What are the key performance features of the A10VSO Series?
- Multi-Displacement & Control Options: 6 displacement sizes (18-140 cm³/rev) and 3 control types (Dfr1/Dflr/Dr) cover most medium-to-high pressure hydraulic system needs.
- High Efficiency: Axial piston structure with precision-machined cylinder block and valve plate ensures volumetric efficiency ≥95% and mechanical efficiency ≥92%, reducing energy loss.
- Stable High-Pressure Operation: Reinforced housing and wear-resistant piston rings (alloy steel material) support long-term work at 350 bar max pressure, with minimal pressure fluctuation.
- Energy-Saving Design: Variable displacement adjusts flow output based on system load; Dflr control type with load-sensing function further reduces power consumption by 25-30%.
- Low Noise: Optimized swashplate design and hydraulic damping structure reduce noise to ≤78 dB(A) (for small models) and ≤82 dB(A) (for large models) at rated speed.
- Easy Installation & Replacement: Standardized mounting dimensions and port sizes ensure compatibility with existing systems; interchangeable with Rexroth A10VSO series.
