Safety

Note the safety precautions in sections 6. Installation and
connection, and 7. Operation.
The pumps are built according to the generally recognized rules of
technology and in accordance with the occupational safety and
accident prevention regulations. Nevertheless, dangers can result
during their use which lead to injuries to the user or others, or to
damage to the pump or other property.
Only use the pumps in proper technical condition and in accord-
ance with their intended use in a safety and danger-conscious
manner while observing the operating- and installation instructions.
Make sure that only trained and instructed personnel or specially
trained personnel work on the pumps. This especially applies to
assembly, connection and servicing work.
Make sure that the personnel has read and understood the operat-
ing- and installation instructions, and in particular the "Safety"
chapter.
Observe the accident prevention and safety regulations when
performing any work on the pumps and during operation.
When classifying a pump environment in a hazardous area (zone),
observe the "Guidelines for the Avoidance of Dangers due to
Explosive Atmospheres with Collection of Examples – Explosion
Protection Guidelines – (EX-RL)".
In as much as special cases are concerned or there is doubt as to
the specification of the hazardous areas, inform the supervisory
authorities and have them decide.
For use in hazardous environments containing combustible gases,
vapours and aerosols the lowest ignition temperature of a possible
hazardous atmosphere must be higher than the so-called "maxi-
mum surface temperature" of the pump.
The maximum surface temperature is defined in DIN EN 13463-1
as the highest temperature obtainable in operation under the least
favourable conditions (but within recognized tolerances) by any
part or surface of the pump.
The maximum surface temperature is determined by the construc-
tion of the pump and indicated on the type-plate as the tempera-
ture class.
When transferring dangerous media, observe the safety regula-
tions when handling these media.
Store all replacement parts in a protected manner and dispose of
them properly in accordance with the applicable environmental
protection regulations. Observe the respective national and inter-
national regulations. This especially applies to parts contaminated
with toxic substances.
