Rexroth A11VO Variable Displacement Axial Piston Pump
The A11VO series is designed for open-circuit hydraulic systems that require adjustable flow output under changing operating conditions. By varying displacement according to system demand, the pump supports stable hydraulic performance across a wide range of machine applications.
Available in 40cc, 60cc, 75cc, 95cc, 130cc, 145cc, 190cc and 260cc displacements, A11VO pumps are commonly used in construction equipment, agricultural machinery, mining vehicles, drilling systems, hydraulic power units and industrial production equipment.
Typical Installation Scenarios
In mobile machinery, the A11VO is frequently installed as the main hydraulic pump supplying flow to travel drives, boom cylinders, steering systems and auxiliary hydraulic circuits.
In industrial applications, the pump is often integrated into hydraulic power units, forming presses, testing equipment and manufacturing systems where variable flow demand occurs during different operating stages.
Equipment manufacturers typically select A11VO pumps when system flexibility, compact installation dimensions and variable flow control are required within the same hydraulic circuit.
