Maximum pressure 400 bar

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 take 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.

Details regarding the choice 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 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.
