Hydraulic fluidBefore starting project planning, please refer to our data sheets RE 90220 (mineral oil), RE 90221 (environmentally acceptable hydraulic fluids) and RE 90223 (HF hydraulic fluids) for detailed information regarding the choice of hydraulic fluid and applica-tion conditions.

The fixed motor A2FM is unsuitable for operation with HFA. If HFB, HFC and HFD or environmentally acceptable hydraulic flu-ids are being used, the limitations regarding technical data and seals mentioned in RE 90221 and RE 90223 must be observed.

When ordering, please indicate the used hydraulic fluid.

Operating viscosity range

For optimum efficiency and service life, select an operating vis-cosity (at operating temperature) within the optimum range of

νopt = optimum operating viscosity 16 to 36 mm2/s

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

Limits of viscosity range

The limiting values for viscosity are as follows:

Sizes 5 to 200:

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

νmax = 1600 mm2/s, short-term (t < 3 min) at cold start (p ≤ 30 bar, n ≤ 1000 rpm, tmin = -40°C) Only for starting up without load. Optimum operating viscosity must be reached within approx. 15 minutes.

Sizes 250 to 1000:

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

νmax = 1000 mm2/s, short-term (t < 3 min) at cold start (p ≤ 30 bar, n ≤ 1000 rpm, tmin = -25°C). Only for starting up without load. Optimum operating viscosity must be reached within approx. 15 minutes.

Note that the maximum hydraulic fluid temperature of 115°C (90°C at size 250 to 1000) must not be exceeded locally either (e.g. in the bearing area). The temperature in the bearing area is - depending on pressure and speed - up to 12 K higher than the average case drain temperature.

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

For detailed information about use at low temperatures, see RE 90300-03-B.

Details regarding the choice of hydraulic fluid

The correct choice of hydraulic fluid requires knowledge of the operating temperature in relation to the ambient temperature: in a closed circuit the circuit temperature, in an open circuit the tank temperature.

The hydraulic fluid should be chosen so that the operating vis-cosity in the operating temperature range is within the optimum range (νopt.) - the shaded area of the selection diagram. We recommended that the higher viscosity class be selected in each case.

Example: At an ambient temperature of X°C an operating temperature of 60°C is set. In the optimum operating viscosity range (νopt; shaded area) this corresponds to the viscosity classes VG 46 or VG 68; to be selected: VG 68.

Please note: The case drain temperature, which is affected by pressure and speed, is always higher than the control temperature or tank temperature. At no point in the system may the temperature be higher than 115°C for sizes 5 to 200 or 90°C for sizes 250 to 1000.

If the above conditions cannot be maintained due to extreme operating parameters, we recommend flushing the case at port U (size 250 to 1000) or using a flush and boost pressure valve (see page 28).

FiltrationThe finer the filtration, the higher the cleanliness level of the hy-draulic fluid and the longer the service life of the axial piston unit.

To ensure functional reliability of the axial piston unit, the hy-draulic fluid must have a claenliness level of at least

20/18/15 according to ISO 4406.

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

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

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


Technical DataShaft seal ring

Permissible pressure loading

The service life of the shaft seal ring is affected by the speed of the motor 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 case drain pressure 6 bar absolute at reduced speed, see diagram). Short term (t < 0.1 s) pressure spikes of up to 10 bar absolute are permitted. The service life of the shaft seal ring decreases with an increase in the frequency of pressure spikes.

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

Flush and Boost Pressure ValveThe flush and boost pressure valve is used to remove heat from the closed control and to ensure that a minimum boost pressure is present (opening pressure 16 bar, fixed; note when setting primary valve). A side effect is flushing of the case.

Warm hydraulic fluid is directed from the respective low pres-sure side into the motor case. This is then fed into the tank, together with the case drain. The hydraulic fluid drawn out of the closed control in this way must be replaced by cooled hydraulic fluid that is supplied by the boost pump.

In an open control system, the flush and boost pressure valve is used solely to flush the case from the return line.

On port plate 027, the valve is fitted directly onto the fixed motor (size 45 to 180, 250), while on port plate 017 (size 355 and 500), it is fitted on a plate.

Orifices can be used to adjust the flushing volumes as required.

Pressure Relief ValvesThe pressure relief valves MHDB (as to RE 64642) protect the motor from excess pressure. When the set opening pressure is reached the hydraulic fluid flows from the high pressure side to the low pressure side.

The pressure relief valves can only be supplied in conjunction with the port plates 181, 191 or 192 (counterbalance valve for fitting on port plate 181, see next page).

Setting range opening pressure _______________50 – 420 bar

At design "with pressure sequence range" (192) a higher pressure setting can be realized by applying an external pilot pressure of 25 - 30 bar at port pSt.

Please indicate in clear text when ordering:

– opening pressure of the pressure relief valve

– opening pressure at pilot pressure applied at pSt (for design 192 only)

FunctionDriving/winch counterbalance valves are designed to redu-ce the danger of overspeeding and cavitation of axial piston motors in open controls. Cavitation occurs if the motor speed is greater than it should be for the given flow during braking, downhill travel or decrease in motor load.

Please note

– The BVD counterbalance valve must be specified explicitly in the order. We recommend ordering the counterbalance valve and the motor as a set. Ordering example: A2FM80/61W–VAB181 + BVD20F27S/41B–V03K16D0400S12

– The counterbalance valve does not replace the mechanical service brake and parking brake.

– Note the detailed information about the BVD counterbalance valve contained in RE 95522!

Attaching the counterbalance valveWhen delivered, the counterbalance valve is attached to the motor using 2 tacking screws. Do not remove the tacking screws when connecting the service lines. If the counterbalan-ce valve and motor are delivered separately, the counterbalan-ce valve must first be attached to the motor port plate using the provided tacking screws. In both cases, the final attachment of the counterbalance valve to the motor is by the connectio of the service lines, e.g. using SAE flanges. A total of 6 screws with thread lengths B1+B2+B3 and 2 screws with thread lengths B3+B4 are required.

When tightening the screws, it is imperative that the sequence (1 to 8) as shown in the adjacent diagram be adhered to and carried out in two phases.

In the first phase the screws should be tightened to 50% of their tightening torque before being tightened to maximum tightening torque in the second phase (see table below).

Speed MeasurementThe A2FM...D and A2FM...F ("prepared for speed measure-ment", i.e. without sensor) versions have teeth on the rotary group. The rotating, toothed rotary group generates a signal in proportion to the speed. The signal is picked up by a sensor and can be forwarded for evaluation.

The sensor is fitted to the special port D provided for this pur-pose. The following versions are available:

Version „D“ (sizes �3 to 180)

Suitable for mounting of inductive speed sensor ID (see RE 95130). The ID sensor is screwed into port D. The spacer ring required for the inductive speed sensor ID is included in the supply volume of the sensor (only when ordering, speed sensor with installation parts).

Version „F“ (sizes �3 to �50)

Suitable for mounting of HDD Hall effect speed sensor (see RE 95135). The HDD sensor is flange mounted with two faste-ning screws. In the standard version, the port is plugged with a pressure-resistant flange cover.

We recommend ordering the A2FM fixed motor complete with mounted sensor. Please specify the ordering code for the sensor separately.

Installation below the tank

Motor below min. fluid level in the tank (standard)

– Fill axial piston motor before startup via the highest case drain port

– Run the motor at low speed until the system is bled completely (bleed through service line port A, B if tubing is long)

– Minimum immersion depth of leakage line in tank: 200 mm (relative to the min. fluid level in the tank).

– Additional measures required for installation position 2 (shaft facing up): with installation position 2, make sure that the motor case is completely full before starting up. Bleed at port R (sizes 10 to 200) resp. U (sizes 250 to 1000). Order port R in clear text. An air pocket in the bearing area is leading to damage of the axial piston motor.

Installation NotesGeneral

The motor case must be completely filled up with hydraulic fluid during startup and during operation (filling the case chamber). The motor must be started up at low speed and no load until the system has been bled completely.

If stopped for an extended period, fluid may drain out of the case through the service lines. When restarting, make sure that the case contains sufficient fluid.

The leakage fluid inside the case chamber must be drained off to the tank through the highest case drain port.

Installation position

Optional. At size 10 to 200 with installation position “shaft to the top” use motor with bleeding port R (indicate in clear when orde-ring; the port U in the bearing section for bleeding is included in production with sizes 250 to 1000).

Installation above the tank

Motor above min. fluid level in tank

– Proceed in same way as below the tank installation

– Additional measures for installation positions 1 and 2: If stopped for an extended period, fluid may drain out of the case chamber through the service lines (air enters through the shaft seal). The bearings will therefore not be properly lubricated when the motor is started up again. Fill the axial piston motor before restarting via the highest case drain port. Installation position 2: bleed at port R (sizes 10 to 200) resp. U (sizes 250 to 1000). Order port R in clear text.

– Additional measures required for installation position 2 (shaft facing up): In this installation position the bearings will not be properly lubricated, even if there is still some fluid in the case cham-ber. Putting a non-return valve (opening pressure 0,5 bar) in the leakage line can prevent the system emptying through the line.
