A
centrifugal
pump
converts
the
input
power
to
kinetic
energy
in
the
liquid
by
accelerating
the
liquid
by
a
revolving
device
‐
an
impeller.
Fluid
enters
the
pump
through
the
eye
of
the
impeller
which
rotates
at
high
speed.
The
fluid
is
accelerated
radially
outward
from
the
pump
chasing.
A
vacuum
is
created
at
the
impellers
eye
that
continuously
draws
more
fluid
into
the
pump.
The
energy
created
by
the
pump
is
kinetic
energy
according
the
Bernoulli
Equation.
The
energy
transferred
to
the
liquid
corresponds
to
the
velocity
at
the
edge
or
vane
tip
of
the
impeller.
The
faster
the
impeller
revolves
or
the
bigger
the
impeller
is,
the
higher
will
the
velocity
of
the
liquid
energy
transferred
to
the
liquid
be.
This
is
described
by
the
Affinity
Laws.
it
is
important
to
understand
that
the
pump
will
pump
all
fluids
to
the
same
height
if
the
shaft
is
turning
at
the
same
rpm.
Centrifugal
Pumps
are
"
constant
head
machines
".
