o Protecting against dirt or foreign matter
o Extending t e service life of bearings, c ains, etc.
o Cooling

10 BIJUR DELIMON INTERNATIONAL BA_2020_1_GB_FAX_FBX
2.10.1 Selecting lubricants
Lubricants are usually selected during machines’ and systems’ design phase. They are selected by the machine manufacturer or, if
appropriate, the machine operating company. The product’s operating temperature or the ambient temperature must also be
taken into account. DELIMON takes the lubricant specification into account during the project planning process and when selecting
suitable central lubrication components. If it does not have any relevant experience with regard to the compatibility of given
lubricants, Bijur Delimon also offers preliminary tests to assess the compatibility.
Material compatibility:
The used lubricants must generally be compatible with the following materials and seals:
Steel, grey cast iron, brass, copper, aluminium
NBR, FPM, FKM, ABS, PA, PU
Only lubricants specified for the product (see the section entitled ‘Technical data’) may be used. All other system
components’ specified lubricants must also be observed! Unsuitable lubricants can lead to functional failure of the
product or the entire system.
Do not mix lubricants. This has an impact on the lubricating properties and feedability, and thus on the central
lubrication system’s function.
It must be ensured that flammable media inside the pump are not heated above 80 % of their ignition temperature
without the application of special measures.
When handling lubricants, the relevant safety data sheets and, if applicable, the hazard labels on the packaging
must be observed
2.10.2 Lubricant ageing
If lubricants are stored in reservoirs or lines for an extended period of time, e.g. due to machine downtime, ageing phenomena may
occur (e.g. separated lubricant components). Before putting the machine / system back into operation, check whether the
lubricant is still suitable for use. If necessary, the lubricant must be replaced before the machine / system is put back into
operation.
2.11 Foreseeable misuse
Misuse is considered to be unintended use, especially in the following cases:
oOperation outside the specified operating temperature range.
oOperation in a more critical explosion protection zone than specified on the type plate and in these operating instructions.
oOperation with explosive gases and vapours, where the ignition temperature is below the maximum specified surface
temperature.
oOperation with explosive dusts with minimum ignition temperature and the glow temperature are below the specified
maximum surface temperature.
oSubsequent alteration of the paint finish that does not comply with the requirements of the applicable ATEX standards.
oOverriding or removing safety equipment (e.g. pressure limitation valve)
oAdding and feeding unspecified or contaminated lubricants
oAdding and feeding lubricants that require written approval from Delimon or are generally prohibited (e.g. hazardous
substances or food fat)
oFilling and transporting lubricants whose temperature is above the maximum permissible ambient temperature.
oForeign bodies in the lubricant reservoir
oOperation in corrosive / aggressive environments without a suitable protective coating or enclosure
oSelecting an unsuitable installation site
oTampering on the pump (e.g. shutting down an outlet)
oReplacing original attachments with unsuitable components, e.g. motor with too high a power / rotation speed
2.12 Product modifications
Modification or alteration of the pump is prohibited. Any modification will have unpredictable influence on the safety and will lead
to the loss of the ATEX conformity.

Residual risk
Preventative / remedial measure
Creation of an explosive atmosphere due to the dust
circulation
Avoid dust accumulation by regular control and cleaning.
Select a place of installation with preferably a clean
environment and low dust exposure.
Heating of the lubricating points, which are undersupplied, to
the ignition temperature level due to non-detected
malfunction within the central lubrication system
The operator must examine critically whether operation
without appropriate automated system monitoring leads to a
potential hazard. If necessary, suitable remedial measures
must be taken.
Use in a potentially explosive atmosphere without testing the
potential equalisation for electrical continuity
The potential equalisation must be checked for continuity at
regular intervals. The operator defines the intervals. In any
case, the test must be carried out prior to commissioning and
after repairs / maintenance.
Generation of electrostatic charges, sparks, e.g. due to
components falling down or colliding with each other
Secure part against traps. If necessary, cover components to
prevent sparks from forming.
Use of isolating switching amplifiers in potentially explosive
atmospheres
Only install isolation amplifiers outside the potentially
explosive area.

3. Product description
3.1 Introduction
The FZ-A /FZ-B (ATEX version) grease / oil lubrication pump is a positively driven piston pump. The operating principle is
characterised by a very high level of reliability and constant delivery volume, even at a high back pressure. In contrast to other
piston pumps, only one central piston is required to supply up to 12 outlets due to a special design.
Unlike the standard version of the FZ pump, the ATEX version is only available with flange motor and reduction gear. The drive
types with free shaft end or pendulum lever are not available.
Difference: FZ-A and FZ-B pump (standard and ATEX version)
The two pumps only have a different pump body design. The FZ-B pump is available with 1 or max. 2 outlets and feeds 12 times or
2x 6 times the volume of the FZ-A pump due to internal volume combination.

3.6.2 Drive variants
The FZ pump (ATEX version) is equipped with a flange-mounted three-phase motor. Other drive types are not possible as opposed to
the standard version. There are two different drive positions to choose from:

3.6.3 Reservoir variants
Selection of the correct reservoir size depends primarily on the expected lubricant consumption. This should take the effort
required for topping up, which would be reduced by larger reservoir volumes, into account. On the other hand, the lubricant’s dwell
time in the reservoir must also be taken into consideration. An insufficient lubricant replacement frequency may have a negative
effect on the lubricating and feeding properties. The available installation space is also a selection criterion.
For 15 and 30 litre reservoirs, we advise using a reservoir support if the pump is exposed to vibrations or acceleration.
3.6.4 Accessories
The FZ pump can be equipped with a level monitoring system with 2 switching points for the use in zones 2 and 22 on request. For
the use in zone 1 (Gas Ex) the level monitoring is compulsory. The pressure limitation at each outlet is set to 160 bar as standard
in order to protect the pump and downstream components, which may only be approved for 160 bar. The pump can optionally be
supplied with a 200 bar pressure limitation.

3.7 Technical details
3.7.1 Functionality
The FZ pump is a positively driven piston pump. The centrally arranged piston (3) is driven by a worm wheel (1). It performs both
axial movements (stroke) and, simultaneously, rotary movements around its own axis. The piston’s rotational speed depends on the
selected gear ratio.
The lifting disc (2) has a cam on the top which, during the rotary movement, successively strikes against the six setting spindles (4)
arranged on the pump’s circumference, causing a piston suction stroke each time. The stroke movement and thus the delivery
volume can be varied at each setting spindle.
During the suction stroke, the lubricant flows from the suction chamber (S) into the piston’s vertical grooves and, from there, into
the ring channels (R). During the pressure stroke, the lubricant is fed from the ring channel and into the pressure channel (D) and
then into the outlet openings via a vertical groove.
3.7.2 Outlet location and labelling
The FZ-A pump can be configured with up to 12 outlets. Depending on the number, one pump body either with one row of outlets
(6x) or with two rows of outlets (12x), one above the other, is installed. Open outlets are provided with a screw fitting and pressure
relief valve on delivery. These are clearly identifiable. If there are fewer than 6 or 12 outlets, shut-off outlets are closed with a
sealing plug and there are no setting spindles available.

The outlets are arranged in a circle at increments of 60° and are visibly numbered on the pump body. Arrows indicate the
corresponding setting spindle that the delivery volume can be adjusted with. If there are more than 6 outlets, two outlets are
positioned in pairs, one on top of another (24 mm apart). In this case, the outlet volume can only be adjusted in pairs. This means
that regulation at outlet 1 also inevitably applies to outlet 7 below too.
3.7.3 Delivery volume per outlet:
The guaranteed pump delivery volume when using grease is 0.1 cm3per outlet and piston stroke. With low-viscosity lubricants such
as oil, the delivery volume can also be higher and reach max. 0.15 cm3/stroke. However, all subsequent volume calculations refer to
0.1 cm3. The delivery volume per outlet is independent of the total number of outlets.
The pump’s total delivery volume is then the sum of all outlets:
1 outlet
1x 0.1 cm3/ piston stroke
Total: 0.1 cm3/ piston stroke
2 outlets
2x 0.1 cm3/ piston stroke
Total: 0.2 cm3/ piston stroke
3 outlets
3x 0.1 cm3/ piston stroke
Total: 0.3 cm3/ piston stroke
…
…
12 outlets
12x 0.1 cm3/ piston stroke
Total: 1.2 cm3/ piston stroke
The effective delivery volume / time is determined by the choice of drive. More detailed information and calculations are provided
in the sections below for the relevant drive versions. The maximum possible delivery volume is 1.0 cm3per outlet / min (10
revolutions or strokes / min x 0.1 cm3).
3.7.4 Adjusting the delivery volume:
The FZ pump has 1 to 6 setting spindles depending on the configuration. If there are more than 6 outlets, a setting spindle
controls the delivery volume of the two outlets positioned one above the other. Engraved arrows clearly indicate the spindle –>
outlet association. The top and bottom outlets cannot, therefore, be regulated independently of each other. The pump is set to the
maximum delivery volume at all outlets on delivery. Numbers from 1 to 4 are engraved on the spindles (4 = maximum delivery
volume)

Important:
The spindle positions 1 –4 do not cause a proportional change in volume, i.e. position 2 is not the same as 50%, for example. The
actual change in the delivery volume very much depends on the lubricant used (suction behaviour) and must be tested under the
given conditions. When using grease, the setting spindle should not be turned to anything smaller than position 2!
Please proceed as follows to subsequently adjust the delivery volume:
Note: You can connect outlets externally using connected pipelines to
reduce the number of outlets or to specifically combine volumes.
3.7.5 Drive types in general
In contrast to the standard version, the ATEX version of the FZ pump is only available with a pre-assembled flange motor.

3.7.6 Drive with a flange motor and reduction gear
For the pump configuration with its own flanged drive a reduction gear is always required to reduce the motor’s rotation speed to
the feed piston’s permissible rotation speed. A 4-pole asynchronous motor whose shaft speed is slightly below that of the electric
drive rotating field (1,500 rpm) due to functional slip is used as standard. Our standard motor’s relevant shaft speed is 1,340 min-
1(at 50 Hz) and 1,610 m-1 (at 60 Hz), with which the following volume calculations were carried out.

WARNING
Loss of ATEX certification and risk of explosion
The ATEX certification of the FZ pump is only valid in combination with the flange-
mounted motor from the factory.
An unauthorised modification will result in the loss of the ATEX certification.
An unauthorised replacement of the motor with other performance data can lead to
damage to the pump.
An unauthorised replacement of the motor with different performance data may
result in damage to the pump.
3.7.7 Reservoir
The FZ pump offers different reservoir sizes, so it can be well adapted to the lubricant consumption. All reservoir options are made
of metal and are zinc-nickel coated. The reservoir top is bolted on all versions and may only be opened for maintenance purposes
and by authorised personnel. On request, a fill level switch (MIN/MAX) can be installed in the reservoir top (see the section entitled
‘Accessories’).
Note: When using in ATEX Zone 1, a fill level switch is mandatory.
A feed insert with scraper, which rotates while the pump is running, is installed in the reservoir base.
The rotation speed corresponds to the piston speed (max. 10 rpm). The scraper ensures regular
mixing of the lubricant and prevents deposits (when grease is used) on the inner wall of the reservoir,
which can occur especially if the lubricant remains in the reservoir for a long time.
A screen plate is installed in the reservoir base to protect the pump suction chamber against coarse
dirt.
WARNING
Hand injury due to the rotating scraper
Never reach into the reservoir while the pump is running. There
is a risk of hands and fingers being crushed and cut off. Only
refill lubricant via the filling nozzle! No unauthorised access!
