3 Safety
Observe the safety notices in Chapters
and
The pumps are produced in accordance with the generally recognized
rules of engineering, as well as the occupational health, safety and acci-
dent prevention regulations. Nevertheless, dangers can arise during their
use that lead to injuries to the user or third parties or to damage to the
pump or other property.
Only use the pumps in perfect technical condition, for their intended use,
safely and aware of the dangers and in observation of the operating and
installation instructions.
The components that are to be connected to the pumps must be designed
according to the pneumatic data of the pumps.
When connecting the pumps to the electrical power, observe the corre-
sponding safety rules.
Personnel Make sure that only specially trained and instructed personnel work on the
pumps. This applies, in particular, to assembly, connection and service
work.
Make sure that the personnel have read and understood the operating and
installation instructions, particularly the chapter on safety.
Working in a safety conscious
manner
Observe the regulations on accident prevention and safety during all work
on the pumps and during operation.
Avoid contact with the heads and housing parts, as the pump heats up
during operation and may remain hot for some time after operating.
When working on the pump, make certain that the pump is disconnected
from mains and without power.
Ensure that no hazards arise from gas flowing when gas connections are
open, from the effects of noise or from hot, corrosive, dangerous and envi-
ronmentally hazardous gases.
Make sure that an EMC-compliant installation of the pump is ensured at all
times to prevent the occurrence of dangerous situations.
Handling of hazardous media Upon breakage of the diaphragm and/or leaks, the transferred medium
mixes with the air in the surroundings and/or in the pump housing. Make
sure that a dangerous situation cannot arise as a result.
When pumping hazardous media, observe the safety regulations for the
handling of said media.
Handling of combustible media Note that the pumps are not designed to be explosion-proof.
Make certain that the temperature of the medium is always sufficiently be-
low the ignition temperature of the medium so as to prevent ignition or ex-
plosion. This also applies for abnormal operating situations.
Note that the temperature of the medium increases when the pump com-
presses the medium.
Therefore, make certain that the temperature of the medium also remains
sufficiently below the ignition temperature of the medium even when it is
compressed to the maximum permissible operating pressure of the pump.
The maximum permissible operating pressure of the pump is stated in
Chapter
.
Make certain that the permissible ambient temperature (
is not exceeded.
Where applicable, also take into account external energy sources (such as
radiation sources) that could additionally heat the medium.
