The following must be taken into account during project planning: 2)

Excessive current levels (I > 1200 mA with 12 V or I > 600 mA with 24 V) to the ER solenoid can result in undesired increase of pressure which can lead to pump or system damage: - Use Imax current limiter solenoids. - A sandwich plate pressure reducing valve can be used to protect the pump in the event of overflow. An accessory kit with sandwich plate pressure reducing valve can be ordered from Rexroth under part number R902490825.

Technical dataHydraulic fluid

Before starting project planning, please refer to our data sheets RE 90220 (mineral oil), RE 90221 (environmentally acceptable hydraulic fluids) and RE 90222 (HFD hydraulic fluids) for detailed information regarding the choice of hydraulic fluid and application conditions.

If environmentally acceptable hydraulic fluids are being used, the limitations regarding technical data and other seals must be observed. Please contact us.

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 80 - 170 SUS (16 ... 36 mm2/s)

referred to reservoir temperature (open circuit).

Limits of viscosity range

For critical operating conditions the following values apply:

nmin = 60 SUS (10 mm2/s) short-term (t ≤ 1 min) at max perm. case drain temperature of 239 °F (115 °C).

Please also ensure that the max. case drain temperature of 239 °F (115 °C) is not exceeded in localized areas (for instance, in the bearing area). The fluid temperature in the bearing area is approx. 7 °F (5 K) higher than the average case drain tempe-rature.

nmax = 7500 SUS (1600 mm2/s) short-term (t ≤ 1 min) on cold start (p ≤ 435 psi (30 bar), n ≤ 1000 rpm, tmin -13 °F (-25 °C))

Depending on the installation situation, special measures are necessary at temperatures between -40 °F (-40°C) and -13 °F (-25°C). Please contact us.

For detailed information on operation with low temperatures see data sheet RE 90300-03-B.

Selection diagram

Notes on the choice of hydraulic fluid

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.

The hydraulic fluid should be selected so that within the ope-rating 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 °F (°C) the operating temperature is 140 °F (60 °C). In the optimum operating vis-cosity 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 239 °F (115 °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 opera-ting parameters please contact us.

Filtration of the hydraulic fluidThe finer the filtration the better the cleanliness level of the hyd-raulic fluid and the longer the service life of the axial piston unit.

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 (195 °F (90 °C) to ma-ximum 239 °F (115 °C)), a cleanliness level of at least 19/17/14 according to ISO 4406 is necessary.

If the above cleanliness levels cannot be maintained, please contact us.

The variable 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 stroke piston; a minimum control pressure of pst ≥ 725 psi (50 bar) is requi-red.

The variable 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 characteristic).

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 consu-mers. 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.

this setting range is the permissible setting range and must not be exceeded. The range of possible settings at the valve are greater.

The DR-control valve (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 delivery contents of the DRG control.

The differential pressure at the DRG control valve is set as standard to 290 psi (20 bar). This results in a pilot oil flow to the relief valve of approx. 0.4 gpm (1.5 l/min) at port X. If ano-ther setting is required (range from 145-320 psi (10-22 bar)) please state in clear text.

As a separate pressure relief valve we can recommend:

DBDH 6 (hydraulic) to RE 25402 or

DBETR-SO 381 with orifice dia 0.03 inch (Ø 0.8 mm) in P (electric) to RE 29166.

The max. length of piping should not exceed 6.5 ft (2 m).

In addition to the pressure control function (see page 11), the pump flow may be varied by means of a differential pressure over an adjustable orifice (e.g. directional valve) 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 version has no connection between X and the reservoir. 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.


Flow control at n1 = 1800 rpm; tfluid = 122 °F (50 °C))



Static characteristic at variable speed

Differential pressure Dp

Standard setting: 200 to 320 psi (14 to 22 bar). If another setting is required, please state in clear text. Relieving the load on port X to the reservoir results in a zero stroke ("standby") pressure which lies about 15 to 30 psi (1 to 2 bar) higher than the differential pressure Dp. System influen-ces are not taken into account.

DFLR – Pressure, flow and power controlExecution of the pressure control like DR(G), see page 11 (12). Execution of the flow control like DFR, DFR1, see page 13.

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 pump is varied so that the product of flow and pressure remains constant.

Flow control is possible below the power control curve.

The power characteristic is set in the factory; when ordering, please state in clear text, e.g. 40 HP (30 kW) at 1800 rpm.

ED – Electro-hydraulic pressure controlThe ED valve is set to a certain pressure by a specified, variable solenoid current.

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 adjustable 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.

Summary mounting options


Combination pumps A10VO + A10VOWhen 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.

It is permissible to use a combination of two single pumps of the same size (tandem pump), considering a dynamic mass accele-ration 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.

Changing connector position

If necessary, you can change the position of the connector by turning the solenoid.

To do this, proceed as follows:

1. Loosen the mounting nut (1) of the solenoid. To do this, turn the mounting nut (1) one revolution counter-clockwise.

2. Turn the solenoid body (2) to the desired position.

3. Retighten the mounting nut of the solenoid. Tightening torque: 4 +0.7 lb-ft (5+1 Nm) (size WAF 26, 12-pt DIN 3124).

On delivery, the position of the connector may differ from that shown in the brochure or drawing.

Installation instructionsGeneral

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.

Particularly with the "drive shaft up/down" installation position, filling and air bleeding must be carried out completely as there is, for example, a danger of dry running.

The case drain fluid in the motor housing must be directed to the reservoir via the highest case drain port (L1, L2, L3).

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 excee-ded in any situation. If this is not possible, separate case drain lines must be laid if necessary.

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

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 = 31.50 in (800 mm). The minimum suction pressure at port S must also not fall below 12 psi (0.8 bar) absolute during operation.

Installation position

See the following examples 1 to 12. Additional installation positions are available upon request.

Recommended installation positions: 1 and 3.

Note

You can expect certain installation positions to affect the –control device. Because of gravity, unit weight and case pressure, minor characteristic displacements and response time changes may occur.

Below-reservoir installation (standard)

Below-reservoir installation means the axial piston unit is ins-talled outside of the reservoir below the minimum fluid level.

Installation instructionsInside-reservoir installation

Inside-reservoir installation is when the axial piston unit is installed in the reservoir below the minimum fluid level. The axial piston unit is completely below the hydraulic fluid.

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 cont-rol, sensors) may not be installed in a reservoir below the fluid level.

hS max Maximum permissible suction height (31.50 in (800 mm))

amin When designing the reservoir, ensure adequate distance between the suction line and the case drain line. This prevents the heated, return flow from being drawn directly back into the suction line.

Above-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 difference hES min of at least 0.98 in (25 mm) at port L 1 is required in installation position 6.

Observe the maximum permissible suction height hS max = 31.50 in (800 mm).

A check valve in the case drain line is only permissible in individual cases. Consult us for approval.
