ply version, hereinafter referred to as LUB-V, safely and as intended. In the event that supple-
mentary sheets are attached to these instructions, the information and data contained in the
supplementary sheets are valid and replace the corresponding information in this user ma-
nual. Any contradictory information contained in this user manual thus becomes invalid.
If you have any questions regarding special applications, please contact Gruetzner GmbH.

The LUB-V is designed as an extremely compact double piston pump for autonomous operation
with grease as the lubricant. The two pistons run force-controlled and counter-rotating. The LUB-
V is available as a version with one lubricant outlet or as a version with two lubricant outlets. The
outlets are secured by an integrated non-return valve. Approx. 0.15 ml of lubricant is pumped
during each dispensing operation; multiple dispensers can be set one after the other.
The display on the front panel displays the various operating states; further information (empty
level tracking, empty cartridge, error) can be read.
The present Lubricus V as power supply version has an electrical interface. The supplied activa-
tionandprogrammingkeycanbeusedtoadjusttheoperationmodeandthequantityoflubricant
pumped per time in order to supply the lubrication point with the ideal quantity of lubricant.
3.2 Nameplate and designation
The nameplate of the LUB-V is visibly attached to the side of the pump itself. There the CE mark
and the serial number of the LUB-V are visible. Refer to Fig. 1 for the location of the nameplate
and serial number.
3.3 Scope of delivery
The LUB-V is available in several different versions. They differ in the design (housing for 250 ml
cartridge or housing for 400 ml cartridge), the number and type of lubricant outlets and the scope

4. Transport and storage
4.1 Packaging
The LUB-V is delivered in an outer packaging (cardboard box) and - depending on the scope of
delivery with a lubricant cartridge and other accessories - in the same package. To protect them
frommoistureanddirt,theyarealsopackedinPElms.
Dispose the packaging materials at the designated disposal points in compliance with the rele-
vant national and company regulations.
After receiving the LUB-V, check the delivery note for completeness and correctness.
Any missing parts or damage must be reported immediately to the forwarding agent, the insu-
rance company or Gruetzner GmbH in writing.
4.2 Transport
NOTICE
Hard shocks, e.g. due to falling or setting down too hard, can damage the
LUB-V.
(Do not throw the LUB-V.
(When using lifting equipment, only use hoists and load handling attach-
ments in perfect condition and with su󰀩cient load capacity.
(The permissible lifting weight of the lifting device must not be excee-
ded.
4.3 Storage
Store the LUB-V in its original packaging in a vertical position in a dry, frost-free environment at
an ambient temperature of +5°C to + 30°C. The maximum storage time in unopened condition is
2 years.
The so-called „First-In-First-Out-Principle“ (FiFo) is recommended for storage logistics.

5. Mounting
5.1 Preparations
Before starting to work, inform yourself in detail about the LUB-V using this user manual; in par-
ticular about the general safety instructions (section 2.7). Prepare the installation site carefully.
NOTE
Pressurised air can damage the seals of the LUB-V and can transport dirt
and foreign matter into the LUB-V or the lubricant.
(Do not use pressurised air.
(Make sure that there is no coarse dirt in the mounting area.
5.2 Mechanical mounting
Two through holes are provided on the housing for
mounting the LUB-V at the intended mounting lo-
cation.
Fasten the LUB-V using two DIN 912 socket head
screws of size M6x35 or longer.
Secure the screws with suitable threadlocker.
Suitable mounting brackets and plates are also
available as accessories.

5.3 Mounting height
When selecting the mounting location, observe the minimum mounting heights required for the
LUB-V in the version with 250 ml cartridge volume or 400 ml cartridge volume for disassembly
and assembly of the upper housing.

16
1. Remove the housing from the power unit of the
LUB-V.
Loosen the retaining ring from the power unit by
turning it counterclockwise.
Separate the upper housing from the LUB-V.
For easier loosening, grip the retaining ring on the
right and left outside.
Make sure that no dirt, water or foreign bodies en-
ter/s the lubricant inlet.
2. Mounting the lubricant cartridge
Unscrew the lubricant cartridge cap counterclock-
wise and pull it o󰀨.
 Place the lled lubricant cartridge on the LUB-V
with the label facing forwards.
Screw the lubricant cartridge clockwise onto the
LUB-V.
The end position is reached after two full rotations
when the label of the lubricant cartridge is in align-
ment with the front of the LUB-V.
5.4 Mounting of the LUB-V

17
4. Remove the protective cap on the side of the LUB-
V.
Remove the black protective cap in the direction of
the arrow from the side of the electrical M12x1 inter-
face.
3. Assembling the upper housing on the power unit
of the LUB-V.
Place the dismantled housing on the LUB-V and
press it onto the power unit.
Fasten the housing to the power unit by turning the
retaining ring clockwise.
For easier fastening, grip the retaining ring on the
right and left outside.
The retaining ring must snap into place when turn-
ing and be completely tightened.

18
5. Connect the electrical interface
Connect the LUB-V to the external power supply or
controller via the M12x1 interface on the side of the
LUB-V using a suitable connecting cable.
Depending on the application, connection cables
with straight or angled socket can be used.
Please refer to chapter 7.1 or chapter 8.1 for the
condition of the connection cable.
DANGER
Defective or faulty electrical connections or unauthorized live components
can lead to serious injuries or even death.
(Haveallelectricalconnectionworkcarriedoutbyqualiedpersonnel
only.
(Replace damaged cables or plugs immediately.
(Beforecarryingoutanyelectricalinstallationwork,observetheve
safety rules of electrical engineering:
- Unlocking
- Secure against unintentional restarting.
- Check that there is no voltage.
- Ground and short-circuit.
- Cover adjacent live parts.
DANGER
Machine elements that are not lubricated can cause failures resulting in
serious injury or even death.
(Never operate the LUB-V without the upper housing. Especially when
changing the cartridge or during start-up, make sure to remount the
upper housing after disassembly.
