Safety chapter
CAUTION!
Warning of feed chemical spraying around
The metering pump can generate a mul‐
tiple of its rated pressure. Hydraulic parts
may burst if a discharge line is blocked.
–
Correctly install a back pressure valve
in the discharge line behind the
metering pump.
CAUTION!
Warning of excessive demand
The pump can meter too much if there is a
negative pressure difference between the
discharge and suction sides.
–
For example with a free outlet, use a
back pressure valve with a minimum
opening pressure of 1.5 bar (not pos‐
sible with 0213).
CAUTION!
Danger of injury to personnel and material
damage
The use of untested third party compo‐
nents can result in injury to personnel and
material damage.
–
Only fit parts to metering pumps that
have been tested and recommended
by ProMinent.
CAUTION!
Warning against illegal operation
Observe the regulations that apply where
the unit is installed.

Information in the event of an emergency
In an emergency, either pull out the mains plug,
turn the multifunctional switch to "Stop" or press
the Emergency Stop switch installed on the
customer's side or disconnect the pump from
the mains power supply in line with the emer‐
gency shut-down management guidelines for
your system!
If feed chemical escapes, additionally ensure
that the hydraulic system around the pump is at
atmospheric pressure. Adhere to the safety
data sheet for the feed chemical.
