RA 92750-A/06.09Bosch Rexroth Corp.AA10VG5/44Technical DataThe variable pump AA10VG is unsuitable for operation withHFA, HFB and HFC. If HFD or environmentally acceptable hydraulic fluids are being used, the limitations regarding technicaldata and seals mentioned in RE 90221 and RE 90223 mustbe observed.When ordering, please indicate the hydraulic fluid used.Operating viscosity rangeFor optimum efficiency and service life, select an operating viscosity (at operating temperature) within the optimum range ofνopt opt. operating viscosity 80.170 SUS (16.36 mm2/s)depending on the circuit temperature (closed circuit).Limits of viscosity rangeThe limiting values for viscosity are as follows:νmin 42 SUS (5 mm2/s)short term (t 3 min)at max. perm. temperature of tmax 240 F ( 115 C)νmax 7400 SUS (1600 mm2/s)short term (t 3 min)at cold start (p 435 psi / 30 bar, n 1000 rpm,tmin -40 F / -40 C).Only for starting up without load. Optimum operatingviscosity must be reached within approx. 15 minutes.Note that the maximum hydraulic fluid temperature of 240 F (115 C) must not be exceeded locally either (e.g. in thebearing area). The temperature in the bearing area is - depending on pressure and speed - up to 9 F (5 K) higher than theaverage case drain temperature.Special measures are necessary in the temperature range from-40 F to -13 F (-40 C to -25 C) (cold start phase), pleasecontact us.For detailed information about use at low temperatures, seeRE 00)(200)500300200150(100)(60)(40)100807060(20)7400 (1600)4600 (1000)0108VG 66VG 42VG 3VG 22VGBefore starting project planning, please refer to our data sheetsRE 90220 (mineral oil), RE 90221 (environmentally acceptablehydraulic fluids) and RE 90223 (HF hydraulic fluids) for detailedinformation regarding the choice of hydraulic fluid and application conditions.Selection diagramViscosity ν SUS (mm2/s)Hydraulic fluid170(36)νopt.80(16)60 (10)(10)5040(5)-40-2002040608042 (5)120 160 200 240100 140 180 220(-40) (-20)(0)(20) (40) (60) (80) (100) (115)(-30) (-10) (10) (30) (50) (70) (90) (110)Temperature t in F ( C)Details regarding the choice of hydraulic fluidThe correct choice of hydraulic fluid requires knowledge of theoperating temperature in relation to the ambient temperature: ina closed circuit the circuit temperature.The hydraulic fluid should be chosen so that the operating viscosity in the operating temperature range is within the optimumrange (νopt) - the shaded area of the selection diagram. Werecommended that the higher viscosity class be selected ineach case.Example: At an ambient temperature of X F (X C) an operating temperature of 140 F (60 C) is set in the circuit. Inthe optimum operating viscosity range (νopt; shaded area) thiscorresponds to the viscosity classes VG 46 or VG 68; to beselected: VG 68.Please note: The case drain temperature, which is affected bypressure and speed, is always higher than the circuit temperature. At no point in the system may the temperature be higherthan 240 F (115 C).If the above conditions cannot be maintained due to extremeoperating parameters, please consult us.

6/44Bosch Rexroth Corp.AA10VGRA 92750-A/06.09Technical DataFiltrationShaft seal ringThe finer the filtration, the higher the cleanliness level of thehydraulic fluid and the longer the service life of the axial pistonunit.To ensure functional reliability of the axial piston unit the hydraulic fluid must have a cleanliness level of at least20/18/15 according to ISO 4406.Depending on the system and the application, for the AA10VG,we recommendFilter elements β20 100With a rising differential pressure at the filter elements, theβ-value must not deteriorate.Permissible pressure loadingThe service life of the shaft seal ring is affected by the speedof the pump and the case drain pressure. It is recommendedthat the average, continuous case drain pressure at operating temperature 45 psi (3 bar) absolute not be exceeded(max. permissible case drain pressure 90 psi (6 bar) absoluteat reduced speed, see diagram). Short term (t 0.1 s) pressure spikes of up to 145 psi (10 bar) absolute are permitted. Theservice life of the shaft seal ring decreases with an increase inthe frequency of pressure spikes.The case pressure must be equal to or greater than the external pressure on the shaft seal ring.At very high hydraulic fluid temperatures (195 F to max. 240 F /90 C to max. 115 C) at least cleanliness levelSize 63Size 28 45Size 1890 (6)If the above classes cannot be observed, please contact us.For notes on filtration types, see page 38.Operating pressure rangeInputVariable pump (with external supply, E):For control EP, EZ, HW and HDboost pressure (at n 2000 rpm) pSp 260 psi (18 bar)For control DA, DGboost pressure (at n 2000 rpm) pSp 365 psi (25 bar)Boost pump:suction pressure ps min:(ν 140 SUS / 30 mm2/s) 12 psi a (0.8 bar abs.)at cold start, short term (t 3 min) 7.5 psi a (0.5 bar abs.)OutputVariable pump:pressure at port A or B(pressure data according to DIN 24312)Nominal pressure pN 4350 psi (300 bar)Peak pressure pmax 5100 psi (350 bar)Boost pump:peak pressure pSp maxsize 18 365 psi (25 bar)peak pressure pSp max size 28, 45, 63 580 psi (40 bar)Nominal pressure: Max. design pressure at which fatiguestrength is ensured.Peak pressure:Max. operating pressure which ispermissible for short term (t 1s).Perm. pressure pabs. max. psi (bar)19/17/14 according to ISO 4406 is required.75 (5)60 (4)45 (3)Size4530 (2)15 (1)1000200030004000Size285000Speed n in rpmTemperature rangeThe FKM shaft seal ring is permissible for case temperatures of-13 F to 240 F (-25 C to 115 C).Note:For application cases below -13 F (-25 C), an NBR shaft sealring is necessary (permissible temperature range: -40 F to 195 F / -40 C to 90 C).
