Safety Section
CAUTION
•
Stopping pump operation
·
When stopping pump operation, release the pressure on the discharge side first.
Otherwise, the bellows may be deformed due to the residual pressure on the
pump discharge side.
·
If a valve is provided on the discharge side, do not close the valve upon stopping
the pump. The resulting impactive pressure may deform the bellows or connect-
ing plate.
•
Pump at halt
Do not supply air to both the right and left air-supply ports at the same time, to pre-
vent the bellows from becoming deformed.
•
Note for electrode
There is a case which electrode could not detect leakages. This comes from oper-
ating condition (supply air pressure etc) and size of crakes on the bellows. please
contact IWAKI for detail.
•
Static electricity
When low electric conductivity liquids such as ultra-pure water and fluor inactive liq-
uid (e.g. Fluorinert
TM
) are handled, the static electricity may be generated in the
pump, which may cause static discharge and pump break down. Take countermea-
sures to avoid and remove the static electricity.
