3 Safety instructions
When operating the pump, the safety instructions
contained in this manual, the relevant national acci-
dent 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 en-
vironment and the machine and results in a loss of
any right to claim damages.
For example, non-compliance may involve the fol-
lowing 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 in-
stalling or removing the pump exists. Proper and se-
cured 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 per-
sonnel
The personnel responsible for operation, mainte-
nance, inspection and assemblymust 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 under-
stood by the personnel.
3.5 Safety instructions relevant for operation
•If hot or cold machine components involve haz-
ards, they must be guarded against accidental
contact.
•Guards for moving parts (e.g. coupling) must not
be removed from the machine while in operation.
•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 persons
or the environment. Statutory regulations are to
be complied with.
•Hazards resulting from electricity are to be pre-
vented (see for example, the VDE Specifications
and the bye-laws of the local power supply utili-
ties).
•The pumps’ stability against falling over is not en-
sured unless it is properly mounted onto the tank.
•The female threads on the motor MUST NOT be
used to lift the entire pump and motor assembly.
3.6 Safety instructions relevant for mainte-
nance, 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 fa-
cilities 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.
3.8 Unauthorized alterations and production
of spare parts
Any modification may be made to the machine only
after consultation with the manufacturer. Using
spare parts and accessories authorized by the man-
ufacturer is in the interest of safety. Use of other
parts may exempt the manufacturer from any liabil-
ity.
4 Transport and storage
Protect the pump against damage when transport-
ing.
The pumps may only be transported in a horizontal
position and hooks or straps must be attached on the
motor and pump end.
Do not use the pump shaft for connecting any trans-
portation aids such as hooks or straps.
Pumps must be drained prior to their storage.
Store pump in dry and protected areas and protect it
against penetration of foreign bodies.
Always store pump above the freezing point!
