Before working on the double diaphragm pump, check whether it is
necessary to close the compressed air lines and vent the double
diaphragm 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. These meas‐
ures depend on the configuration of your compressed air supply.
The line to the discharge side of the double diaphragm pump may
be under pressure and must likewise be vented if required.
The pump can also become hot when conveying hot liquids. There
can then be hot surfaces on the pump. Bear this in mind and take
suitable measures to reduce any hazards.
Depending on the operating conditions, the maximum sound pres‐
sure level of the device can reach 88 dB ± 3 dB. Bear this in mind
and take appropriate measures to reduce any impact caused by
this sound pressure level. The type and implementation of suitable
measures depends on the local circumstances and is the responsi‐
bility of the system operator.
Take suitable measures to protect the device from environ‐
n
mental influences when operating outside such as:
–
UV radiation
–
Humidity
–
Frost, etc.
Check that all fastening elements with sealing rings are correctly
seated before commissioning the double diaphragm pump. The
seals may "creep" so that the fastening elements may come loose
over time.
