MAJOR COMPONENTS
AND
WHAT THEY DO
Piping
Relief
Valve
A Shallow well jet pump can be installed
on a dug well,
drilled well or with a driven point. In a dug or ased well, a
foot valve and strainer should be installed for easy priming.
It should be five to ten feet below the lowest level to which
the water will drop while pump is operating
(pumping
water level).

Built-in
Check
Valve
The strainer should not be too close to the bottom or sediment may clog it. Before installing the foot valve, check to
see that it works freely.
When installed
on a driven pont well, your Shallow Well
Jet Pump should have a check valve installed as shown in
Figure 2.

Impeller turns with motor shaft, causing the water to fly out
from its rim by centrifugal force. Impeller rotation creates a
vacuum which puUs 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.

Point
In shallow wells (less than 20 feet deep), the vacuum created at the pump is enough
to pull water to the pump.
Therefore,
for shallow well use the jet is built into the pump.

Tank
The tank serves two functions.
It provides
a reservoir
of
water, some of which can be drawn through the house fixture before the pump must start. It maintains
a cushion of

Figure 2
For a pump at sea level, be sure the vertical distance (lift)
from the pumping water level to the pump is not over 20
feet if the pump is over the well. This wll be less if the pump
is offset from the well.
The maximum
lift of any pump decreases at the rate of about
1' less lifx for every 1,000 feet elevation above sea level. For
example,
if your are at 5,000 feet elevation
such as in
Denver, Colorado, you would loose five feet of llfx. The maximum depth from which oyou could pump water would

for Service
and Replacing Shaft Seal
Lubrication
If it is necessary to separate motor and seal plate,
place the shaft seal. We suggest you purchase
U109_A, and have it on hand for future use.
It is not necessary
to lubricate
the pump or its motor. The
motor bearings are lubricated
for life. The mechanical
shaft
seal in the pump is water lubricated
and self-adjusting.
NOTICE: The seal consists of two parts, a rotating member
and a ceramic seat. The surfaces of the seal are easily damaged. Read instructions
carefully.
Remove
Draining
for Winter
When the pump is to be disconnected
from service or is in
danger of freezing, it must be drained.
To drain it, turn off
power and relieve all pressure
on the system. Remove pressure switch
tubing from the side of the pump housing.
Remove the priming plug to vent the pump. Drain the pressure tank; drain all piping to a point below the freeze line.
To drain an air volume
control
(AVC), remove
the tubing
from it and turn the AVC upside down. This will permit any
water in the AVC to drain into tank.

A good way of delivering gas-free water is to suspend a pipe,
closed at the bottom
and open at the top, surrounding
the
suction
pipe. Since the gases rise in the well casing, the
water sucked down through
the pipe and into the suction
pipe is free of gas. This type of well must be vented to the
outside of any enclosure.
