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

The AA2FO fixed displacement pump is not suitable for use with HFA. If HFB, HFC and HFD or environmentally accep-table hydraulic fluids are being used, the limitation regarding technical data and seals mentioned in RE 90221 andRE 90223 must be observed. When ordering please indicate hydraulic fluid used.

Viscosity range

We recommend that a viscosity (at operating temperature) for optimum efficiency and service life purposes of

νopt = optimum viscosity 80...170 SUS (16...36 mm2/s)

selected, taken into consideration the tank temperature (open circuits).

Limits of viscosity range

The following values apply in extreme cases:

Sizes 5...200:νmin = 42 SUS (5 mm2/s)short term (t < 3 min) at max. permitted temperature of tmax = +240°F (+115°C).

νmax = 7400 SUS (1600 mm2/s), short term (t < 3 min) with cold start (p ≤ 435 psi / 30 bar,n ≤ 1000 rpm, tmin = -40°F / -40°C).

Sizes 250...1000: νmin = 60 SUS (10 mm2/s),short term (t < 3 min) at max. permitted temperature oftmax = +195°F (+90°C)

νmax = 4600 SUS (1000 mm2/s), short term (t < 3 min) with cold start (p ≤ 435 psi / 30 bar,n ≤ 1000 rpm, tmin = -13°F / -25°C).

Note that the maximum hydraulic fluid temperature must not be exceeded locally either (e.g. bearing area). The temperature in the bearing area is - depending on pressure and speed - up to 22 °F (12 K) higher than the average case drain temperature.

Special measures are necessary at temperatures between -40°F and -13°F (-40°C and -25°C). Please contact us.

See RE 90300-03-B for detailed information about operation at low temperatures.

Details regarding the choice of hydraulic fluid

To select the correct hydraulic fluid in open circuit applications, the temperature in the tank in relation to the ambient tempera-ture must be considered.

The hydraulic fluid should be selected so that within the operating temperature range, the operating viscosity lies within the optimum range (νopt) (see shaded section of the selection diagram). We recommend that the highest possible viscosity range should be selected in each case.

Example: At an ambient temperature of X°F (X°C) an opera-ting temperature of 140°F (60°C) is set in the circuit. 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 leakage fluid temperature, which is affected by pressure and rotational speed, is always higher than the cir-cuit temperature or tank temperature. At no point in the system may the temperature be higher than 240°F (115°C) for sizes 5 to 200 or 195°F (90°C) for sizes 250 to 1000.

If this cannot be achieved due to unusual operating parameters or high ambient temperatures, we recommend to apply bearing flushing at port U (sizes 250 ... 1000).

FiltrationThe finer the filtration, the cleaner the fluid, the longer the ser-vice life of the axial piston unit.

To ensure proper function of the axial piston unit, the Hydraulic 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), a cleanliness level of at least

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

Please contact us if these cleanliness leveles cannot be achieved.

With pulsating loads over pN = 4600 psi / 315 bar (pmax = 5100 psi / 350 bar);we recommend the use of a splined shaft (AA2FO 10...250: S, T or U / A2FO 200: A / A2FO 355...1000: Z)Attention: sizes 10 to 200: shaft end with drives of radial force loads at the drive shaft (pinion, V-belt drives) necessitate reduction of the nominal pressure to pN = 4600 psi (315 bar)! Sizes 250...1000 please contact us.

Minimum inlet pressure at suction port S with increased speed

In order to avoid damage of the pump a minimum inlet pressure at the suction port must be assured. The minimum inlet pressure is related to the rotational speed of the fixed pump.

Shaft seal ring

Permissible pressure load

The service life of the shaft seal ring is affected by the speed of the pump and the case drain pressure. The permitted loading with intermittent case drain pressure depends on the rotational speed (see chart). Short-term (t < 5 min) pressure spikes of up to 145 psi (10 bar) absolute are permitted.

The average permanent case drain pressure must not exceed 43.5 psi (3 bar) absolute.

The pressure in the case must be equal to or greater than the external pressure on the shaft seal.

Higher forces are permitted when under pressure. Please contact us.5) please contact us

When considering the permissible axial force, the force-transfer direction must be taken into account.

– Fax max = increase in service life of bearings

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 bearing. Recommended position of mating gear depending on direction of rotation. Examples:

Installation below the tankPumps below min. fluid level in the tank (standard)

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

– 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...200) resp. U (sizes 250...1000). An air pocket in the bearing area can cause damage to the pump.

– Recommendation: Fill up suction lines

– Run the pump at low speed until the system is bled completely

– Minimum immersion depth of leakage line in tank: 7.9 in (200 mm) (relative to the min. fluid level in the tank)

Installation and Commissioning NotesGeneralThe pump case must be completely filled with hydraulic fluid during startup and during operation (filling the case chamber). The pump must be started 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 12 psi (0.8 bar) absolute (see page 5).

Installation positionOptional.

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...200)resp. U (sizes 250...1000).

– 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 check valve (opening pressure 7.25 psi (0.5 bar)) in the leakage line can prevent the system emptying through the line.

– Note: min. admissible presssure at port S(min. suction pressure see page 5 and 8)

General Notes– The AA2FO pump is designed to be used in open circuits.

– Project planning, assembly, and startup of the pump require the involvement of trained personnel.

– The working and functional ports are only designed to accommodate hydraulic piping.

– Suction lines may need to be sized bigger than the suction port provided, depending on operation conditions, as required by good design practices. A smooth transition is to be provided in these installation conditions.

– Tightening torques

- The tightening torques specified in this data sheet are maximum values and may not be exceeded (maximum value for screw thread). Manufacturer specifications for the max. permissible tightening torques of the used fittings must be observed!

- For ISO 68 / DIN 13 fastening screws we recommend checking the tightening torque individually according to VDI 2230 Edition 2003.
