Product details
I. Product Positioning and Core Differences
1. A10VSO Series
• Positioning: A premium open-circuit swashplate-type axial piston pump by Rexroth, designed for high-precision, energy-efficient hydraulic systems.
• Core Advantages:
• Full Displacement Control: Enables stepless flow adjustment via swashplate angle modulation, with displacement ranges covering 18–180 cm³/rev (e.g., A10VSO18 to A10VSO180), catering to light- to heavy-duty applications.
• Energy Efficiency: Supports constant pressure (DR), constant flow (FR), power control (DFLR), and electro-proportional control (ED/ER), reducing energy consumption by over 30%.
• High-Pressure Performance: Rated pressure of 280 bar, peak pressure up to 350 bar, suitable for high-load applications (e.g., injection molding machines, die-casting machines, steel metallurgy equipment).
• Long Service Life: Features hydrostatically unloaded swashplate bearings and FKM fluororubber seals, ensuring extended lifespan; optimized suction design and case drainage reduce noise below industry benchmarks.
2. A10VO Series
• Positioning: A mid-pressure swashplate-type axial piston pump by Rexroth, prioritizing cost-effectiveness and versatility for mobile machinery and industrial equipment.
• Core Differences:
• Displacement Range: Typically covers 16–140 cm³/rev (e.g., A10VO16 to A10VO140), offering slightly fewer options than the A10VSO.
• Control Modes: Supports pressure control (DR/DRG) and pressure-flow composite control (DFR/DFR1), with fewer electro-proportional options.
• Pressure Ratings: Matches the A10VSO with a rated pressure of 280 bar and peak pressure of 350 bar, though some variants may have slightly lower transient pressure capabilities.

III. Typical Applications
1. A10VSO Series
• Industrial: Injection molding machines, die-casting machines, steel metallurgy equipment, machine tool hydraulic systems.
• Engineering: Primary pumps for excavators, cranes, concrete pump trucks, and other mobile machinery requiring high-precision control.
• Specialized Scenarios: Offshore engineering, port machinery, and equipment demanding rigorous control accuracy.
2. A10VO Series
• General Industrial: Light-duty machine tools, woodworking equipment, textile machinery.
• Mobile Machinery: Hydraulic systems for compact excavators, loaders, and agricultural machinery.
• Cost-Sensitive Scenarios: Applications prioritizing affordability over advanced control features.

IV. Selection Guidelines
1. Prioritize A10VSO for:
• Systems requiring full displacement stepless adjustment and high-efficiency control (e.g., constant pressure/power modes).
• Harsh environments (high temperatures, high pressures, corrosive fluids) demanding long-life seals and low-noise operation.
• Budgets allowing for long-term stability and optimized maintenance costs.
2. Consider A10VO for:
• Cost-constrained projects with moderate flow control precision requirements.
• Light- or medium-duty applications needing basic pressure control without complex modes.
• Rapid replacements of legacy systems compatible with A10VO designs.
