Technical dataHydraulic fluidPrior to project design please observe the extensive informa-tion 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 li-mitations 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).
Operating viscosity range
In order to obtain optimum efficiency and service life, we recommend that the operating viscosity (at operating tempera-ture) be selected within the range
nopt = opt. operating viscosity 16 ... 36 mm2/s
referred to the reservoir temperature (open circuit).
Limits of viscosity range
For extreme operating conditions the following limits apply:
nmin = 10 mm2/s short term (t ≤1 min) at max.permissible case drain temperature of 115 °C.
Please note, that the max. case drain temperature of 115 °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.
nmax = 1600 mm2/s short term (t ≤ 1 min) on cold start (p ≤30 bar, n ≤ 1000 rpm, tmin -40 °C)
At temperatures between -40 °C and -25 °C special mea-sures may be required for certain installation positions, please contact us for further information.
For detailed information on operation at very low temperatures see RE 90300-03-B.
Selection diagram
Notes on the selction of 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 hydraulic fluid should be selected so that within the ope-rating temperature range, the operating viscosity lies within the optimum range (nopt) (see shaded section of the selection dia-gram). We recommend that the higher viscosity grade should be selected in each case.
Example: At an ambient temperature of X °C the fluid tempe-rature in the tank is 60 °C. In the optimum viscosity range (nopt; 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. Howe-ver max. temperature at any point in the system may not exceed 115 °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 ISO 4406 is required. At very high operating temperatures (90 °C to max. 115 °C) a cleanliness of 19/17/14 to ISO 4406 is necessary.
If the above mentioned cleanliness classes cannot be met please consult us.

DG – Two point control, directly operatedThe pump can be set to a minimum swivel angle by connecting an external control pressure to port X.
This will supply control fluid directly to the stroking piston; a minimum pressure of pst ≥ 50 bar is required.
The pump can only be switched between Vg max or Vg min.
Please note, that the required control pressure at port X is directly dependent on the actual operating pressure pB in port B. (see control pressure diagram).
Control pressure pst in X = 0 bar Vg max
Control pressure pst in X ≥ 50 bar Vg min
The max. permissible control pressure amounts to pst = 120 bar.

The DR-pressure control (see page 11) is overriding this DRG-remote setting of max. outlet pressure.
A pressure relief valve can be externally piped to port X 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 20 bar. This results in a pilot fluid flow to the relief valve of approx. 1,5 L/min at port X. If another setting is required (range from 10-22 bar) please state in clear text.
As a separate relief valve we can recommend:
DBDH 6 (hydraulic) to RE 25402 or
DBETR-SO 381 with orifice dia. 0,8 mm in P (electric)to RE 29166.
The max. lenght of piping should not exceed 2 m.

In additon to the pressure control function, the pump flow may be varied by means of a differential pressure over an orifice or valve spool installed in the service line to the actuator. The pump flow is equal to the actual required flow by the actuator, regardless of changing pressure levels.
The pressure control overrides the flow control function.
Note The DFR1-valve version has no connection between X and the tank (pump housing). Unloading the LS-pilot line must be possible in the valve system. Because of the flushing function sufficient unloading of the X-line must also be provided.

DFLR – Pressure/flow/power control In order to achieve a constant drive torque with varying opera-ting pressures, the swivel angle and with it the output flow from the axial piston unit is varied so that the product of flow and pressure remains constant.
Flow control is possible below the power control curve.
Static characteristic

Combination pump A10V(S)O + A10V(S)OThe use of combination pumps offers the possibility of inde-pendent pump circuits without the need for a splitter gearbox.
When ordering combination pumps the designations for the 1st and the 2nd pump must be joined by a „+“ sign.
Example: A10VO 100DR/31R-VSC12K07 + A10VO 71DR/31R-VSC12N00
If a gear pump or a radial piston pump must be factory-moun-ted please consult us.
The A10V(S)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 designa-tion 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.
Permissible moment of inertiaIt is permissible to combine two single pumps of the same size (tandem pump) and operate the combination with a max. permissi-ble dynamic acceleration of 10g (98.1 m/s2) without additional support.

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 com-pletely 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 (ht min
= 200 mm). The permissible suction height h depends on the overall suction pressure losses, but may never exceed hS max = 800 mm. The minimum inlet pressure at port S may not fall below the minimum value of pabs min = 0.8 bar under any static or dynamic condition.
Installation position
See the following examples1 to 15 Recommended positions: 1 and 3. Other installation positions may be possible; please consult us..
Mounting below the reservoir (Standard)
This is the case whenever the pump is mounted below the min. fluid level. The pump can be installed next to or underneath the reservoir.
Mounting above the reservoir
Installation above the reservoir means that the pump is mounted above the min. fluid level.The use of a check valve in the case drain line is only permissible in individual cases and only after consulting us.

The pump A10V(S)O was designed for operation in open loop circuits –
Systems 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 perfor- –mance 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 MGMax are maximum values for the female threads in the pump casting and may not be exceeded.
- 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 MV apply (see table)
