1.1Notes on Safety
WARNING
• Immediately switch off the pump in the case of emergency!
Use the pump power switch or an emergency stop switch in your working environment!
• When installing the metering pump also observe the installation instructions for
devices in explosive areas; for Europe the European operator directive 99/92/EC
(ATEX137) and the ATEX Product Directive 94/9/EC (ATEX 95), implemented in Germany
by the new health and safety legislation!
• When using the metering pump for metering flammable media, observe (in Europe) the
European Operator Guideline 99/92/EC (ATEX 137, previously ATEX118a), implemented
in Germany with the new operating safety directive and the German dangerous
chemicals directive.
• Observe also all relevant standards e.g. DIN EN 60079-10/14 and DIN VDE 60079-11 for
installations in explosion-threatened areas and DIN VDE 0118 for the installation of
electrical equipment in explosion-threatened areas by day.
• Note all national directives which apply to the installation when installing outside
Germany.
CAUTION
• Pumps must be accessible at all times to facilitate operation and maintenance.
Do not obstruct or block access routes!
• Only specially trained and authorized persons are permitted to maintain and repair
metering pumps and their peripheral equipment!
• Always depressurize the liquid end first before carrying out any work on the pump!
• If hazardous or unknown metering media are used, discharge and flush the liquid end
before carrying out any work on the pump!
• Observe the safety data sheets of the metering liquids!
• Always wear protective clothing (goggles, gloves) when handling hazardous or
unknown liquids! This applies in particular to working on the liquid end!
®
• Assembly of ProMinent

consists of the main components
2.1Functional principle
Metering is based on the pulse burst principle:
A pulse produces a magnetic field around the solenoid,
the solenoid attracts a moving thrust piece,
as a result, the diaphragm displaces the medium in the liquid end via a pressure control valve,
the valve closes on the intake side.
The magnetic field decays on completion of the switch-on pulse,
the thrust piece of the solenoid is reset by a reset spring,
the diaphragm returns to its initial position, thus initiating an intake stroke,
which closes the pressure valve and the media is drawn in on the intake side.
The diaphragm rupture signalling system monitors the leak-tightness of the operating
diaphragm.
The liquid end of EXBb with diaphragm rupture signalling has instead of only one operating
diaphragm an additional diaphragm comprising the operational diaphragm and an additional
safety diaphragm, and is equipped with an intrinsically safe diaphragm rupture sensor (see
figure 1).
Page 10
ProMinent
®
Page 11
Design and Function
The safety diaphragm is situated between the top plate and the spacer plate and forms a sealed
interim chamber with the working diaphragm.
FunctionIt serves to monitor ruptures in the working diaphragm and protects the power end from
corrosion and the environment from chemical leaks in the case of diaphragm rupture.
Even after diaphragm rupture, this liquid end can continue to operate in emergency mode at full
working pressure and without leaks until the diaphragm is changed.

fig.: 1
IMPORTANT
If the diaphragm ruptures, an electrical signal is triggered when the system back pressure
reaches approx. 2 bar.
IMPORTANT
Precise pump feed cannot be guaranteed after a working diaphragm rupture.
2.3Feed rate
The delivery capacity is determined by the stroke length and the stroke frequency (rate).
The stroke length can be steplessly adjusted with the control knob for stroke length (14) during
operation from 100 % to 10 % and then locked. The maximum stroke length is 1.25 mm, 0.63
mm for type EXBb_1000.
A setting of 0 to 110 (120) stroke/min can be set manually with the control knob for stroke
frequency (rate) (16).
At a maximum stroke length and rate and a max. backpressure of 1.5 bar to 25 bar, the
diaphragm-operated metering pumps deliver at a rate of 0.2 l/h to 60 l/h.
The controlling pulse is internally generated, stroke length and stroke rate can be manually
adjusted using the control buttons on the operating panel.
The controlling pulse is externally generated, from potential-free or semiconductor contacts and
fed to the drive unit via the “external control” jack; examples are contact water meter or
DULCOMETER® controls.
Versions “Analog control x - 20 mA”
(Identity code characteristic “Control type”: 2, 3, 5, 6):
An external, analogue signal is fed to the drive unit via the “External control” jack;
the stroke rate changes proportionally according to the 0 .. 20 mA or 4 .. 20 mA signal.
As for version “Internal stroke rate setting”, however there is also the possibility of switching the
metering on and off via an external semiconductor contact or potential-free contact.
NOTE
All control types, that can be controlled via an input, can be supplied with an “External
control” input of “non-intrinsically safe” or “intrinsically safe” type [i, a].

Better than ± 2 %
under constant conditions and min. 30 % stroke length;
observe following notes:
• All specifications refer to metering measurements with water at 20 °C.
• Constant backpressure, above 1 bar if possible.
• If metering takes place via a free outlet, a pressure retention valve must be used to generate
a backpressure of min. 1.5 bar (refer to the installation examples).
• Wherever possible, lay intake and metering lines with a constant rising gradient.
• If the liquid level of the supply tank is above the pump during operation, admission pressure
will be applied on the intake side; in this case, the backpressure should be so high that there
is a minimum differential pressure of 1.5 bar otherwise a pressure retention valve or a springloaded injection valve with corresponding admission pressure must be used.
NOTE
A pressure retention valve or a spring-loaded injection valve is not an absolutely tightclosing shut-off element. For this reason, an intake valve which is closed when the
metering pump is at a standstill, must be installed if admission pressure is applied on the
intake side.

5.2Installing Hose Lines
IMPORTANT
• Lay and secure intake and delivery lines such that they cannot chafe.
• Lay intake and delivery lines such that they are free of mechanical stress.
• Arrange all lines such that the pump and liquid end can be removed laterally if required.
• When metering extremely aggressive or hazardous media, a venting facility with return
into the supply tank as well as a shut-off valve must be provided on the delivery and
intake sides.
• Ensure all connections are tight:
only use the clamping rings and hose sockets as specified for the relevant hose
diameter, only use original hoses with specified hose dimensions and wall
thickness.
•Avoid reductions in hose sizes: use the next higher line cross-section for long hose
lines and viscous media or install a compressed air vessel or diaphragm pulsation
damper!

5.2.1 Installing the Intake Line
NOTE
• The intake line should be as short as possible.
• Fit intake line in upright position in order to avoid air bubbles forming.
• Wherever possible use pipe bends and not elbows for bends in the intake line.
• Select cross section and length such that the vacuum which occurs during intake does
not reach the vapour pressure of the medium to be metered. In extreme cases,
excessively high vacuum on the intake side is reflected in collapse of the liquid column
or by an incomplete return stroke.
• Do not exceed the permissible admission pressure on the intake side.
• Note: Suction lift x medium density ≤ max. suction lift in m water column
• Refer to the installation examples.

• Refer to installation examples!
When metering with atmospheric discharge, a metering valve with 0.5 bar response pressure
should be mounted at the end of the line. Or a back-pressure valve should be mounted directly
onto the liquid end in order to create and maintain a counter-pressure of approx. 1.5 bar.
If the level of the fluid of the supply tank is above the pump in operating condition, the response
pressure is on the suction end. In this case the counter-pressure should be sufficiently high such
that a minimum differential pressure of 1.5 bar exists. If this is not the case a back-pressure
valve or a spring-loaded metering valve with the respective response pressure should be used.

delivery line to burst!
An overflow valve should be installed in order to avoid this, e.g. a ProMinent multifunction valve.
not exceed the max. permissible operating pressure. Check length and cross-section.
If necessary, install an overflow valve, compressed air vessel or diaphragm pulsation
damper.
NOTE
A back-pressure valve or a spring-loaded metering valve is not an absolutely leakproof
shut-off device!
On the suction end a stop valve is therefore to be installed which is closed when the
metering pump is idle.
5.2.3 Installing the Bypass Vent Line (see fold-out page)
The liquid end of the pump types 1000 - 0417 NP and PP is equipped with a vent valve (5) with
bypass (6).

왘 Cut the bypass line to size such that it is not submerged in the metering medium.
• The metering pump must be electrically installed by authorised, “skilled” personnel
only.
• When installing the metering pump also observe the installation instructions for
devices in explosive areas; for Europe the European operator directive 99/92/EC
(ATEX137) and the ATEX Product Directive 94/9/EC (ATEX 95), implemented in Germany
by the new health and safety legislation!
• Observe the relevant standards e.g. DIN EN 60079, DIN EN 60079-11, DIN VDE and/or
0118 “Erecting electrical equipment in explosion-threatened areas” DIN EN 60079-14!
• Note all national directives which apply to the installation when installing outside
Germany.
• Intrinsically safe installations must be checked by persons with “recognised
qualifications“.
• Do not connect mains power supply to the external terminal (11).
• The internally used fusible link has a breaking capacity of 1,500A. If the short-circuit
current in the supply network ma be larger than 1,500A, the pump is to be protected
with a suitable back-up fuse with a higher breaking capacity (rated current smaller
than 1,500A).

Filling liquid endliquid end with vent valve and bypass:
Rough venting
왘 Connect intake and delivery line to liquid end.
왘 Connect bypass line.
왘 Open vent valve (5) by one turn of the star knob in counterclockwise direction; the routes
for rough venting via the bypass (6) is now clear.
왘 Switch on pump with power switch (13) and operate at max. stroke length and stroke rate
until liquid end is filled completely and free of bubbles (when the medium is visible in the
venting or metering line).
왘 Close vent valve.
왘 Switch off pump with power switch (13).
The pump is now ready for operation
Setting fine ventmetering gas-emitting media:
NOTE
•A part of the metered quantity is constantly routed back into the supply tank.
The return quantity should be approx. 20 % of the metered quantity.
• The media must be low-viscous (thin-bodied) and without solids.
• If the return flow line ends above the liquid level, the precision vent valve acts as a
vacuum breaker and prevents discharge of the supply tank if a vacuum builds up in
the metering line.
• Retighten the screws in the liquid end after 24 hours of operation.
Operation
왘 Remove star knob from vent valve (5).
왘 Using a screwdriver, turn screw in vent valve approx. 1 turn in counterclockwise direction.
왘 Fit star knob on vent valve (5).
Venting liquid endHV version:
Initial intake and venting is impaired to a certain extent by the valves and valve springs which
are still dry. Therefore select the shortest possible intake head or vent the liquid end with inlet
or admission pressure on the intake side.
If not successful, shortly operate pump without valve spring in the pressure valve:
왘 Unscrew delivery connection and press away ball from O-ring.
왘 Fill liquid end with water or suitable liquid.
왘 Fit delivery connection without valve spring.
왘 Fit short piece of PVC hose (100 mm) on to hose socket, half fill with water.
왘 Operate pump at max. stroke length until metering is visible in the hose.
왘 Re-install valve spring – avoid twisting by fitting an approx. 4 mm Ø drift through the
pressure valve in order to hold the spring in the centre position.
왘 Reconnect delivery line.
Venting liquid endwhen pump delivers in a pressure system and has drawn in air:
왘 Set venting on delivery side: Release metering line or open vent valve.
왘 Switch on pump and vent at stroke length 100 %.

6.2Determining the Delivery Capacity
The actual delivery capacity is dependent on the stroke length, stroke frequency (rate) and
backpressure in the metering line. The relationship between capacity/stroke length/stroke
frequency (rate) is illustrated in the nomogram for each type of pump. A correction factor can
be read off from the diagram which shows the change in capacity referred to backpressure.
The measurements for determining the nomograms were conducted with water and the
correction factor was determined at a stroke length of 70 %. The capacity scatter over all
material versions is -5 % (for max. value: not specified).

Page 27
Page 28
Operating
왘 Select the required capacity within the value range of the pump type (see capacity data).
왘 Select the nomogram and diagram of the pump type.
왘 Mark the backpressure in the metering system on the abscissa and read off the
corresponding correction factor on the ordinate.
왘 Divide the required capacity by the correction factor.
왘 Using a ruler, mark the determined capacity on the middle scale of the nomogram.
왘 Draw a line across all three scales – as horizontal as possible, however, such that the line
intersects at least one of the two outer scales; where possible, select a graduation with a
large value on the stroke length scale.
The point of intersection of the line with the right-hand scale shows the stroke frequency (rate)
to be set, the point of intersection of the line with the left-hand scale shows the stroke length to
be set.
Capacity with mean backpressure:11.9 l/h (see capacity data)
Required capacity:6 l/h
Backpressure:8 bar
→Correction factor as per diagram:0.9
→Capacity to be set:6 l/h
0.9
= 6,66 l/h
→Stroke length as per nomogram:80 %
→Stroke rate as per nomogram:80 stroke/min
NOTE
• Select large stroke length and low stroke rate for highly viscous and gas-emitting
media.
• Use self-venting liquid end for gas-emitting media with viscosity ≤ 20 mPa s.
• Select a shorter stroke length and high stroke rate for effective mixing.
• For a precise dosing, choose metering-stroke of not less than 30 %.
At max. pressure stroke length
≥ 60 % for type 1601,
≥ 40 % for type 1201 and 1002,
≥ 20 % for type 0803;
the stroke length can be reduced further at lower pressure.
• Set the stroke length greater for pumps with the precision vent open
