Assembly and Installation

CAUTION!
Warning of feed chemical spraying around
The pipes can loosen or rupture if they are
not installed correctly.
Route all hose lines so they are free
from mechanical stresses and kinks.
Only use original hoses with the
specified hose dimensions and wall
thicknesses.
Only use clamp rings and hose noz‐
zles that are intended for the hose
diameter in question to ensure the
long service life of the connections.
CAUTION!
Warning of feed chemical spraying around
PTFE seals, which have already been
used / compressed, can no longer reliably
seal a hydraulic connection.
Always use new, unused PTFE seals.
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!
Warning of destruction of the pump
An incorrect mains voltage or mains fre‐
quency can irreparably destroy the
metering pump.
Check that the mains voltage and fre‐
quency agree with the values given
on the nameplate.
CAUTION!
Warning against illegal operation
Observe the regulations that apply where
the unit is installed.
Capacity too low
The liquid end valves can be disturbed by
vibrations.
Secure the metering pump to ensure
that no vibrations can occur.
