Hydraulic fluidsPrior to project design, please see our technical data sheets RE 90 220 (mineral oil), RE 90 221 (environmentally accep-table fluids) and RE 90 223 (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 Skydrop fluid is only possib-le after consultation with us.

Operating viscosity rangeFor optimum efficiency and service life we recommend that the operating viscosity be chosen in the range of:

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

referred to tank temperature (open circuit).

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

νmin = 10 mm2/s for short periods (t ≤ 1 min) at max. permissible leakage oil temperature of 115 °C.

Please note, that the max. fluid temperature of 115 °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.

νmax = 1600 mm2/s for short periods (t ≤ 1 min) on cold start (tmin = p ≤ 30 bar, n ≤ 1000 rpm, -25 °C)

At temperatures between -25 °C and -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 90 300-03-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 (νopt), 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 60 °C . In the optimum viscosity range (νopt; 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 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 hydraulic 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.

At very high operating temperatures (90 °C to max. 115 °C) a cleanliness of

19/17/14 to ISO 4406 is necessary.

If above mentioned grades cannot be maintained please con-sult us.

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 9.

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-spool is set as standard to 20 bar, and this results in a pilot flow of approx. 1,5 l/min. If another setting is required (range between 10 and 22 bar), 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 dia. 0,8 in P (electric) to RE 29 166

The max. lenght of piping should not exceed 2 m.

DRF (DFR) and DRS (DFR1) - pressure and flow control

Execution of control valve as described on page 9 and 10 .

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 (DFR1) valve has no connection between X-port and pump housing.

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

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

When ordering please state the max. pump input torque in clear text.

Control data

For technical data of pressure control see page 9.

For technical data of pressure and flow control see page 11.

Pilot oil consumption max. approx. 3,0 L/min Flow loss at qV max see page 8

Combination pumps A10VO + A10V(S)OCombination pumps offer the possibility to obtain mutually independent hydraulic circuits without the use of a splitter gearbox .

When ordering combination pumps the model codes for the first and the second pump must be joined by a "+" .

Ordering example: A10VO85DFR1/52R-VSC12K04 + A10VO45DR/52R-VSC11N00

If the second pump is not factory mounted, the simple type designation is sufficient. In this case the delivery of the pump with through drive will include: a shaft coupler and a plastic cover to prevent dirt from entering the through drive opening.

Permissible overhang momentIt is permissible to use a combination of two single pumps of the same size (tandem pump) considering a mass acceleration force of max. 10 g (9,81 m/s2) without an additional support bracket.

Overall pressure loss

∆ptot = ∆p1 + ∆p2 + ∆p3 ≤ (1 – pabs min) = 0,2 bar

∆p1: press. loss in pipe due to acceleration of fluid column

Optional installation position.The pump housing must be filled with fluid during commissioning and operation. In order to obtain a low noise level, all connections (inlet, outlet, pilot pressure and case drain lines) must be linked by flexible members to tank. Avoid placing a check valve in the case drain line.

The highest of the case drain ports (L; L1 or L2) must be con-nected to tank with piping material for standard pressure rating suitable for the port sizes.

Vertical installation (Shaft end upwards)

Arrangement inside the reservoir

Before installation fill pump housing, keeping it in a horizontal position. a) If the min. fluid level is equal to or above the pump mounting face: plug port „L" , „L1" and „S“ open; it is recommended to pipe „L1“ and connect a suction pipe to „S“ (see fig. 1).

b) If the min fluid level is below the pump mounting face: pipe ports „L1" and „S" acc. to fig. 2 „L" plugged. (see also limit of conditions)

Note: to avoid pump damage, remove all protective parts (dust covers, plastic plugs etc.) before installation.

Horizontal installationThe pump must be installaed in such a manner, that either „L"; „L1" or „L2“ is at the top.

Arrangement inside the reservoir

a) If the min. fluid level is above the top of the pump: plug port „L1" , „L" and „S" open; it is recommended to pipe „L“ and connect a suction pipe to „S“ (see fig. 3)

b) If the min. fluid level is even with or below the top of the pump: pipe „L" and „S" acc. to fig. 4, „L1" plugged. (see also limit of conditions)

Note: to avoid pump damage, remove all protective parts (dust covers, plastic plugs, etc), before installation.

Arrangement outside the reservoir

Fill pump housing before commissioning.

Pipe port „S" and the highest of the case drain ports „L" „L1" or „L2“ .

a) Mounting above the tank: see fig. 4. (see also „Limit of conditions“)

Arrangement outside the reservoirAbove the reservoir as in fig. 2. Before installation fill pump housing, keeping it in a horizontal position.

Limit of conditions

Min. pump inlet pressure pabs min = 0,8 bar under static and dynamic conditions. Note:try to avoid mounting above tank in order to obtain a low noise level. The permissible suction height is a result of the overall pres-sure loss but my not exceed hmax = 800 mm (immersion depth ht min = 200 mm).
