Rexroth A10VSO100 Series 31 Axial Piston Pump
Hydraulic unit for high-flow industrial and construction systems
In real hydraulic systems, A10VSO100 is usually not selected at the early design stage. It appears later when engineers realize that multiple hydraulic functions are drawing flow at the same time and smaller units cannot keep system pressure stable.
100 cc/rev displacement is commonly matched with open circuit systems working around 280 bar rated pressure and up to 350 bar peak conditions. These values are not treated as fixed limits in practice but as design reference points during system sizing.
What usually matters in application is how the pump behaves when hydraulic demand is not stable. In heavy machinery, lifting, driving, and auxiliary functions may run together, and this is where A10VSO100 is typically introduced into the system.
You will normally find this model in concrete pump trucks, large construction machinery, and industrial hydraulic stations where continuous multi-actuator operation is expected rather than single-cycle work.
Field engineering observation
During commissioning, this displacement level is often chosen when system response becomes unstable under simultaneous actuator load conditions.
FAQ
When does a system usually need A10VSO100?
When multiple hydraulic functions start affecting pressure stability at the same time, especially under load overlap.
Is this pump only for large machinery?
Not strictly. It depends more on hydraulic demand than machine size classification.
Why is displacement more important in this model?
Because it directly affects whether the system can maintain flow during peak simultaneous operation.
What should be checked during system matching?
Valve configuration and flow distribution design, especially in multi-actuator setups.
