Prevent internal condensation, transfer of liq-
uids or dust. The diaphragms and valves will
be damaged, if liquids are pumped in signifi-

Check the pump regularly for external soiling
and deposits. Clean the pump if necessary
to avoid an increase of the pump’s operating
temperature.

Avoid overheating (e.g., due to hot process
gases). Maximum permissible temperature
range: see “Gas inlet temperatures”, pg. 27.
Make sure the fans’ air supply is adequate.
Do not place the pump on soft surfaces (e.g.,
rubber foam) during operation. This may re-
duce the air circulation in the pump housing
and affect the fans’ cooling effect. Check fans
regularly for dust/dirt. Clean fan guard grills if
necessary to avoid a reduction of ventilation.
