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.

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.

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.

Status 01/2001
For adaptations of operating viscosity to different operating and environment temperatures there are
hydraulic fluids of various viscosity classifications which normally lie between 22 and 68 mm2/s (in
reference to 40 °C temperature).
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).

Fluid Cleanliness Requirements
To achieve the specified unit life a cleanliness level as shown on the next page must be met.
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 step to the next cleanliness level means double or half the number of particles.
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:

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.

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

Due to the higher density compared to mineral oil the permissible suction pressure must be strictly
adhered to.
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

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.

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.
Further detailed notes are contained in Chapter 4.
