Product Introduction
A10VSO Axial Piston Pump Global Standard for Open-Circuit Hydraulics
The A10VSO is a variable displacement axial piston pump in swashplate design, engineered for hydrostatic drives in open circuits. Known as the industry benchmark for medium-pressure applications, it delivers reliable performance across machine tools, injection molding machines, presses, and mobile equipment.
Key Features
Swashplate Variable Design: Flow is proportional to drive speed and displacement; steplessly variable from zero to maximum by adjusting the swashplate angle.
High Pressure Capability: Rated pressure 280 bar, peak pressure 350 bar for demanding hydraulic systems.
Excellent Suction Performance: Optimized inlet design ensures consistent performance under self-priming, pressurized reservoir, or charge pump conditions.
Low Noise Operation: Engineered for quiet running—ideal for industrial environments where noise reduction matters.
Long Service Life: Robust construction with high-quality materials ensures durability and reduced downtime.
Compact, High Power Density: Favorable power-to-weight ratio enables installation in space-constrained machine compartments.
100% Through-Drive Capability: Mount additional gear or piston pumps up to the same size—build multi-circuit systems from a single prime mover without a splitter gearbox.
Versatile Control Options: Available with DR (pressure compensator), DFR/DFR1 (load sensing), DRG (remote control), DFLR, and proportional control configurations.
Fast Control Response: Short control times for precise machine movements and improved cycle efficiency.
