A20VG and A22VG axial piston variable displacement pumps—two key solutions designed to meet the evolving demands of modern hydraulic systems in construction and industrial machinery.
The A20VG is a slant disc axial piston pump engineered for closed-loop circuits, offering stepless displacement adjustment by varying the swashplate angle. This design enables precise control of flow output, supporting high-efficiency operation under a nominal pressure of 280 bar and peak pressure of 350 bar. Its compatibility with multi-loop systems makes it particularly suitable for complex hydraulic applications.
In contrast, the A22VG series is optimized for open-circuit configurations and integrates load-sensing capabilities for enhanced energy efficiency. Models such as the A22VG045HT1005M1/40BRNB2S73FB2S4A-Y are widely applied in equipment like skid steer loaders, where responsive and adaptive hydraulic performance is critical.
Both pump types share a core operating principle—adjusting flow through controlled variation of the swashplate angle—but are tailored to distinct system requirements: A20VG for closed-loop precision, A22VG for open-loop versatility.
Key internal components—including the rotating cylinder block, variable displacement mechanism, swashplate bearings, and integrated control valves—ensure reliable energy conversion, smooth operation, and long service life under demanding conditions.
These pumps are ideally suited for applications in excavators, cranes, and other industrial machinery requiring robust, high-pressure hydraulic drive systems.
