Bosch Rexroth AGRE 91 401/09.07 AFO 3/24

Hydraulic fuid

Beore starting project planning, please reer to our data sheetsRE 90220 (mineral oil), RE 90221 (environmentally acceptablehydraulic uids) and RE 90223 (HF hydraulic uids) or detailedinormation regarding the choice o hydraulic uid and applica-

tion conditions.

The fxed pump A2FO is unsuitable or operation with HFA. IHFB, HFC and HFD or environmentally acceptable hydraulic u-ids are being used, the limitations regarding technical data andseals mentioned in RE 90221 and RE 90223 must be observed.

When ordering, please indicate the used hydraulic uid.

Operating viscosity range

For optimum efciency and service lie, select an operating vis-cosity (at operating temperature) within the optimum range o

opt = optimum operating viscosity 16 to 36 mm2/s

depending on the tank temperature (closed circuit) and tanktemperature (open circuit).

Limits o viscosity range

The limiting values or viscosity are as ollows:

Sizes 5 to 200:

min = 5 mm2/s,short-term (t < 3 min)at max. perm. temperature o tmax = +115C.

max = 1600 mm2/s,short-term (t < 3 min)

at cold start (p 30 bar, n 1000 rpm, tmin = -40C)Only or starting up without load. Optimum operatingviscosity must be reached within approx. 15 minutes.

Sizes 250 to 1000:

min = 10 mm2/s,short-term (t < 3 min)at max. perm. temperature o tmax = +90C.

max = 1000 mm2/s,short-term (t < 3 min)at cold start (p 30 bar, n 1000 rpm, tmin = -25C).Only or starting up without load. Optimum operating

viscosity must be reached within approx. 15 minutes.Note that the maximum hydraulic uid temperature o 115C(90C at size 250 to 1000) must not be exceeded locally either(e.g. in the bearing area). The temperature in the bearing areais - depending on pressure and speed - up to 12 K higher thanthe average case drain temperature.

Special measures are necessary in the temperature range rom-40C and -25C (cold start phase), please contact us.

For detailed inormation about use at low temperatures, seeRE 90300-03-B.

Details regarding the choice o hydraulic fuid

The correct choice o hydraulic uid requires knowledge o theoperating temperature in relation to the ambient temperature: inan open circuit the tank temperature.

The hydraulic uid should be chosen so that the operating vis-cosity in the operating temperature range is within the optimumrange (opt.) - the shaded area o the selection diagram. Werecommended that the higher viscosity class be selected ineach case.

Example: At an ambient temperature o XC an operating

temperature o 60C is set. In the optimum operating viscosityrange (opt; shaded area) this corresponds to the viscosityclasses VG 46 or VG 68; to be selected: VG 68.

Please note:

The case drain temperature, which is aected by pressure andspeed, is always higher than the tank temperature. At no pointin the system may the temperature be higher than 115C orsizes 5 to 200 or 90C or sizes 250 to 1000.

I the above conditions cannot be maintained due to extremeoperating parameters, we recommend ushing the case at portU (size 250 to 1000).

Filtration

The fner the fltration, the higher the cleanliness level o the hy-draulic uid and the longer the service lie o the axial piston unit.

To ensure unctional reliability o the axial piston unit, the hy-draulic uid must have a claenliness level o at least

20/18/15 according to ISO 4406.

At very high hydraulic uid temperatures (90C to max. 115C ,not permitted or sizes 250 to 1000) at least cleanliness level

19/17/14 according to ISO 4406 is required.

I the above classes cannot be observed, please contact us.

Shat seal ring

Permissible pressure loading

The service lie o the shat seal ring is aected by the speed othe pump and the case drain pressure. It is recommended that

the average, continuous case drain pressure at operating tem-perature 3 bar absolute not be exceeded (max. permissible casedrain pressure 6 bar absolute at reduced speed, see diagram).Short term (t < 0.1 s) pressure spikes o up to 10 bar absoluteare permitted. The service lie o the shat seal ring decreaseswith an increase in the requency o pressure spikes.

The case pressure must be equal to or greater than the exter-nal pressure on the shat seal ring.

Installation below the tank

Pump below min. uid level in the tank (standard)

Fill axial piston pump beore startup via the highest casedrain port

Run the pump at low speed until the system is bledcompletely.

Minimum immersion depth o leakage line in tank:200 mm (relative to the min. uid level in the tank).

Additional measures required or installation position 2 (shatacing up): with installation position 2, make sure that thepump case is completely ull beore starting up. Bleed atport R (sizes 10 to 200) resp. U (sizes 250 to 1000). An airpocket in the bearing area is leading to damage o the axialpiston pump.

Recommendation: Fill up suction lines

Installation notesGeneral

The pump case must be completely flled up with hydraulic uid during startup and during operation (flling the case chamber). Thepump must be started up at low speed and no load until the system has been bled completely.

I stopped or an extended period, uid may drain out o the case through the service lines. When restarting, make sure that thecase contains sufcient uid.

The leakage uid inside the case chamber must be drained o to the tank through the highest case drain port. The min. suctionpressure at port S must not all below 0,8 bar absolute (see page 4).

Installation position

Optional.

Installation above the tank

Pump above minimum uid level in tank

Proceed in same way as below the tank installation

Additional measures or installation positions 1 and 2:

I stopped or an extended period, uid may drain out o thecase chamber through the service lines (air enters throughthe shat seal). The bearings will thereore not be properlylubricated when the pump is started up again. Fill the axialpiston pump beore restarting via the highest case drain port.Installation position 2: bleed at port R (sizes 10 to 200) resp.U (sizes 250 to 1000).

Additional measures required or installation position 2 (shatacing up):In this installation position the bearings will not be properlylubricated, even i there is still some uid in the case cham-ber. Putting a non-return valve (opening pressure 0,5 bar) inthe leakage line can prevent the system emptying through

the line. Note: min. admissible pressure at port S (min. suction pres-

sure see page 5)

General Notes The A2FM pump is designed to be used in open and closed circuits.

Project planning, assembly, and commissioning o the pump require the involvement o qualifed personnel.

The service line ports and unction ports are only designed to accommodate hydraulic lines.

During and shortly ater operation, there is a risk o burns on the motor. Take suitable saety precautions, e.g. wear protective

clothing

There may be shits in the characteristic depending on the operating state o the motor (operating pressure, uid temperature).

Tightening torques:- The tightening torques specifed in this data sheet are maximum values and must not be exceeded

(maximum values or screw thread).Manuacturer's instruction or the max. permissible tightening torques o the used fttings must be observed!

- For DIN 13 fxing screws, we recommend checking the tightening torque individually according to VDI 2230 Edition 2003.

The data and inormation contained herein must be adhered to.
