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

aging situation.

Safety and responsibility

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.

Safety and responsibility

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.

Safety and responsibility

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.
