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 handling of the
pump.
Take appropriate protective measures 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 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 assessment for the workstations affected.
CAUTION!
Warning of feed chemical spraying around
Feed chemical can spray out of the hydraulic compo‐
nents 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 mate‐
rials and the ProMinent Resistance List when
selecting the feed chemical - see the ProMinent
Product Catalogue or visit ProMinent.
CAUTION!
Danger of personnel injury and material damage
The use of untested third party parts can result in per‐
sonnel injuries and material damage.
Only fit parts to metering pumps, which have been
tested and recommended by ProMinent.
Safety information
Safety Chapter
10
CAUTION!
Danger from incorrectly operated or inadequately main‐
tained pumps
Danger can arise from a poorly accessible pump due to
incorrect operation and poor maintenance.
Ensure that the pump is accessible at all times.
Adhere to the maintenance intervals.
WARNING!
An on/off switch may not be fitted on the pump,
dependent on the identity code and installation.
Warning labels
This warning sign is affixed to the motor:
Ensure that the warning sign is always fitted and clearly visible.
All isolating protective equipment must be installed for operation:
n Drive front cover
n Motor fan cowling
n Motor terminal box cover
n Hood
In exactly the same way, plug all relays, modules and options into the
hood - if available.
Only remove them when the operating instructions request you to do so.
In the event of an electrical accident, disconnect the mains cable from the
mains or press the emergency cut-off switch fitted on the side of the
system!
If feed chemical escapes, also depressurise the hydraulic system around
the pump as necessary. Adhere to the safety data sheet for the feed
chemical.

3 Storage, Transport and Unpacking
WARNING!
Only return the metering pump for repair in a cleaned
state and with a flushed liquid end - refer to the chapter
"Decommissioning"!
Only return metering pumps with a completed Decon‐
tamination Declaration form. The Decontamination Dec‐
laration constitutes an integral part of an inspection /
repair order. A unit can only be inspected or repaired
when a Declaration of Decontamination Form is sub‐
mitted that has been completed correctly and in full by
an authorised and qualified person on behalf of the
pump operator.
The "Decontamination Declaration Form" can be found
at www.prominent.com.
WARNING!
Slings can tear
ProMinent only supplies “non-reusable slings” in accord‐
ance with DIN EN 60005. They can tear with repeated
use.
Destroy and remove the slings as soon as the pump
has been lifted into its final position.
CAUTION!
Danger of material damage
The device can be damaged by incorrect or improper
storage or transportation!
The unit should only be stored or transported in a
well packaged state - preferably in its original pack‐
aging.
Only transport the unit when the red gear bleeding
plug is pushed in.
The packaged unit should also only be stored or
transported in accordance with the stipulated
storage conditions.
The packaged unit should be protected from mois‐
ture and the ingress of chemicals.
Compare the delivery note with the scope of supply:
Personnel:
n
Technical personnel
1. Plug the caps on the valves.
2. Check if the red gear bleeding plug is pushed in.
3. Preferably place the pump standing vertically on a pallet and secure
against falling over.
4. Cover the pump with a tarpaulin cover - allowing rear ventilation.
Store the pump in a dry, sealed place under the ambient conditions
according to chapter "Technical Data".

5 Functional description
5.1
Pump
The metering pump is an oscillating diaphragm pump, the stroke length of
which can be adjusted. An electric motor drives it. The slide rod transmits
the stoke motion to the diaphragms.
The stroke movement of the displacement body is continuously detected
and regulated so that the stroke is performed according to a previously set
metering profile - see chapter.
‘Metering’
‘setting’
.
The following metering profiles are available:
n Normal
n Metering optimised
n Priming optimised
Every metering profile is ineffective below the switch-
over frequency for Start/Stop mode.

- Suction stroke
Metering optimised
With a metering optimised metering profile, the discharge stroke is elon‐
gated and the suction stroke is executed as quickly as possible. This set‐
ting is for example suitable for those applications that require optimum
mixing ratios and the most continuous chemical mixing possible.

Functional description

With a priming optimised metering profile, the suction stroke is elongated
as much as possible, which facilitates the precise and problem-free
metering of viscous and gaseous media. Select this setting to minimise the
NPSH value as well.
5.2
Liquid end
The diaphragm (2) hermetically shuts off the pump volume of the dosing
head (4) towards the outside. The suction valve (1) closes as soon as the
diaphragm (2) is moved in to the dosing head (4) and the feed chemical
flows through the discharge valve (3) out of the dosing head. The dis‐
charge valve (3) closes as soon as the diaphragm (2) is moved in the
opposite direction due to the vacuum pressure in the dosing head and
fresh feed chemical flows through the suction valve (1) into the dosing
head. One cycle is thus completed.

5.3 Bleed valve and integrated relief valve
Turning the rotary dial (3) on the bleed valve to "open" causes it to open
and the liquid end can be bled. Or it is used as a priming aid for priming
against pressure. The feed chemical flows out through the hose connec‐
tion (5), e.g. into a storage tank.
The integral relief valve operates in the "close" position as a simple,
directly controlled relief valve. As soon as the pressure exceeds the pres‐
sure value, which is preset using the large spring (1), it lifts the ball (2).
The feed chemical flows out through the hose connection (5), e.g. into a
storage tank.

Bleed valve
Integral relief valve
Functional description
19
The integral relief valve can only protect the motor and the gear, and then
only against impermissible positive pressure that is caused by the
metering pump itself. It cannot protect the system against positive pres‐
sure.
The integral relief valve works as a bleed valve as soon as the rotary dial
(3) is turned to "open": The valve opens and the liquid end can be bled. Or
it is used as a priming aid for priming against pressure.

5.4 Multi-layer safety diaphragm
With the visual diaphragm rupture sensor, the lowered red cylinder (6)
springs forward beneath the transparent cover (7) so that it then becomes
clearly visible
Fig. 12.
With the electrical diaphragm rupture sensor, a switch is switched. A con‐
nected signalling device must signal the diaphragm rupture.
Fig. 12: Visual diaphragm rupture sensor, triggered and untriggered
The electrical diaphragm rupture sensor is connected to the "diaphragm
rupture indicator" terminal. If a diaphragm ruptures, the red LED "Fault"
display lights up on the pump and the identifier "Error" and
‘dia’
flash on
the LCD screen.
5.5 Operating modes
