The application and supply of A20VO and A20VLO series axial piston pumps—high-performance hydraulic solutions widely used in construction, industrial, and energy machinery.
These pumps share a robust internal structure centered on three core components: rotating assemblies, variable displacement mechanisms, and the swashplate with supporting bearings. The plunger cylinder body, working in tandem with the drive shaft, efficiently converts mechanical input into hydraulic power. Displacement is precisely controlled through an adjustable swashplate, actuated either hydraulically or electronically, ensuring optimal performance under varying load conditions.
A key distinction lies in their control systems. The A20VO series employs an electric proportional control valve with armature-driven adjustment, enabling highly accurate and responsive displacement control—ideal for applications requiring dynamic regulation. In contrast, the A20VLO series utilizes hydraulic or mechanical feedback mechanisms, offering a simpler, more durable design suited for high-load, continuous-duty environments.
Commonly deployed models include:
A20VO60DFR1/10R-VSD24K68-SO200: 60 mL/rev displacement, 350 bar nominal pressure (400 bar peak), designed for multi-circuit construction equipment.
A20VO95DRS/10R-NZD24N00: 95 mL/rev, 35 bar, suitable for standard hydraulic stations.
A20VLO190DRS/10R-NZD24NOO: 190 mL/rev, 31.5 MPa operating pressure, compatible with water-ethylene glycol fluids.
A20VLO260DRS/10R-NZD24NOO: High-capacity 260 mL/rev model, also rated at 31.5 MPa, serving demanding applications in chemical and energy sectors.
A20VLO95DRS/10R-NZD24N00: Compact 20 mL/rev version for low-displacement station use.
