1.1. Foreword
This product corresponds with the requirements of the
Machine directive 2006/42/EC.
The staff employed on installation, operation, in-
spection and maintenance must be able to prove
that they know about the relevant accident preven-
tion regulations and that they are suitably qualified
for this work. If the staff does 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 given in the Confirmation
of Order and/or Point
6 in “Installation”
The operator is responsible for following the instructions
and complying with the safety requirements given in these
Operation 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 field of mechanical 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 op-
erating conditions and working limits given in the Confir-
mation 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 oc-
currences and events which might happen during installa-
tion, 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
us, or subject to our written approval. Otherwise the guar-
antee ceases to apply.
Longer-therm guarantees basically only cover correct
handling and use of the specified material. Wear and tear,
parts that are subject to wear such as impellers, mechani-
cal seals or packing, shaft seals, shafts, shaft sleeves,
bearings, split rings and wear rings etc., as well as dam-
age caused during transport or as a result of improper
storage are not covered by the guarantee. 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 in the Data
Sheet. This applies particularly for the endurance of the
materials as well as the smooth running of the pump. If
one or more aspects of the actual operation 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 instruc-
tions which must be followed when the pump is assem-
bled and commissioned and during operating and mainte-
nance.
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 at hand at the place
where the plant is in use. The operator must ensure that
the contents of the Operating Instructions are fully under-
stood by the staff. 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 In-
structions have the following special safety markings as
specified in DIN 4844:
Safety reference!
Non-observance can impair the pump and its func-
tion.
General Symbol for Danger!
Persons can be endangered.
Warning of electric voltage!
It is absolutely essential that safety information affixed di-
rectly to the pump or pump unit is followed and main-
tained so that it is always easily legible.
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, mechan-
ical an chemical factors.
Important functions of the pump of pump unit fail-
ing.
Safety instructions 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 characteris-
tics. The operator must ensure that regular inspec-
tion and maintenance are carried out so that all
parts are replaced in good time which would oth-
erwise endanger the safe operation of the system.
If abnormal operation or any damaged are ob-
served, the pump must cease operation immedi-
ately.
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 func-
tion properly.
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
