2. Safety
This Operation Manual gives basic instructions which are to be observed during installation, operation and
maintenance of the pump. It is therefore imperative that this manual be read by the responsible personnel/operator
prior to assembly and commissioning. It is always to be kept available at the installation site. It is not only the general
safety instructions contained under this main heading `Safety` that are to be observed, but also the specific
information provided under the other main headings.
2.1 Kennzeichnung von Hinweisen in der Betriebsanleitung
Safety instructions given in this manual, non-compliance with which would affect safety,
are identified by the following symbol: or where electrical safety is involved, with
see DIN 4844 - W9 see DIN 4844 - W8
Safety measures which can cause damage to the machine if not adhered to, are marked
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.
2.2 Qualification and Training of Operating Personnel
The personnel responsible for operation, maintenance, 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
manufacturer 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.
2.3 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 may result in a loss of any right to claim damages.
For example, non-compliance may involve the following hazards:
• Failure of important functions of the machine/plant
• Failure of specified procedures of maintenance and repair
• Exposure of people to electrical, mechanical and chemical hazards
• Endangering the environment owing to hazardous substances being released.
2.4 Safety at Work
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.
2.5 Safety Instructions Relevant for Operation
• If hot or cold machine components involve hazards, 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 prevented (see, for example, the VDE Specifications and the by-laws of
the local power supply utilities).
2.6 Safety Instructions Relevant for Maintenance, Inspection and Assembly Work
It shall be the plant operator’s responsibility to ensure that all maintenance, inspection and assembly work is
performed by authorized and qualified personnel who have adequately familiarized themselves with the subject matter
by studying this manual in detail.
Any work on the machine shall only be performed when it is at a standstill.
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 `Operation` are to be observed.
