WARNING!
Fire hazard with flammable media
Only with flammable media: They can be ignited by
oxygen.
– The pump may not work if there is a mixture of feed
chemical with oxygen in the liquid end. A specialist
may need to take appropriate actions (using inert
gas, ...).
CAUTION!
Feed chemical could escape
– Check suction and discharge lines, and liquid end
with valves for leak-tightness and tighten if neces‐
sary.
– Check whether the necessary flushing pipes or
bleed lines have been connected.
CAUTION!
Prior to commissioning, check that the pump and corre‐
sponding ancillary equipment is connected in compli‐
ance with the regulations.
CAUTION!
Adhere to the instructions in the frequency converter
operating instructions when using pumps with speed
control
CAUTION!
Danger resulting from unnoticed diaphragm rupture
If the pump has been ordered with an electric diaphragm
rupture sensor, it still has to be installed.
– Screw the enclosed diaphragm rupture sensor into
the liquid end.
CAUTION!
Warning of unnoticed diaphragm rupture
Only above approximately 2 bar system back pressure is
a signal generated upon a diaphragm rupture.
– Only rely on the diaphragm rupture sensor at back
pressures greater than 2 bar.
