4/ osch Rexroth AG A10VO eries 31 RE 92711/06.09 Technical data Hydraulic fluid Prior to project design please observe the extensive information on the selection of hydraulic fluids in our data sheets RE 90220 (mineral oil), RE 90221 (ecologically acceptable fluids) and RE 90223 (HF-fluids). When using HF- or ecologically acceptable fluids possible limitations on the technical data may be applicable, if necessary please consult us (when ordering please state the type of fluid to be used in clear text). For operation on kydrol fluid please consult us. Operating viscosity range In order to obtain optimum efficiency and service life, we recommend that the operating viscosity (at operating temperature) be selected within the range n opt = opt. operating viscosity 16... 36 mm 2 /s referred to the reservoir temperature (open circuit). imits of viscosity range For extreme operating conditions the following limits apply: n min = 10 mm 2 /s short term (t 1 min) at max.permissible case drain temperature of 90 C. Please note, that the max. case drain temperature of 90 C is also not exceeded in certain areas (eg. bearing area). The temperature in the bearing area is approx. 5 K higher than the average case drain temperature. n max = 1000 mm 2 /s short term (t 1 min) on cold start (t min = p 30 bar, n 1000 rpm, -25 C) At temperatures between -25 C and - C special measures may be required for certain installation positions, please contact us for further information.

The hydraulic fluid should be selected so that within the operating temperature range, the operating viscosity lies within the optimum range (n opt ) (see shaded section of the selction diagram). We recommend that the higher viscosity grade should be selected in each case. Example: At an ambient temperature of C the fluid temperature in the tank is 60 C. In the optimum viscosity range (n opt ; shaded area) this corresponds to viscosity grades VG 46 or VG 68; VG 68 should be selected. Important The case drain temperature is influenced by pressure and speed and is typically higher than the tank temperature. However max. temperature at any point in the system may not exceed 90 C. If the above mentioned conditions cannot be kept due to extreme operating parameters or high ambient temperatures please consult us. Filtration of fluid The finer the filtration the better the achieved cleanliness of the fluid and the longer the service life of the axial piston unit. In order to ensure a reliable functioning of the axial piston unit it is necessary to determine the fluid cleanliness class through a gravimetric evaluation; a cleanliness level of at least 20/18/15 to IO 46 is required. If the above mentioned cleanliness classes cannot be met please consult us. 36 n opt. 16

36/ osch Rexroth AG A10VO eries 31 RE 92711/06.09 Combination pumps A10VO + A10VO The use of combination pumps offers the possibility of independent pump circuits without the need for a splitter gearbox. When ordering combination pumps the designations for the 1. and the 2. pump must be joined by a + sign. Example: A10VO 100DR/31R-PC12K07 + A10VO 71DR/31R-PC12N00 If a gear pump or a radial piston pump must be factory-mounted please consult us. Permissible moment of inertia The A10V()O axial piston unit can be supplied with a through drive according to the ordering code on page 3. The through drive version is designated by the code numbers (K01-K24). If no other pumps are factory-mounted, the simple type designation is sufficient. The delivery of a pump with through drive includes the shaft coupler, the seal and if applicable an adapter flange. Every through drive is closed with a non protective cover upon delivery. Prior to start up this cover must be replaced by a pressure tight cover (or a 2nd pump). Through drives can be ordered with a pressure tight cover. Please indicate in clear text. It is permissible to combine two single pumps of the same size (tandem pump) and operate the combination with a max. permissible dynamic acceleration of 10g (98.1 m/s 2 ) without additional support. ize 18 28 45 71 100 1 Permissible moment of inertia static T m Nm 500 880 1370 2160 3000 4500 dynamic at 10g (98.1 m/s 2 ) T m Nm 50 88 137 216 300 450 Weight m kg 12 15 21 33 45 60 To center of gravity 1 mm 90 110 130 150 160 160 l 1 m 1 m 2 m 3 l 1, l 2, l 3 To center of gravity [mm] m 1, m 2, m 3 Weight of pump [kg] Tm = (m 1 l 1 + m 2 l 2 + m 3 l 3 ) 1 102 [Nm] l2 l 3
RE 92711/06.09 A10VO eries 31 osch Rexroth AG 37/ Installation instructions General The pump housing must be filled with fluid during commissioning and operation and must be deaerated. This must also be the case after prolonged periods of standstill since the system can empty itself through the hydraulic lines. This is especially important with the mounting position shaft end upwards or downwards : make sure that the housing is completely filled with fluid, to prevent the bearings and shaft seal from running dry and overheating. Connect the highest one of the case drain ports with tubing of the light series wall thickness and the largest size corresponding to the port size. In order to attain the lowest noise level, all connections (suction, pressure, pilot, and case drain) must be linked by flexible members to tank and try to avoid mounting above the reservoir. In case of combination pumps with different case drain pressures it is necessary that each pump has its own case drain line. In every operating condition the inlet and the case drain lines must always enter the reservoir below the minimum fluid level (h t min = 200 mm). The permissible suction height h depends on the overall suction pressure losses, but may never exceed h max = 800 mm. The minimum inlet pressure at port may not fall below the minimum value of p abs min = 0.8 bar under any static or dynamic condition. Installation position ee the following examples1 to 15. Recommended positions: 1 and 3. For more installation position please consult us. Mounting below the reservoir (tandard) This is the case whenever the pump is mounted below the min. fluid level.

/ osch Rexroth AG A10VO eries 31 RE 92711/06.09 General instructions The pump A10VO was designed for operation in open loop circuits ystems design, installation and commissioning requires trained technicians or tradesmen. All hydraulic ports can only be used for the fastening of hydraulic service lines. During and shortly after operation of a pump the housing and especially a solenoid can be extremely hot, avoid being burned; take suitable safety measures (wear protective clothing). Dependent on the operating conditions of the axial piston pump (operating pressure, fluid temperature) deviations in the performance curves can occur. Pressure ports: All materials and port threads are selected and designed in such a manner, that they can withstand the peak pressures. The machine and system manufacturer must ensure, that all connecting elements and hydraulic lines are suitable for the actual operating pressures. Pressure cut off and pressure control are not suitable for providing system protection against excessive pressures. A suitable overall main line relief valve must be incorporated. All given data and information must be adhered to. The following tightening torques are valid: - Female threads in the axial piston unit: the maximum permissible tightening torques M GMax are maximum values for the female threads in the pump casting and may not be exceeded. Value see table below. - Fittings: please comply with the manufacturer s information regarding the max. permissible tightening torques for the used fittings. - Fastening bolts: for fastening bolts to DIN 13 we recommend to check the permissible tightening torques in each individual case to VDI 2230. - Plugs: for the metal plugs, supplied with the axial piston unit the following min. required tightening torques M V apply (see table).
