A4VG110 Axial Piston Pump – High-Torque, High-Performance Drive for Heavy-Duty Hydrostatic Systems
The A4VG110 is a robust, large-displacement variable displacement axial piston pump engineered as the cornerstone of high-power closed-circuit hydrostatic drives. As a key member of the proven A4VG series, it delivers immense torque and precise, responsive control in a reliable package, making it the prime mover of choice for heavy-duty mobile and industrial machinery requiring superior tractive effort and driving force.
Primary Applications & Equipment:
This high-capacity pump is designed for demanding hydrostatic transmission systems in a wide range of powerful equipment:
Heavy Construction & Earthmoving: Large wheel loaders, medium-to-large excavator travel drives, bulldozers, and heavy compactors.
Mining & Material Handling: Underground mining vehicles (LHDs), large forklifts, port machinery, and heavy-duty reach stackers.
Agricultural & Forestry: High-horsepower tractors, combine harvesters, forwarders, and harvesters.
Specialized Industrial Drives: Winch and crane drives, heavy vehicle test stands, and other industrial applications requiring high-torque, variable-speed rotary power.
Core Technologies & Design Features:
High-Power Bent-Axis Design: Leverages the efficient and durable bent-axis principle, scaled for a substantial 110 cm³/rev displacement. This design provides exceptional power density, high mechanical efficiency, and excellent starting torque, essential for moving heavy loads and overcoming high inertia.
Advanced Closed-Circuit Architecture: Purpose-built for high-performance closed-loop systems, enabling infinitely variable speed and torque control of connected hydraulic motors. This allows for smooth acceleration, precise maneuvering, and efficient power management in vehicle drive applications.
Integrated System Solution: Features a built-in gear-type charge pump for supercharging the closed circuit and an integrated valve block. The valve block typically includes cross-port pressure relief valves, a flushing valve for cooling and filtration, and control valves (e.g., for pressure cutoff or power limitation), offering a compact and highly functional all-in-one drive package.
Intelligent & Versatile Control Options: Supports a wide range of control mechanisms, from traditional hydraulic servo controls ("HD" for pressure control) to advanced electro-proportional ("EP") controls. This allows seamless integration into everything from simple lever-operated systems to sophisticated, electronically managed machine control platforms (e.g., via CAN-Bus) for optimal performance and fuel efficiency.
Built for Extreme Duty: Constructed with reinforced components and heavy-duty bearings to withstand the continuous high pressure, shock loads, and harsh environmental conditions typical in heavy machinery, ensuring maximum durability and uptime.
Engineered for Reliable Power & Control:
The A4VG110 is engineered to deliver not just raw power, but also intelligent and controllable power. Its robust design prioritizes serviceability and long-term reliability, translating into lower total cost of ownership for critical equipment.
Key Specifications (Typical):
Series: A4VG (Closed Circuit, Variable Displacement)
