1. GENERAL
1.1 Foreword
The staff employed on installation, operation,
inspection and maintenance must be able
to prove that they know about the relevant
accident prevention regulations and that they
are suitably qualified for this work. If staff do not have
the relevant knowledge, they should be provided with
suitable instruction.
The operating safety of the pumps or units (i.e. pump
plus motor) supplied is only guaranteed if these are used
in accordance with the provisions in “Installation and
Operation”.
The operator is responsible for following the instructions
and complying with the safety requirements given in
these Operating Instructions.
Smooth operation of the pump or pump unit can only be
achieved if installation and maintenance are carried out
carefully in accordance with the rules generally applied in
the fields of engineering and electrical engineering.
If not all the information can be found in these Operating
Instructions, please contact us.
The manufacturer takes no responsibility for the pump or
pump unit if the Operating Instructions are not followed.
These Operating Instructions should be kept in a safe
place for future use.
If this pump or pump unit is handed on to any third
party, it is essential that these Operating Instructions and
the operating conditions and working limits given in the
Confirmation of Order are also passed on in full.
These Operating Instructions do not take into account
all design details and variants nor all the possible chance
occurrences and events which might happen during
installation, operation and maintenance.
Alterations or changes to the machine are only permitted
by agreement with the manufacturer. Original spare parts
and accessories authorized by the manufacturer should be
used for greater safety. We bear no responsibility for the
consequences of using other parts.
We retain all copyright in these Operating Instructions;
they are intended only for personal use by the owner of
the pump or the pump unit. The Operating Instructions
contain technical instructions and drawings which may
not, as a whole or in part, be reproduced, distributed or
used in any unauthorized way for competitive purposes
or passed on to others.
1.2 Guarantee
The guarantee is given in accordance with our
Conditions of Delivery and/or the confirmation of order.
Repair work during the guarantee period may only be
carried out by our authorized distributor. Otherwise the
guarantee ceases to apply.
The guarantee shall not cover natural wear and tear and
all parts subject to wear, such as impellers, shaft sealings,
shafts, shaft sleeves, bearings, wear rings etc., or damage
caused by transport or improper handling.
In order for the guarantee to apply, it is essential that
the pump or pump unit is used in accordance with
the operating conditions given on the type plate,
confirmation of order and in the Data Sheet. This applies
particularly for the endurance of the materials and
smooth running of the pump and shaft sealing.
If one or more aspects of the actual operating conditions
are different, we should be asked to confirm in writing
that the pump is suitable.
1.3 Safety Regulations
These Operating Instructions contain important
instructions which must be followed when the pump
is assembled and commissioned and during operating
and maintenance. For this reason, these Operating
Instructions must be read by the skilled staff responsible
and/or by the operator of the plant before it is installed
and commissioned, and they must be left permanently
ready to hand at the place where the pump or pump unit
is in use. The operator must ensure that the contents
of the Operating Instructions are fully understood by
the staff. The operator must confirm this by signing the
“Plant Manager List” (see Point 10). These Operating
Instructions do not refer to the General Regulations on
Accident Prevention or local safety and/or operating
regulations. The operator is responsible for complying
with these (if necessary by calling in additional
installation staff).
The safety instructions contained in these Operating
Instructions have the following special safety markings.
Warning against personal accidents which
could occur if the safety instructions given in
this part of the Operating Instructions are not
followed.

1.4 Safety Instructions
Dangers of not following safety instructions
Failure to follow the safety instructions can result in the
following, for example:
• People being at risk because of electrical, mechanical
and chemical factors.
• Important functions of the pump or pump unit failing.
• Dangers to the environment.
Safety instruction for the operator
• 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
