2 About this pump
The Makro TZ diaphragm metering pump is fitted as standard with a 0.75
kW wide range AC motor. The stroke length can be adjusted between
0...10 mm. The acrylic resin painted cast housing can be combined with
up to 16 liquid end sizes and 5 gear reduction ratios (integrated in the spur
geared motor). The liquid ends are available in various material combina‐
tions which can be matched to the feed chemicals being metered.
The Makro TZMb is equipped as standard with a multi-layer diaphragm
and diaphragm rupture sensor.
The Makro TZ externally mounted metering pump can be combined with
the Makro TZ main power end to form a double or multiple pump. A main
power end can be combined with up to four add-on power ends.
One power end can be used both as a single or a double head version.
The double head versions are fitted with a second liquid end which oper‐
ates in push-pull mode (Boxer principle).

The following signal words are used in these operating instructions to
denote different severities of danger:
Signal word Meaning
WARNING Denotes a possibly dangerous sit‐
uation. If this is disregarded, you
are in a life-threatening situation
and this can result in serious inju‐
ries.
CAUTION Denotes a possibly dangerous sit‐
uation. If this is disregarded, it
could result in slight or minor inju‐
ries or material damage.
The following warning signs are used in these operating instructions to
denote different types of danger:
Warning signs Type of danger
Warning – hand injuries.
Warning – high-voltage.
Warning – flammable substances.
Warning – hot surface.
Warning – danger zone.
nThe pump may only be used to meter liquid metering chemicals.
nIn potentially explosive atmospheres in zone 1, device category II 2G
of explosion group II C, the pump must only be operated with the
appropriate nameplate (and the respective EC Declaration of Con‐
formity) for pumps for potentially explosive atmospheres complying
with Directive 94/9/EC in accordance with the European guidelines.
The explosion group, category and degree of protection declared on
the marking must correspond with or be better than the given condi‐
tions in the intended field of application.
nThe pump may only be started up after it has been correctly installed
and commissioned in accordance with the technical data and specifi‐
cations contained in the operating instructions.
nThe general limitations with regard to viscosity limits, chemical resist‐
ance and density must be observed - see also ProMinent resistance
list (In the product catalogue or at
www.prominent.com
)!
nAny other uses or modifications are prohibited.
nPumps without the relevant nameplate (and the respective EC Decla‐
ration of Conformity) for pumps for potentially explosive atmospheres
must never be operated in potentially explosive atmospheres.

nThe pump is not intended for the metering of gaseous media or solids.
nThe pump is not intended for unprotected outside use.
nThe pump is only approved to meter flammable liquids, if the operator
takes appropriate safety measures.
nThe pump should only be operated by trained and authorised per‐
sonnel, see also
Ä ‘Qualification of personnel’ on page 9
.
nYou are obliged to observe the information contained in the operating
instructions at the different phases of the device's service life.

Explanation of the terms:
Technical personnel
A qualified employee is deemed to be a person who is able to assess the
tasks assigned to him and recognise possible dangers based on his/her
technical training, knowledge and experience, as well as knowledge of
pertinent regulations.
Note:
A qualification of equal validity to a technical qualification can also gained
by several years employment in the relevant work area.
Electrical technician
Electrical technicians are deemed to be people, who are able to complete
work on electrical systems and recognize and avoid possible dangers
independently based on their technical training and experience, as well as
knowledge of pertinent standards and regulations.
Qualification of personnel
Safety chapter
9
Electrical technicians should be specifically trained for the working envi‐
ronment in which the are employed and know the relevant standards and
regulations.
Electrical technicians must comply with the provisions of the applicable
statutory directives on accident prevention.
Instructed person
An instructed person is deemed to be a person who has been instructed
and, if required, trained in the tasks assigned to him/her and possible dan‐
gers that could result from improper behaviour, as well as having been
instructed in the required protective equipment and protective measures.
Service
Customer Service department refers to service technicians, who have
received proven training and have been authorised by ProMinent or Pro‐
Maqua to work on the system.
WARNING!
Warning of dangerous or unknown feed chemical
Should a dangerous or unknown feed chemical be used: It
may escape from the hydraulic components when working
on the pump.
– Take appropriate protective measures before working on
the pump (e.g. safety glasses, safety gloves, ...).
Observe the safety data sheet for the feed chemical.
– Drain and flush the liquid end before working on the
pump.
WARNING!
Danger from hazardous substances!
Possible consequence: Fatal or very serious injuries.
Please ensure when handling hazardous substances that
you have read the latest safety data sheets provided by the
manufacture of the hazardous substance. The actions
required are described in the safety data sheet. Check the
safety data sheet regularly and replace, if necessary, as the
hazard potential of a substance can be re-evaluated at any
time based on new findings.
The system operator is responsible for ensuring that these
safety data sheets are available and that they are kept up to
date, as well as for producing an associated hazard assess‐
ment for the workstations affected.
CAUTION!
Warning of feed chemical spraying around
Feed chemical can spray out of the hydraulic components if
they are manipulated or opened due to pressure in the liquid
end and adjacent parts of the system.
– Disconnect the pump from the mains power supply and
ensure that it cannot be switched on again by unauthor‐
ised persons.
– Depressurise the system before commencing any work
on hydraulic parts.
