1 Function and identification
1.1 Function
The Duodos is an air-driven double diaphragm pump.
The Duodos is run-dry safe and self-priming.
The pump capacity of the double diaphragm pump can be con‐
trolled by changing the pressure in the air supply. The air control is
designed for oil-free operation. The Duodos is ideally suited for the
transport of liquid chemicals.
The Duodos double diaphragm pump transports liquids up to a
delivery height of 7 m. As the pump capacity depends greatly on
the back pressure, always observe the performance curve.
Check the compatibility of the material when selecting the double
diaphragm pump. Also consider the density, viscosity, solids con‐
tent and temperature of the liquid being pumped.
Permissible values for the medium
Temperature of the medium
– PP version: 10 ... 80 °C
– PVDF version: -13 ... 93 °C
Viscosity of the medium: max. 200 mPas
Solids: < 3 mm

2.2 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.

2.3 Intended use
CAUTION!
Intended use
Possible consequences if the instructions are not
observed: Minor injuries and material damage
– The pump is intended for liquids transport
– The pump is not intended for the transport of
gaseous or solid media
– Only use the pump in accordance with the
technical data and specifications outlined in the
operating instructions.
– The pump is not designed for use in areas at
risk from explosion
– Only switch the device on if it has been prop‐
erly fastened to the ground or its holding fix‐
ture.
2.4 Duodos general safety notes
WARNING!
Danger from hazardous substances!
Possible consequence: Fatal or very serious inju‐
ries.
Please ensure when handling hazardous sub‐
stances that you have read the latest safety data
sheets provided by the manufacture of the haz‐
ardous substance. The actions required are
described in the safety data sheet. Check the
safety data sheet regularly and replace, if neces‐
sary, 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 worksta‐
tions affected.

WARNING!
Hazardous media / contamination of persons and
equipment
Possible consequence: Fatal or very serious inju‐
ries. material damage
– Ensure the device is resistant to the media
being conveyed
– Always observe the safety data sheets for the
media to be conveyed. The system operator
must ensure that these safety data sheets are
available and that they are kept up-to-date
– The safety data sheets for the media being
conveyed are always decisive for initiating
counter measures in the event of leakage to
the media being conveyed
– Observe the general restrictions in relation to
viscosity limits, chemical resistance and den‐
sity
WARNING!
Service life of the diaphragm
Possible consequence: Fatal or very serious inju‐
ries
The service life of the diaphragm cannot be pre‐
cisely specified. For this reason, the possibility of
fracture and subsequent leakage of liquids must be
taken into account.
In addition, you must prevent particles from the
defective diaphragm reaching the media being
conveyed. This can be achieved e.g. by filtration, a
hose rupture alarm or other means suitable for the
respective process.
CAUTION!
Compressed air
Before working on the double diaphragm pump,
close the compressed air lines and vent the double
diaphragm pump.
Before undertaking any maintenance and repair
work, close off the compressed air supply, dis‐
charge the compressed air and detach the air
supply line from the double diaphragm pump. The
line to the discharge side of the double diaphragm
pump may be under pressure and must likewise be
vented.
CAUTION!
Hot surface
When conveying hot liquids, the pump can likewise
become hot. Hot surfaces may then be present on
the pump. Bear this in mind and take suitable
measures to reduce any hazards.
Safety and responsibility

Maximum pump sound pressure level 91 dB
Depending on the operating conditions, the max‐
imum sound pressure level of the device can reach
88 dB ± 3 dB. Bear this in mind and take suitable
measures to reduce any impact caused by this
sound pressure level. The type and implementa‐
tion of suitable measures depends on the local cir‐
cumstances and is the responsibility of the system
operator.
Check the fastening elements are correctly seated.
Before commissioning the double diaphragm
pump, you must check that all fastening elements
with sealing rings are correctly seated. The seals
may ‘creep’ , so that the fastening elements come
loose over time.
In the event of a diaphragm rupture
In the event of a diaphragm rupture, the pumped
medium can enter the air system of the double dia‐
phragm pump and from there into the atmosphere.
If the pumped medium is a dangerous, harmful or
toxic substance, the air outlet must be routed to a
suitable area where safe disposal is possible.
Operation in the open air and outdoors
– Take suitable measures to protect the device
from environmental influences when operating
outside such as:
– UV rays
– Humidity
– Frost, etc.
