series | A11VO Axial Piston Variable Pump | |
Specifications | 40,60,75,95,130,145,190,260 | |
Series 1 | ||
Working pressure | Common pressure 400 bar (40 Mpa), peak pressure 450bar (45 Mpa) | |
Control mode: | Characteristic | The swashplate axial piston variable pump is used for hydrostatic transmission in open loop hydraulic system. |
LR power control DR Constant Voltage Control | Mainly designed for the application of walking machinery. | |
HD hydraulic control, related to pilot pressure | ||
EP proportional control | Under the condition of tank pressurization or using optional built-in injection pump (impeller), the pump operates under the condition of automatic starting oil injection. | |
Provide various control options to meet various application requirements. | ||
The power control options are adjustable externally, even when the pump is running. | ||
The through-axle drive is suitable for adding gear pump and axial piston pump, that is 100% through-axle drive. | ||
The output flow is proportional to the driving speed and can vary steplessly between qV Max and qV min = 0. |

Safety instructions
- A11VO pump is designed for use in open circuit.
- Project planning, assembly and commissioning of axial plunger components must be carried out by qualified personnel.
- Work pipeline nozzles and functional nozzles are only designed for hydraulic pipelines.
- Axial plunger components (especially electromagnets) may be at risk of burning during and shortly after operation. Appropriate safety measures (such as wearing protective clothing) should be taken.
- According to the different working conditions (working pressure, oil temperature) of the axial plunger element, the characteristics may change.
- Pressure nozzle:
Oil nozzles and fixed threads are designed for maximum specified pressure. Machine or system manufacturers must ensure that the safety factor of connecting components and pipes meets the specified working conditions (pressure, flow, hydraulic oil, temperature).
- The data and instructions contained here must be followed.
- The following tightening torque is used:
· Thread holes of axial plunger elements:
The maximum allowable tightening torque MG Max is the maximum value for threaded holes and shall not exceed that value.
· Connector:
Refer to the manufacturer's instructions for the tightening torque of the joints used.
· Fixed screw:
With regard to the fixed screw meeting DIN 13, we recommend that the tightening torque of the screw be checked separately according to VDI 2230.
· Locking screw:
For the metal locking screw attached to the axial plunger element, the fastening torque MV required for the locking screw is applied.
- The product components have not been certified and approved according to the general machine safety concept of DIN EN ISO 13849.
