Fig. 1: Sigma with hygienic pump head
Information on the pump:
nThe pump is a diaphragm pump.
nThe pump is intended to meter liquid food products or additives
in closed food processes.
nThe materials and components intended to come into contact
with food products comply with the “Hygienic Design” and Reg‐
ulation (EC) No 1935/2004.
Take into account the resistance of the wetted materials and the
ProMinent Resistance List when selecting the feed chemical - see

2 Safety chapter
2.1 User qualification
WARNING!
Danger of injury with inadequately qualified per‐
sonnel
The operator of the system / equipment is respon‐
sible for ensuring that the qualifications are ful‐
filled.
If inadequately qualified personnel work on the unit
or loiter in the hazard zone of the unit, this could
result in dangers that could cause serious injuries
and material damage.
– All work on the unit should therefore only be
conducted by qualified personnel.
–Unqualified personnel should be kept away
from the hazard zone.
The pertinent accident prevention regulations, as
well as all other generally acknowledged safety
regulations, must be adhered to.
Training Definition
Instructed personnel An instructed person is deemed to be a person who has been instructed and,
if required, trained in the tasks assigned to him and possible dangers that
could result from improper behaviour, as well as having been instructed in the
required protective equipment and protective measures.
Trained user A trained user is a person who fulfils the requirements made of an instructed
person and who has also received additional training specific to the system
from the manufacturer or another authorised distribution partner.
Trained, qualified per‐
sonnel
A trained, qualified employee is deemed to be a person who is able to assess
the tasks assigned to him and recognize possible hazards based on his
training, knowledge and experience, as well as knowledge of pertinent regula‐
tions. A trained, qualified employee must be able to perform the tasks
assigned to him independently with the assistance of drawing documentation
and parts lists. The assessment of a person's technical training can also be
based on several years of work in the relevant field.
Electrical technician An electrical technician is able to complete work on electrical systems and rec‐
ognise and avoid possible dangers independently based on his technical
training and experience as well as knowledge of pertinent standards and regu‐
lations. An electrical technician must be able to perform the tasks assigned to
him independently with the assistance of drawing documentation, parts lists,
terminal and circuit diagrams. The electrical technician must be specifically
trained for the working environment in which the electrical technician is
employed and be conversant with the relevant standards and regulations.
Service The Service department refers to service technicians, who have received
proven training and have been authorised by the manufacturer to work on the
system.

2.2 Intended use
Intended use:
nThe pump is intended to meter liquid food products or additives
in closed food processes.
nThe pump can meter the following types of liquid food products
or additives:
–Liquid food products or additives with a viscosity of up to
30,000 mPas
– Liquid food products or additives with a temperature of - 10
°C ... 90 °C
– Liquid food products or additives with a pH value of 2 ... 13
pH
– Liquid food products or additives containing solids of < 0.3
mm
– Liquid food products or additives which do not crystallise.
We can provide you with an approval for all values outside of these
specifications providing this is possible after testing.
2.3 Reasonably predictable misuse
Any other application or any application beyond the use specified
in
Ä Chapter 2.2 ‘Intended use’ on page 6 is not deemed to be cor‐
rect and proper, especially the aseptic pumping of liquid food prod‐
ucts or additives. The pump meets the requirements of hygienic
processes, but not the requirements of aseptic processes.
2.4 Safety information
O-rings DIN 11864 R:
nIndividual particles may be released when exposed to high
thermal load. In the event of high thermal loads, shorten the
maintenance intervals to rule out this release.
nOnly suitable O-rings may be used for the flange connections.
Only use materials that have been proved to be suitable for
correct and proper use and meet the requirements for contact
with food products in accordance with EC Regulation no.
1935/2004.
Flushing liquid:
nMetering pumps with hygiene pump head are fitted with tightly
closing ball check valves, which is why flushing liquid collects
above the valves after the CIP (cleaning in place) stage.
Always use appropriate processes to remove this flushing
liquid.
Extreme temperatures:
nLiquid media, ambient temperatures, and heating or cooling
equipment can cause extreme temperatures at the liquid end.
nIf necessary, take appropriate measures to combat this.
Rupture of the diaphragm
nIn the event of a diaphragm rupture warning being triggered,
securely initiate the replacement of the diaphragm as quickly
as possible.
nStop metering if this is required for your process.

2.5 Cross-contamination
Cross-contamination generally refers to the direct or indirect
unwanted transfer of contamination to an object. When replacing
your feed chemical or pump components etc., make sure that there
is no, or could be no, hygienic risk to the process. If in doubt, clean
the pump,
Ä Chapter 8 ‘Notes on cleaning metering pumps with
hygienic pump head’ on page 14 .
2.6 Sound pressure level
The sound pressure level of the dosing heads with the pump run‐
ning is < 80 dB (A) (ISO 11688-1 (11/2009)).

3 Storage and transport
Store and transport the pump in such a way that its hygienic prop‐
erties are not impaired by the entrainment of feed chemicals, dirt
etc. In addition, refer to Regulation (EC) no. 852/2004 governing
food hygiene.
nThe Sigma 2 and Sigma 3 are very top-heavy.
nUse lifting straps to move the large dosing head of the Sigma 3
(070410, 070580, 040830, 041030). Weight: approx. 32 kg
