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 pump A2FO 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 tank 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 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 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).
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 cleanliness 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.

Shaft seal ring
Permissible pressure loading for shaft seal ring FKM
The service life of the shaft seal ring is affected by the speed of the 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 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.

a specific mass of 0,88 kg/L).2) By increase of the input pressure (pabs > 1 bar) the rotational speeds can be increased to the max. admissible speeds nmax limit
(speed limits) (see diagram page 4).3) Torque at Δp = 315 bar
Caution: Exceeding the permissible limit values may result in a loss of function, a reduction in service life or in the destruction of the axial piston unit. Other permissible limit values with respect to speed variation, reduced angular accelaration as a function of the frequency and the permissible startup angular acceleration (lower than the maximum angular acceleration) can be found in data sheet RE 90261.

When considering the permissible axial force, the force-transfer direction must be taken into account:
– Fax max = increase in service life of bearings
+ Fax max = reduction in service life of bearings (avoid)
Effect of radial force Fq on the service life of the bearings
By selecting a suitable force-transfer direction of Fq, the stress on the bearing caused by the internal transmission forces can be reduced, thus achieving the optimum service life for the bearings. Recommended position of mating gear is dependent on direction of rotation. Examples:

Installation below the tank
Pump below min. fluid level in the tank (standard)
– Fill axial piston pump before startup via the highest case drain port
– Run the pump at low speed until the system is bled completely.
– 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 pump case is completely full before starting up. Bleed at port R (sizes 10 to 200) resp. U (sizes 250 to 1000). An air pocket in the bearing area is leading to damage of the axial piston pump.
– Recommendation: Fill up suction lines

Installation notesGeneral
The pump case must be completely filled up with hydraulic fluid during startup and during operation (filling the case chamber). The pump 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. The min. suction pressure at port S must not fall below 0,8 bar absolute (see page 4).
Installation position
Optional.
Installation above the tank
Pump above minimum 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 pump is started up again. Fill the axial piston pump 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).
– 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.
– Note: min. admissible pressure at port S (min. suction pres-sure see page 5)

General Notes– The A2FO pump is designed to be used in open circuits.
– Project planning, assembly, and commissioning of the pump require the involvement of qualified personnel.
– The service line ports and function ports are only designed to accommodate hydraulic lines.
– During and shortly after operation, there is a risk of burns on the pump. Take suitable safety precautions, e.g. wear protective clothing
– There may be shifts in the characteristic depending on the operating state of the pump (operating pressure, fluid temperature).
– Tightening torques: - The tightening torques specified in this data sheet are maximum values and must not be exceeded (maximum values for screw thread). Manufacturer's instruction for the max. permissible tightening torques of the used fittings must be observed! - For DIN 13 fixing screws, we recommend checking the tightening torque individually according to VDI 2230 Edition 2003.
– The data and information contained herein must be adhered to.
