Technical data Hydraulic fluid
Notes on the choice of hydraulic fluid
Before starting project planning, please refer to our data sheets RE 90220 (mineral oil) and RE 90221 (environmentally acceptable hydraulic fluids) for detailed information regarding the choice of hydraulic fluid and application conditions.
In order to select the correct hydraulic fluid, it is necessary to know the operating temperature in the reservoir (open circuit) in relation to the ambient temperature.
When using environmentally acceptable hydraulic fluids, the limitations regarding technical data and seals must be observed. Please contact us. When ordering, indicate the hydraulic fluid that is to be used. Operating viscosity range For optimum efficiency and service life we recommend that the operating viscosity (at operating temperature) be selected in the range nopt = opt. operating viscosity 16 ... 36 mm /s 2
referred to reservoir temperature (open circuit). Limits of viscosity range For critical operating conditions the following values apply: 10 mm2/s short-term (t ≤ 1 min) at max perm. case drain temperature of 90 °C.
nmin =
The hydraulic fluid should be selected so that within the operat ing temperature range, the viscosity lies within the optimum range (nopt), see shaded section of the selection diagram. We recommend to select the higher viscosity grade in each case. Example: at an ambient temperature of X °C the operating temperature is 60 °C. In the optimum operating viscosity range (nopt; shaded area) this corresponds to viscosity grades VG 46 resp. VG 68; VG 68 should be selected. Important: The case drain temperature is influenced by pressure and input speed and is always higher than the reservoir 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. If the above conditions cannot be met, due to extreme operat ing parameters please contact us.
Please also ensure that the max. 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.
Filtration of the hydraulic fluid The finer the filtration the better the cleanliness level of the hydraulic fluid and the longer the service life of the axial piston unit.
Depending on the installation situation, special measures are necessary at temperatures between -40 °C and -25 °C. Please contact us.
In order to guarantee the functional reliability of the axial piston unit it is necessary to carry out a gravimetric evaluation of the hydraulic fluid to determine the particle contamination and the cleanliness level according to ISO 4406. A cleanliness level of at least 20/18/15 must be maintained. At very high hydraulic fluid temperatures (90 °C to maximum 115 °C), a cleanliness level of at least 19/17/14 according to ISO 4406 is necessary.
For detailed information on operation with low temperatures see data sheet RE 90300-03-B.
If the above cleanliness levels cannot be maintained, please contact us.

This will supply control fluid directly to the stroke piston; a minimum control pressure of pst ≥ 50 bar is required.
X
The variable pump can only be switched between Vg max or Vg min.

DR – Pressure control The pressure control limits the maximum pressure at the pump output within the pump control range. The variable pump only supplies as much hydraulic fluid as is required by the consum ers. If the operating pressure exceeds the pressure setpoint set at the integrated pressure valve, the pump will adjust towards a smaller displacement and the control deviation will be reduced. The pressure can be set steplessly at the control valve.

ED – Electro-hydraulic pressure control If there is a change at the consumer (load pressure), the position of the control piston changes. This causes an increase or decrease in the pump swivel angle (flow) in order to maintain the electrically set pressure level. The pump thus only delivers as much hydraulic fluid as the consumers can take. The desired pressure level can be set steplessly by varying the solenoid current. When the solenoid current signal drops towards a zero value, the maximum output pressure is limited to pmax by an adjust able hydraulic pressure cut-off (secure fail safe function in case of a loss of power e.g. for use as fan drives). The response time characteristic of the ED-control was optimized for the use as a fan drive system. When ordering, state the type of application in clear text.

Combination pumps A10VO + A10VO
Before finalizing your design request a certified installation drawing. Dimensions in mm.
When using combination pumps it is possible to have multiple, mutually independent circuits without the need for a splitter gearbox. When ordering combination pumps the model codes for the first and the second pump must be joined by a "+". Order example: A10VSO100DFR1/31R-VSB12K04+ A10VSO45DFR/31R-VSA12N00 If no further pumps are to be factory-mounted, the simple type code is sufficient.Included in the delivery contents of the pump with through drive are then: coupling and seal, with plastic cover to prevent penetration by dust and dirt. It is permissible to use a combination of two single pumps of the same size (tandem pump), considering a dynamic mass acceleration force of maximum 10 g (= 98.1 m/s2) without an additional support bracket. Each through drive is plugged with a non-pressure-resistant cover. Before commissioning the units, they must therefore be equipped with a pressure-resistant cover. Through drives can also be ordered with pressure-resistant covers. Please specify in clear text. For combination pumps comprising more than two pumps, the mounting flange must be calculated for the permissible moment of inertia. Permissible mass moment of inertia NG

Installation instructions General
Below-reservoir installation (standard)
The axial piston unit must be filled with hydraulic fluid and air bled during commissioning and operation. This must also be observed following a longer standstill as the axial piston unit empty via the hydraulic lines.
Below-reservoir installation means the axial piston unit is installed outside of the reservoir below the minimum fluid level.
1
Especially with the installation position "drive shaft upwards" or "drive shaft downward", attention must be paid to a com plete filling and air bleeding since there is a risk, for example, of dry running.
2 a min SB
ht min h min
The case drain fluid in the motor housing must be directed to the reservoir via the highest case drain port (L1, L2, L3).
a min
L
For combinations of multiple units, make sure that the respec tive case pressure in each unit is not exceeded. In the event of pressure differences at the case drain ports of the units, the shared case drain line must be changed so that the minimum permissible case pressure of all connected units is not exceed ed in any situation. If this is not possible, separate case drain lines must be laid if necessary.
L S

To achieve favorable noise values, decouple all connecting lines using elastic elements and avoid above-reservoir installa tion.

a min
In all operating conditions, the suction line and case drain line must flow into the reservoir below the minimum fluid level. The permissible suction height hS is a result of the overall pressure loss, but may not be greater than hS max = 800 mm. The minimum suction pressure at port S must also not fall below 0.8 bar absolute during operation.

Installation instructions Above-reservoir installation
Inside-reservoir installation
Above-reservoir installation means the axial piston unit is installed above the minimum fluid level of the reservoir. To prevent the axial piston unit from draining, a height differ ence hES min of at least 25 mm at port L 1 is required in installa tion position 6.
Inside-reservoir installation is when the axial piston unit is nstalled in the reservoir below the minimum fluid level. The axial piston unit is completely below the hydraulic fluid.
Observe the maximum permissible suction height hS max = 800 mm. A check valve in the case drain line is only permissible in indi vidual cases. Consult us for approval.
5
If the minimum fluid level is equal to or below the upper edge of the pump, see chapter "Above-reservoir installation". Axial piston units with electrical components (e.g. electric con trol, sensors) may not be installed in a reservoir below the fluid level.
