EN Assembly instructions
1.4 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 modications or system repairs.
1.5 Compressed air hazard
The described product is pressurized
during operation. The product must
therefore be depressurized before
starting

or any system modications or system
repairs.
Depending on the model design, the product
may be able to be operated with compressed
air. Through the use of the appropriate com-
pressed air quality class, compressed air prep-
aration can be optimized and machine down-
time and higher maintenance costs avoided.
The compressed air to be used here must
comply with at least quality class 5 as dened
by ISO 8573-1:
1.6 Hydraulic pressure hazard
The described product is pressurized
during operation. The product must
therefore be depressurized before

Assembly instructions
1.7 Explosion protection information
Danger!
Only the pump models tested and
approved by SKF Lubrication Systems
Germany AG in accordance with ATEX
Directive 94/9/EC are permitted to be
used in areas with explosion protec-
tion. The relevant class of protection is
engraved on the pump's rating plate.
When lling lubricant into the pump,
make sure the lubricant is clean. The
reservoir
must be lled in good time (pay attention
to ll level monitoring). Lubricant must be
lled only via the ller socket G 3/8“ (FF)
or G 1/2“ (FB) on the pump ange. Lubri-
cant may only be lled via the "reservoir
lid" if absolutely certain that no potentially
explosive atmosphere exists.
In the case of overlling, the excessive
amount of lubricant must be removed.
Make sure there is no potentially explo-
sive atmosphere when doing this.
The switching circuits of the ll level
monitor
must be supplied by an intrinsically safe
circuit, e.g. through the installation of an
ATEX-compliant isolating switch by the
customer.
The unit must be grounded via a ground
connection. The customer must install
adequate overload protection for the
power consumption of the motor.
To avoid electrostatic discharge, lay
hydraulic connecting lines in corrosion-
resistant metal tubing, e.g. stainless steel
pipe.
When setting up the pump make sure the
setup location is even so that the unit will
not shudder.
During maintenance work, use only tools
intended for use in potentially explosive
spaces or else make certain that there is
no potentially explosive atmosphere
present.
The service life of the grease lubrication
pump is limited. It must therefore un-
dergo a function and leak test at regular
intervals. Perform appropriate repairs in
the event of malfunctions, leaks, or rust.
Replace the pump if necessary.
The user must make sure through the
choice of the lubricant to be delivered that
no chemical reactions capable of serving
as ignition sources will occur in conjunc-
tion with the explosive atmospheres
expected.
The lubricant’s ignition temperature has
to be at least 50 kelvins above the pump’s
maximum surface temperature (tempera-
ture class).

2. Lubricants
2.1 General information
All products from SKF Lubrication
Systems Germany AG may be used
only for their intended purpose and in
accordance with the information in the
product's assembly instructions.
Intended use is the use of the products for the
purpose of providing centralized lubrication/
lubrication of bearings and friction points us-
ing lubricants within the physical usage limits
which can be found in the documentation for
the devices, e.g. assembly instructions/operat-
ing 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 the same after consultation
with and written approval from SKF
Lubrication Systems Germany AG. No
products manufactured by SKF Lubrication
Systems Germany AG are approved for use in
conjunction with gases, liquefied gases, pres-
surized gases in solution, vapors, or such flu-
ids whose vapor pressure exceeds normal at-
mospheric 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 into the
products after consultation and written ap-
proval from SKF Lubrication Systems Germany
AG.
SKF Lubrication Systems Germany AG consid-
ers lubricants to be an element of system de-
sign which must always 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 these considerations.
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 specied by the
bearing or machine manufacturer. It
must be ensured 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.
Selection of a lubricant suitable for the lubri-
cation task is made by the machine/system
manufacturer and/or the operator of the ma-
chine/system in cooperation with the lubricant
supplier.
The bearings/friction points that require lubri-
cation, their expected load during operation,
and the expected ambient conditions are taken
into account during selection, with consider-
ation of economic and environmental aspects.

Page 11 EN
Assembly instructions
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.
SKF Lubrication Systems Germany AG
Systems Germany AG supports cus-
tomers
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 AG if you have further questions re-
garding lubricants. It is possible for lubricants
to be tested in the company's laboratory for
their suitability for pumping in centralized lu-
brication systems (e.g. "bleeding").
You can request an overview of the lubricant
tests offered by SKF Lubrication Systems
Germany AG from the company's Service
department.
2.3 Approved lubricants
Only lubricants approved for the prod-
uct may be used. Unsuitable lubricants
can lead to failure of the product and to
property damage.
Different lubricants cannot be mixed, as
mixing may result in damage and ne-
cessitate costly and complicated clean-
ing of the product/lubrication 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 product described here can be operated
using lubricants that meet the specifications in
the technical data. Depending on the product
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 added depending
on the operating conditions.
Note that in rare cases, there may be lubri-
cants whose properties are within permissible
limit values but whose other characteristics
render them unsuitable for use in centralized
lubrication systems. For example, synthetic lu-
bricants may be incompatible with elastomers.

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.
2.5 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. The
safety instructions on the lubricant's safety
data sheet must be followed. The safety data
sheet for a lubricant can be requested from
the lubricant manufacturer.

The FF and FB multiline pump units must be
installed on a level surface. The pump's base
plate must not be under stress. Sufficient
space must be provided during installation for
later service and maintenance work (see pages
13 and 15).
When the reservoir is empty and its lid is re-
moved, the agitator of the lubrication pump
should be visible, so that the functioning and
direction of rotation of the pump can be
checked by switching the pump on briey.
In the case of pumps with electrical grease-
or oil level monitoring, the clearance required
above the pump can be up to 400 mm, de-
pending on the height of the reservoir. The in-
stalled pump elements are set for full stroke,
with the ring pieces with the check valve (1)
pointing upwards. The cap nut (WAF 24) (2)
keeps the ring piece pressed against the screw
socket (3). If you want to point the ring piece
in a different direction, loosen the cap nut and
tighten it again with given Torgue, see Operat-
ing instructions, Fig. 8.4.1.
The number of pump elements can also be
changed later. The pump has to be shut done

4.3 Electrical motor connection
Connect the pump unit motor according to
the specications on the motor rating plate
and the motor characteristics.
Electric shock hazard
Electrical connections for the product
may only be established by qualied
and trained personnel authorized to do
so by the operator. The local conditions
for connections and local regulations
(e.g., DIN, VDE) must be observed.
Signicant bodily injury and property
damage may result from improperly
connected products.
Warning!
Connect lines in accordance with the
technical specications and the local
conditions for connections and local
regulations (e.g., DIN, VDE).
Consult the motor's rating plate for the elec-
trical characteristics of the motor, such as rat-
ed power, rated voltage, and rated current.
Observe the guidelines in EN 60034-1 (VDE
0530-1) for operation at the limits of the
ranges A (combination of ±5% voltage devia-
tion and ±2% frequency deviation) and B
(combination of ±10% voltage deviation and
+3/-5% frequency deviation). This applies es-
pecially with regard to heating and deviations
in operating parameters from the ratings on
the motor's rating plate. The limits must never
be exceeded.
The available mains voltage (supply
voltage) must be in accordance with the
specications on the rating plate of the
motor or of the electrical components.
Check the fuse protection of the electri-
cal circuit. Use only fuses with the
prescribed amperage, else bodily injury
and property damage may result.
Be sure to connect the motor so as to guaran-
tee a continuously safe electrical connection
(no protruding wire ends); use the assigned
cable end fittings (e.g. cable lugs, wire end
ferrules). Select connecting cables conforming
to DIN VDE 0100 taking into account the rated
current and the conditions of the specific sys-
tem (e.g. ambient temperature, type of routing
etc. in accordance with DIN VDE 0298 or IEC /
EN 60204-1). Details regarding electrical con-
nection of the motor to the power supply, es-
pecially terminal and connector pin assign-
ment, can be taken from the customer's
drawing for the reservoir unit.
Warning!
When establishing electrical connection
of the pump motor, be mindful of the
correct direction of rotation of the mo-
tor.
If the direction of rotation of a motor
is marked on the product by a rotation
arrow, the motor's direction of rotation
must match the arrow.
