3 Safety instructions
When operating the pump, the safety instructions
contained in this manual, the relevant national
accident prevention regulations and any other
service and safety instructions issued by the plant
operator are to be observed.
3.1 Hazards in the event of non-compliance
with the safety instructions
Non-compliance with the safety instructions may
produce a risk to the personnel as well as to the
environment and the machine and results in a loss
of any right to claim damages.
For example
, non-
compliance may involve the following hazards:
Failure of important functions of the ma-
chines/plant
Failure of specified procedures of maintenance
and repair
Exposure of people to electrical, mechanical and
chemical hazards
Endangering the environment due to hazardous
substances being released
3.2 Unauthorized modes of operation
Pump may not be used in potentially explosive
environments!
Pump and discharge piping are not designed to
hold any weight and may not be used as a step
ladder.
3.3 Remaining Risk
Risk of Injury!
Risk of squeezing or crushing body parts when
installing or removing the pump exists. Proper and
secured lifting tools must be used.
Risk of burns!
The pump must have cooled down sufficiently prior
to commencing any repair, maintenance or installa-
tion.
3.4 Qualification and training of operating
personnel
The personnel responsible for operation, mainten-
ance, inspection and assembly must be adequately
qualified. Scope of responsibility and supervision of
the personnel must be exactly defined by the plant
operator. If the staff does not have the necessary
knowledge, they must be trained and instructed,
which may be performed by the machine manufac-
turer or supplier on behalf of the plant operator.
Moreover, the plant operator is to make sure that
the contents of the operating manual are fully
understood by the personnel.
3.5 Safety instructions relevant for operation
If hot or cold machine components involve
hazards, they must be guarded against acciden-
tal contact.
Guards for moving parts (e.g. coupling) must not
be removed from the machine while in opera-
tion.
Never subsequently alter any safety devices
(e.g. pressure relief valves)!
It is necessary to ensure that all safety devices
always work properly!
Any leakage of hazardous (e.g. explosive, toxic,
hot) fluids (e.g. from the shaft seal) must be
drained away so as to prevent any risk to per-
sons or the environment. Statutory regulations
are to be complied with.
Hazards resulting from electricity are to be
prevented (see for example, the VDE Specifica-
tions and the bye-laws of the local power supply
utilities).
The pumps’ stability against falling over is not
ensured unless it is properly mounted onto the
tank or to the floor.
The female threads on the motor MUST NOT be
used to lift the entire pump and motor assembly.
3.6 Safety instructions relevant for mainten-
ance, inspection and assembly work
Any work on the machine shall only be performed
when it is at a standstill, it being imperative that the
procedure for shutting down the machine described
in this manual be followed.
Pumps and pump units which convey hazardous
media must be decontaminated.
On completion of work all safety and protective
facilities must be re-installed and made operative
again.
Prior to restarting the machine, the instructions
listed under “Start up” are to be observed.
3.7 Signs on the pump
It is imperative that signs affixed to the machine,
e.g.
arrow indicating the direction of rotation
symbols indicating fluid connections
be observed and kept legible.
