency, and overall safety. For high-pressure, heavy-duty applications such as large construction machinery, mining equipment, and metallurgical systems, the piston pump—often regarded as the "power heart" of the hydraulic system—must deliver exceptional performance, precision, and durability. Liyuan Hydraulic’s independently developed A10VG Series Piston Pumps not only meet these rigorous demands with their outstanding technical capabilities but also stand out through a comprehensive suite of professional services. When you choose the A10VG Series, you are not just investing in a high-performance hydraulic component; you are gaining a trusted partner dedicated to supporting your projects from consultation to completion. Our team is committed to providing expert assistance in product consultation, installation and commissioning, and after-sales maintenance, ensuring your engineering projects proceed smoothly and successfully.

The A10VG Series Piston Pumps from Liyuan Hydraulic are engineered to excel in the most challenging working conditions, making them a cornerstone of efficient hydraulic systems. Built around the core principles of "high-pressure stability, precise regulation, and rugged durability," these pumps incorporate multiple technical innovations to deliver consistent, powerful performance. Key specifications highlight their capabilities: the series boasts a rated working pressure of up to 35MPa and a maximum working pressure of 40MPa, with displacement ranging from 28 to 140mL/r and a stable rated speed of 1000–2800r/min. This robust design ensures they can supply continuous, high-intensity power to large-scale hydraulic systems. For instance, in the main hydraulic system of a large excavator, the A10VG Series Piston Pump rapidly delivers high-pressure oil to drive the boom and bucket during heavy-duty digging operations. Even when faced with hard rock or overloaded conditions, the pump maintains stable pressure, eliminating operational delays caused by insufficient power and significantly boosting digging efficiency.

Precise flow regulation is another standout feature of the A10VG Series. Equipped with variable control technology, the pumps support multiple adjustment methods, including electro-proportional control and hydraulic pilot control, achieving a flow control accuracy of ±1.5%—far exceeding the industry average of ±3% for conventional piston pumps. By adjusting the swashplate angle, the pumps enable stepless flow regulation, adapting seamlessly to the varying flow requirements of different hydraulic system operations. In concrete pump trucks, for example, the A10VG Series precisely matches the flow to the boom’s extension and positioning movements, ensuring smooth boom operation and accurate placement. This eliminates boom sway caused by flow fluctuations, enhancing operational safety and the quality of concrete pouring. Additionally, the pumps deliver exceptional energy efficiency, with a volumetric efficiency of over 95% and a mechanical efficiency exceeding 90%. Compared to traditional piston pumps under the same working conditions, they reduce energy consumption by 8%–12%, translating to substantial long-term energy cost savings for enterprises.

To withstand harsh working environments, the A10VG Series undergoes comprehensive durability enhancements. Critical components such as the cylinder block and pistons are crafted from high-strength alloy steel (38CrMoAlA), treated with nitriding and precision grinding to achieve a surface hardness of over HV900. This ensures excellent wear resistance and corrosion resistance, allowing the pumps to endure frequent load impacts and harsh environmental conditions. The valve plate features a bimetallic composite structure combined with hydrodynamic lubrication design, minimizing friction loss and extending service life. The sealing system uses imported polytetrafluoroethylene (PTFE) seals, which excel in high-pressure, high-and-low-temperature resistance, operating stably within a temperature range of -25℃ to 110℃ with a leakage rate of less than 0.2mL/min—well below industry standards. With an average fault-free operation time of over 12,000 hours, the A10VG Series far surpasses the industry average of 10,000 hours, drastically reducing equipment maintenance frequency and downtime losses.

Thanks to its exceptional high-pressure performance and flexible adaptability, the Liyuan Hydraulic A10VG Series Piston Pump has found widespread application across construction machinery, mining machinery, metallurgical equipment, and marine hydraulic systems. It serves as the "core power source" for hydraulic systems in diverse engineering scenarios, providing strong support for the efficient advancement of projects.

In the construction machinery sector, the A10VG Series is the ideal choice for large excavators, concrete pump trucks, and crawler cranes. During mine stripping or infrastructure foundation excavation, large excavators face heavy, high-frequency digging demands. The A10VG Series’ high-pressure output and stable performance ensure sufficient digging force and rapid response, enhancing operational efficiency. In the pumping system of concrete pump trucks, the pump’s large flow capacity enables continuous high-pressure concrete delivery. Even in long-distance, high-lift pumping scenarios, it maintains stable delivery pressure, preventing pipe blockages and ensuring uninterrupted pouring operations.

Within the mining machinery sector, the A10VG Series is compatible with heavy-duty equipment such as mining excavators, loaders, and crushers. Mining excavators operate in harsh environments with 剧烈 load fluctuations when extracting iron ore, coal, and other mineral resources. The A10VG Series’ impact-resistant design and durability allow it to withstand frequent load shocks, avoiding equipment downtime due to component failure. In the hydraulic drive system of crushers, the pump’s precise flow regulation adjusts crushing force based on material hardness, improving crushing efficiency while reducing mechanical wear on the equipment.

The A10VG Series also plays a crucial role in the metallurgical and marine sectors. In metallurgical applications, such as the rolling mill screw-down system and continuous caster mold oscillation system, the pump’s stable high-pressure output ensures rolling precision and continuous casting process stability, enhancing the quality of steel products. For marine hydraulic systems—including steering gear and cargo winch systems—the pump’s resistance to temperature extremes and vibration enables it to adapt to harsh marine environments, ensuring safe ship navigation and efficient cargo handling. Additionally, in the gate opening/closing systems of large hydraulic engineering projects and the lifting systems of port cranes, the A10VG Series remains a key power component, delivering reliable performance.
