Rexroth A10VSO71 Series 31 Axial Piston Variable Pump
Heavy Mid-Flow Hydraulic Power Unit Component
A10VSO71 is used in hydraulic systems where power demand is no longer in the mid-range category. In many real machines, it is selected when smaller pumps cannot maintain stable output during long working cycles or multi-actuator operations.
Key Technical Parameters
Displacement
71 cc/rev
Rated Pressure
280 bar
Peak Pressure
350 bar
System Type
Open Circuit Hydraulic System
What changes in real operation
Compared with smaller models, this pump keeps output more stable when multiple hydraulic functions run at the same time.
Why it is selected
It is often used when system designers need stronger flow reserve to avoid pressure drop during peak demand.
In construction machinery and industrial equipment, hydraulic systems rarely operate under single-function conditions. A10VSO71 is commonly installed where lifting, driving, and auxiliary actions are executed within the same cycle.
Typical Machine Integration
Excavators, wheel loaders, road construction machinery, and heavy industrial hydraulic stations where continuous multi-actuator operation is required.
Engineering consideration
In system design, A10VSO71 is usually chosen when engineers need to prevent flow starvation during simultaneous hydraulic actions.
FAQ
Is A10VSO71 suitable for continuous heavy-duty use?
Yes, it is commonly used in heavy-duty hydraulic systems with long operating cycles.
What is the main difference compared with smaller models?
It provides higher displacement and better stability under multi-function hydraulic loads.
What type of machinery typically uses this pump?
Construction machinery such as excavators and loaders, as well as industrial hydraulic power units.
Does it require special system design?
It should be matched with appropriate valve and control systems to handle higher flow demand.
