supplier to take care of such training. In addition, the operator
is responsible for ensuring that the contents of the operating
instructions are fully understood by the responsible personnel.
2.3 Non-compliance with safety instructions
Non-compliance with safety instructions can jeopardize the
safety of personnel, the environment and the machine / unit
itself. Non-compliance with these safety instructions will also
lead to forfeiture of any and all rights to claims for damages.
In particular, non-compliance can, for example, result in:
- failure of important machine/system functions,
- failure of prescribed maintenance and servicing practices,
- hazard to persons by electrical, mechanical and chemical
effects as well as explosion,
- hazard to the environment due to leakage of hazardous
substances.
2.4 Safety awareness
It is imperative to comply with the safety instructions contained
in thismanual, the relevant nationaland international explosion
protection regulations, health and safety regulations and the
operator’s own internal work, operation and safety regulations.
Ex symbol relates to additional requirements which
must be adhered to when the pump is operated in

2.5 Safety instructions for the operator / user
- Any hot or cold components that could pose a hazard must
be equipped with a guard by the operator.
- Guards which are fitted to prevent accidental contact with
moving parts (e.g. coupling) must not be removed whilst the
unit is operating.
- Leakages (e.g. at the shaft seal) of hazardous fluids
handled (e.g. explosive,toxic, hot) must be contained so as
to avoid any danger to persons or the environment. All
relevant laws must be heeded.
- Electrical hazards must be eliminated. (In this respect refer
to the relevant safety regulations applicable to different
countries and/or the local energy supply companies.)
- Any components in contact with the fluid pumped,
especially in the case of abrasive fluids, shall be inspected
for wear at regular intervals and replaced by original spare
parts (see section 2.7) in due time.
If the pumps/units are located in potentially explosive
atmospheres, it is imperative to make sure that
unauthorized modes of operation are prevented.
Non-compliance may result in the specified temperature limits
being exceeded.

2.6 Safety instructions for maintenance,
inspection and installation work
The operator is responsible for ensuring that all maintenance,
inspection and installation work be performed by authorized,
qualified specialist personnel who are thoroughly familiar with
the manual.
The pump must have cooled down to ambient temperature,
pump pressure must have been released and the pump must
have been drained.
Work on the machine / unit must be carried out only during
standstill. The shutdown procedure described in the manual for
taking the unit out of service must be adhered to without fail.
Pumps or pump units handling fluids injurious to health must be
decontaminated.
Immediately following completion of the work, all
safety-relevant and protective devices must be re-installed
and/or re-activated.
Please observe all instructions set out in the chapter on
”Commissioning” before returning the unit to service.
2.7 Unauthorized modification and
manufacture of spare parts
Modifications or alterations of the equipment supplied are only
permitted after consultation with the manufacturer and to the
extent permitted by the manufacturer . Original spare parts and
accessories authorized by the manufacturer ensure safety.The
use of other parts can invalidate any liability of the manufacturer
for consequential damage.
2.8 Unauthorized modes of operation
The warranty relating to theoperatingreliability and safety of the
unit supplied is only valid ifthe equipment is used inaccordance
with its designated use as described in the following sections.
The limits stated in the data sheet must not be exceeded under
any circumstances.
2.9 Explosion protection
If the pumps/units are installed in potentially explosive
atmospheres, the measures and instructions given in
the following sections 2.9.1 to 2.9.6 must be adhered to without
fail, to ensure explosion protection.
by starting up the unfilled pump unit, even for a short period, to
prevent temperature increases resulting from contact between
rotating and stationary components.
2.9.4 Pump operating mode
Make sure that the pump is always started up with the
suction-side shut-off valve fully open and the discharge-side
shut-off valve slightly open. However, the pump can also be
started up against a closed swing check valve. The
discharge-side shut-off valve shall be adjusted to comply with
the duty point immediately following the run-up process (see
6.1.7 ).
Pump operation with the shut-off valves in the suction
and/or discharge pipes closed is not permitted.
Caution
after a very short time, due to a rapid temperature rise in the
pumped fluid inside the pump.
Additionally, the resulting rapid pressure build-up inside the
pump may cause excessive stresses on the pump materials or
even bursting.
The minimumflows indicated in section 6.2.5 refer to water and
water-like liquids. Longer operating periods with these liquids
and at the flow rates indicated will not cause an additional
increase in the temperatures on the pump surface. However, if
the physical properties of the fluids handled are different from
water, it is essential to check if an additional heat build-up may
occur and if theminimum flow rate must therefore be increased.
To check, proceed as described in section 6.2.5.
In addition, the instructions given in section 6 of this operating
manual must be observed.
Both gland packings and mechanical seals may
exceed the specified temperature limits if run dry.
Dry running may not only result from an inadequately filled
seal chamber, but also from excessive gas content in the
fluid handled.
Pump operation outside its specified operating range may
also result in dry running.
In potentiallyexplosive atmospheres, gland packingsshall
only be used if combined with a suitable temperature
monitoring device.
In this condition, there is a risk of the pump
casing taking on high surface temperatures
2.9.1 Unit fill
It is assumed that the system of suction and discharge
lines and thus the wetted pump internals are completely
filled with the product to be handled at all times during pump
operation, so that an explosive atmosphere is prevented.
If the operatorcannot warrantthis condition, appropriate
monitoring devices must be used.
Caution
seal and the heating and cooling systems are properly filled.
2.9.2 Marking
The marking on the pump only refers to the pump part,
i.e.the coupling and motor must be regardedseparately.
The coupling must have an EC manufacturer’s declaration.The
driver must be regarded separately.
Example of marking on the pump part:
The marking indicates the theoretically available temperature
range as stipulated by the respective temperature classes.The
temperatures permitted for the individual pump variants are
outlined in section 2.9.5.
2.9.3 Checking the direction of rotation (see also 6.1.4)
If the explosion hazard also exists during the installation
phase, the direction of rotation must never be checked
In addition, it is imperative to make sure that the
seal chambers, auxiliary systems of the shaft
Ex II 2 G T1 - T5
2.9.5 Temperature limits
In normalpump operation, the highest temperatures are
to be expected on the surfaceof the pump casing, at the
shaft seal and in the bearingareas. The surface temperature at
the pump casing corresponds to the temperature of the fluid
handled.
If the pump is heated, it must be ensured that the temperature
classes stipulated for the plant are observed.
In the bearing bracket area, the unit surfaces must be freely exposed to the atmosphere.
In any case, responsibility for compliance with the
specified fluid temperature (operating temperature) lies
with the plant operator. The maximum permissible fluid
temperature depends on the temperature class to be
complied with.
The table below lists the temperature classes to EN 13463-1
and the resulting theoretical temperature limits of the fluid
handled. In stipulating these temperatures, any temperature
rise in the shaft seal area has already been taken into account.

sheet. If the pump is to be operatedat a higher temperature,the
data sheet is missing or if the pump is part of a pool of pumps,
the maximum permissible operating temperature must be
enquired from the pump manufacturer.
Based on an ambient temperature of 40 °C and proper
maintenance and operation, compliance with temperature
class T4 is warranted in the area of the rolling element bearings.
A special design is required to comply with temperature class
T6 in the bearing area. In such cases, and if ambient
temperature exceeds 40 °C, contact the manufacturer.
2.9.6 Maintenance
Only a pump unit which is properly serviced and maintai-
ned in perfect technical condition will give safe and reliable operation.
This also applies to the reliable function of the rolling element
bearings whose actual lifetime largely depends on the operating mode and operating conditions.
Regular checks of the lubricant and the running noises will prevent the risk of excessive temperatures as a result of bearings
running hot or defective bearing seals (also see section
7.2.2.2).
The correct function of the shaft sealmust be checked regularly.
Any auxiliary systems installed must be monitored, if necessary, to make sure they function correctly.
Gland packings must be tightened correctly, to prevent excessive temperatures due to packings running hot.
The permissible operating temperature of the
pump in question is indicated on the data
