NOTE
WARNING
A) The arrangement of the metering pump should preferably
be made on and/or over the metering container.
NOTE
B) For easy venting of the metering pump with an applied
metering backpressure > 0.05 MPa (0.5 bar), an appropriate
ball (Pos. 4) valve can be installed in the pressure pipe. The
venting pipe should be led back pressure-free into the
container
WARNING
C) Between the back-pressure in the injection point and the
pressure at the metering pump a positive difference of
pressure must prevail of at least 0.1 MPa (1 bar). If this is
not the case, a pressure control valve (Pos. 2) must be built
into the metering line.
In addition it recommends to install itself for the avoidance of inadmissibly high pressures
in the metering line an appropriate safety overflow valve (Pos. 3). The by-pass pipe of this
valve should be led back pressure-free into the container.
WARNING
The overflow line never be fed back into the suction line of the metering pump.
In place of a pressure valve and an overflow valve also a multifunction valve (MFV) from our
NOTE
delivery program can be used.
D) A spring-loaded injection or metering valve (Pos. 1) should be installed at the injection
point (including with supplying metered amounts into depressurised systems).
For outgassing media and products with a viscosity of > 100 mPas,
flooded suction is recommended.
In using this method, however, ensure that the injection point is
positioned over the discharge container and/or an appropriate
pressure control valve (Pos. 2) is installed. These measures prevent
the discharge container from being siphoned empty.

The installation examples and applications provided here are of a functional nature. They
give an overview of installation types which are correct or to be avoided for the correct
functioning of the pump.
Specific measures and protection devices for the metering of dangerous or aggressive
chemicals are not provided here.
When using such chemicals, always observe the legal regulations and the relevant product
datasheet.
For media with a tendency towards
sedimentation, the bottom admisson valve or foot
valve of the suction line / suction lance must be
fitted above the anticipated layer of sludge.
The venting pipe must never be fed back into the
suction line of the metering pump!
