Hydraulic fluid

Before starting project planning, please refer to our datasheets RE 90220 (mineral oil), RE 90221 (environmentallyacceptable hydraulic fluids) and RE 90223 (HF hydraulicfluids) for detailed information regarding the choice of hydraulic

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

Viscosity range

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

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

selected, taken into consideration the tank temperature (opencircuits).

Limits of viscosity range

The following values apply in extreme cases:

Sizes 5...200:

min = 42 SUS (5 mm2/s)short term (t < 3 min) at max. permitted temperature oftmax = +240F (+115C).

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

Sizes 250...1000:

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

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

Note that the maximum hydraulic fluid temperature must not beexceeded locally either (e.g. bearing area). The temperature inthe bearing area is - depending on pressure and speed - up to22 F (12 K) higher than the average case drain temperature.

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

See RE 90300-03-B for detailed information about operationat 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 theoperating temperature range, the operating viscosity lies withinthe optimum range (opt) (see shaded section of the selectiondiagram). We recommend that the highest possible viscosityrange should be selected in each case.

Example: At an ambient temperature of XF (XC) an opera-ting temperature of 140F (60C) is set in the circuit. In the

optimum operating viscosity range (opt; shaded area) thiscorresponds to the viscosity classes VG 46 or VG 68; to beselected: VG 68.

Please note: The leakage fluid temperature, which is affectedby pressure and rotational speed, is always higher than the cir-cuit temperature or tank temperature. At no point in the systemmay the temperature be higher than 240F (115C) for sizes 5to 200 or 195F (90C) for sizes 250 to 1000.

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

Filtration

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

To ensure proper function of the ax ial piston unit, the Hydraulicfluid must have a cleanliness level of at least

20/18/15 according to ISO 4406.

At very high hydraulic fluid temperatures (90C to max. 115C, notpermitted 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 reductionof 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 pressureis 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 ofthe pump and the case drain pressure. The permitted loading

with intermittent case drain pressure depends on the rotationalspeed (see chart). Short-term (t < 5 min) pressure spikes of upto 145 psi (10 bar) absolute are permitted.

The average permanent case drain pressure must not exceed43.5 psi (3 bar) absolute.

The pressure in the case must be equal to or greater than theexternal 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

+ Fax max = reduction in service life of bearings (avoid if at all possible)

Effect of radial force Fq on the service life of the bearings

By selecting a suitable force-transfer direction of Fq, the stresson the bearing caused by the internal transmission forces canbe reduced, thus achieving the optimum service life for thebearing. Recommended position of mating gear depending ondirection of rotation. Examples:

Installation below the tank

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

Fill axial piston pump before startup via the highestcase drain port

Additional measures required for installation position 2

(shaft facing up): with installation position 2, make sure thatthe pump case is completely full before starting up. Bleedat port R (sizes 10...200) resp. U (sizes 250...1000). An airpocket 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 bledcompletely

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 NotesGeneral

The pump case must be completely filled with hydraulic fluid during startup and during operation (filling the case chamber). Thepump 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 thecase 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. suctionpressure at port S must not fall below 12 psi (0.8 bar) absolute (see page 5).

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 throughthe shaft seal). The bearings will therefore not be properlylubricated when the pump is started up again. Fill the axialpiston 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 properlylubricated, even if there is still some fluid in the case cham-ber. Putting a check valve (opening pressure 7.25 psi (0.5bar)) in the leakage line can prevent the system emptyingthrough 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 fitt ingsmust be observed!

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

The housing temperature rises during and shortly after operation. Take suitable safety precautions (e.g. wear protective clothing).

The data and information contained herein must be adhered to.
