The pumps are not suitable to pump any of the sub-
stances listed below.
Do not pump:
- unstable substances
- substances which react explosively under impact
(mechanical stress) without air
- substances which react explosively when being ex-
posed to elevated temperatures without air,
- substances subject to auto-ignition,
- substances which are inammable without air
- explosive substances.
The pumps are not approved for operation below
ground. Do not operate the pump below ground.
Do not pump substances which may form depos-
its inside the pump. The pumps are not suitable for
pumping substances which may form deposits inside
the pump. Deposits and condensate in the pump may
lead to increased temperatures even to the point of
exceeding the maximum permitted temperatures.
Check the inlet and outlet of the pump, if there is a
danger of forming deposits inside the pump, e.g., in
the pump chambers (the pump chamber is the part
between diaphragm and head cover. See section „Re-
placing diaphragms and valves“, pg. 99). Inspect the
pump chambers regularly and clean if necessary.
Consider interactions and chemical reactions of
the pumped media. Ensure that the materials of the
pump’s wetted parts are compatible with the pumped
substances, see section „Technical data“, pg. 27.
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
