6.1.1 Installation examples
NOTE
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.
WARNING
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.
A) The arrangement of the metering pump should preferably be
made on and/or over the metering container.
NOTE
For media with a tendency towards sedimentation,
the bottom admission valve or foot valve of the
suction line / suction lance must be fitted above
the anticipated layer of sludge.
B) 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.
Fig. 6.1
NOTE
In place of a pressure valve and an overflow valve also a multifunction valve (MFV) from our
delivery program can be used.
C) A spring-loaded injection or metering valve (pos. 1) should be installed at the injection point
(including with supplying metered amounts into depressurised systems).
D) For easy venting of the metering pump, the vent connection (see chapter 5.1, “Setup”,
Pos. 6) should be fed back into the metering medium container via a separate pipe.
WARNING
The venting pipe must never be fed back into the suction side of the metering pump!
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.
