Data Sheet of A10VSO Series 32

REXROTH Type Code of A10VSO Series

 

 

 

Axial piston variable pump, A10VSO Series 31 

- All-purpose medium pressure pump
- Sizes 18 to 140
- Nominal pressure 280 bar
- Maximum pressure 350 bar
- Open circuit 

Hydraulic fluids
The A10VSO variable pump is designed for operation with HLP mineral oil according to DIN 51524. Application instructions and requirements for hydraulic fluids should be taken from the following data sheets before the start project planning:
- 90220: Hydraulic fluids based on mineral oils and related hydrocarbons
- 90221: Environmentally acceptable hydraulic fluids
- 90222: Fire-resistant, water-free hydraulic fluids (HFDR/HFDU) (for permissible technical data, see data sheet 90255)
- 90223: Fire-resistant, water-containing hydraulic fluids (HFAE, HFAS, HFB, HFC)
- 90225: Restricted technical data only for operation
- with fre-resistant, water-free and water-containing hydraulic fluids (HFDR, HFDU, HFB, HFC)- technical data

Notes on selection of hydraulic fluid
The hydraulic fluid should be selected so that the operating viscosity in the operating temperature range is within the optimum range (νopt see selection diagram).

Notice
- The axial piston unit is suitable for operation with water
containing HF hydraulic fluid. See version “E”

- For industrial application areas
- Open circuit

Hydraulic fluids
The A10VSO variable pump is designed for operation with HLP mineral oil according to DIN 51524. Application instructions and requirements for hydraulic fluids should be taken from the following data sheets before the start of project planning:

- 90221: Environmentally acceptable hydraulic fluids
- 90222: Fire-resistant, water-free hydraulic fluids (HFDR/HFDU)

Details regarding the selection of hydraulic fluid
The hydraulic fluid should be selected such that the operating viscosity in the operating temperature range is within the optimum range (νopt, see selection diagram).

Note
At no point of the component may the temperature be higher than 90 °C. The temperature difference specified in the table is to be taken into account when determining the viscosity in the bearing.
If the above conditions cannot be maintained due to extreme operating parameters, please contact the responsible member of staff at Bosch Rexroth.
