Prior to project design, please see our technical data sheets RE 90220 (mineral oil), RE 90221 (environmentally acceptable fluids) and RE 90223 (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).
Operating viscosity rangeFor optimum efficiency and service life we recommend that the operating viscosity be chosen in the range of:
Limit of viscosity rangeFor critical operating conditions the following values apply:
nmin = 60 SUS (10 mm2/s) for short periods (t ≤ 1 min) at max. permissible leakage oil temperature of 239 °F (115 °C).
Please note, that the max fluid temperature of 239 °F (115 °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.
nmax = 7500 SUS (1600 mm2/s) for short periods (t ≤ 1 min) on cold start (p ≤ 435 psi (30 bar), n ≤ 1000 rpm, tmin -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 90300-03-B.
Selection diagram
Notes on the selection of the hydraulic fluidIn 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 (nopt), see shaded section of the selection diagram. We recom-mend to select the higher viscosity grade in each case.
Example: at an ambient temperatue of X °C the operating tem-perature in the tank is 140 °F (60 °C) . In the optimum viscosity range (nopt; 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 239 °F (115 °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 fluidThe 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 (195 °F (90 °C) to max. 239 °F (115 °C)) a cleanliness of 19/17/14 to ISO 4406 is necessary.
If above mentioned grades cannot be maintained please con-sult us.

In order to prevent damage to the pump (through cavitation) it is necesssary to maintain a minimum inlet pressure. This minimum required inlet pressure level depends on the drive speed and the pump displacement. These values do not apply however to the High-Speed version (see table of values on page 7).

Operating pressure pB
Schematic DGThe 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 ≥ 725 psi (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 psi (0 bar) Vg max
Control pressure pst in X ≥ 725 psi (50 bar) Vg min
The max. permissible control pressure is pst = 1740 psi (120 bar).

DRG – Pressure control, remoteSchematic DRG size 18 to 100The 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-spool is set as stan-dard to 290 psi (20 bar), and this results in a pilot flow of approx. 0.4 gpm (1,5 L/min)at port X. If another setting is required(range between 145 and 320 psi (10 and 22 bar)), please state in clear text.
As a separate pressure relief valve we can recommend:
– DBDH 6 (hydraulic) to RE 25 402 or
– DBETR -SO381 with orifice dia. 0.03 inch (0,8 mm) in P (electric) to RE 29 166
The max. lenght of piping should not exceed 6.5 ft (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.

Combination pumps A10VSO + A10VSOThe 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 1. and the 2. pump must be joined by a „+“ sign.
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 overhang momentIt 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 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 (ht 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 hmax = 31.50 in (800 mm). Under static and dynamic loading the suction pressure at port S may not be below pabs min = 12 psi (0.8 bar) absolute.
Installation position
See the following examples 1 to 15. Recommended positions: 1 and 3. Other installation positions are also possible, please consult us.
Mounting below the reservoir (Standard)
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.
Above 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.

General instructionThe pump A10VO was designed for operation in open loop circuits –
Systems design, installation and commissioning requires trained technicians or tradesmen. Be 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 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. 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 ISO 68 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).
