Danger points
3.1 Hazards when working with the
system
The progressing cavity pump was built
according to the current state of technology
and recognized safety regulations.
Nevertheless, danger to life and limb of the
user or third parties may arise during use of
the pump or damage may occur to the system
or other property.
Dangerous parts of the system include:
•
Moving parts
•
Components of the electrical equipment
(mains connection).
Hazardous materials include:
•
Poisonous materials
•
Materials that are hazardous to health
•
Acidic materials
•
Irritants
•
Potentially explosive materials
•
Oxidants; highly, easily, and flammable
materials
•
Carcinogens
•
Teratogenic materials
•
Mutagens
•
Materials that are hazardous to humans in
other ways.
3.2 Dangers of leaks
Leaks (such as at the shaft seal) of hazardous
pumped liquids (explosive, poisonous, hot,
etc.) must be led away in such a way that there
is no danger to people or the environment.
Always obey all legally defined directives.
3.3 Dangers of electrical energy
Electrical hazards are present when working
on the pump, such as:
•
through direct contact with live parts or
parts that have become energized due to
faulty conditions
•
through electrostatic energy
•
through high voltage
•
through short circuits and overloads
Only electrical technicians may perform work
on the electrical power supply.
The machine’s electrical equipment must be
inspected on a regular basis. Loose
connections and charred cables must be
removed immediately.
Proper earthing must be provided whenever
there is the potential for electrostatic charges.
If it is necessary to work on live parts, always
work with a second person who can shut off
the main switch in an emergency.
3.4 Hazards caused by dust
When operating pump units in dust-filled
environments (such as in a mill, during
production of particle board, in a baked goods
factory, etc.) regularly clean the surfaces of the
pumps and motors according to the actual
concentration of dust in order to maintain the
cooling effect and eliminate the possibility of
spontaneous ignition.
Refer to explosion
protection directives (BGR 104)
3.5 Dangers of moving parts
The safety guarding for moving parts (such as
the coupling) may not be removed while the
machine is in operation.
3.6 Danger of hot or cold parts
If hot or cold parts represent a hazard, these
parts must be secured against contact at the
site of installation.
3.7 Operating in potentially
explosive atmospheres
If the pump or pump unit is operated in
potentially explosive atmospheres, follow the
ATEX supplemental instructions.
3.8 Danger of pumped liquid
Squirting pumped liquid can cause injury or
poisoning. Use the proper protective clothing
whatever working at the pump.
