If HFD or environmentally acceptab-le hydraulic fluids are being used, the limitations regarding technical data and seals mentioned in RE 90221 and RE 90223 must be ordering, please indicate the used hydraulic viscosity rangeFor optimum efficiency and service life, select an operating vis-cosity (at operating temperature) within the optimum range of opt = optimum operating viscosity 16 to 36 mm2/sdepending on the tank temperature (open circuit).

7 Limits of viscosity rangeThe limiting values for viscosity are as follows: min = 5 mm2/s Short-term (t < 3 min) At max. perm. temperature of tmax = +115 C. max = 1600 mm2/s Short-term (t < 3 min) At cold start (p 30 bar, n 1000 rpm, tmin = -40 C). Only for starting up without load. Optimum operating viscosity must be reached within approx. 15 that the maximum hydraulic fluid temperature of 115 C must not be exceeded locally either ( in the bearing area). The temperature in the bearing area is depending on pressu-re and speed up to 5 K higher than the average case drain measures are necessary in the temperature range from -40 C and -25 C (cold start phase) , please contact us. For detailed information about use at low temperatures, see RE diagramtmin = -40 Ctmax = +115 C-40 -25 -10 10 30 50 90 115 70 0 51040602010020040060010001600-40 0 20 40 60 80 100 -20 1600 22VG 32VG 46VG 68VG 1005 Hydraulic fluid temperature rangeTemperature t in CViscosity in mm2/sDetails regarding the choice of hydraulic fluidThe correct choice of hydraulic fluid requires knowledge of the operating temperature in relation to the ambient temperature: in an open circuit the tank hydraulic fluid should be chosen so that the operating vis-cosity in the operating temperature range is within the optimum range ( opt.)

8 See the shaded area of the selection diagram. We recommended that the higher viscosity class be selected in each : At an ambient temperature of X C an operating tem-perature of 60 C is set. In the optimum operating viscosity range ( opt; shaded area) this corresponds to the viscosity classes VG 46 and VG 68; to be selected: VG note: The case drain temperature, which is affected by pressure and speed, is always higher than the tank temperature. At no point in the system may the temperature be higher than 115 the above conditions cannot be maintained due to extreme operating parameters, please contact finer the filtration, the higher the cleanliness level of the hyd-raulic fluid and the longer the service life of the Axial Piston unit.

9 To ensure functional reliability of the Axial Piston unit, the hyd-raulic fluid must have a claenliness level of at least 20/18/15 according to ISO very high hydraulic fluid temperatures (90 C to max. 115 C, not permitted for sizes 250 to 1000) at least cleanliness level 19/17/14 according to ISO 4406 is the above classes cannot be observed, please contact Data6/64 Bosch Rexroth AGA11VO Series 1 RE 92500 DataOperating pressure rangeInletAbsolute pressure at port S (suction port)Version without charge pumppabs min _____ barpabs max _____ 30 barIf the pressure is > 5 bar, please with charge pumppabs min _____ barpabs max _____2 barMaximum permissible speed (speed limit)Permissible speed by increasing the inlet pressure pabs at the suction port S or at Vg Vg max1, 20,80,91, 00,91, 01,1pabs = 1 barSpeed nmax /nmax1 Displacement Vg / Vg maxpabs = barOutletPressure at port A or BNominal pressure pN _____ 350 barMaximum pressure pmax _____ 400 barNominal pressure: Max.
