Bosch Rexroth A11V(L)O Series 1x axial piston variable pump. All-purpose high-pressure pump with through drive. Size 40 … 260; nominal 350 bar, maximum 400 bar; open circuit.
The A11VO is Rexroth's high-pressure open-circuit pump for heavy mobile machinery: excavators, wheel loaders, mobile cranes, drilling rigs and forestry equipment where a single pump must deliver high flow at 350 bar continuous. The A11VLO variant adds an integrated impeller (charge pump) on the inlet, which improves suction behaviour at high speed and altitude and lets the pump run faster before cavitation limits apply. Both versions offer power (LR), pressure (DR), load-sensing (LS) and electro-proportional (EP) controls, and the through drive allows a second pump to be mounted for auxiliary circuits.
We stock and source the common frame sizes (40, 60, 75, 95, 130, 145, 190, 260) in complete pump assemblies as well as rotary groups, control valves, charge pumps and seal kits for repair.
What we need to quote: the complete type code (for example A11VLO190LRDS/11R-NZD12K02), rotation direction, shaft type, port configuration, control option and any through-drive requirement. If the nameplate is unreadable, send the machine make and model and photos of the pump and we will identify it.
