PREPARATION INSTALLATION (Continued)
BASIC TOOLS AND MATERIALS NEEDED
Pipe Wrenches Screwdriver
Hacksaw Check Valve
Adjustable Wrench Teflon Tape
Knife
NOTICE: Depth to water must not be more than 20’.
1. Long runs and many fittings increase friction and reduce
flow. Locate pump as close to water source as possible:
use as few elbows and fittings as possible.
2. Be sure water is clear of sand. Sand will plug the pump
and void the warranty.
3. Protect pump and all piping from freezing. Freezing will
split pipe, damage pump and void the warranty. Check lo-
cally for frost protection requirements (usually pipe must
be 12” below frost line and pump must be insulated).
4. Be sure all pipes and foot valve are clean and in good
shape.
5. No air pockets in suction pipe.
6. No leaks in suction pipe. Use Teflon tape or Plasto-Joint
Stik1to seal pipe joints.
7. Unions installed near pump and water source will aid in
servicing. Leave room to use wrenches.
8. Pump body may explode if used as a
booster pump. DO NOT use in a booster application.

INSTALLATION
NOTICE: Use the installation method below which matches
your well type.
CASED WELL INSTALLATION
1. Inspect foot valve to be sure it works freely. Inspect
strainer to be sure it is clean.
2. Connect foot valve and strainer to the first length of suc-
tion pipe and lower pipe into well. Add sections of pipe
as needed, using Teflon tape on male threads. Be sure that
all suction pipe is leakproof or pump will lose prime and
fail to pump. Install foot valve 10 to 20 feet below the low-
est level to which water will drop while pump is operat-
ing (pumping water level). Your well driller can furnish
this information.
3. To prevent sand and sediment from entering the pump-
ing system, the foot valve/strainer should be at least 5 feet
above the bottom of the well.
4. When the proper depth is reached, install a sanitary well
seal over the pipe and in the well casing. Tighten the bolts
to seal the casing.
5. When using a foot valve, a priming tee and plug as shown
in Figure 1 are recommended.
DUG WELL OR OPEN WATER
INSTALLATION
1. Follow cased well installation, steps 1, 2, 3 and 5.
DRIVEN POINT INSTALLATION
1. Connect the suction pipe to the drive point as illustrated in
Figure 2. Keep horizontal pipe run as short as possible. Use
Teflon tape on male pipe threads. Multiple well points may
be necessary to provide sufficient water to pump.
2. Install a check valve in piping as shown in Figure 2. Flow
arrow on check valve must point toward pump.
HORIZONTAL PIPING FROM WELL TO
PUMP
1. Never install a suction pipe that is smaller than the suc-
tion tapping of the pump.

flow arrow points toward pump.
DISCHARGE PIPE SIZES
1. If increasing discharge pipe size, install reducer in pump
discharge tapping. Do not increase pipe size by stages.
2. When the pump is set away from the points of water use,
the discharge pipe size should be increased to reduce
pressure losses caused by friction.
• Up to 100’ run: Same size as pump discharge tapping.
• 100’ to 300’ run: Increase one pipe size.
• 300’ to 600’ run: Increase two pipe sizes.
LAWN SPRINKLING APPLICATION
This pump is designed for lawn sprinkling. It is designed to
deliver plenty of water at full sprinkler pressure. It can pump
from a pond, cistern or well points.
Pump discharge can be divided to supply two (2) or more
sprinkler systems. A suggested multiple discharge to service
is shown in Figure 3.
Do not use in a pressure tank or booster pump
application.
Pump/Piping Installation
PUMP INSTALLATION
NOTICE: Use Teflon tape supplied with the pump for mak-
ing all threaded connections to the pump itself. Do not use
pipe joint compounds on the pump: they can react with
the plastic in the pump components.
1. Bolt pump to solid, level foundation.
2. Support all piping connected to the pump.
3. Wrap 1-1/2 to two layers of Teflon tape clockwise (as you
face end of pipe) on all male threads being attached to
pump.
4. Tighten joints hand tight plus 1-1/2 turns. Do not over-
tighten.
NOTICE: Install pump as close to water source as possible.
Long piping runs and many fittings create friction and re-
duce flow.
Use schedule 80 or iron pipe. See “Well Pipe Installation” for
more information.

OPERATION
PRIMING THE PUMP
NOTICE: ‘Priming’ refers to the pump expelling all air in the
system and beginning to move water from its source out into
the system. It does not refer only to pouring water into the
pump (although pouring water in is usually the first step).
NOTICE: NEVER run pump dry. Running pump without
water in it will damage seals and can melt impeller and dif-
fuser. To prevent damage, fill pump with water before
starting.
1. Remove priming plug (Figure 7).
2. Make sure suction and discharge valves and any hoses on
discharge side of pump are open.
3. Fill pump and suction pipe with water.
4. Replace priming plug, using Teflon tape on thread;
tighten plug.
NOTICE: If a priming tee and plug have been provided
for a long horizontal run, be sure to fill suction pipe
through this tee and replace plug. (Don’t forget to Teflon
tape the plug.)
5. Start pump: water should be produced in 10 minutes or
less, the time depending on depth to water (not more
than 20’) and length of horizontal run (10’ of horizontal
suction pipe = 1’ of vertical lift due to friction losses in
the pipe).
If no water is produced within 10 minutes, stop pump,
release all pressure, remove priming plug, refill and try
again.
Hazardous pressure and risk of explo-
sion and scalding. If pump is run continuously at no
flow (that is, with discharge shut off or without prim-
ing), water may boil in pump and piping system.
Under steam pressure, pipes may rupture, blow off of
fittings or blow out of pump ports and scald anyone
near.
To prevent explosion, do the following:
A. Be sure discharge (valve, pistol grip hose nozzle, etc.) is
open whenever pump is running.
B. If pump fails to produce water when attempting to prime,
release all pressure, drain pump and refill with cold water
after every two attempts.
C. When priming, monitor pump and piping temperature. If
pump or piping begin to feel warm to the touch, shut off
pump and allow system to cool off. Release all pressure
in system and refill pump and piping with cold water.

MAINTENANCE
Pump and piping need not be disconnected to repair or re-
place motor or seal (see Figure 12). If motor is replaced, re-
place the shaft seal (Key No. 6, Page 11). Keep one on hand
for future use.
Be sure to prime pump before starting.
NOTICE: Check motor label for lubrication instructions.
The mechanical shaft seal in the pump is water lubricated
and self-adjusting.
NOTICE: Drain pump when disconnecting from service or
when it might freeze.
PUMP DISASSEMBLY
1. Disconnect power to motor.
NOTICE: Mark wires for correct assembly.
2. Remove clamp (see Figure 12).
3. Remove pump base mounting bolts. Motor assembly and
back half of pump can now be pulled away from pump
front half (Figure 12). CAREFULLY remove O-Ring.
CLEANING/REPLACING IMPELLER
NOTICE: First, follow instructions under “Pump Disassembly”.
1. Remove four screws fastening diffuser to seal plate; re-
move diffuser (see Figure 13). Exposed impeller can now
be cleaned.
2. If impeller must be replaced, loosen two machine screws
and remove motor canopy (see Figure 14).
3. Capacitor voltage may be hazardous.
To discharge capacitor, hold insulated handle screw-
driver BY THE HANDLE and short capacitor terminals
together (see Figure 14). Do not touch metal screwdriver
blade or capacitor terminals. If in doubt, consult a quali-
fied electrician.
4. Unscrew capacitor clamp and remove capacitor. Do not
disconnect capacitor wires to motor.
5. Slide 7/16” open end wrench in behind spring loaded
switch on motor end of shaft; hold motor shaft with
wrench on shaft flats and unscrew impeller by turning
counterclockwise when looking into eye of impeller.
6. To reinstall, reverse steps 1 through 5.
7. See directions under “Pump Reassembly,” Page 10.
REMOVING OLD SEAL
1. Follow instructions under “Pump Disassembly”.
2. Follow steps 2 through 5 under “Cleaning/Replacing
Impeller.
3. Unscrew four nuts holding pump back half to motor.
Remove rotating half of seal by placing two screwdrivers
under back half of pump body and carefully prying up
(Figure 15). Back half of pump body will slide off shaft,
bringing seal with it.
NOTICE: Be sure you do not scratch or mar shaft; if shaft is
marred, it must be dressed smooth with fine emery or cro-
cus cloth before installing new seal. DO NOT reduce shaft
diameter!

MAINTENANCE (Continued)
4. Place pump body half face down on flat surface and tap
out stationary half of seal (see Figure 16).
INSTALLING NEW SEAL
1. Wet outer edge of Rubber Cup on ceramic seat with liq-
uid soap. Be sparing!
2. Put clean cardboard washer on seal face. With thumb
pressure, press ceramic seal half firmly and squarely into
seal cavity in seal plate (see Figure 17). Polished face of
ceramic seat is up. If seal will not seat correctly, remove,
placing seal face up on bench. Reclean cavity. Seal should
now seat correctly.
3. If seal does not seat correctly after recleaning cavity, place
cardboard washer over polished seal face and carefully
press into place using a piece of standard 3/4” pipe as a
press.
NOTICE: Be sure you do not scratch seal face.
4. Dispose of cardboard washer and recheck seal face to be
sure it is free of dirt, foreign particles, scratches and
grease.
5. Inspect shaft to be sure it is free of nicks and scratches.
6. Reassemble pump body half to motor flange. BE SURE it
is right side up.
7. Apply liquid soap sparingly (one drop is sufficient) to in-
side diameter of rotating seal member.
8. Slide rotating seal member (carbon face first) onto shaft
until rubber drive ring hits shaft shoulder.
NOTICE: 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.
9. Hold motor shaft with 7/16” open end wrench on shaft
flats (Figure 14, Page 8) and screw impeller onto shaft. Be
sure you do not touch capacitor terminals with
body or any metal object. Tightening impeller will au-
tomatically locate seal in correct position.
