1.1 Summary of additional safety instructions for the EX version
of the pump (in accordance with ATEX)
WARNING
In explosion-threatened workplaces in zone 1, device category II 2G of explosion group II C
the pump may not be operated without the corresponding rating plate (and the corre-
sponding EC conformity declaration) for pumps for explosion-threatened workplaces in
accordance with guideline 94/9/EC of the European guidelines.
•From July 1st, 2003 on, only pumps with the corresponding marking according to EC-Ex-
directive 94/9 may be used in industrial premises with potentially explosive atmospheres.
The explosion group, category and type of protection shown on the marking must
correspond to or exceed the conditions prevailing in the intended area of application.
All other uses or modifications are prohibited!
Pumps may never be operated in explosion-threatened workplaces without a correspond-
ing rating plate (and the corresponding EC conformity declaration) for pumps for
explosion-threatened workplaces.

Notes on safety of ProMinent
®
metering pumps
Installations in potentially explosive atmospheres must be inspected by an “accredited
qualified” person. This applies in particular also for intrinsically safe electrical circuits.
Drive motors must be secured by an appropriate motor protection switch. A motor
protection approved for this application must be used for Ex“e”-motors. (Protection
against heating due to overload)
Observe all relevant standards e.g. DIN EN 60079, DIN EN 50020, DIN VDE 0165 and/or
DIN VDE 0118 “Installing electrical equipment in explosion-threatened areas”!
When installing the metering pump, observe the directives for the installation of devices
in explosion-threatened areas, e.g. for Europe the European operator’s guideline 99/92/EC
(ATEX137)*, (in Germany implemented via the new operating safety ordinance (Official
Federal Gazette for 2002, Part 1, No. 70, issued in Bonn 2.10.2002))!
* previously ElexV
Observe documents supplied with individual electric components!
On principle, metering pumps in potentially explosive atmospheres must be equipped
with a safety overflow valve at the outlet side of the pump (serves as protection against
overheating due to overload and against sparks produced by shock due to overload
which has led to the breakage drive parts.)
When using with flammable media:
- Diaphragm pumps with mechanically actuated diaphragm: no additional measures
necessary, however, version with diaphragm rupture indicator, version Ex“i”*, must be
used on principle.
- For all metering pumps for metering inflammable media applies: starting up and
emptying only supervised by a competent person.
- Inflammable media may only be lifted with stainless steel liquid ends. - For exceptional
cases, where this is not possible, also PTFE with carbon may be used, our versions TT_
are made of conductive plastics. In this case, special attention must be paid by the
user due to the lower mechanical stability.
If using the metering pump for Europe e.g. the European operator’s guideline 99/92/EC*
(ATEX 137**), (in Germany implemented via the new operating safety ordinance (Official
Federal Gazette for 2002, Part 1, No. 70, issued in Bonn 2.10.2002) and the German
dangerous chemicals ordinance))!
* previously Ex Vo, Vb F
** previously ATEX118A
Observe also all relevant standards e.g. DIN EN 60079-10/14 and DIN EN 50020 for
installations in explosion-threatened areas!
Note all national directives which apply to the installation!
•Wear parts (diaphragms, bearings etc.) of metering pumps used in potentially explosive
atmospheres must be replaced after having completed 90% of their nominal product life.
The lubricant supply must be regularly checked for lubricated pumps, for instance by
checking the fill level, visual inspection for leakages etc.
The proper general function, in particular of the drive, must be safeguarded by regular
inspections (leakages, noises, temperatures, possible discoloration due to excess
temperatures....).
Use original spare parts should exchange become necessary!
Check that the pressure relief valve downstream from the pump is functioning correctly!
The pressure relief valve must prevent the gearbox from being overloaded and over-
heating in explosion-threatened workplaces!
When cleaning plastic parts, attention must be paid to not generating any electrostatic
charge by rubbing excessively. - see danger sign.
These measures are the minimum protection measures specified by ProMinent. Should
the user know about any further risks, it is his duty to eliminate them by taking
corresponding measures.

Safety devices
The following safety notice must be affixed to the pump (with PP, PC and PV liquid ends, acrylic
glass cover, ...)
Because of danger of electrostatical
ignition use damp cloth only
for wiping plastic parts!
ATTENTION
EC conformity declaration / certificates
The EC conformity declaration for pumps for explosion-threatened workplaces is supplied with
the pump (the copy of the EC conformity declaration for the pump itself does not apply to pumps
designed for explosion-threatened workplaces).
The EC conformity declarations, the EC series prototype test reports and the operating manuals
for the individual components are also supplied with the pump.
1.2 General notes
WARNING
The equipment/devices may only be used for their intended purpose.
•ProMinent
®
metering pumps must not be assembled with parts which are not tested and
recommended by ProMinent otherwise this can lead to injury to persons and damage to
property for which no liability will be accepted!
Pumps must be accessible at all times to facilitate operation and maintenance. Access
points must not be obstructed or blocked!
Before carrying out any maintenance and repair work always drain off and flush out the
liquid end first if hazardous or unknown metered media are used!
When metering hazardous or unknown liquids, always wear safety clothing (safety
goggles, gloves, ...) when working on the liquid end!
•You must observe the guidelines in this operating instructions manual and the ”General
operating instructions manual for ProMinent
®
motor-driven metering pumps and hydraulic
accessoires” on assembly, installation and maintenance!
1.3 Notes on installation, start-up and operation
WARNING
The metering pump can contain water residue in the liquid end as the result of testing at
the factory!
If handling media which must not come in contact with water, all traces of water must be
removed from the liquid end before start-up! For this purpose, turn the pump through
180˚ and drain off the liquid end then flush with a suitable medium from above via the
intake connection!
Do not connect mains voltage to the control cable!
When operating the metering pump against a closed shut-off element on the pressure
side or in the event of pressure peaks during the metering stroke, the system pressure
can reach a multiple of the maximum permissible operating pressure that can conse-
quently cause the pressure line to burst!
•To avoid this situation, an overflow is recommended for the purpose of limiting the
maximum permissible operating pressure of the pump or system.
Do not connect a metal bypass line to the overflow valve on the PVT delivery unit! This
could cause cracks in the delivery unit!

IMPORTANT
Set stroke length only with pump in operation!
Pull the red plug for venting the gear unit during initial operation of the Sigma/ 2 metering
pump (refer to Fig. 2, item 10)!
NOTE
The pump must be secured in such a way that no vibrations can occur! The valves of the
liquid end must always be positioned vertically in order to ensure trouble-free operation!
The intake and delivery lines must always be arranged such as to ensure connection at
the liquid end is free of mechanical stress!
The lines must be secured such that no vibrations can occur!
Only use the clamping rings and hose sockets intended for the relevant hose diameter as
well as original hoses with the specified hose dimensions and wall thickness otherwise
the stability and durability of the connection will not be guaranteed!
Avoid reducing hose sizes!
Observe the permissible pressure of the hoses!
•A vent with return to the supply tank is advisable when metering extremely aggressive or
hazardous media!
In addition, a shut-off valve should be provided on the delivery or intake side!
1.4 Notes on maintenance and repair
WARNING
Only specially trained and authorized persons are permitted to carry out maintenance on
metering pumps and their peripherals!
If hazardous or unknown metering media are used, always flush out the liquid end first
before carrying out any maintenance and repair work!

Sigma/ 2 diaphragm-type metering pump is an oscillatory displacement pump
with the stroke length adjustable in steps of 0.5 %. It is driven by electric motor (1). The rotary
drive of the electric motor is stepped down by worm gear and transmitted via the eccentric roller
(3) to the push rod (4) connected to fork (8) and converted into oscillatory movement. Return
spring (5) presses the fork with push rod positively against the eccentric roller thus producing the
return stroke. The stroke is adjusted by means of stroke adjustment knob (6) and spindle (7) by
limiting the return stroke. Stroke movement is transmitted directly to the displacement diaphragm.
Interacting with the valves, this diaphragm produces the overpressure and vacuum in the liquid
end necessary for delivery. Flow is pulsating.
In the basic type, the electric motor is normally a 3-ph extended-range AC motor (refer to Section 3
for other options).

2.2.4 Functional description, delivery unit
The heart of the delivery unit is the DEVELOPAN
®
metering diaphragm (2). It hermetically seals
the delivery chamber of the liquid end (4) and produces a displacement in the liquid end. The end
disc (5) made of chemically resistant plastic together with safety diaphragm (13) separates the
drive housing from the delivery unit and protects the drive from corrosion in the event of the
diaphragm failing. Delivery is based on the interaction between intake valve (1) and head valve (3)
of the same design together with the diaphragm movement. The valve balls can be supported
with springs for metering viscous media.
The connection dimensions of valves and liquid ends of the same size but with different materials
are identical. These parts can be interchanged as required.
Materials and dimensions are specified in Section 3, Technical data.

2.2.5 Integrated overflow valve with bleeder function
Task:
The task of the overflow valve is to protect the motor and gear unit against impermissible
overpressure caused by the metering pump.
This function is produced by a spring-loaded ball.
A pressure relief mechanism for the bleeder function is provided.
Design and functional description
(refer to Fig. No. 6 and 7)
Initially, the overflow valve illustrated under item 102 operates as a simple directly controlled
safety valve. As soon as the pressure set with spring item 132 is exceeded, the effective pressure
raises ball item 130. The liquid then flows off into the tank via hose connection item 128.
