and GHS08 hazard pictograms
○to feed, forward, or store gases, liquefied
gases, dissolved gases, vapours, or fluids
whose vapour pressure exceeds normal
atmospheric pressure of 1013 mbar
[14.69 psi] by more than 0.5 bar [7.25
psi] at the maximum permissible operat-
ing temperature.

1.8 Notes related to the CE marking
CE marking is effected following the require-
ments of the applied directives:
○2014/30/EU
Electromagnetic compatibility
○2011/65/EU
(RoHS II) Directive on the restriction of
the use of certain hazardous substances
in electrical and electronic equipment
Reference on Low Voltage Directive
2014/35/EU
The protective regulations of Low Voltage
Directive 2014/35/EU are fulfilled accord-
ing to annex I (1.5.1) of Machinery Directive
2006/42/EC.
Reference on Pressure Equipment Directive
2014/68/EU
Because of its performance data the product
does not achieve the limit values defined in
Article 4 (1) (a) (i) and is therefore excluded
from the scope of application of Pressure
Equipment Directive 2014/68/EU following
Article 4 (3).
1.9 Inspections prior to delivery
The following inspections were carried out
prior to delivery:
○Safety and functional tests
○Electrical inspections following
ISO 60204-1
1.10 Other applicable documents
In addition to these instructions, the fol-
lowing documents must be observed by the
respective target group:
○Operational instructions and approval
rules
○Safety data sheet of the lubricant used
Where appropriate:
○Project planning documents
○Additional information on special ver-
sions of the pump. You will find these in
the special system documentation
○Any documents of other components
required to set up the centralized lubrica-
tion system

1.19 Initial commissioning / daily start-up
Ensure that:
○All safety devices are completely available
and functional
○All connections are correctly connected
○All parts are correctly installed
○All warning labels on the product are
present completely, highly visible and
undamaged
○Illegible or missing warning labels are to
be replaced without delay

2. Lubricants
2. Lubricants
2.1 General information
Lubricants are used specifically for cer-
tain application purposes. In order to fulfil
their tasks, lubricants must fulfil various
requirements.
The most important requirements for lubri-
cants are:
○Reduction of abrasion and wear
○Corrosion protection
○Noise minimisation
○protection against contamination or
penetration of foreign objects
○Cooling (primarily with oils)
○longevity (physical/ chemical stability)
○economic and ecological aspects
2.2 Selection of lubricants
SKF considers lubricants to be an element
of system design. A suitable lubricant is se-
lected already when designing the machine
and forms the basis for the planning of a
centralized lubrication system.
The selection is made by the manufacturer
or operator of the machine, preferably to-
gether with the lubricant supplier based on
the requirement profile defined.
Should you have little or no experience with
the selection of lubricants for centralized lu-
brication systems, please contact SKF.
If required we will be glad to support cus-
tomers to select suitable components for
feeding the selected lubricant and to plan
and design their centralized lubrication
system.
You will avoid possible downtimes through
damage to your machine or system or
damage to the centralized lubrication
system.
2.3 Material compatibility
Lubricants must generally be compatible
with the following materials:
○steel, grey iron, brass, copper, aluminium
○NBR, FPM, ABS, PA, PUR
2.4 Temperature characteristics
The lubricant used must be suitable for the
specific ambient temperature of the product.
The viscosity required for proper operation
of the product must be adhered to and must
not be exceeded in case of low temperatures
nor fall below specification in case of high
temperatures. Specified viscosities, see
chapter Technical data.

EN 2. Lubricants
w
Only lubricants specified for the
product (see chapter Technical
data) may be used. Unsuitable
lubricants may lead to a failure
of the product.
Do not mix lubricants. This may
have unforeseeable effects on
the usability and therefore on
the function of the centralized
lubrication system.
When handling lubricants the
relevant safety data sheets and
hazard designations, if any,
on the packaging have to be
observed.
2.5 Ageing of lubricants
After a prolonged downtime of the machine,
the lubricant must be inspected prior to
re-commissioning as to whether it is still
suitable for use due to chemical or physical
ageing. We recommend that you undertake
this inspection already after a machine
downtime of 1 week.
If doubts arise as to a further suitability of
the lubricant, please replace it prior to re-
commissioning and, if necessary, undertake
initial lubrication by hand.
It is possible for lubricants to be tested in the
company's laboratory for their suitability for
being pumped in centralized lubrication sys-
tems (e.g. "bleeding").
Please contact SKF. if you have further ques-
tions regarding lubricants.
You may request an overview of the lubri-
cants tested by SKF.
Due to the multitude of possible
additives, individual lubricants,
which according to the manu-
facturer's data sheets fulfil the
necessary specification, may not,
in fact, be suitable for use in cen-
tralized lubrication systems (e. g.
incompatibility between synthetic
lubricants and materials). In
order to avoid this, always use
lubricants tested by SKF.

2.6 Chisel pastes
NOTICE
Damage to the superior machine
Chisel pastes must not be used as a lubri-
cant for bearings.
NOTICE
Damage of the centralized lubrication
system
Chisel pastes may be supplied by pump
element C only. Hereby the maximum
operating pressure must not exceed 200
bar [2900 psi], as otherwise the solid lu-
bricants contained in the chisel paste may
cause increased wear.
2.6.1 Solid lubricants
w
Solid lubricants may be used only
upon prior consultation of SKF
Lubrications Systems.
With regard to the different solid lubricants
contained in chisel pastes, please observe
the following:
Graphite
max. graphite content 8 %
max. particle size 25 µm
(possibly in in lamellar structure)
MoS2
max. MoS2content 5 %
max. particle size 15 µm
Copper
Chisel pastes containing copper are likely to
result in a layer formation on pistons, bores
and mating surfaces. This may cause block-
ages in the centralized lubrication system.
Calcium carbonate
Chisel pastes containing calcium carbonate
are likely to cause a very strong wear on pis-
tons, bores and mating surfaces.
Calcium hydroxide
Chisel pastes containing calcium hydroxide
are likely to harden strongly, what may result
in a downtime of the centralized lubrication
system.
PTFE, zinc and aluminium
Due to the findings and practical experiences
gained so far, no limit values can be set for
these solid lubricants yet.

3.1 Pumps without follower plate
1 Reservoir
The lubricant is stored in the reservoir. De-
pending on the pump version there are differ-
ent types of reservoirs and reservoir sizes.
1.1 Reservoir lid
Serves as a protection against contamination
of the lubricant. After removing the reservoir
lid the reservoir can be filled from the top with
suitable clean lubricant.
1.2 Reservoir venting device
It provides air for the reservoir while the pump
is operating and lubricant is supplied.
10 Stirring paddle
While the pump operates, the stirring paddle
homogenises and smoothens the lubricant.
The stirring paddle's lower vertical part pushes
the lubricant towards the pump elements thus
improving the suction behaviour of the pump.
