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 di-
verted
back to the jet where
it passes through
the nozzle and
venturi. This creates
more vacuum
to draw in more water.
In shallow
wells (less than
20 feet deep),
the vacuum
cre-
ated
at the pump
is_enough
to pull water
to toe pump.
Therefore,
for shallow
_-ell 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 pres-
sure
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
pressnre
drops
to 40 pounds
and stops
when
pressure
reaches
60 pounds.
Check
Valve or Foot Valve
This pump
is equipped
with a built-in
check
valve. Install a
check
valve as close
to well as possible
o_ well point
in-
stallations.
A foot valve must be installed
in the well on dug
or cased wells. See Figures ZA and 2B, Page 4. For long hor-
izontal pipe runs, install check valve as close to well as pos-
sible (all types of wells).
