Product Highlights
A4VGAxial Piston Variable Pump | Product Highlights
The A4VG series swashplate axial piston variable pump is purpose-built for closed-circuit hydrostatic transmission, serving as the core power component in mobile machinery hydraulic systems.
Key Advantages:
High Pressure & Power Density: Rated pressure 400–450 bar, peak pressure up to 500 bar — powerful output in a compact design
Stepless Variable Control: Flow is proportional to drive speed and displacement; swashplate angle adjusts steplessly from zero to maximum for smooth reversing through neutral
Integrated Charge System: Built-in charge pump handles charge oil and pilot control supply, simplifying system plumbing
Flexible Configuration: Supports 100% through-drive for tandem pump combinations; available with HW, EP, DA, ET and other control options
Reliable & Durable: High-pressure side relief valve protects against system overload; optimized O-ring sealing; long-life rolling bearings


Applications
Travel drive and implement systems for construction and agricultural machinery — excavators, wheel loaders, road rollers, harvesters, concrete mixer trucks, and more.
