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.

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.

Safety and Responsibility

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.
