3 Use
3.1 Proper use
The pumps are intended exclusively for transferring gases
and vapors.
Responsibility of the owner
Only install and operate the pumps in accordance with the op-
erating parameters and conditions described in Chapter 6
Technical data [} 20]and Chapter Use in potentially explo-
sive areas.
Pumps with ATEX designation do not always satisfy the
regulations for potentially explosive areas in countries
outside of the EU.
Only install and operate the pumps in accordance with the op-
erating parameters and conditions described in Chapter 6
Technical data [} 20].
Only pumps that are fully assembled and in the condition as
delivered may be operated.
Make sure that the installation location is dry and that the
pump is protected against rain, splash, gushing, and drip wa-
ter as well as from other contaminants.
The pump may not be used in explosive areas. The Ex-desig-
nation is valid only for the transfer chamber (media-contacting
area).
Check the tightness of the connections between the pipes of
the application and the pump (or the connection of the pump)
at regular intervals. Leaky connections carry the risk of re-
leasing dangerous gases and vapors from the pump system.
Before transferring a medium, check whether the medium can
be transferred danger-free in the specific application.
Before using a medium, check the compatibility of the media-
contacting components (see 6 Technical data [} 20]) with the
medium.
Make certain that no risk of explosion arises even in extreme
operating situations (temperature, pressure) and in the event
of system breakdowns.
