1. What is the core design and application scope of the A10VNO series pumps?
The A10VNO series is a high-pressure, axial piston variable displacement pump engineered for heavy-duty hydraulic systems. It is widely applied in:
- Construction machinery (excavators, cranes, loaders)
- Industrial machinery (hydraulic presses, injection molding machines)
- Mining equipment (rock drills, conveyor systems)
- Marine systems (deck machinery, steering systems)
- Agricultural machinery (large tractors, harvesters)
- Energy equipment (wind turbine hydraulic control systems)
Models A10VNO45DR/52R-VSC11N00 and A10VNO85DRS/53L-VWC12N00 are optimized for high-pressure, high-flow scenarios requiring precise control and reliable performance under extreme working conditions.
2. How to interpret the model designations of the two pumps?
Breakdown of key model components for clarity:
- A10VNO: Series identifier (Axial Piston Variable Displacement Pump, high-pressure grade)
- 45/85: Nominal displacement (45 cm³/rev / 85 cm³/rev)
- DR/DRS: Control type (DR = Pressure Compensated Control; DRS = Dual Control [Pressure + Flow Compensated])
- 52R/53L: Mounting flange code (52R = SAE B flange; 53L = SAE C flange, per ISO 3019-2)
- VSC11N00/VWC12N00: Configuration code (includes seal type, pressure relief setting, and electrical interface)
3.What are the core features of the A10VNO series pumps?
- High-Pressure Resistance: Robust cylinder block, piston, and valve plate design withstands extreme pressures (up to 40 MPa), ensuring durability in heavy-duty applications.
- Variable Displacement Efficiency: Automatically adjusts displacement based on system demand (via DR/DRS control), minimizing energy consumption and reducing fuel costs.
- Precision Control Performance: Pressure/flow compensation systems provide stable output with minimal fluctuation, improving the accuracy of hydraulic actuators (e.g., cylinders, motors).
- Low Noise Operation: Optimized flow path design and hydraulic balance structure reduce operating noise (≤ 78 dB at 2500 rpm), suitable for both indoor and outdoor use.
- Long Service Life: Hardened steel components (nitrided piston rods, chrome-plated shafts) and anti-wear coatings reduce friction; self-lubricating design extends maintenance intervals.
- Leak-Proof & Corrosion-Resistant: High-temperature resistant Viton seals and aluminum alloy housing (with anti-corrosion treatment) prevent oil leakage and rust.
