TM 7345

Edition 10/2008

The instructions contained in the operating
manual or contract documentation must be
observed; if necessary consult the manufacturer.
All important features are documented in the data
sheet included in the scope of delivery.
In the event of operating conditions other than those
described in the data sheet, the following are to be
checked again:

design of the pump
design of the accessories
resistance of the materials.

2.2 For the customer/operator

The following must be observed:

The notes on safety contained in this operating
manual,
the prevailing regulations on accident prevention,
in-house work, operating and safety regulations of
the customer.
Hot or cold machine parts must be protected by
the customer against being touched.
No protective facilities may be removed when the
machine is in operation.
The ring bolt 900/1 must not be removed
or loosened as deposits could form
between the drive magnet assembly and
the lantern. For example, overheating and thus
potential sources of ignition could arise due to
frictional energy.
Hazards due to electricity are to be excluded.
Leaks of hazardous media (e.g. explosive, toxic,
hot) must be removed so that no risk arises for
people and the environment. The statutory
provisions are to be observed.

Caution when using the units in potentially
explosive area! Inadmissible modes of
operation must be prevented.

2.3 For maintenance

In principle, work on the unit may only be performed
when it is at a standstill.
It is imperative to observe the procedure for stopping
the machine described in this operating manual. See
Section 6.3.
Pumps which convey media which are a health
hazard must be decontaminated.
All safety and protective facilities must be remounted
or enabled immediately after the end of work.
In the assemble state, if the safety notes (see also
Section 5.1 and 7.5.2) are observed, the magnetic
drives do not cause any risks or have any affect on
the environment.

During dismantling and assembly as well as
during transport and storage of the magnetic
drives as single components, the notes on

safety in Section 7.5.2 must be observed.
The points listed in Section 6.1 must be followed
before recommissioning.

2.4 Conversion work and

production of spare parts by
the customer

Conversion of or changes to the machine are only
admissible after consultation with the manufacturer.
Original spare parts and accessories authorised by
the manufacturer serve to enhance safety.
The use of other parts may annul the liability for any
resultant consequences.

2.5 Improper operation

The operational safety of the machine supplied is only
guaranteed if it is used properly in accordance with
Section 2.1 of this operating manual.
The operating limits specified in the data sheet must
under no circumstances be exceeded.

2.6 Explosion protection

If the units are used in potentially explosive areas, the
measures and notes in Sections 2.6.1 to 2.6.9 are
imperative to guarantee the explosion protection.

2.6.1 Filling the unit

During pump operation the wetted interior of
the pump must always be filled with the liquid
medium.

This prevents any explosive atmosphere and the risk
of dry-running.

If the customer cannot ensure this, we
recommend that appropriate monitoring
facilities be provided.

All auxiliary, heating and cooling systems
must also be carefully filled.
