Maintenance (Continued)
4. If seal does not seat correctly after
recleaning cavity, place a cardboard
washer over polished seal face and
carefully press into place using a
piece of standard 3/4” pipe as a
press.
IMPORTANT: Be sure you do not
scratch seal face.
5. Dispose of cardboard washer and
recheck seal face to be sure it is free
of dirt, foreign particles, scratches,
and grease.
6. Inspect shaft to be sure it is free of
nicks and scratches.
7. Reassemble seal plate to motor
flange.
8. Apply liquid soap sparingly (one
drop is sufficient) to inside diameter
of rotating seal member.
9. Slide rotating seal member (carbon
face first) onto shaft until rubber
drive ring hits shaft shoulder.
IMPORTANT: Be sure not to nick or
scratch carbon face of seal when
passing it over threaded shaft end or
shaft shoulder. The carbon surface
must remain clean or short seal life will
result.
10. Hold motor shaft with 7/16” open
end wrench on shaft flats and
screw impeller onto shaft. Be sure
you do not touch capacitor
terminals with body or any metal
object. Tightening impeller will
automatically locate seal in correct
position.
11. Remount diffuser on seal plate.
12. Follow instructions under “Pump
Reassembly”.
PUMP REASSEMBLY
1. Install new gasket; mount motor on
pump body and install four
capscrews.
2. Replace pressure switch tubing and
motor wiring; close drain cock.
3. Prime pump according to
instructions under “Operation”.
4. Check for leaks.
HELPFUL HINTS
HOW TO AVOID OVERPUMPING
A SHALLOW WELL
In the section on “Priming the Shallow
Well Pump,” the instructions were to
open the control valve all the way
after the pump starts to deliver water.
If you are overpumping the well,
partially close the control valve on the
jet pump. This will reduce the
discharge of water from the pump.
HOW TO HANDLE A GASEOUS WELL
In some areas, well water contains
gases which must be allowed to escape
before the water is used. To deliver
gas-free water, suspend a pipe, closed
at the bottom and open at the top, so
it surrounds the suction pipe inlet. (See
Figures 34 and 35). Since the gases rise
in the well casing, the water sucked
down through the pipe and into the
suction pump is free of gas. This type
of well must be vented to the outside
of any enclosure.
