CAUTION!
Danger resulting from unnoticed diaphragm rup‐
ture
If the pump has been ordered with an electric dia‐
phragm rupture sensor, it must also be electrically
installed.
– Electrically wire the enclosed diaphragm rup‐
ture sensor to a suitable monitoring device.
Make sure that the monitoring/feed equipment installed by the cus‐
tomer is capable of evaluating the current variations of the Namur
sensor to indicate a diaphragm rupture!

When using flammable media:
WARNING!
Risk of fire with flammable feed chemicals
Make sure that the electric diaphragm rupture
sensor switches off the pump immediately after a
diaphragm rupture.
– Connect the pump and diaphragm rupture
sensor to a control so that the pump stops
immediately in the event of a diaphragm rup‐
ture.
