RE 91 401/09.00 A2FO Mobile Hydraulics Bosch Rexroth AG 3/20 echnical Data Fluid o review the application of A2FO pumps with the selected hydraulic fluid, detailed fluid compatibility and application data can be found in data sheets RE 90220 (mineral oil), RE 90221 (environmentally acceptable hydraulic fluids) and RE 90223 (fire resistant fluids, HF). he fixed pump A2FO is not suitable for operation with HFA. When using HFB-, HFC-, HFD- or environmentally acceptable hydraulic fluids possible limitations for the technical data have to be taken into consideration. If necessary please consult our technical department (please indicate type of the hydraulic fluid used for your application on the order sheet). Operating viscosity range In order to optain optimum efficiency and service life, we recommend that the operating viscosity (at operating temperature) be selected from within the range: ν opt = operating viscosity 16...36 mm 2 /s referred to the tank temperature (open circuit). Viscosity limits he limiting values for viscosity are as follows: izes 5...200 ν min = 5 mm 2 /s, short term at a max. permissible temperature of t max = 115 C ν max = 1600 mm 2 /s, short term on cold start (t min = -40 C) izes 250...1000 ν min = 10 mm 2 /s, short term at a max. permissible leakage oil temp. of t max = 90 ν max = 1000 mm 2 /s, short term on cold start (t min = -25 C) Please note that the max. fluid temperature is also not exceeded in certain areas (for instance bearing area). At temperatures of -25 C up to -40 C special measures may be required for certain installation positions. Please contact us for further information. election diagram Notes on the selection of the hydraulic fluid In order to select the correct fluid, it is necessary to know the operating temperature in the tank (open circuit) in relation to the ambient temperature. he hydraulic fluid should be selected so that within the operating temperature range, the operating viscosity lies within the optimum range (ν opt ) (see shaded section of the selection diagram). We recommend that the highest possible viscosity range should be chosen in each case. Example: At an ambient temperature of X C the operating temperature is 60 C. Within the operating viscosity range (ν opt ; shaded area), this corresponds to viscosity ranges VG 46 or VG 68. VG 68 should be selected. Important: he leakage oil (case drain oil) temperature is influenced by pressure and pump speed and is always higher than the tank temperature. However, at no point in the circuit may the temperature exceed 115 C for sizes 5 200 or 90 C for sizes 250 1000. If it is not possible to comply with the above conditions because of extreme operating parameters or high ambient temperatures please consult us. Filtration he finer the filtration the better the achieved cleanliness level of the pressure fluid and the longer the life of the axial piston unit. o ensure the functioning of the axial piston unit a minimum cleanliness level of 9 to NA 1638 18/15 to IO/DI 4406 is necessary. At very high temperatures of the hydraulic fluid (90 C to max. 115 C, not permissible for sizes 250 1000!) at least cleanliness level 8 to NA 1638 17/14 to IO/DI 4406 is necessary.

RE 91 401/09.00 A2FO Mobile Hydraulics Bosch Rexroth AG 19/20 Installation and Commissioning Guidelines General At start-up and during operation the pump housing has imperatively to be filled up with hydraulic fluid (filling of the case chamber). tartup has to be carried out at low speed and without load till the system is completely bleeded. At a longer standstill the case may discharge via operating line. At new start-up a sufficient filling of the housing has to be granted. he leakage oil in the housing has to be discharged to the tank via highest positioned case drain port. he min. suction pressure at port should not fall below 0,8 bar absolute. Installation position Optional Installation below tank level Pumps below min. oil level in the tank (standard) Fill up axial piston pump before start-up via highest positioned case drain port (note for the shaft on top installation position: fill until oil starts escaping from air bleed port R or U). Recommendation: Fill up suction lines Installation on top of tank level Pump on top of min. oil level in the tank Actions as installation below tank level Installation position 1 and 2: If the pump is left at standstill for a long period, the oil in the housing chamber may fully drain out through the operating lines (air entering via the shaft seal). Consequently, on restarting, the bearings will be insufficiently lubricated. You should therefore refill the axial piston unit via the highest positioned drain port before restarting (Installation position 2: air bleed via port R or U). Installation position 2 (shaft on top) In this installation position, the bearings will be insufficiently lubricated even if the housing chamber is only partially drained. o prevent oil draining via the drain port, insert a check valve in the drain line (opening pressure 0.5 bar). min. admissible presssure at port (min. suction pressure) Operate pump at low speed (igniton speed) till pump system is completely filled up Minimum immersion depth of the suction line or drain line in the tank: 200 mm (relative to the min. oil level in the tank). 1 1 2 1 2 1 2 0,5 bar * * R(U) 2 R (U) 1 2
