MAJOR COMPONENTS
AND
WHAT
THEY DO
Impeller
and Jet
Impeller
turns
with
motor
shaft,
causing
water
to fly out from
its
rim by centrifugal
force.
Impeller
rotation
creates
a vacuum
which
pulls
in more
water.
Part of the water
is diverted
back
to the jet
where
it passes
through
the nozzle
and venturi.
This creates
more
vacuum
to draw
in more
water.
In shallow
webs
(less than 20 feet deep),
the vacuum
created
at the
pump
is enough
to pull water
to the pump.
Therefore,
for shallow
web use the jet is built into the pump.
Pre-Charged
Tank
The
tank serves
two
functions.
It provides
a reservoir
of water
under
pressure
and maintains
a cushion
of air pressure
to prevent
pipe
hammering
and possible
damage
to plumbing
components.
When
water
is drawn
off through
the house
fixtures,
the pressure
in the tank is lowered
and the pump
starts.
Pressure
Switch
The pressure
switch
provides
for automatic
operation.
Pump starts
when
pressure
drops
to 30 pounds
and
stops
when
pressure
reaches
50 pounds.
Check Valve or Foot Valve
This pump
is equipped
with
a built:m
check
valve. Install a check
valve
as close
to well
as possible
on web point
installations.
A
foot valve must
be installed
in the well
on dug or cased
wells.
See
Figures 2A and 2B. For long horizontal
pipe runs, install check
valve
as close
to web as possible
(all types of wells).
INSTALLATION
Piping
in the Well
The
Shallow
Well
Water
System
can be installed
on a dug well,
cased
well or with
a driven
point.
In a dug or cased
well,
a foot
valve and strainer
should
be installed
for easy priming.
It should
be
installed
five to ten feet below
the lowest
level to which
the water
will drop
while
the pump
is operating
(pumping
water
level).
To
keep
sediment
from
clogging
the strainer,
be sure it is five to ten
feet above
the bottom
of the well.
Before installing
the foot valve,
make sure that it works
freely.
Figure
I - Connections
to water
system
When
installed
on a driven
point
well,
your
Shallow
Well
Water
System
should
have a check
valve installed
as shown
in Figure 2A.
For a pump
at sea level mounted
directly
over the well, be sure the
total
lift from
the pumping
water
level
to the pump
does
not ex-
ceed
20 feet. This will be less if the pump
is offset from
the weB.
The maximum
lift of any pump
decreases
at the rate of about
1'
less lift for every
1,000
feet of elevation
above
sea level.
For ex-
ample,
at Denver,
Colorado
(Elev. 5,000')
the pump
loses five feet
of lift. The
maximum
depth
from
which
it would
pump
water
would
therefore
be 15 feet.
