Safety information
WARNING!
Warning about personal and material
damage
The pump can start to pump, as soon
as it is connected to the mains voltage.
– Install an emergency cut-off switch
in the pump power supply line or
integrate the pump in the emer‐
gency cut-off management of the
system.
WARNING!
Danger of electric shock
A mains voltage may exist inside the
pump housing.
– If the pump housing has been
damaged, you must disconnect it
from the mains immediately. It
may only be returned to service
after an authorised repair.
WARNING!
Warning of hazardous feed chemical
Should a dangerous feed chemical be
used: it may escape from the hydraulic
components when working on the
pump, material failure or incorrect han‐
dling of the pump.
– Take appropriate protective meas‐
ures before working on the pump
(e.g. safety glasses, safety
gloves, ...). Adhere to the material
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 haz‐
ardous 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 assessment for the
workstations affected.
Safety chapter

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 unauthorised persons.
–
Depressurise the system before
commencing any work on
hydraulic parts.
CAUTION!
Warning of feed chemical spraying
around
An unsuitable feed chemical can
damage the parts of the pump that
come into contact with the chemical.
– Take into account the resistance
of the wetted materials and the
ProMinent Resistance List when
selecting the feed chemical - see
the ProMinent Product Catalogue
or visit ProMinent.
CAUTION!
Warning of feed chemical spraying
around
The metering pump can generate a
multiple of its rated pressure. Hydraulic
parts can rupture if a discharge line is
blocked.
– Correctly install a relief valve in the
discharge line downstream of the
metering pump.
CAUTION!
Danger of personnel injury and material
damage
The use of untested third party parts
can result in personnel injuries and
material damage.
– Only fit parts to metering pumps,
which have been tested and rec‐
ommended by ProMinent.
CAUTION!
Danger from incorrectly operated or
inadequately maintained pumps
Danger can arise from a poorly acces‐
sible pump due to incorrect operation
and poor maintenance.
– Ensure that the pump is acces‐
sible at all times.
–
Adhere to the maintenance inter‐
vals.

Circuit breaker
The driver motor is fitted with a circuit breaker,
which automatically switches off the motor
when it overheats to more than 106 °C.
The circuit breaker switches the pump on again
once the motor has cooled down.
Information in the event of an emergency
In an emergency, either pull out the mains plug
or press the emergency-off switch, installed by
the customer, or disconnect the pump in line
with the emergency-shut-down guidelines for
your system!
If feed chemical escapes, also ensure that the
pump's hydraulic environment is at atmospheric
pressure. Adhere to the material safety data
sheet for the feed chemical.
Sound pressure level
Sound pressure level LpA < 70 dB according to
EN ISO 20361
at maximum stroke length, maximum stroke
rate, maximum back pressure (water)

3 Storage, Transport and Unpacking
Safety Information
WARNING!
Only return metering pumps for repair
in a cleaned state and with a flushed
liquid end - refer to "Decommissioning!
Only return metering pumps with a
completed Decontamination Declara‐
tion form. The Decontamination Decla‐
ration constitutes an integral part of an
inspection / repair order. A unit can only
be inspected or repaired when a Decla‐
ration of Decontamination Form is sub‐
mitted that has been completed cor‐
rectly and in full by an authorised and
qualified person on behalf of the pump
operator.
The "Decontamination Declaration
Form" can be found on our homepage.
CAUTION!
Danger of material damage
The device can be damaged by incor‐
rect or improper storage or transporta‐
tion!
– The unit should only be stored or
transported in a well packaged
state - preferably in its original
packaging.
–
The packaged unit should also
only be stored or transported in
accordance with the stipulated
storage conditions.
– The packaged unit should be pro‐
tected from moisture and the
ingress of chemicals.
Ambient conditions
Ambient conditions - refer to "Technical Data"
chapter.

5 Functional description
5.1 Power end
The cam for the stroke movement is guided in
an eccentric disc. Pumps of this size do not
therefore require conventional return springs –
the suction and pressure stroke are positively
driven.
The stroke length can be adjusted by a latched
slide (9) from 100% to 0 in increments of 10%.
The diaphragm is always deflected from the
neutral centre position, producing a smooth
sinusoidal stroke motion.
5.2
Liquid End
The dosing process is performed as follows:
The diaphragm is pressed into the dosing head;
the pressure in the dosing head closes the suc‐
tion valve and the feed chemical flows through
the discharge valve out of the dosing head. The
diaphragm is now drawn out of the dosing
head; the discharge valve closes due to the
negative pressure in the dosing head and fresh
feed chemical flows through the suction valve
into the dosing head. One cycle is completed.

6 Assembly
WARNING!
The IP 23 protection against moisture
and accidental contact only applies to
horizontal pump bases with vertically
installed pumps.
CAUTION!
When assembling the pump, ensure
that there is sufficient room around the
pump for operation, maintenance,
repairs and quick disconnection of the
mains plug.
Capacity too low
Vibrations can disturb the liquid end
valves.
–
Secure the metering pump to
ensure that no vibrations can
occur.
Capacity too low
If the liquid end valves are not upright,
they cannot close correctly.
–
Ensure that the discharge valve is
upright.
Assemble the metering pump on a
storage tank or a bracket using screws
and U-washers (Ø 5 mm).

Safety notes
CAUTION!
Warning of feed chemical spraying
around
An unsuitable feed chemical can
damage the parts of the pump con‐
tacted by the chemical.
– Take into account the resistance
of the materials which will come
into contact with the chemical
when selecting the feed chemical see the ProMinent Product Cata‐
logue or visit www.prominent.com.
CAUTION!
Warning of feed chemical spraying
around
Pumps which are not fully installed
hydraulically can pump feed chemical
from the outlet opening of the discharge
valve as soon as they are connected to
the mains power supply.
– First install the pump hydraulically,
then electrically.
–
In the event that you have failed to
do so, press the On/Off switch (on
site) or the Emergency Stop
switch.
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 unauthorised persons.
–
Depressurise the system before
commencing any work on
hydraulic parts.
CAUTION!
Danger from rupturing hydraulic com‐
ponents
Peak loads during the dosing stroke
can cause the maximum permissible
operating pressure of the system and
pump to be exceeded.
– The discharge lines are to be
properly designed.
