Status 01/2001 Introduction The performance requirements of machine elements and also hydraulic fluids have increased on an ongoing basis. However, let us not forget that pressure media are limited by their inherent natural characteristics; this applies in particular to mineral oil based hydraulic fluids. The dependency on crude oil markets, the general availability and the environmental hazard potential have increasingly become a deciding factor. The more important ecological considerations, however, were the reason why the search for new basic fluids, which cannot always meet all requirements of the present standards, has been intensified and will continue to be pursued well into the future. This search for new basic fluids has caused the mineral oil industry to take two routes so that today two different environmentally compatible hydraulic fluids are available on the market. In principle today’s products are differentiated as synthetic and natural products. It is this differentiation, however, that frequently leads the user to ask for the „right“ solution to his problem. It is the goal of this technical application information to enable the machine operator to choose suitable hydraulic fluids. 3 BACK Applications Technical Information • ATI-9101-E 2. Status 01/2001 Hydraulic Fluids for Hydraulic Machinery Hydraulic fluids have the primary purpose of transferring potential or kinetic energy (pressure and movements), create volume flow between pump and hydrostatic motor, and reduce the wear of parts that rub against each other. In addition, they are to protect the system from corrosion and help carry away the heat produced during energy transformation. 2.1 General Requirements for Hydraulic Fluids Illustration 1 will give an outline of the necessary requirements for hydraulic fluids required: prerequisites: 1. Volume stability: adequate capacity to separate air 2. Wear protection capacity: for a hydrodynamic or hydrostatic fluid layer between sliding surfaces: adequate viscosity at operating temperature; for all others: wearreducing active components 3. Corrosion Protection Capacity non-aggressive toward customary materials, rust protection additive desirable: 4. Only slight change in usage: 5. Viscosity-Temperature Behavior: 6. Interaction with Seals/Gaskets adequate oxidation resistance for some cases of application; adequate de-emulsification capacity; in case of fluids with viscosity index: adequate shear stability in such a way that oil changes due to temperature changes in the environment become redundant; adequately low V/T dependency such that standard sealing materials can be used; slight changes in the characteristics of standard elastomers Illustration 1: Necessary Characteristics of Hydraulic Fluid For most of the identifying characteristics listed in Illustration 1, there already exists standards or at least preferred testing procedures which allow a numerical classification of these identifying features. 4 BACK Applications Technical Information • ATI-9101-E 2.2 Status 01/2001 Hydraulic Fluids for Sauer-Danfoss Hydrostatic Transmissions The general requirements for hydraulic fluids already addressed in 2.1 are also listed for Biodegradable Hydraulic Fluids in the German Standard VDMA 24568 - Rapidly Biologically Degradable Hydraulic Fluids Minimum Technical Requirements The VDMA 24568 is a preliminary guideline. Serveral technical data have to be evaluated and specified for the use in hydrostatic transmissions by the standardization group. Therefore todays hydraulic fluids following VDMA 24568 do not operate satisfactory under all circumstanses. The requirements for proven mineral based hydraulic fluids are specified in DIN 51524 Part 2 - Hydraulic Oils HLP DIN 51524 Part 3 - Hydraulic Oils HVLP For flawless operation within the rated specifications of hydrostatic components Sauer-Danfoss requires that the hydraulic fluid fulfill the minimum requirements of: DIN 51524 In the development of new pressure liquids there is always the danger of unexpected interchange effects of the components used. Therefore, despite adherence to these minimum requirements additional tests, specifically developed for fluids, may be necessary. In addition, the adherence to minimum requirements does not mean that the pressure fluid may be used without restrictions. Besides hydraulic oils according to DIN 51524, hydraulic fluids according to other specifications have been released for operation (see also Sauer-Danfoss hydraulic fluids and lubricantion, ordernumber 697 581 or consult with the central Applications Department). 2.2.1 Operating Data for Sauer-Danfoss Hydrostatic and Mechanical Transmissions In order to guarantee a trouble-free and economical operation of the machinery the pressure fluid must be carefully selected in accordance with the optimum operating data of the machinery components during the layout phase already. In addition to the density and pour point, the viscosity/temperature behavior is of primary importance. In order to avoid increased wear due to increasing boundary lubrication conditions, the viscosity should not fall below a minimum limit under any operating conditions. Illustration 2 shows the recommended viscosity limits with reference to the different transmission components. 5 BACK Applications Technical Information • ATI-9101-E Status 01/2001 Figure 2: Guidelines for hydraulic fluid selection with respect to the hydraulic system Mindestviskosität (kurzzeitig) min.

The viscosity index (VI) is a measurement for the slope of the straight line in the viscosity/temperature diagram (see Illustration 3). Standard HLP hydraulic oils have a VI of app. 100. Most presently available „biodegradable“ hydraulic fluids have a VI in the range of approx. 200. This high viscosity index gives these fluids and the HVLP oils multiple range characteristics and they are, therefore, well adapted for mobile use (changing temperatures). 7 BACK Applications Technical Information • ATI-9101-E Status 01/2001 Illustration 3: Viscosity-Temperature Diagram of Hydraulic Fluids 2000000 -40 -30 -20 -10 0 10 20 30 40 50 60 70 80 90 100 110 120 130 140 150 500000 300000 200000 100000 70000 50000 30000 20000 ISO VG 100 (VI = 98) ISO VG 68 (VI = 100) ISO VG 46 (VI = 103) ISO VG 32 (VI = 107) ISO VG 22 (VI = 105) 10000 7000 5000 4000 3000 νmax kurzzeitig bei Kaltstart 50 40 30 25 20 18 16 100 mm 2/s 90 80 70 60 50 Alle Baureihen ● All Series 100 90 80 70 60 Baureihe ● Series 15 150 Baureihe ● Series 10,20 200 Baureihe ● Series 40, 42, 51, 90, CW5-8* 300 intermittentcold start ISO VG 32 (VI = 200) Umweltschonende Druckflüssigkeit • Biodegradable Hydraulic Fluid Baureihe ● Series 45 1000 800 700 600 500 400 Baureihe ● Series 60,LPM* 2000 1500 Zahnradpumpen u.

Fluid samples shall be taken either in the loop or the entry in the pump which is typically the suction line. This depends on the continuous system pressure (Curve A) and new fluid and start up conditions (Curve C & D). The following requirements reflect the experience gained from a broad range of applications. For very high lifetime requirements or contamination sensitive components (e.g. servo valves better cleanliness levels are necessary). A Cleanliness level 18/13 per ISO 4406 for continuous pressure2 to 240 bar C Min. cleanliness at: - New machine shipment Fluid change or addition D Minimum cleanliness at first machine start up.Exceeding this level will result in start-up damage. Curves A is related to a continuous pressure. Because the pressure fluctuates in a power pack or vehicle this often can not be measured. It is usual to use an average pressure level upon a duty cycle for the machine or funktion. If this is not clear, please contact your local SAUER-DANFOSS representative. 2 Continuous pressure as defined in DIN 24 314 A machine can be operated with the continuous pressure during the desired lifetime.

The required cleanliness class definition is determined by ISO 4406 - Dec. 1999. The old version is from 1987. The related particle sizes are as follows in the new ISO 4406: Old New ISO 4406-1987 ISO 4406-1999 not defined 4 µm (c) 5 µm 6 µm (c) 15 µm 14 µm (c) please note, that “(c)” must be added to the new definition in order to identify that it is the new ISO 4406. The old method for particle counting may still be used. Measurements of one fluid sample will result in the same cleanliness class for both methods. The requirement 22/18/13 means: 22 specifies the number of particles larger than 4 (c) µm, 18 specifies the number of particles larger than 6 (c) µm and 13 the number of particles larger than 15 (c) µm related to 100 ml of the inspected fluid. 11 BACK Applications Technical Information • ATI-9101-E Status 01/2001 Together with this ISO 4406 change a new calibration standard ISO 11 171 - 1999 and a new Multipass test for filters have been developed.

Please note that despite fulfillment of the technical requirements of DIN 51524 this fluid cannot be used without reservations (see 2.2). 14 BACK Applications Technical Information • ATI-9101-E Status 01/2001 Operating Data For the use of Sauer-Danfoss hydrostatic transmissions the same application limits and operating data apply as for the operation with HLP hydraulic oils. Under consideration of the HETG fluid the temperature range, however, is limited to -15 °C to 70 °C In order to avoid accelerated aging of the fluid , tank temperatures of over 60 °C should be avoided. All transmission components are tested with mineral oil. All housings should be drained completely before installation. Fluid Change Intervals: Sauer-Danfoss recommends the following for fluid changes: First change 500 operating hours after start up. Second and subsequent changes after 1000 operating hours or once a year. This recommendation applies for the most applications. High temperatures and pressures will result in accelerated fluid aging and an earlier fluid change may be required. At lower fluid loads longer change intervals are possible. Therefore we suggest to check the fluid with the manufacturer for suitability. This should be done latest half way between fluid changes. Hints for the transition period VDMA Harmonisation Sheet 24569 „Rapidly Biologically Degradable Hydraulic Fluids“ and the appropriate guidelines of each individual hydraulic fluid manufacturer are applicable. The remaining max residual volume as specified in VDMA 24569 must not be exceeded. 15 BACK Applications Technical Information • ATI-9101-E 4.2 Status 01/2001 Polyglycol based Hydraulic Fluids - HEPG Fluid Characteristics: - very good viscosity/temperature behavior - biologically degradable - water hazard class WGK 0 - good corrosion protection - partially unacceptable compatibility with seals/gaskets - density > 1.0 g/ml - pour point app. -10 to -25 °C. - the minimum requirements of VDMA 24568 are generally met - the minimum requirements of DIN 51524, part 2 and 3 are fulfilled Please note that despite fulfillment of the technical requirements of DIN 51524 this fluid cannot be used without reservations (see 2.2). Operating Data For the use of Sauer-Danfoss hydrostatic transmissions the same application limits and operating data apply as for the operation with HLP hydraulic oils. Due to the higher density compared to mineral oil the permissible suction pressure must be strictly adhered to. All transmission components are tested with mineral oil. All housings should be drained completely before installation. Fluid Change Intervals: Sauer-Danfoss recommends the following for fluid changes: First change 500 operating hours after start up. Second and subsequent changes after 2000 operating hours or once a year. This recommendation applies for the most applications. High temperatures and pressures will result in accelerated fluid aging and an earlier fluid change may be required. At lower fluid loads longer change intervals are possible. Therefore we suggest to check the fluid with the manufacturer for suitability. This should be done latest half way between fluid changes. Hints for the Transition Based on a few particular characteristics of polyglycol based fluids, as for example, - partially unacceptable paint incompatibility - low seal/gasket compatibility - no mixability with mineral oil the exchange of fluids in existing installation may be very expensive. Particular attention must receive the VDMA Harmonisation Sheet 24569 „Rapidly Biologically Degradable Hydraulic Fluids“ and the individual oil manufacturer must receive particular attention - it is these guidelines that apply. The remaining max residual volume as specified in VDMA 24569 must not be exceeded. 16 BACK Applications Technical Information • ATI-9101-E 4.3 Status 01/2001 Synthetic Ester Hydraulic Fluids - HEES Fluid Characteristics: - very good viscosity/temperature behavior - biologically well degradable - water hazard class WGK 0 - good corrosion protection - good compatibility with seals/gaskets - good lubricating characteristics - good aging resistance - density app. 0.92 g/ml - pour point app. -10 to -25 °C - the minimum requirements of VDMA 24568 are generally met - the minimum requirements of DIN 51524, part 2 and 3 are fulfilled Please note that despite fulfillment of the technical requirements of DIN 51524 this fluid cannot be used without reservations (see 2.2).

Status 01/2001 Application Table Hydraulic Fluids/Gear Units For the previously described kinds of biodegradable hydraulic fluids Sauer-Danfoss has more or less wellfounded experience available. This evidence on the use of fluids is the basis for possible releases. None of the fluids in general has been approved for Sauer-Danfoss products. Our warranty conditions - which refer to defects that we are responsible for - also apply to the use of environmentally friendly fluids, however, fluid related damages are excluded. Illustration 7 shows the experiences for the various design series and the various kinds of fluids available. This available knowledge is divided into the following criteria: ➀ hydraulic fluid has already been used successfully ➁ no or little experience ➂ avoid use Fluids that have been applied extensively already may be found by consulting the footnotes (in the application table) in the table referring to Illustration 7. In the future we hope to be able to approve more fluids due to extensive testing experience and increasing cooperation by mineral oil companies in optimizing hydraulic fluids. 18 BACK Applications Technical Information • ATI-9101-E Name of unit or series Status 01/2001 Rape seed based hydraulic fluid Polyglycol based hydraulic fluid Synthetic ester based hydraulic fluid HETG HEPG HEES Series 10 ➁ 2), 3) ➁ ➁ 24) Series 10 Open Circuit ➁ 2), 3) ➁ ➀ 1)24) RMF-Wheel Motors (hydraulic motor only) ➀ 2), 3) ➁ ➀ 24) Series 20 ➀ 15), 20) Series 40 ➀ 2), 3) Series 42 ➀* 4)-9) ➀ 10)-12) 19)24)-25) ➁ ➁ 24) ➁ ➁ ➁ 24) Series 45 ➁ ➁ ➁ 24) Series 50 ➁ ➁ ➀ 10)-12)24) 10)-12) 23)-24) 21)-22) 15), 20) ➁ 15), 20) ➁ ➀ ➁ Series 60 ➁ 1) ➁ ➁ Series 90 ➀ 14)-18), 20) ➀ 4)-9) ➀ ➁ SP Gear Pumps ➁ ➁ 4)-9) ➀ 10)-12)24)26)27)28) SNP Gear Pumps + Gear Motors ➁* ➁ ➁ ➁ ➁ ➁ Series 51 10)-12) 23)-24) 21)-22) Mechanical Gears • Splitter box • Planetary gears Illustration 7: Fluid Experience table ➀ Fluid has been used succesfully ➁ No or only a little experience ➂ Avoid useage * Special configuration required 1), 2), ... 26) see page 19 19 BACK Applications Technical Information • ATI-9101-E Status 01/2001 List of the individual fluids for which extensive test experience is available including applicable footnotes from Illustration 7 1) 2) 3) 4) 5) 6) 8) 9) 10) 11) 12) 14) 15) 16) 17) 18) 19) 20) 21) 22) 23) 24) 25) 26) 27) 28) 20 ELF - Hydrelf Bio 46 SHELL - Naturelle HFR 32 BP - Biohyd 32/46 FRAGOL - Hydraulic TR 22/32/46 AVIA - Hydrosynth 22/32/46 SHELL - Fluid BD 22/32/36 WINTERSHALL - Wiolan HU 32/46 BP-Biohyd PEG 22/46 PANOLIN - HLP Synth 15/22/32/68 ASEOL - Terra 16-783 46 und Terra 16-784 68 SHELL - Naturelle HFE 15/46/68 NUHN - RT HVI 32 FUCHS - Plantohyd N 46 RAISIO - Bio safe 32/68 CASTROL - Biotec HVX 32 ESSO - Hydrauliköl PFL ÖMV - Biohyd MS 46 Bucher AG/Motorex & Cie GmbH - Oekohydro 3268 SUOMEN PETROOLI OY - Teboil Hydraulic Eco 46 DEA - Econa E 46 RAISIO - Bio Safe 46 SE Fuchs - Plantosyn 46 HVI Mobil - Hydraulic UF 46 Mobil - EAL Syndraulic 46 and EAL Envirosyn H 46 FINA - Biohydran SE 46 Texaco - Hydra 46 BACK Applications Technical Information • ATI-9101-E 6. Status 01/2001 Suggestions for Disposal Much like hydraulic fluids on a mineral oil basis, all „biodegradable“ hydraulic fluids are subject to special disposal regulations. The legal ordinances and regulations of the individual states in Germany and other countries will apply. Particularly the instructions of the fluid manufacturer must be followed. Note: Many manufacturers voluntarily offer to take back the used fluids. 7. Suggestions for the User Since only insufficient long term experience is available as of now on the application of biodegradable hydraulic fluids, Sauer-Danfoss cannot guarantee flawless operation of these fluids for every application. For high performance installations we recommend thorough field testing of the fluid in questions. Basic Presumptions: Before changing a machine over to a new oil it is imperative to consult with the individual manufacturer of each machine. To avoid damage caused by the hydraulic fluid we recommenend to take fluid samples every 150 - 200 operating hours. The fluid manufacturer should check the further fluid useability. Manufacturers who would like to use biodegradable hydraulic fluids in Sauer-Danfoss hydrostatic transmissions should refer to our central Applications Department if the fluid in questions has not yet been released.
