A4VG250 Axial Piston Variable Pump
Ultra-high power closed-loop hydraulic pump for heavy-duty and mining machinery systems
A4VG250 is a 250 cm³/rev axial piston variable displacement pump designed for closed-loop hydrostatic transmission systems, operating at a rated pressure of approximately 350 bar with peak capability up to 400 bar.
It delivers very high hydraulic flow output with stepless control, ensuring stable energy transmission and consistent performance under extreme continuous load conditions in heavy industrial environments.
With a reinforced swashplate mechanism and heavy-duty bearing structure, it provides outstanding durability, high shock resistance, and long service life for ultra-heavy machinery applications.
Application Fields & Equipment Usage
A4VG250 is widely used in large-scale mining equipment such as mining excavators (50–100 ton class), large dump trucks, and hydraulic drilling rigs where continuous high-load operation is required.
In construction machinery, it is commonly applied in heavy-duty excavators, tunnel boring auxiliary systems, and large wheel loaders requiring high hydraulic power and stable multi-action control.
In industrial applications, it is used in steel plant handling equipment, port machinery, and heavy material processing systems where long-duty cycles and high pressure stability are critical.
It is also suitable for specialized engineering vehicles that require maximum hydraulic output under harsh working environments such as high temperature, vibration, and shock loads.
