| Series | A10VSO Series Variable Piston Pumps (Series 31) | |
| Specifications | 28,45,71,100,140 | |
| Working pressure | Rated pressure: 28 MPa, | |
| Peak pressure: 35 MPa | ||
| Control mode: | Characteristic | All-purpose medium pressure pump
'- Axial piston variable pump with swashplate structure is used for hydrostatic transmission in open circuit. |
| DG - Two-Point Direct Control | - Flow is proportional to transmission speed and displacement. | |
| DR- Pressure Control | - By adjusting the angle of the rotating swashplate, the stepless change of flow rate can be realized. | |
| DRG - Remote Pressure Control | - Two shell outlets. | |
| DFR, DFR1 - Pressure and Flow Control | - Excellent oil absorption characteristics. | |
| DFLR - Pressure, Flow and Power Control | - Low noise level. | |
| ED-Electric Hydraulic Control | - Long service life. | |
| - Axial and radial load capacity of transmission shaft. | ||
| - Ideal power-weight ratio. | ||
| - Various control ranges. | ||
| Short control time. | ||
| The pump is driven by a through shaft, and can be loaded with gear pumps or axial piston pumps less than or equal to the same specifications, that is, 100% through shaft drive. |

Safety instructions
- A10VSO pump is designed for use in open circuit.
- The project planning, assembling and commissioning of the axial piston unit must be carried out by qualified personnel.
- Before using the axial plunger unit, please read the corresponding manual completely.
- If necessary, please ask Bosch Rexroth for these handbooks.
- During and shortly after operation, there may be a risk of burning of the axial piston unit (especially the electromagnet). Appropriate safety measures (such as wearing protective clothing) should be taken.
- According to the different working conditions (working pressure, oil temperature) of the axial piston unit, the characteristics may change.
- Work pipeline oil outlet:
· 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).
· Work pipeline nozzles and functional nozzles are only designed for hydraulic pipelines.
- Pressure cut-off and pressure control do not provide overvoltage protection. Separate relief valves are provided in the hydraulic system.
- The data and instructions contained here must be followed.
- The product has not been certified as a department that meets the requirements of DIN EN ISO 13849's general machine safety concept.
- The following tightening torque is used:
· Connector:
Refer to manufacturer's instructions for tightening torque of the joints used.
· Installation bolts: For installation bolts that meet the ISO metric thread standard of DIN 13 and the thread standard of ASME B1.1, we recommend that tightening torque be checked separately according to VDI 2230.
· Thread holes in the axial plunger unit:
The maximum allowable tightening torque MG Max is the maximum value for threaded holes and shall not exceed that value.
· Locking screw:
For the metal locking screw provided with the axial plunger unit, the tightening torque MV is required.
