FluidsPrior 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 ). Operation on Skydrol fluid is only possible after consultation with us.

Operating viscosity rangeFor optimum efficiency and service life we recommend that the operating viscosity (at operating temperature) be selected " the range

nopt = optimum operating viscosity 16 ... 36 mm2/s

referred to tank temperature (open circuit).

Limit of viscosity rangeFor critical operating conditions the following values apply:

nmin = 10 mm2/s for short periods (t ≤1 min) at max. perm. fluid temperature of 90 °C.

Please note that the max. leakage fluid temperature of 90 °C is also not exceeded in certain areas (for instance bearing area).The fluid temperature in the bearing area is approx. 5 K higher than the average leakage fluid temperature

nmax = 1000 mm2/s for short periods (t ≤1 min) on cold start (p ≤30 bar, n ≤ 1500 rpm, tmin = -25 °C)

At temperatures between -40 °C and -25 °C special measures are required, 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 witin the operating tempe-rature 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 tem-perature in the tank is 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 oil (case drain oil) temperature is influ-enced by pressure and input speed and is always higher than the tank temperature. However, at no point in the circuit may the temperature exceed 90 °C.

If it is not possible to comply with the above conditions becau-se of extreme operating parameters or high ambient temperatu-res please consult us.

Filtration of fluidThe finer the filtration the better the achieved cleanliness of the pressure fluid and the longer the life of the axial piston unit.

To ensure a reliable functioning of the axial piston unit, a mini-mum cleanliness of

20/18/15 to ISO 4406 is necessary.

DG - Two Point, Direct Control

The pump can be set to a minimum swivel angle by connecting an external switching pressure to port X.

This will supply the control piston directly with control oil, a minimum pressure of pSt ≥ 50 bar is required.

The pump can only be switched between Vg max or Vg min .

It must be considered, that the required control pressure at port X is directly dependent on the operating pressure pB (see control pressure diagram below).

Control pressure pSt in X = 0 bar ̂ = Vg max

Control pressure pSt in X ≥ 50 bar ̂ = Vg min

The max. permissible control press. amounts to pSt = 280 bar.

DR - Pressure Control

The pressure control serves to maintain a constant pressure in the hydraulic system, within the control range of the pump. The pump therefore supplies only the amount of hydraulic fluid required by the actuators. The pressure can be steplessly set at the pilot valve.

DRG - Pressure Control, Remote

The DRG-control valve enables a remote setting of max. pump pressure, below the setting of the DR-control spool, see page 10.

For the remote setting of pressure it is necessary to pipe an external relief valve to port X. This valve is not included in the supply of the pump.

The differential pressure at the DRG-control spool is set as standard to 20 bar, and this results in a pilot oil flow of approx. 1,5 L/min. If another setting is required, please state this in clear text.

We recommend that one of the following is used as the sepa-rate relief valve:

– DBDH 6 (hydraulic) to RE 25 402 or

– DBETR -SO381 with orifice Ø 0,8 in P (electric) to RE 29 166

Max. lenght of piping should not exceed 2 m.

DRF/DRS - Pressure and Flow Control

Execution of control valve as described on page 10 and 11.

In addition to the pressure control function, the pump flow to the actuator may be varied by means of a differential pressure (eg. over an orifice or a directional control valve). The pump supplies only the amount of fluid as required by the actuator.The pressure control overrides the flow control function.

The DRS-valve has no connection between X port and pump housing.

LA... - Pressure, Flow, and Power Control

Set up of pressure control DR, see page 10. Set up of flow control valve like DRS, see page 12.

In order to achieve a constant drive torque with varying ope-rating pressures, the swivel angle and with it the output flow of the axial piston pump is varied in such a manner, that the product of flow and pressure remains constant.

Flow control is possible below the limit of the power curve.

Combination pumps A10VSO + A10VSOWhen using combination pumps it is possible to have multiple, mutually independent hydraulic 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 "+".

Ordering example: A10VSO100DR/32R-VPB32UB8 + A10VSO71DRF/32R-VSA12N00

Permissible overhang momentIt is permissible to use a combination of two single pumps of the same size (Tandempump), considering a mass acceleration force of 10 g (10x9,81 m/s2) without an additional support bracket.

Installation NotesGeneralThe pump housing must be filled with fluid and air bleeded during commissioning and operation. This is also to be observed, following a longer standstill periode as the system may empty via the hydraulic lines.

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 all operating states, the suction line and case drain line must flow into the tank below the minimum fluid level (ht min = 200 mm).

The permissible suction height h is a result ot the oveall pressure loss, but may not be greater than hmax = 800 mm. Under static and dynamic loading the suction pressure at port S may not be below pabs min = 0,8 bar absolute.

Overall pressure loss

Dp = Dp1 + Dp2 + Dp3 ≤(1 - pabs min) = 0,2 bar

Pressure loss in pipe due to acceleration of fluid column

Dp1 =r• l • dvV • 10-5 [bar]

r= density [kg/m3]

dt l = pipe lenght [m]

Pressure loss due to static head Dp2 = h • r• g • 10-5 [bar]dv/dt = change in fluid velocity inlet [m/s2]

h = height [m]

Dp3 =Line losses (Elbows, etc.)

[bar]g = acceleration due to gravity = 9,81 m/s2

Instalation positionFolowing installation positions are permissible. The shown piping represents the pipe run in principle.

Below-tank installation (standard)

Below-tank installation is present, if the pump is installed below the minimum fluid level. The pump can be installed beside, in or under the tank.

The data specified above only serve to describe the product. No statements concerning a certain condition or suitability for a certain application can be de-rived from our information. The information given does not release the user from the obligation of own judgment and verification. It must be remembered that our products are subject to a natural process of wear and aging.

Subject to change.

General Notes– The A10VSO pump is designed to be used in open loop circuits.

– Project planning, assembly, and startup of the motor require the involvement of trained personnel.

– The working and functional ports are only designed to accommodate hydraulic piping.

– Tightening torques: The tightening torques specified in this data sheet are maximum values and may not be exceeded (maxi-mum value for screw thread). Manufacturer specifications for the max. permissible tightening torques of the used fittings must be observed! For DIN 13 fastening screws we recommend checking the tightening torque individually according to VDI 2230 Edition 2003.

– The housing temperature rises during and shortly after operation. Take suitable safety precautions (e.g. wear protective clothing).

– The data and information contained herein must be adhered to.
