Preservation: Up to 12 months as standard Up to 24 months long-term (state in plain text when ordering) Features of the ATE version The ATE version is an advanced development of the A10VSO for compliance with Directive 94/9/EC (ATE). External features distinguishing it from the standard pump are the ground terminal, the Ex marking and the CE marking on the name plate. Information When ordering, please state which equipment group, category, explosion group, temperature class and ignition protection type are required for your planned ATE application. Potential equalization: The pump must be grounded. For grounding points, please refer to the drawings starting on page 12. Compared to the standard pump, there are restrictions in the technical data relating to temperature, case pressure and bearing flushing / installation position. In order to avoid mechanically generated sparks from contaminants made of aluminum with iron oxide and/ or particles of rust of the surface 4), the pump is painted as standard with corrosion protecting. Please state the required color when ordering. The service life of the bearings must be calculated. The load cycle forms the basis for this.

4 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 (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 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] VG 22 VG 32 VG 68 VG 46 VG ν opt Fluid temperature range t min = -20 C t max = +90 C osch Rexroth AG, RE /

5 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 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 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 / , osch Rexroth AG

11 Axial piston variable pump A10VSO Series 31 DRG Pressure control remotely operated 11 DRG Pressure control remotely operated For the remote-controlled pressure control, the target pressure can be set using a separately arranged pressure relief valve. Pressure control DR see page 10. A pressure relief valve can be externally piped to port for remote setting of pressure below the setting of the DR control valve spool. This relief valve is not included in the scope of supply of the pump. The differential pressure at the DRG control valve is set as standard to 20 bar. At port the amount of control fluid is about 1.5 l/min. If a different setting (range 10 to 22 bar) is required, please state in plain text.

28 28 A10VSO Series 31 Axial piston variable pump Combination pumps A10VSO + A10VSO Dimensions [mm] Combination pumps A10VSO + A10VSO y using combination pumps, it is possible to have independent circuits without the need for splitter gearboxes. 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. Through drives can also be ordered with pressure-resistant covers. Please specify in clear text. L 1 m 1 m 1 m 1, m 2,... Weight of pump [kg] l 1, l 2,...

32 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 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 Horb a.n., Germany Phone info.ma@boschrexroth.de This document, as well as the data, specifications and other information set forth in it, are the exclusive property of osch Rexroth AG.
