WARNING!
Hazardous media / contamination of persons and
equipment
Possible consequence: Fatal or very serious injuries.
material damage
–
Ensure the device is resistant to the media being
conveyed
–
Always observe the safety data sheets for the
media to be conveyed. The system operator must
ensure that these safety data sheets are available
and that they are kept up-to-date
–
The safety data sheets for the media being con‐
veyed are always decisive for initiating counter
measures in the event of leakage to the media
being conveyed
–
Observe the general restrictions in relation to vis‐
cosity limits, chemical resistance and density
WARNING!
Service life of the diaphragm
Possible consequence: Fatal or very serious injuries
The service life of the diaphragm cannot be precisely
specified. For this reason, the possibility of fracture
and subsequent leakage of liquids must be taken into
account.
In addition, you must prevent particles from the defec‐
tive diaphragm reaching the media being conveyed.
This can be achieved e.g. by filtration, a hose rupture
alarm or other means suitable for the respective
process.
CAUTION!
Compressed air
Before working on the double diaphragm pump, close
the compressed air lines and vent the double dia‐
phragm pump.
Before undertaking any maintenance and repair work,
close off the compressed air supply, discharge the
compressed air and detach the air supply line from the
double diaphragm pump. The line to the discharge
side of the double diaphragm pump may be under
pressure and must likewise be vented.
CAUTION!
Hot surface
When conveying hot liquids, the pump can likewise
become hot. Hot surfaces may then be present on the
pump. Bear this in mind and take suitable measures to
reduce any hazards.
