CAUTION!
Uncontrolled flow of feed chemical
Feed chemical can press through the metering
pump in an uncontrolled manner in the event of
excessive priming pressure on the suction side of
the metering pump.
– Do not exceed the maximum permissible pri‐
ming pressure for the metering pump or
– Set up the installation properly.
CAUTION!
Warning about lines coming loose
Suction, discharge and relief lines installed incor‐
rectly can come loose from the pump connection.
– Only use original hoses with the specified hose
diameter and wall thickness.
– Only use clamp rings and hose nozzles that fit
the respective hose diameter.
– Always connect the lines without mechanical
tension.
– Only connect steel piping via a flexible piping
section to a plastic valve body - see the fol‐
lowing figure.

CAUTION!
Warning of feed chemical spraying around
PTFE seals, which have already been used / com‐
pressed, can no longer reliably seal a hydraulic
connection.
– New, unused PTFE seals must always be
used.
CAUTION!
Warning of backflow
Liquid ends, foot valves, back pressure valves,
relief valves or spring-loaded injection valves do
not constitute absolutely leak-tight sealing ele‐
ments.
– Use a shut-off valve, a solenoid valve or a
vacuum breaker for this purpose.
