• Install a cold trap in front of the pump if pumping ag-

gressive or corrosive gases or vapors.

•

Consider interactions and chemical reactions of

the pumped media. Ensure that the materials of the

pump’s wetted parts are compatible with the pumped

When changing the substances pumped, we recom-

mend purging the pump with air or inert gas prior to

changing the pumped media. Purging the pump will

pump out residues and it will reduce the possibility of

reactions of the pumped substances with each other

and with the pump’s materials.

Safety during operation

➨

Adopt suitable measures to prevent the release of dan-

gerous, toxic, explosive, corrosive, noxious or polluting

fluids, vapors and gases. To prevent any emission of

such substances from the pump outlet, install an ap-

propriate collecting and disposal system and take pro-

tective action for pump and environment.

➨

You must take suitable precautions to prevent any for-

mation of explosive mixtures in the expansion cham-

ber, in the oil reservoir, in the pump chamber of the dia-

phragm pump, or at the outlet of the pump. In case, e.g.,

of a diaphragm failure, mechanically generated sparks,

hot surfaces or static electricity may ignite these mix-

tures. Use inert gas for gas ballast or venting, if neces-

sary.

➨

Drain appropriately or otherwise remove any potential-

ly explosive mixtures at the outlet of the pump, or dilute

them with inert gas to non-explosive concentrations.

➨

Never operate this pump if it has a damaged cord or

plug.
