5 RE 92050/04.09 A4VSO Series 0, and 30 Bosch Rexroth AG 5/68 Technical data Hydraulic fluid For extensive information on the selection of hydraulic fl uids and application conditions please consult our data sheets RE (mineral oils), RE 9022 (ecologically acceptable fl uids) and RE (HF-fl uids). The variable pump A4VSO is suitable for operation on HF-fl uids. (HFA, HFB, and HFC: EA4VSO or A4VSO...F HFD: standard version A4VSO with FK seals) However, limitations to the technical data, according to RE must be observed. On certain selected HFC-fluids, pump sizes , executed in accordance to RE can be operated with the same pressures and speeds as on mineral oil. On operation with HFA and HFB-fl uids, limitations of the technical data must be observed according to RE On operation with rolling oil please consult us. When ordering, please state the fl uid to be used. Operating viscosity range Within the operating viscosity range between mm 2 /s the units can be operated without limitations of the technical data. In order to obtain optimum effi ciency and service life, we recommend that the operating viscosity (at operating temperature) be selected in the range ν opt = opt. viscosity range mm 2 /s referred to tank temperature (open circuit). Limit of viscosity range For critical operating conditions the following values apply: ν min = 0 mm 2 /s for short periods (t < 3 min) at max. permissible case drain temperature t max = +90 C. ν max = 000 mm 2 /s for short periods (on cold start, operating viscosity should be below 00 mm 2 /sec within 5 minutes) t min = 25 C For detailed information on operation with low temperatures see RE B. Selection diagram Viscosity ν (mm 2 /s) VG22 VG32 VG68 VG VG t min = 25 C Fluid temperature range t max = + 90 C otes on the selection of hydraulic fluid In order to select the correct fl uid, it is necessary to know the operating temperature in the tank (open circuit) in relation to the ambient temperature. The hydraulic fl uid should be selected so that within the operating temperature range, the viscosity lies within the optimum range (ν opt ); see shaded section in the selection diagram. We recommend, that the higher viscosity grade is selected in each case. Temperature range (see selection diagram) t min = 25 C t max = + 90 C Example: at an ambient temperature of X C the operating temperature in the tank is 60 C. In the optimum viscosity range (ν opt ; shaded area), this corresponds to grades VG 46 or VG 68; select: VG 68. Important: The case drain temperature is infl uenced by pressure and speed and is always higher than the tank temperature. However the max. temperature at any point in the system may not exceed 90 C νopt 6 Temperature t ( C)

6 6/68 Bosch Rexroth AG A4VSO Series 0, and 30 RE 92050/04.09 Technical data Bearing flushing For the following operating conditions bearing fl ushing is required for a safe, continuous operation: Applications with special fl uids (non mineral oils) due to limited lubricity and narrow operating temperature range Operation at critical conditions of temperature and viscosity with mineral oil Flushing is recommended with vertical mounting (drive shaft facing upwards) in order to ensure lubrication of the front bearing and shaft seal. Flushing is carried out via port U, located in the front fl ange area of the pump. The fl ushing fl uid fl ows through the front bearing and leaves the pump together with the case drain fl ow. Depending on pump size, the following fl ushing fl ows are recommended: Size recommended q Sp flushing flow L/min Size recommended q Sp flushing flow L/min These recommended fl ushing fl ows will cause a pressure drop of approx. 2 bar (series ) and 3 bar (series 3) between the entrance to port U and the pump case (including the pipe fi ttings). otes regarding series 30 When using external bearing fl ushing the throttle screw at port U must be turned in to the end stop. Case drain pressure The permissible case drain pressure (housing pressure) is dependent on the drive speed (see diagram). Case drain pressure pl abs [bar] speed n [rpm] ax. case drain pressure (housing pressure) p L abs max Size bar absolute These are approximate values; under certain operating conditions a reduction in these values may be necessary. Direction of flow S to B. Filtration of the fluid (Axial piston unit) The fi ner the fi ltration, the better the achieved cleanliness of the fl uid and the longer the life of the axial piston pump. To ensure a reliable functioning of the axial piston unit, a minimum cleanliness class of 20/8/5 acc. to ISO 4406 is necessary.

Universal through drive On pump sizes all through drives are supplied as universal through drives U. These have the advantage, that they can be adapted later on. Simply by exchanging the adapter fl ange and the shaft coupler it is possible to convert the through drive option. The conversion sets must be ordered separately, see RE Combination pumps Independent circuits are available for the user when further pumps are built on.. If the combination consists of 2 Rexroth axial piston pumps, and if this must be factory mounted, the two individual type codes must be joined by a +. Ordering example: A4VSO 25 DR / 30 R PPB3K33 + A4VSO 7 DR / 0 R PZB300 2 If a gear or a radial piston pump must be factory mounted as the second pump please consult us.
