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.
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 is 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 having 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 the 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
there from 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 Use acc. to Regulations
2.7.1 Speed, Pressure, Temperature
Suitable safety measures must be taken at the
plant to ensure that the speed, pressure and
temperature of the pump and the shaft sealing
do not exceed the limit values given in the data
sheet and / or order confirmation. The given
admission pressures (system pressures) must
also be sufficiently high.
Further, pressure shocks, as can occur on too fast
shut down of the facility, must be kept away from the
pump (e.g. by non-return valve at pressure side, fly
wheel, air tanks). Quick temperature changes must be
avoided. They could cause a temperature shock and
lead to damage or impair the function of single
components.
