Product Overview

▔▔

The Bosch Rexroth A10VSO is a medium-pressure, axial piston variable pump designed in a swashplate layout for hydrostatic drives operating in open-circuit systems. Revered worldwide as an industry benchmark, the A10VSO is highly valued for its robust build, outstanding power-to-weight ratio, and highly modular control options.

Key Advantages

▔▔

Highly Variable Flow: Output flow is directly proportional to the drive speed and pump displacement, which can be infinitely adjusted by changing the angle of the internal swashplate.

Whisper-Quiet Operation: Engineered with an optimized housing and port plate design to drastically reduce noise emission during high-pressure cycles.

Excellent Suction Performance: Features superior self-priming capabilities, ensuring steady performance even at cold starts.

Extended Service Life: High-grade materials paired with hydrostatically unloaded cradle bearings result in minimal friction wear and long-term durability.

Modular Control Assembly: Easily pairs with a wide range of control devices (e.g., pressure, flow, and power limiters) to match specific system requirements.

FAQ

▔▔

Q1: What is the main difference between the DR, DFR, and DFLR controller options?

DR (Pressure Control): Acts as a pressure limiter. The pump maintains maximum displacement until the set system pressure is reached, at which point it de-strokes to zero flow while holding that pressure limit.

DFR / DFR1 (Pressure & Flow Control): Also called load-sensing control. It senses load requirements and adjusts pump flow so that it matches user demand, maximizing overall energy efficiency.

DFLR (Pressure, Flow & Power Control): Combines the above and monitors system torque. It reduces pump displacement as pressure rises to ensure the driving electric motor or diesel engine is never overloaded.

Q2: Can an A10VSO pump run with water-containing fluids or synthetic fluids?

Yes, but with limitations. The standard A10VSO is designed primarily for mineral-oil-based hydraulic fluids (HLP). Some sizes (like Size 140) and specially sealed configurations can run on environmentally acceptable or fire-resistant fluids (like HFC or HFDU), but their maximum operating speeds and pressures must be de-rated according to Rexroth's fluid guidelines.
