1.1Summary 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 corresponding 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 corresponding rating plate (and the corresponding EC conformity declaration) for pumps for explosion-threatened workplaces.

•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 overheating 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.

Notes on safety of ProMinent® metering pumps |
Safety devices
The following safety notice must be affixed to the pump (with PP, PC and PV liquid ends, acrylic glass cover, ...)
ATTENTION
Because of danger of electrostatical ignition use damp cloth only
for wiping plastic parts!
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.
1.2General 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!
1.3Notes 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 consequently 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!
ProMinent® |

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!
1.4Notes 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!
•When metering hazardous or unknown liquids, always wear safety clothing (safety goggles, gloves, ...) when working on the liquid end!
•Always depressurize the delivery line first before carrying out any work on the pump! Always discharge and flush liquid end!
Observe safety data sheets for metered liquid!

2.1Identification of pump type
Fig. 1
The identity code and serial number are given in addition to the standard technical specifications. These two numbers must always be quoted when making any enquiries as they enable distinct identification of the type of metering pump.
2.2Design/Functional description
2.2.1Functional description, drive
The ProMinent® 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).

2.2.4Functional 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.
