only
a

carefully
read

in
them.
Self
‐
priming
pump
KSP.
A
variant
of
the
ZH
‐
3208
pump.
ZH
3208
is
a
normal
multi
‐
stage
centrifugal
pump
with
several
impellers
that
can
achieve
high
pressures.
Several
impellers,
so
‐
called
stages,
are
built
in
a
row
on
a
shaft.
However
as
a
centrifugal
pump,
the
ZH
is
not
self
‐
priming
and
also
does
not
have
dry
run
protection.
By
integrating
a
suction
stage
in
our
ZH
pump,
additional
properties
such
as
self
‐
priming
and
dry
run
protection
are
achieved.
The
new
KSP
pump
can
then
prime
liquids
from
a
tank
that
is
positioned
lower
and
is
not
damaged
by
a
brief
dry
run.
Function:
The
pump
consists
of
two
pump
types
that
are
mounted
on
a
drive
shaft.
A
multi
‐
stage
centrifugal
pump
can
then
only
operate
when
the
inside
of
the
pump
is
always
filled
with
liquid.
This
works
very
well
when
the
pump
has
an
inflow
or
the
suction
line
is
always
completely
filled.
For
example,
this
is
possible
by
using
a
foot
valve.
If
the
pump
has
a
suction
lift
instead
of
an
inflow
and
no
foot
valve
can
be
used,
the
pump
will
quickly
run
dry
and
can
then
no
longer
convey
any
liquid
or
build
up
pressure.
Here
it
must
first
be
ensured
that
the
liquid
completely
fills
the
pump
and
the
complete
suction
line
again.
An
integrated
suction
stage
is
used
here.
This
is
positioned
on
the
same
shaft
after
the
centrifugal
pump
stages.
When
priming,
the
medium
from
the
suction
tank
is
transported
through
the
suction
line
in
the
pump,
through
all
pump
stages
of
the
centrifugal
pump
and
finally
through
the
suction
stage.
This
arrangement
of
the
stages
ensures
that
the
stages
of
the
centrifugal
pump
are
slowly
filled
until
the
pump
is
fully
filled
with
liquid.
