circulation
pumps
permit
the
integral
control
of
pressure
difference,
whereby
the
pump
outputs
can
be
adapted
to
the
effective
system
requirements.
This
saves
energy,
improves
control
of
the
system,
and
reduces
the
noise
level.

Pumped
media
Pure,
highly
fluid
liquids
that
are
suitable
for
central
heating
systems.
The
water
should
comply
with
conventional
standards
such
as
e.g.
VDI
2035.
The
medium
may
not
contain
any
aggressive
or
explosive
additives.
Similarly,
the
admixture
of
mineral
oils
or
fibrous
particles
is
not
permitted.
The
pump
may
not
be
used
to
convey
flammable
or
explosive
media.
The
water
may
not
contain
hydrocarbon
derivates
or
aromatic
products.
If
an
antifreeze
medium
must
be
added,
its
proportion
may
not
be
more
than
30%.
