4 A10VSO Series 31 Axial piston variable pump Hydraulic fluid Hydraulic fluid Prior to project planning, please refer to the detailed information in our data sheets 90220 (mineral oil) concerning the choice of hydraulic fluid and application conditions. The variable pump A10VSO ATE II 3G ck II T4 can be optionally enabled by special releases for other hydraulic fluids. Operating viscosity range For optimum efficiency and service life we recommend that the operating viscosity (at operating temperature) be selected the range n opt = opt. Operating viscosity 16... 36 mm 2 /s correlating to the reservoir temperature (open circuit). Limits of viscosity range For critical operating conditions the following values apply: n min = 10 mm 2 /s momentary (t 3 min) at maximum permissible drain temperature of 90 C. Please also ensure that the maximum case drain temperature of 90 C is not exceeded in localized areas (for instance, in the bearing area). The fluid temperature in the bearing area is approx. 5 K higher than the average case drain temperature. n max = 1000 mm 2 /s momentary (t 1 min) only for cold start, optimum operating viscosity must be attained within 3 min. (p 30 bar, n 1000 rpm, t min -20 C) Notes on the choice of hydraulic fluid In order to select the correct hydraulic fluid, it is necessary to know the operating temperature in relation to the ambient temperature. In an open circuit this is the reservoir temperature. The hydraulic fluid should be selected so that the operating viscosity in the operating temperature range is within the optimum range (n opt see shaded area of the selection diagram). We recommend, that the higher viscosity grade is selected in each case. Example: At an ambient temperature of C, an operating temperature of 60 C is set in the circuit. In the optimum operating viscosity range (ν opt. shaded area), this corresponds to the viscosity classes VG 46 or VG 68; to be selected: VG 68. Note The case drain temperature, which is affected by pressure and speed, is always higher than the tank temperature. However, at no point in the component may the temperature exceed 90 C. The temperature difference specified on the left is to be taken into account when determining the viscosity in the bearing. Temperature range (cf. selection diagram) t min = -20 C t max = +90 C Selection diagram Viscosity η [mm 2 /s] -40-20 1600 1000 600 400 200 100 60 40 20 10 0 20 40 60 80 90100 1600 VG 22 VG 32 VG 68 VG 46 VG 100 36 16 ν opt. -40 5 5-25-20-10 0 10 30 50 7080 90 115 Fluid temperature range t min = -20 C t max = +90 C osch Rexroth AG, RE 92711-01--2/04.2015

Axial piston variable pump A10VSO Series 31 Hydraulic fluid 5 Ignition temperature of hydraulic fluid The pump is approved for temperature class T4 according to DIN EN 13463-1. Only use hydraulic fluids whose ignition temperature is 185 C. Please contact us if the above conditions cannot be met due to extreme operating parameters. Filtration of the hydraulic fluid Finer filtration improves the cleanliness level of the hydraulic fluid, which in turn increases the service life of the axial piston unit. A cleanliness level of at least 20/18/15 is to be maintained according to ISO 4406. Please contact us if the above classes cannot be observed. Monitoring the operational data Safety instructions To keep the maximum leakage temperature of 90 C at least one of the following measures must be taken and controlled regularly: check the leak oil temperature at port L or L 1 (maximum distance 30 cm) check the suction temperature at maximum 50 C at the suction port check the maximum suction temperature that is determined at the initial operation for the following working points: maximum working pressure and maximum flow maximum working pressure and minimum flow In addition to that a monitoring of the tank filling height is to be made. When the temperature limits are exceeded, suitable countermeasures have to follow. RE 92711-01--2/04.2015, osch Rexroth AG

When ordering combination pumps, the type designations of the 1st and 2nd pump must be linked by a +. Order example: A10VSO100DR/31R-AS12K5+ A10VSO71DR/31R-AS12N00 It is permissible to use a combination of two single pumps of the same nominal size (tandem pump) considering a dynamic mass acceleration of maximum 10 g (= 98.1 m/s 2 ) without additional support brackets. For combination pumps consisting of more than two pumps, the mounting flange must be rated for the permissible mass torque (please consult us). Each through drive is plugged with a non-pressure-resistant cover. efore operating the unit for the first time, close it with a pressure-resistant lid.

32 A10VSO Series 31 Axial piston variable pump Project planning notes Project planning notes The A10VSO ATE II 3G ck II T4 pump is designed to be used in open circuits. The project planning, installation and commissioning of the axial piston unit require the involvement of qualified skilled person. efore using the axial piston unit, please read the corresponding instruction manual completely and thoroughly. If necessary, request these from osch Rexroth. efore finalizing your design, request a binding installation drawing. The specified data and notes must be observed. Pressure controllers are not backups against pressure overload. A separate pressure relief valve is to be provided in the hydraulic system. Depending on the operating condition of the axial piston unit (operating pressure, fluid temperature), the characteristic may shift. Not all versions of the product are approved for use in a safety function pursuant to ISO 13849. Please consult the responsible contact person at osch Rexroth if you require reliability parameters (e.g. MTTF d ) for functional safety. Service line ports: The ports and fixing threads are designed for the specified peak pressure. The machine or system manufacturer must ensure that the connecting elements and lines correspond to the specified operating conditions (pressure, flow, hydraulic fluid, temperature) with the necessary safety factors. The service and function ports are only designed to accommodate hydraulic lines. Safety instructions During and shortly after operation, there is a risk of burns on the axial piston unit and especially on the solenoids. Take appropriate safety measures (e.g. by wearing protective clothing). Moving parts in control equipment (e.g. valve spools) can, under certain circumstances, get blocked in position as a result of contamination (e.g. impure hydraulic fluid, abrasion, or residual dirt from components). As a result, the flow of hydraulic fluid and the build-up of momentum in the axial piston unit can no longer meet the operator's specifications. Even the use of various filter elements (external or internal flow filtering) cannot rule out errors, but can only help minimize risks. The machine/system manufacturer must check whether additional measures are required on the machine for the relevant application in order to bring the powered load into a safe position (e.g. safe stop) and ensure any measures are properly put into practice. osch Rexroth AG Mobile Applications An den Kelterwiesen 14 72160 Horb a.n., Germany Phone +49 7451 92-0 info.ma@boschrexroth.de www.boschrexroth.com This document, as well as the data, specifications and other information set forth in it, are the exclusive property of osch Rexroth AG.
