A10VO Series Variable Displacement Axial Piston Pump

Highlight Model: AA10VO28DFR/31L-VSC62N00 (Part No.: R910963776)

Core Features & Technical Advantages

• Variable Displacement Adaptability: Each model in the series features an adjustable displacement mechanism, allowing real-time flow control to match dynamic system loads. This flexibility minimizes energy waste, enhances operational efficiency, and ensures consistent performance across varying work conditions—from light-duty cycles to continuous high-demand operations.

• Robust Heavy-Duty Construction: Built with hardened alloy components, precision-machined piston assemblies, and a rugged axial piston design, the A10VO Series withstands extreme operating pressures (rated pressure up to 350 bar, peak pressure up to 400 bar). The corrosion-resistant and wear-resistant build guarantees an extended service life, reducing maintenance frequency and downtime even in harsh industrial or outdoor environments.

• Precision Control & Stability: The flagship AA10VO28DFR/31L-VSC62N00 model is equipped with a VSC62N00 control unit, enabling responsive pressure and flow management for tasks requiring high accuracy. The DFR/31L configuration enhances system stability by minimizing pressure fluctuations, making it ideal for applications such as machine tools, automated production lines, and construction equipment where smooth power transmission is critical.

• Wide Compatibility & Operating Range: Compatible with common hydraulic fluids (mineral oil, synthetic hydraulic oils, and biodegradable fluids), the series operates efficiently within a temperature range of -20°C to 80°C. With a displacement of 28 cm³/rev across all A10VO28 variants, the pumps deliver consistent flow rates tailored to low-to-medium hydraulic system demands, ensuring versatility across industries.

• Low Noise & High Energy Efficiency: Advanced hydraulic circuit design reduces fluid turbulence and mechanical friction, resulting in low noise emissions (≤76 dB(A) at rated speed) and high volumetric efficiency (≥95%). This combination makes the series suitable for indoor industrial settings where noise reduction is a priority, while also lowering long-term energy costs.

• Modular & Interchangeable Design: All A10VO Series models share standardized mounting interfaces (31L configuration aligns with SAE/ISO industry standards) and modular components. This design simplifies installation, replacement, and maintenance, ensuring compatibility with existing hydraulic setups and reducing downtime for upgrades or repairs.

Versatile Industry Applications
