health and the safety of workers that could be at
risk from an explosive atmosphere.
This unit must not be operated above
the values specified in the data sheet
with regard to the pumped liquid, flow
rate, speed, density, discharge head
and working temperature as well as
motor power.
Comply with the directions contained in the
operating
instructions
or
contract
documentation; if necessary consult the
manufacturer.
All important characteristics are documented in
the data sheet included in the scope of delivery.
In case of operating conditions other than those
described in the data sheet, check the following
again:
♦
Pump design
♦
Accessories’ design
♦
Resistance of the materials.
2.2 Safety instructions for
operating company/operator
The following must be observed:
♦
The safety instructions contained in these op-
erating instructions
♦
The existing regulations for the prevention of
accidents
♦
This includes internal working, operating and
safety regulations of the operating company.
♦
Hot or cold machine parts on site must be
safeguarded against contact.
♦
Do not remove any protective devices when the
machine is in operation.
♦
Hazards due to electrical energy must be ex-
cluded.
♦
Leakages of hazardous media (e.g. explosive,
toxic, hot) must be discharged in a way that
ensures no hazards to persons or the
environment. Legal regulations must be
observed.
Attention when using the units in
potentially explosive atmospheres!
Prevent inadmissible modes of operation.
2.3 Safety instructions for
maintenance
Only perform work on the unit when it is
stationary.
It is essential to observe the shutdown of the unit
described in the operating instructions. See
section 6.3
.
Pumps that convey media harmful to health must
be decontaminated.
All safety and protective facilities are to be
reinstalled and made functional immediately on
completion of work.
When the safety instructions are observed
(see also
sections 5.1 and 7.5.2
), the magnetic
couplings pose no hazard and do not affect the
environment.
During disassembly and assembly
and during transport and storage of
magnetic couplings as individual
parts, it is essential to observe the
safety instructions in
section 7.5.2
.
Before resuming operation, observe the points
listed in
section 6.1
.
2.4 Unauthorized modification and
production of spare parts
Modification or alterations to the machine are only
permitted after consultation with the manufacturer.
Original spare parts and accessories approved by
the manufacturer serve to ensure safety.
The consequences of using other parts may
negate the manufacturer’s liability as a result.
2.5 Prohibited operating modes
The operational reliability of the machine supplied
is only guaranteed if it is used as intended in ac-
cordance with
section 2.1
of the operating in-
structions.
Do not exceed the limits specified in the data
sheet under any circumstances.
2.6 Special conditions for
explosion protection
When using the units in potentially explosive
atmospheres, the measures and instructions in
sections 2.6.1 to 2.6.9
must be observed to
ensure explosion protection.
2.6.1 Filling the unit
During pump operation, the interior of
the pump that comes into contact with
the liquid must be filled with pumped
liquid at all times.
This ensures that there is no explosive atmos-
phere and the risk of running dry is prevented.
If the operator cannot ensure this, we
recommend
that
appropriate
monitoring measures be provided.
All auxiliary, heating and cooling
systems must also be carefully filled.
