Bosch Rexroth Axial Piston Fixed Pump A2FO

Features
––Fixed pump with axial tapered piston rotary group of
bent-axis design, for hydrostatic drives in an open circuit
––For use in mobile and stationary applications
––The flow is proportional to the drive speed and displacement
––The drive shaft bearings are designed for the bearing service
life requirements usually encountered in these areas
––High power density
––Small dimensions
––High total efficiency
––Economical design
––One-piece tapered piston with piston rings for sealing

Hydraulic fluid
Before starting project planning, please refer to our data
sheets RE 90220 (mineral oil), RE 90221 (environmentally
acceptable hydraulic fluids), RE 90222 (HFD hydraulic fluids)
and RE 90223 (HFA, HFB, HFC hydraulic fluids) for detailed
information regarding the choice of hydraulic fluid and application
conditions.
The fixed pump A2FO is not suitable for operation with HFA
hydraulic fluid. If HFB, HFC or HFD or environmentally acceptable
hydraulic fluids are used, the limitations regarding technical
data or other seals must be observed.

Filtration of the hydraulic fluid
Finer filtration improves the cleanliness level of the hydraulic
fluid, which increases the service life of the axial piston unit.
To ensure the functional reliability of the axial piston unit, a gravimetric
analysis of the hydraulic fluid is necessary to determine
the amount of solid contaminant and to determine the cleanliness
level according to ISO 4406. A cleanliness level of at
least 20/18/15 is to be maintained.
At very high hydraulic fluid temperatures (90 °C to maximum
115 °C), a cleanliness level of at least 19/17/14 according to
ISO 4406 is necessary.
If the above classes cannot be achieved, please contact us.

Note
The case drain temperature, which is affected by pressure and
speed, can be higher than the reservoir temperature. At no
point of the component may the temperature be higher than
115 °C. The temperature difference specified below 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, we recommend flushing the case at
port U (sizes 250 to 1000).
