4. Description of function
4.1 Drive assembly
4.1.1 Solenoid-based drive assembly
The unit is actuated by a d.c. solenoid-based exciter screwed to the pump case. The
solenoid is energised from an external power supply. For that purpose, however, an exter-
nal control is required.
4.1.2 Pneumatic drive assembly
The unit is driven by a pneumatic piston screwed to the pump case. The piston is actuated
via a flange-mounted 3/2-directional control valve. The 3/2-solenoid valve is energised from
an external power supply. For that purpose, however, an external control is required.
4.2 Working mode of the version GMV-B
3
1
6
78
The piston pump consits of a pump housing with delivery piston 8, an electric or pneumatic
drive 1and an cartridge reservoir 3.
Suction phase:
The delivery piston 8is put back by means of spring tension. Due to the negative pressure
generated, the lubricant will be sucked out of the cartridge reservoir 3.
Pressure phase:
When the drive 1is operated , the delivery piston 8convey the lubricant to the outlet 6via
non-return valve 7.

Operating manual GMV-B Page 14 of 28 B0823
4.3 Level monitoring F
The cartridge container is equipped with a filling level control. Switch
output is an NC contact, closed at minimum level. The connection is
made by means of a plug connection M8x1, 3-pin.
4.4 Function control 1
As a function control an inductive proximity switch is mounted on the
bottom. This proximity switch controls the piston movement
continuously and reports a function failure. Switch output open at idle
position.
The connection is made by means
of a plug connection M8x1, 3-pin.
5. Safety instructions
5.1 Fundamental
The unit is shipped from the works in faultless condition and guarantees high technical

5.3 Safety devices
The unit is inherently safe due to its design.
5.4 Accident prevention
Stick to these measured to prevent accidents:
Hinder unauthorised persons from access to the unit.
Keep foreign persons away from dangerous areas and dangerous sites.
Inform repeatedly present foreign persons on residual dangers. As for residual
dangers, see section "Residual dangers".
5.5 Residual dangers
As regards the unit itself, there are no residual dangers for persons and equipment if that unit
is used according to its design as well as intended purpose, and the specified cycles as well
as measures for maintenance and service are kept.
5.6 Improper use
If the unit is used for purposes other than specified and agreed upon, there is
danger for heavy damage to both persons and equipment.
Referring to experience, improper use may include, for example:
Supply of highly flammable or explosive media.
Supply of media, which are able reacting with materials the unit has been made of.
Supply of foodstuff.

Operating manual GMV-B Page 16 of 28 B0823
5.7 General safety regulations and duties
In general, using the unit the following safety regulations and duties are to be
complied with:
Consider the generally accepted rules for labour safety. This is also true,
in addition, for the current basic rules on labour safety and accident
prevention on the site of operation.
As user comply with the regulations for the usage of working equipment.
Operate the unit in clean and faultless state only.
Never remove, modify, bridge or neglect any protection, safety and moni-
toring equipment, in no case.
Do not reconstruct or change the unit.
Report faults or damage to the owner.
Assemble original spare parts only for repair.
The user has to inspect and maintain in good condition all the protection,
safety and monitoring equipment on a regular basis.
After each repair, make sure that the unit is in faultless state and take a
test run.
5.8 Exclusion of liability
If damage to persons, equipment, environment and assets occurs due to ignoring this oper-
ating manual regardless if intentionally or unintentionally, WOERNER shall not be held re-
sponsible. No claim for warranty will be accepted. This is also true for any consequential
damage.

6. Transport, installation, start-up and putting out of operation
6.1 Transport
Transport the unit cautiously to its destination. For that purpose, make use of proper
equipment.
6.2 Unpacking
Lift the unit carefully from the packaging and place the unit on a stable as well as plane
support.
Note! Consider that inside the unit and attached components according to
the bill of delivery there might be residues of blue-coloured test oil.
6.3 Installation
The unit is prepared for being mounted on wall by means of two screws M6. The mounting
area has to be that stable to absorb the weight of the unit including the filled cartridge. In
addition, make sure that the mounting surface is vertical and plane.
Drilling pattern for wall mounting:
6.4 Power supply and switching-on
6.4.1 Electric drive assembly
Important! Compare the indications of the local voltage supply with the tech-
nical data of the unit.
Important! Lay the mains cable that way to prevent any unintentional tearing
off.
Important! Skilled electricians are the only ones allowed to intervene in
electrical installations according to DIN VDE 1000-10.

Operating manual GMV-B Page 18 of 28 B0823
Connect the unit to the voltage supply and control.
Before starting-up, double-check the installation for correct electrical connection.
Warning!
There is danger to life when intervening into the electrical installations!
6.4.2 Pneumatic drive assembly
Important! Compare the indications of the local compressed-air supply
system with the technical data of the unit.
Important! Lay the pneumatic lines that way to prevent any unintentional
tearing-off.
Connect the unit to the compressed-air supply system and control.
Before starting-up, double-check the installation for correct connection.

Operating manual GMV-B Page 19 of 28 B0823
6.5 Start-up
The function of the unit was checked in the works. Thus, the unit is ready for use and can be
connected to the local media supply systems.
Important! Consider the safety instructions in section "Power supply and
switching-on".
First fill lubricant and then start the pump unit, in every case.
The filling level must not be lower than 10-15 mm above the
reservoir’s bottom edge.
Actions to be taken for start-up:
a) Filling the unit with lubricant
Replacement of the cartridge:
Unscrew reservoir and pull back piston bar up to stop. Then insert both sides opened grease
cartridge into reservoir, and screw reservoir on.
Screw reservoir on and push the piston bar back in again completely.

Operating manual GMV-B Page 20 of 28 B0823
b) Venting of the cartridge reservoir
As for bleeding the cartridge / container, loosen the bleeding plug screw and wait until the
medium emerges without bubbles from the bleeding bore.
c) Venting of the unit
Vent both the line and unit to get the unit working satisfactorily. For that purpose, actuate
the drive assembly as many times as necessary to have the lubricant emerging at the outlet
without air bubbles.
b) Venting of the line feeding the lubricating point
Make sure that the line feeding the lubricating point has been cleaned and
enables free flow!
Link the line feeding to the lubricating point with the unit, actuate the unit as many times as
necessary to have the lubricant emerging from the line without air bubbles. This action can
be shortened when the tube ascends towards the outlet.
6.6 Putting out of operation
The unit is put out of operation by switching-off and deinstalling from the external power
supply.
Skilled electricians are the only ones allowed to intervene in electrical
installations according to DIN VDE 1000-10.
Vent screw
