CAUTION
Safety instruction
●
Countermeasure against static electricity
When low electric conductivity liquid such as the ultra-pure water and
the fluor inactive liquid (e.g. Fluorinert™) are handled, static electricity
may generate in the pump, which may cause a static discharge and the
pump breakage. Take a countermeasure for removing static electricity.
●
When pump is stopped
•
When pump is stopped, release 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
when pump is stopped to avoid impactive pressure resulting in defor-
mation of bellows or connecting plate.
●
Pump at halt
•
Do not supply air to both the right and left air-supply ports at the same
time to prevent the bellows from deformation.
•
If the pump or dampener is stopped for a long time with the liquid
inside, the gas may be generated to penetrate the bellows and cor-
rode the metallic parts. When the pump or dampener is stopped for 2
days or more, operate them for about 10 minutes a day to replace the
air.
●
Air exhaust port
Do not choke (make tube dia. smaller) air exhaust port to avoid bellows
deformation due to residual air.
●
Before operating the pump & dampener
Fully open pump suction and discharge valves. Confirm that liquid is
filled in piping.
●
Supply air pressure
Do not supply air exceeding 0.5 MPa to prevent bellows from deforma-
tion.
●
Prohibited liquids
Do not handle the following liquids.
•
Liquid easily crystallizes
•
Liquid containing slurry
•
Solvent naphtha, stripping agents or solvents
●
Disposal of used dampener
Disposal of used or damaged dampener must be done in accordance
with local laws and regulations. (Consult a licensed industrial waste
products disposing company.)
●
Do not close a discharge valve which is positioned beyond the
dampener in operation.
Impactive pressure may deform the pump and dampener.
