1. Safety instructions
In addition to the manual,
statutory regulations and other general
regulations for accident prevention
and environmental protection must be
observed and applied.
1.2 Authorized personnel
Only qualified technical personnel may install,
operate, maintain, and repair the component
described in this manual. Qualified technical
personnel are persons who have been trained,
assigned and instructed by the operator of the
final product into which the described compo-
nent is incorporated. Such persons are familiar
with the relevant standards, rules, accident
prevention regulations, and assembly condi-
tions as a result of their training, experience,
and instruction. They are authorized to identify
and perform necessary actions while avoiding
any risks which may arise.
The definition of qualified personnel and the
prohibition against employing non-qualified
personnel are laid down in DIN VDE 0105 and
IEC 364.
The described component is manufactured in
accordance with the generally accepted rules
and standards of industry practice and with
occupational safety and accident prevention
regulations. Risks may, however, arise from
its usage and may result in physical harm to
persons or damage to other material assets.
Therefore the component may only be used in
proper technical condition and in observance
of the “component lifecycle manual.” In partic-
ular, any malfunctions which may affect safety
must be remedied immediately.
1.1 Intended use
The SKF MonoFlex prelubrication distributor
of product series VR is designed for positively
driven distribution of lubricants (greases and
fluid greases up to NLGI grade 2) in a single-
line centralized lubrication system. The maxi-
mum permissible operating pressure of the VR
distributor is 315 bar. The relief pressure can be
chosen as either 30 or 70 bar. The inlet and
outlet screw unions and their connecting lines
must be designed for these parameters.
The temperature range of the VR prelubrication
distributor is - 25°C to +80°C. The lubricant
used must be suitable for elastomers (FKM/
FPM).
The technical requirements for the installation
of the VR prelubrication distributor are set out
in chapter 4, “Assembly.” These requirements
must be complied with. The same applies to the
technical specifications for the VR prelubrication
distributor in chapter 10, “Technical data.”
Any other or additional usage of the VR prelu-
brication distributor is deemed non-compliant
with the intended use.

1.3 System pressure hazard
Lubrication systems are pressurized
during operation. Centralized lubri-
cation systems must therefore be
depressurized before starting assembly,
maintenance or repair work, or any
system modifications or system repairs.

2. Lubricants
2.1 General information
All components from SKF Lubrication
Systems Germany GmbH may be used
only for their intended purpose and in
accordance with the information in this
manual.
Intended use is the use of the components
for the purpose of providing centralized lu-
brication/lubrication of bearings and friction
points or volumetric flow control in hydraulic
systems, within the physical usage limits which
can be found in the documentation for the
device, e.g. assembly instructions/operating
instructions and the product descriptions, e.g.
technical drawings and catalogs.
Particular attention is called to the fact that
hazardous materials of any kind, especially
the materials classified as hazardous by EC
Directive 67/548/EEC, Article 2, Para. 2, may
only be filled into SKF centralized lubrication
systems and components and delivered and/or
distributed with such systems and components
after consulting with and obtaining written ap-
proval from SKF Lubrication Systems Germany
GmbH. No components manufactured by
SKF Lubrication Systems Germany GmbH are
approved for use in conjunction with gases,
liquefied gases, pressurized gases in solution,
vapors, or such fluids whose vapor pressure
exceeds normal atmospheric pressure (1013
mbar) by more than 0.5 bar at their maximum
permissible temperature.
Other media which are neither lubricant nor
hazardous substance may only be fed after
consultation with and written approval from
SKF Lubrication Systems Germany GmbH.
SKF Lubrication Systems Germany GmbH
considers lubricants to be a component of the
system design and must be factored into the
selection of components and the design of
centralized lubrication systems. The lubricating
properties of the lubricants are critically im-
portant in making these selections.
2.2 Selection of lubricants
Observe the instructions from the
machine manufacturer regarding the
lubricants that are to be used.
Warning!
The amount of lubricant required at
a lubrication point is specified by the
bearing or machine manufacturer. It
must be ensured that that the required
quantity of lubricant is provided to the
lubrication point. The lubrication point
may otherwise not receive adequate
lubrication, which can lead to damage
and failure of the bearing.
The selection of a lubricant suitable for the lu-
brication task is made by the machine/system
manufacturer and/or the operator of the ma-
chine/system in cooperation with the lubricant
supplier.
When selecting a lubricant, the type of bear-
ing/friction point, their expected load during
operation, and the anticipated ambient condi-
tions must be taken into account. All economic
and environmental aspects must also be
considered.

2. Lubricants
SKF Lubrication Systems Germany
GmbH supports customers
in the selection of suitable components
for feeding the selected lubricant and in
the planning and design of a
centralized lubrication system.
Please contact SKF Lubrication Systems
Germany GmbH if you have further questions
regarding lubricants. Lubricants can be tested
in the company's laboratory for their suitability
for pumping (e.g. bleeding characteristics) and
for use in centralized lubrication systems.
You can request an overview of the lubricant
tests offered by SKF Lubrication Systems
Germany GmbH from the company's Service
department.
2.3 Approved lubricants
Only lubricants approved for the
component may be used. Unsuitable
lubricants can lead to failure of the
components and damage to property.
Different lubricants must not be mixed,
as mixing may result in damage and
necessitate costly and complicated
cleaning of the components/lubrica-
tion system. It is recommended that
an indication of the lubricant in use be
attached to the lubricant reservoir in
order to prevent accidental mixing of
lubricants.
The described components can be operated
using lubricants that meet the specifications in
the technical data. Depending on the compo-
nent design, these lubricants may be oils, fluid
greases, or greases.
Oils and base oils may be mineral, synthetic
and/or rapidly biodegradable.
Consistency agents and additives may be add-
ed depending on the operating conditions.
Note that in rare cases, there may be lubricants
whose properties are within the permissible
limits values but whose other characteristics
render them unsuitable for use in centralized
lubrication systems. For example, synthetic lu-
bricants may be incompatible with elastomers.

2.4 Lubricants and the environment
Lubricants can contaminate soil and
bodies of water. Lubricants must be
properly used and disposed of. Observe
the local regulations and laws regarding
the disposal of lubricants.
It is important to note that lubricants are envi-
ronmentally hazardous, flammable substances
which require special precautionary measures
during transport, storage, and processing.
Consult the safety data sheet from the lubri-
cant manufacturer for information regarding
transport, storage, processing, and environ-
mental hazards of the lubricant that will be
used.
The safety data sheet for a lubricant can be
requested from the lubricant manufacturer.
2. Lubricants/ 3. Transport, delivery, and storage
2.5 Lubricant hazards
Centralized lubrication systems must
always be free of leaks. Leaking lu-
bricant is hazardous due to the risk of
slipping and injury. Be mindful of any
lubricant leaking out during assembly,
operation, maintenance, and repair of
centralized lubrication systems. Leaks
must be sealed off without delay.
Lubricant leaking from centralized lubrication
systems is a serious hazard. Leaking lubricant
can create risks that may result in physical
harm to persons or damage to other material
assets.
Follow the safety instructions on the
lubricant's safety data sheet.
Lubricants are a hazardous substance. Follow
the safety instructions on the lubricant's safety
data sheet. The safety data sheet for a lu-
bricant can be requested from the lubricant
manufacturer.
