Notice    Note the project plHangZhou notes on page 59.    In addition to the type code, please specify the rel- evant technical data when placing your order.

Hydraulic fluids Hydraulic fluids

The A10V(S)O 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 plHangZhou:    95710: CZPT ulic fluids based on mineral oils and related hydrocarbons    95711: CZPT ally acceptable hydraulic fluids    95712: HFD hydraulic fluids (for permissible technical data, see data sheet 95715)

Notes on selection of hydraulic fluid The hydraulic fluid should be selected such that the operat- ing viscosity in the operating temperature range is within the optimum range (νopt see selection diagram). Notice At no point of the component may the temperature be higher than 115 °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 respon- sible member of staff at Bosch CZPT .

Note the detailed information on operation with low tempera- tures, see data sheet 90300-03-B

Continuous operation   ν = 400 to 10 mm2/s

this corresponds, for VG 46 for example, to a temperature range of +5 °C to +85 °C (see selection diagram)

θ = -25 °C to +110 °C

Filtration of the hydraulic fluid Finer filtration improves the cleanliness level of the hydrau- lic fluid, which increases the service life of the axial piston unit. A cleanliness level of at least 20/18/15 is to be maintained according to ISO 4406. At very high hydraulic fluid temperatures (90 °C to maxi- mum 115 °C), cleanliness level 19/17/14 according to at least ISO 4406 is necessary. Please contact us if the above classes cannot be observed.
