drives in an open circuit
▶▶ For use in mobile and stationary applications
▶▶ Flow is proportional to the drive speed and displacement.
▶▶ High power density
▶▶ High total efficiency
▶▶ Optimized dimensions for special installation situations
▶▶ Excellent suction characteristics
▶▶ Low noise level
▶▶ Long service life
▶▶ Economical design
▶▶ Through drive for combining additional pumps

Hydraulic fluids
The A4FO fixed 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:
▶▶ 90220: Hydraulic fluids based on mineral oils and related
hydrocarbons
▶▶ 90221: Environmentally acceptable hydraulic fluids
▶▶ 90222: Fire-resistant, water-free hydraulic fluids
(HFDR/HFDU)
▶▶ 90223: Fire-resistant, water-containing hydraulic fluids
(HFC, HFB, HFAE, HFAS)
Sizes 22 and 28 are not suitable for operation with HFA,
HFB and HFC.

Note
At no point of the component may the temperature be higher
than 115 °C (sizes 22 and 28) and 90 °C (sizes 71 to 500).
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.
