Issue
05/2003
Safety instructions attached directly to the pump resp.
unit must be followed under any circumstances.
Further they must be kept in good readable condition.
In the same way, as these Operating Instructions
of the pump, all possibly attached Operating
Instructions of accessories (e.g. motor) must be
noticed and kept available.
2.2 Dangers of non-observance of the
Safety Instructions
Non-observance of the Safety Instructions can
lead to loss of any claim for damages.
Further, non-observance can lead to following risks:
Failure of important functions of the machine or
facility.
Failure of electronic appliances and measuring
instruments by magnetic fields.
Endangering of persons and their personal
property by magnetic fields.
Endangering of persons by electric, mechanic and
chemical influences.
Endangering of environment through leakage of
dangerous substances.
On application of the unit in areas endangered
to explosion special attention must be paid to
sections marked with Ex.
2.3 Safety Instructions for the Operator /
Worker
Depending on the operating conditions, wear and
tear, corrosion or age will limit the working life of
the
pump/pump
unit,
and
its
specified
characteristics. The operator must ensure that
regular inspection and maintenance are carried
out so that all parts are replaced in good time,
which would otherwise endanger the safe
operation of the system. If abnormal operation or
any damage are observed, the pump must cease
operation immediately.
If the breakdown or failure of any system or unit
could lead to people being hurt or property being
damaged, such system or unit must be provided
with alarm devices and/or spare modules, and
they should be tested regularly to ensure that they
function properly.
If there is any risk of injury from hot or cold
machine parts, these parts must be protected
against contact by the user, or suitable warning
signs must be affixed.
Contact protection on moving parts (e.g. coupling
guards) must not be removed from systems that
are in operation.
If the sound level of a pump or pump unit is above
85 dB(A) an ear protection has to be used when
staying near the pump for some time.
If dangerous media (e.g. explosive, toxic, hot) leak
out (e.g. from shaft seals), these must be directed
away so that there is no danger to people or the
environment. The provisions of the law must be
observed.
Measures should be taken to exclude any danger
from electricity (e.g. by complying with the local
regulations on electrical equipment). If work is
carried out on live electrical components, they
should be unplugged from the mains or the main
switch turned off and fuse unscrewed. A motor
protection switch is to be provided.
2.4 Safety Instructions for Maintenance,
Inspections and Mounting Work
The operator is responsible that any maintenance,
inspections and mounting work is made by
authorized competent personnel, which must be
informed by havingng read the Operating
Instructions.
Basically, all work on the pump or pump unit
should only be carried out when the pump is
stationary and not under pressure. All parts must
be allowed to return to ambient temperature.
Make sure that no-one can start the motor during
such work. It is essential that the procedure for
stopping the system described in the Operating
Instructions is observed. Pumps or pump systems
that carry media that are dangerous to health must
be decontaminated before being taken apart.
Safety Data Sheets for the various liquids handled.
Immediately after finishing work, all safety and
protective devices must be replaced or restarted.
2.5 Unauthorized Alteration and Spare
Parts Production
Alteration or changes of the machine are permitted
after agreement with the manufacturer.
Original spare parts and accessory authorized by the
manufacturer are serving the safety.
The use of other parts can lead to loss of liability for
therefrom resulting consequences.
2.6 Undue Operation
The operating safety of the delivered machine can
only be guaranteed by designated use acc. to the
following chapters of the Operating Instructions. The
limits stated in the data sheet and / or order
confirmation must not be exceeded under any
circumstances.
2.7 Explosion Protection
On application of units in areas endangered to
explosion measures and references in the chapters
2.7.1 to 2.7.6 must be observed, so that explosion
protection is guaranteed.
2.7.1 Filling of unit
During operation of the pump the system of the
suction and pressure pipe and the pump itself
must permanently be filled with the pumped
liquid. Thus, no explosive atmosphere can
develop and the danger of dry-run is avoided.
