4 4/36 osch Rexroth Corporation (A)A10VO RA A/07.09 Technical Data Hydraulic fluids Prior to project design, please see our technical data sheets RE (mineral oil), RE (environmentally acceptable fluids) and RE (HF-fluids) for detailed information on fluids and operating conditions. When using HF- or environmentally acceptable fluids attention must be paid to possible limitations of the technical data, if necessary contact us. (when ordering please state in clear text the fluid to be used). For operation on kydrol fluid please consult us. Operating viscosity range For optimum efficiency and service life we recommend that the operating viscosity be chosen in the range of: n opt = opt. operating viscosity U ( mm 2 /s) referred to tank temperature (open circuit). imit of viscosity range For critical operating conditions the following values apply: n min = 60 U (10 mm 2 /s) for short periods (t 1 min) at max. permissible case drain temperature of 195 F (90 C). Please note, that the max fluid temperature of 195 F (90 C) is also not exceeded in certain areas (for instance bearing area) The fluid temperature in the bearing area is approx. 7 F (5 K) higher than the average leakage fluid temperature. n max = 4640 U (1000 mm 2 /s) for short periods (t 1 min) on cold start (t min = p 435 psi (30 bar), n 1000 rpm, -13 F (-25 C)) At temperatures between -13 F (-25 C) and -40 F (-40 C) special measures may be required, depending on installation conditions. Please consult us for further information. For detailed information on operation with low temperatures see data sheet RE election diagram Viscosity n U (mm 2 /s) F C VG 68 VG 46 VG 32 VG 22 VG 100 U mm 2 /s mm 2 /s C F U 42 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. The fluid should be selected so that within the operating temperature range, the viscosity lies within the optimum range (n opt ), see shaded section of the selection diagram. We recommend to select the higher viscosity grade in each case. Example: at an ambient temperatue of C the operating temperature in the tank is 140 F (60 C). In the optimum viscosity range (n opt ; shaded area) this corresponds to viscosity grades VG 46 resp. VG 68; VG 68 should be selected Important: The leakage fluid (case drain fluid) temperature is influenced by pressure and input speed, and is always higher than the tank temperature. However, at no point in the circuit may the temperature exceed 195 F (90 C). If it is not possible to comply with these conditions because of 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 4406 is required. If above mentioned grades cannot be maintained please consult us. t min = -40 F (-40 C) Temperature t in F ( C) t max = 240 F (115 C)

This will supply control fluid directly to the stroking piston; a minimum pressure of p st 725 psi (50 bar) is required. The pump can only be switched between V g max or V g min. Please note, that the required control pressure at port is directly dependent on the actual operating pressure p in port (see control pressure diagram).

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 pump supply. The differential pressure at the DRG-control spool is set as standard to 290 psi (20 bar). This results in a pilot fluid flow to the relief valve of approx. 0.4 gpm (1,5 /min) at port. If another setting is required (range from 145 and 320 psi (10 to 22 bar)) please state in clear text. As a separate relief valve we can recommend: DDH 6 (hydraulic) to RE or DETR-O 381 with orifice dia inch (0,8 mm) in P (electric) to RE The max. lenght of piping should not exceed 6.6 ft (2 m). chematic DRG size 18 up to 100 not included in supply tatic characteristic at n 1 = 1500 rpm; t fluid = 122 F (50 C) operating pressure p psi (bar) etting range Hysteresis and pressure rise p max ize not included in supply Flow q v [gpm (/min)] Ports Outlet port Inlet port, 1 Case drain port ( 1 plugged) Pilot pressure port Controller data Hysteresis and repetitive accuracy p max. 45 psi (3 bar) Pressure increase, max NG p psi (bar) (4) (4) (6) (8) (10) (12) Maximum pilot fluid consumption of 0.8 gpm (3 /min) Flow loss at q Vmax see page 9.

31 RA A/07.09 (A)A10VO osch Rexroth Corporation 31/36 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 overhang moment 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-K68). 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 Permissible overhang moment static T m lb-ft (Nm) dynamic at 10g (98.1 m/s 2 )) T m lb-ft (Nm) Weight m lbs (kg) To center of gravity 1 in (mm) 369 (500) 37 (50) 26.5 (12) 3.54 (90) 649 (880) 65 (88) 33 (15) 4.33 (110) 1010 (1370) 101 (137) 46 (21) 5.12 (130) 1593 (2160) 159 (216) 73 (33) 5.91 (150) 2213 (3000) 221 (300) 99 (45) 6.30 (160) 3319 (4500) 332 (450) 132 (60) 6.30 (160) l 1 m 1 m 2 m 3 l 1, l 2, l 3 distance to center of gravity [in (mm)] m 1, m 2, m 3 weight of pump [lbs (kg)] l2 l 3 Tm = (m 1 l 1 + m 2 l 2 + m 3 l 3 ) Tm = (m 1 l 1 + m 2 l 2 + m 3 l 3 ) [lb-ft] [Nm] Overview of attachments Through drive - A10V()O Mounting option second pump Through drive Flange Coupler for Code A10V()O/31 A10V()O/52 (53) Gear pump available on size (AE-J744) splined shaft ize (shaft) ize (shaft) 82-2 (A) 16-4 (5/8 in) K01 18 (U) 10 (U) (18 (U)) eries F 18 to (3/4 in) K52 18 (, R) 10 () (18 (, R)) eries F 18 to () 22-4 (7/8 in) K68 28 (, R) 28 (, R) eries N, G 28 to (U, W) 1) 45 (U, W) 1) 25-4 (1 in) K04 28 (, R) 45 (, R) 28 to (, R) 63 (U, W) 2) (C) 32-4 (1 1/4 in) K07 71 (, R) 85 (U, W) 3) 71 to (U) 3) 38-4 (1 1/2 in) K () 85 () 100 to (4-bold D) 44-4 (1 3/4 in) K () 140 1) Not with K68-through drive on main pump size 28 2) Not with K04-through drive on main pump size 45 3) Not with K07-through drive on main pump size 71

32 32/36 osch Rexroth Corporation (A)A10VO RA A/07.09 Installation instructions General The pump housing must be filled with fluid and air bleeded during commissioning and operation. This is also to be observed, following a longer standstill period as the system may empty via the hydraulic lines. Especially with the installation position drive shaft upwards or drive shaft downwards attention must be paid to a complete filling and deaeration, since there is a risk, that the bearings and shaft seal run dry and overheat. The highest of the case drain ports must be connected to tank with piping material for standard pressure rating suitable for the port size. In order to obtain the lowest noise level, all connections (inlet, outlet, and case drain line) must be linked by flexible members to the tank. Also, avoid above-tank installation. In case of a combination pump with different case drain pressures make sure, that each pump has it s own case drain line to tank. In all operating states, the suction line and case drain line must flow into the tank below the minimum fluid level (h t min = 7.87 in (200 mm)). The permissible suction height h is a result of the oveall pressure loss, but may not be greater than h max = in (800 mm). Under static and dynamic loading the suction pressure at port may not be below p abs min = 12 psi (0.8 bar) absolute. Installation position ee the following examples 1 to 15. Recommended positions: 1 and 3. Other installation positions are also possible, please consult us. Mounting below the reservoir (tandard) Mounting below the reservoir means, that the pump is mounted below the minimum fluid level. The pump can be mounted next to or below the reservoir. 1 F min. 7.87in (200mm) 2 min. 7.87in (200mm) F 3 5 min. 7.87in (200mm) 4 min. 7.87in (200mm) min. 7.87in (200mm) F F F h t min h t min h min h min h t min h min h t min h min h t min h min Position Air bleed Filling 1, 3 and 5 F +, 1 (F) 2 and 4 F +, 1 (F) Above reservoir Installation above the reservoir means, that the pump is mounted above the minimum fluid level.

36 36/36 osch Rexroth Corporation (A)A10VO RA A/07.09 General instruction The pump A10VO was designed for operation in open loop circuits ystems design, installation and commissioning requires trained technicians or tradesmen. e sure to read the entire operating instructions throughly and completely befor using the axial piston unit. If necessary, request them at Rexroth. 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 IO 68 we recommend to check the permissible tightening torques in each individual case to VDI Plugs: for the metal plugs, supplied with the axial piston unit the following min. required tightening torques M V apply (see table).
