Hydraulic Pump A4VG Piston Pump A4VG40 A4VG56 A4VG71 A4VG90 A4VG125 A4VG180 Hydraulic Excavator Pump

A4VG is a classic closed-loop axial piston variable displacement pump, with significant differences in core parameters between different series, as follows:

1, Core parameters of sub series
32 series
The pressure level is 400~450 kilograms, and the displacement covers 28~250. It is the version with the highest proportion of domestic imitations and is suitable for hydraulic systems such as fully hydraulic corn harvesters and port machinery.
35 series
The pressure level ranges from 400 to 530 kilograms, with a significantly increased maximum pressure. Only three displacement options, 56, 71, and 90, are retained. It is designed for walking conditions and is suitable for mobile machinery such as loaders, forklifts, and municipal vehicles.
40 series
The rated pressure is directly increased to 450 kilograms, the displacement covers 112~210, and the speed is increased by 10% compared to the previous generation. It is designed specifically for ultra-high pressure conditions such as concrete pump trucks and is compatible with the hydraulic system of pump trucks.
2, General basic parameters
Some models, such as A4VG180, can support 220V voltage and are compatible with conventional hydraulic systems. The German imported version can be used in most parts of the country.
Large displacement models such as A4VG250 support 380V voltage and a speed of up to 1500r/min, suitable for high-power hydraulic scenarios.
Some models can be customized and adopt an edge vertical installation structure to meet the installation space requirements of different devices.
