osch Rexroth Corp. 5/64 Technical data Hydraulic fluid For extensive information on the selection of hydraulic fl uids and application conditions please consult our data sheets RA 90220 (mineral oils), RA 90221 (ecologically acceptable fl uids) and RA 90223 (HF-fi re resistant fl uids). The variable pump (A)A4VSO is suitable for operation on HF-fl uids. (HFA, HF, and HFC: EA4VSO or A4VSO...F HFD: standard version A4VSO with FK seals) However, limitations to the technical data, according to RA 90223 must be observed. On certain selected HFC-fluids, pump sizes 125...355, executed in accordance to RA 92053 can be operated with the same pressures and speeds as on mineral oil. On operation with HFA and HF-fl uids, limitations of the technical data must be observed according to RA 90223. On operation with rolling oil (e.g. kerosene + additives) please consult us. When ordering, please state the fl uid to be used. Operating viscosity range Within the operating viscosity range between 80...450 SUS (16...100 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 80...170 SUS (16...36 mm 2 /s) referred to tank temperature (open circuit). Limit of viscosity range For critical operating conditions the following values apply: ν min = 60 SUS (10 mm 2 /s) for short periods (t < 3 min) at max. permissible case drain temperature t max = 194 F (+90 C). ν max = 4550 SUS (1000 mm 2 /s) for short periods (on cold start, operating viscosity should be below 450 SUS (100 mm 2 /sec) within 15 minutes) t min = 13 F ( 25 C) For detailed information on operation with low temperatures see RA 90300-03-.

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 = 13 F ( 25 C) t max = 194 F (+90 C) Example: at an ambient temperature of X C the operating temperature in the tank is 140 F (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 194 F (90 C).
6/64 osch Rexroth Corp. Technical data earing 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 40 71 125 180 250 recommended flushing flow q Sp gpm (L/min) 0.8 (3) 1.0 (4) 1.3 (5) 1.8 (7) Size 355 500 750 1000 recommended flushing flow q Sp gpm (L/min) 4.0 (15) 5.3 (20) 7.9 (30) 10.6 (40) 2.6 (10) These recommended fl ushing fl ows will cause a pressure drop of approx. 30 psi (2 bar) (series 1) and 45 psi (3 bar) (series 3) between the entrance to port U and the pump case (including the pipe fi ttings).

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 20/18/15 acc. to ISO 4406 is necessary.
