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 optimally suited to
the transport of liquid chemicals.
The Duodos double diaphragm pump transports liquids to a dis‐
charge lift of 70 m. As the pump capacity depends greatly on the
back pressure, the performance curve must always be observed.
At the same time, the differential pressure between the hydraulic
and pneumatic sides must not exceed 2 bar. Higher values reduce
the service life of the double diaphragm pump.
When selecting the double diaphragm pump you must check its
material compatibility. In addition, the density, viscosity, solids con‐
tent and temperature of the liquid being transported must be con‐
sidered.
Permissible values for the medium
Temperature of the medium
– PP version: 5 ... 65 °C
– PVDF version: -13 ... 93 °C
Viscosity of the medium max. 200 mPas
Solids content: none

uation.
2.2 Users' qualifications
WARNING!
Danger of injury with inadequately qualified personnel!
The operator of the plant / device is responsible for
ensuring that the qualifications are fulfilled.
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 con‐
ducted by qualified personnel.
– Unqualified personnel should be kept away from
the hazard zone
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/her 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 ProMinent or another authorised distribution partner.
Trained qualified per‐
sonnel
A 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/her
training, knowledge and experience, as well as knowledge of pertinent regula‐
tions. The assessment of a person's technical training can also be based on
several years of work in the relevant field.
Electrician Electricians are deemed to be people, who are able to complete work on elec‐
trical systems and recognize and avoid possible hazards independently based
on his/her technical training and experience, as well as knowledge of pertinent
standards and regulations.
Electricians should be specifically trained for the working environment in
which the are employed and know the relevant standards and regulations.
Electricians must comply with the provisions of the applicable statutory direc‐
tives on accident prevention.
Customer Service depart‐
ment
Customer Service department refers to service technicians, who have
received proven training and have been authorised by ProMinent to work on
the system.
Safety and Responsibility

Note for the system operator
The pertinent accident prevention regulations, as well
as all other generally acknowledged safety regulations,
must be adhered to!
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 gas‐
eous or solid media
– Only use the pump in accordance with the tech‐
nical data and specifications outlined in the oper‐
ating instructions.
– The pump is not designed for use in areas at risk
from explosion
– Only switch the device on if it has been properly
fastened to the ground or its holding fixture.
2.4 Duodos general safety notes
WARNING!
Danger from hazardous substances!
Possible consequence: Fatal or very serious injuries.
Please ensure when handling hazardous substances
that you have read the latest safety data sheets pro‐
vided by the manufacture of the hazardous substance.
The actions required are described in the safety data
sheet. Check the safety data sheet regularly and
replace, if necessary, as the hazard potential of a sub‐
stance 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 associ‐
ated hazard assessment for the workstations affected.

WARNING!
Hazardous media / contamination of persons and
equipment
Possible consequence: Fatal or very serious injuries.
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 con‐
veyed are always decisive for initiating counter
measures in the event of leakage to the media
being conveyed
– Observe the general restrictions in relation to vis‐
cosity limits, chemical resistance and density
WARNING!
Service life of the diaphragm
Possible consequence: Fatal or very serious injuries
The service life of the diaphragm cannot be precisely
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 defec‐
tive 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 dia‐
phragm pump.
Before undertaking any maintenance and repair work,
close off the compressed air supply, discharge 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 maximum
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 implementation of suitable meas‐
ures depends on the local circumstances 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.
