BEFORE YOU INSTALL YOUR PUMP
NOTE: For proper performance, pump MUST be matched to ejector and
to well depth. Use shallow well installation for wells up to 25 ft depth to
water and deep well ejector for depths up to 130 ft.
Step 1. Long runs and many fittings increase friction and reduce flow.
Locate pump as close to well as possible: use as few elbows and
fittings as possible.
Step 2. Be sure well is clear of sand. Sand will plug the pump and void the
warranty.
Step 3. Protect pump and all piping from freezing. Freezing will split pipe,
damage pump and void the warranty. Check locally for frost pro-
tection requirements (usually pipe must by 12” below frost line and
pump must be insulated).
Step 4. Be sure all pipes and foot valve are clean and in good shape.
Step 5. No air pockets in suction pipe.
Step 6. No leaks in suction pipe. Use PTFE pipe thread sealant tape to seal
pipe joints.
Step 7. Match pump to well.
IMPORTANT: Flow into well must at least equal flow out through
pump!
Step 8. Unions installed near pump and well will aid in servicing. Leave
room to use wrenches.
Step 9. Plug 1” drive port when installing on shallow well.
SHALLOW WELL/CENTRIFUGAL INSTALLATION
No ejector is used in this case, plug the smaller of the two inlet ports,
using the larger for the suction pipe. Refer to Figure 6 for installation tips.
Maximum depth to water for shallow well/centrifugal operation is 25 feet.
NOTE: To avoid pump overloading and motor failure, install a flow control
valve at the discharge to limit flow to 20 gallons per minute.

PIPING IN THE DEEP WELL
See Figures 7 and 8.
NOTE: Deep well installations are either single pipe (2” wells) or double
pipe (4” and larger wells). In a double pipe installation, the larger pipe is
the suction pipe and the smaller pipe is the drive pipe (very deep wells
may use suction and drive pipes of the same diameter).
Plastic pipe is ideal for double pipe installations. Due to its light weight, it
is easy to handle and does not usually require a block and tackle for instal-
lation and removal.
PLASTIC PIPE INSTALLATION – DOUBLE PIPE
NOTE: Use PTFE pipe thread sealant tape on all male threads on plastic
pipe and fittings to prevent air leaks in suction piping.
Step 1. Inspect ejector to make sure that nozzle and venturi openings are
clean and clear.
Step 2. Inspect pipe for any foreign matter or obstructions.
IMPORTANT: Make sure that no foreign matter enters pipe open-
ings while installing pump.
Step 3. Make sure foot valve operates freely: attach to ejector with a close
nipple. Use PTFE pipe thread sealant tape on male threads.
Step 4. Install nozzle and venturi in deep well ejector.
Step 5. Using PTFE pipe thread sealant tape on male threads, install spe-
cial plastic pipe adapter (supplied with ejector) by screwing adapt-
er into 1-1/4” tapped hole in ejector body (see Figure 7A).
Step 6. Thread a 1” plastic pipe adapter into the 1” tapped hole in ejector
body (see Figure 7A).
Step 7. Install sufficient plastic pipe in well casing to place ejector at the
proper depth. (Your well driller should supply this information.)
IMPORTANT: as a guide, the ejector should be set at least 10 to
20 feet below the lowest water level with pump running, if possi-
ble, but always at least five feet from the bottom of the well.
Step 8. Tighten all hose clamps securely on plastic pipe. Use two clamps
per joint to prevent air leaks into suction pipe. Clamp screws
should be on opposite sides of the pipe. Fill pipes with water to
make sure that foot valve and connections do not leak.
Step 9. Install sanitary well seal on top of well casing; use steel nipple
through well seal as shown in Figure 7A.
IMPORTANT: align locating lugs on adapter flange and pump
base so that pump discharge will be aligned with piping.
Step 10. Install 1” nipple in one side of adapter flange. Slide threadless
coupling down over drive pipe from well. Thread adapter flange
onto suction pipe from well and align nipple and drive pipe.
Step 11. Slide threadless coupling up and secure nipple to drive pipe.
Step 12. Remove paper backing from adhesive gasket. Apply gasket to
adapter flange, making sure that holes line up.
Step 13. Align locating lugs on pump base with locating lugs on adapter
flange; attach pump to flange with cap screws provided.
Step 14. See “Discharge Pipe Sizes” for information regarding correct dis-
charge pipe size.

SINGLE PIPE EJECTOR INSTALLATION
Single pipe installations require (see Figure 8):
a. Galvanized steel pipe
b. Leather packer-type ejector with built-in foot valve
c. Turned couplings (supplied with packer-type ejector)
d. Well casing adapter.
Step 1. Connect ejector to first length of pipe. Use pipe joint compound
sparingly on male threads.
Step 2. Lower pipe into casing. Use special turned couplings (included
with 2” single pipe ejector package) to increase water flow. Use
pipe joint compound sparingly on male couplings threads.
NOTE: Fill pipe with water as each length is added to be sure foot valve
and connections do not leak.
Step 3. Add lengths of pipe until the ejector reaches the proper depth.
(Your well driller should supply this information.)
IMPORTANT: as a guide, the ejector should be set at least 10 to 20 feet
below the lowest water level with pump running, if possible, but always at
least 5 feet above the bottom of the well (see Figure 8).
Step 4. To properly seat the cup seals, after the ejector is correctly posi-
tioned move the assembly up and down slightly. Water pressure in
the casing will then soak the cup seals (see Figure 8). They should
seal within 2-3 hours after installation.
Step 5. With ejector set, install well casing adapter. Remove pipe holder.
Align locating lugs and tighten adapter to form seal with well
casing.
DISCHARGE PIPE SIZES
Step 1. If increasing discharge pipe size, install reducer in pump discharge
port. Do not increase pipe size by stages.
Step 2. When the pump is set away from the points of water use, the dis-
charge pipe size should be increased to reduce pressure losses
caused by friction.

PRESSURE TANK INSTALLATION – DEEP WELL
The Pressure Tank provides a reservoir of water under pressure and main-
tains cushion of air pressure to prevent pipe hammering and possible
damage to plumbing components. When water is drawn off through house
fixtures, the pressure in the tank is lowered and the pressure switch starts
the pump.
STANDARD TANK CONNECTION
When a standard tank is used, an air volume control (AVC) adds air to the
tank when it is needed. See Figure 10 for typical standard tank installation.
To connect AVC to pump, thread a 1/4” compression fitting into tapped
hole on the front of the pump. Cut tubing to length to reach AVC; assemble
to fitting on pump and to AVC on tank. See installation instructions provid-
ed with tank and AVC for details.
PRECHARGED TANK CONNECTION
When a precharged tank is used, no AVC is necessary. See Figure 10 for
typical precharged tank installation. A precharged tank contains a factory
provided air charge.
IMPORTANT: your pump pressure switch is set for a 30-50 PSI range and
requires a tank pre-charge of 28 PSI for proper operation (see Figure 11). See
tank owner’s air charge. An annual check on tank charge is recommended.

Connection Procedure:
Step 1. Connect the ground wire first as shown in Figure 12. The ground
wire must be a solid copper wire at least as large as the power sup-
ply wires.
Step 2. There must be a solid metal connection between the pressure
switch and the motor for motor grounding protection. If the pres-
sure switch is not connected to the motor, connect the green
ground screw in the switch to the green ground screw under the
motor end cover with a solid copper wire at least as large as the
power supply wires.
Step 3. Connect the ground wire to a grounded lead in a service panel,
to a metal underground water pipe, to a metal well casing at least
ten feet (3M) long, or to a ground electrode provided by the power
company or the hydro authority.
Step 4. Connect the power supply wires to the pressure switch as shown in
Figure 12.

Operation 10
PRIMING THE PUMP
NEVER run pump dry. Running pump without water may cause
pump to overheat, damaging seal and possibly causing burns to per-
sons handling pump. Fill pump with water before starting.
NEVER run pump against closed discharge, to do so can boil
water inside pump, causing hazardous pressure in unit and possibly scald-
ing persons handling pump.
NOTE: Open water system faucets before priming pump for the first time.
Step 1. Remove pressure gauge.
a. Close pressure regulator (turn clockwise - see Figure 13).
b. Fill pump and suction pipe with water (Figure 13).
c. Replace pressure gauge, using PTFE pipe thread sealant tape on
thread; tighten gauge.
IMPORTANT: If a priming tee and plug have been provided for a long hor-
izontal run, be sure to fill suction pipe through this tee and replace plug.
(Don’t forget to PTFE pipe thread sealant tape the plug.)
Step 2. Start Pump:
Pressure should build rapidly to 50 pounds per square inch or more
as ejector and pump prime.
IF NO PRESSURE OR NO WATER, REPEAT Step No. 1 (above) two or three
times to remove entrapped air from the suction pipes.
Step 3. If, after priming pump several times, no water is pumped, check the
following:
a. Suction pipe in the water and has no leaks.
NOTE: Air can leak in even where water won’t leak out. Make
sure all joints are tight.
b. Pressure regulator, check valve, or foot valve installed and oper-
ating correctly.
c. Pump trying to lift water more than 25 feet (shallow well) or
more than rated lift for deep well ejector used (including com-
pensation for horizontal offset).
d. Be sure pump is not airlocked. In offset installations, pump suc-
tion port should be highest point in suction pipe; there should
be no sags in suction pipe (run it straight and at a slight angle
upward from well head to pump).
NOTE: For deep well installation, go to Step 4 (Page 11). Shallow well
installations go to Step 6 (Page 11).

Operation 11
Step 4. Once unit has primed and pressure stabilized, slowly open (turn
counterclockwise - Figure 14A) regulator valve until pressure fal-
ters (pressure gauge needle flutters; pump may become noisy - see
Figure 14B). At this point, close (turn clockwise) regulator valve
slightly until pressure stabilizes. This setting provides maximum
flow (Figure 14C).
Step 5. Pump may draw well down far enough at this point to lose its
prime. If so, close regulator valve until pressure is stable throughout
pumping cycle. Close faucets and allow pump to pressurize tank
and shut off.
Step 6. Check system by alternately opening and closing faucets in the sys-
tem. With faucets open , pressure will drop until pump starts; with
faucets closed, pressure will build up until pump shuts off.
Step 7. There are conditions of deep well operation when the regulator
valve may be completely open without any faltering of pressure. In
this case, operate pump with regulator valve open.
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 that it surrounds the suction pipe
inlet. (See Figure 15). Since the gases rise in the well casing, the water
sucked down through the pipe and into the pump suction is free of gas.
This type of well must be vented to the outside of any enclosure.
AIR CONTROL IN FLOWING WELLS
Flowing wells or wells with little or no drawdown, could create a special
problem in air control in the operation of your standard tank system.
In such cases, a pre-charged tank (which needs no air control) is
recommended.

Maintenance 12
PUMP DISASSEMBLY/ASSEMBLY
Step 1. Turn off power at disconnect switch. Disconnect power lines from
pressure switch.
Step 2. Remove the two cap screws holding the pump to the flange adapt-
er. Don’t disturb the piping in the well.
Step 3. Remove the adapter flange gasket and scrape the surfaces clean.
Step 4. Unscrew and remove the straight barbed fitting at the pressure
switch.
Step 5. Draw a line down the side of the pump with a marker to help
alignment during reassembly. Mark the pump from the motor to
the base volute (see Figure 16).
Step 6. Turn the pump upside down on the bench and block it. Remove
the four cap screws from the base. With a mallet, tap upward on
the base to loosen it. Lift the base off of the intermediate volute
(see Figure 17).
Step 7. To reduce the chance of dropping the pump onto your foot, lay it
down on the bench; block it so it won’t roll.
Step 8. Hold the motor shaft with pliers or vice grips through the opening
in the pump adapter. Unscrew the impeller nut off the end of the
shaft (see Figure 18).
Step 9. The impellers are keyed to the shaft and do not unscrew. Insert
two screw drivers on opposite sides under the exposed impeller
and pry the impeller off (Figure 19) to remove it.
Step 10. Carefully tap a small screwdriver or thin bladed chisel in between
the intermediate volute and the pump adapter in two or three
places around the pump to separate the castings (Figure 20). Do
not mar the sealing surfaces; do not break pieces out of the adapt-
er or volute – the castings are easily damaged.
Step 11. Remove the intermediate volute and slide the impeller spacer off
of the shaft.
Step 12. Remove the impeller. Don’t disturb the shaft keys if you are only
replacing the seal.
Step 13. Rotate the seal spring retainer cup so that the slot lines up with
the shaft keys; remove the cup and spring.
Step 14. Remove the two cap screws holding the adapter bracket to the
motor.
Step 15. With two screwdrivers on opposite sides of the pump, carefully pry
the pump adapter away from the motor. This will pull the seal off
of the motor shaft. Use caution to make sure that the ceramic seal
does not dig into the shaft and scratch the shaft’s sealing surface.
INSTALLATION OF NEW SEAL
Step 1. Clean all gasket surfaces thoroughly before reassembly. Clean the
seal bore cavity in the pump adapter.
Step 2. Wet the rubber seat ring with soapy water and push the stationary
part of the seal into the seal bore cavity. Use a piece of 1” pipe
pressing on a cardboard washer (to prevent damaging seal surface)
as a press. Make sure that the seal half is fully seated in the seal
bore cavity. Remove the cardboard once the seal is in place.

Maintenance 13
Step 3. Make sure that the shaft keys are in place on the shaft. If they are
not, squeeze them in place now with slip joint pliers. Do not tap
them or hit them with a hammer; you could bend the shaft (see
Figure 21). When the keys are correctly installed, the adapter will
pass over the keys without interference.
Step 4. Carefully slide the adapter over the shaft (see Figure 22). Do not
damage the shaft sealing surface; it is highly polished and any
slight scratches or nicks will ruin it.
Step 5. Using the alignment marks made before disassembly, line up the
adapter with the motor and bolt the adapter in place. Tighten the
cap screws evenly.
Step 6. Push the shaft seal and seal spring onto the shaft, after making
sure that the seal faces and shaft are clean. Take care that the
shaft shoulder does not damage the carbon seal face. Follow the
seal spring with the spring holder; compress the spring and give
the spring holder a quarter turn to lock it under the first shaft key
(see Figure 23).
Step 7. Slide the first impeller onto the shaft; follow it with the impeller
spacer. Twist the impeller on the shaft to make sure that the shaft
key is still in place and the impeller is locked to the shaft (the
shaft should turn with the impeller).
Step 8. Install a new volute gasket, lining up the bolt holes with the bolt
holes in the adapter. Make sure the gasket is right side up so that
the water passage holes line up with the water passages in the
volutes.
Step 9. Install the intermediate volute, aligning it with the mark made
before disassembly. Use the long cap screws to check this align-
ment. It cannot be stressed too strongly that all bolt holes and
water passages of all gaskets and volutes MUST line up with each
other, or the pump will not be assembled correctly.
Step 10. Make sure the second shaft key is in place and install the second
impeller. Twist the impeller to make sure that the shaft key is still
in place. Hold the motor shaft with slip-joint pliers or vice-grips
and install and tighten the impeller locknut. Tightening the lock nut
automatically spaces the impeller correctly. Do not overtighten.
Step 11. Install the base volute gasket. Make sure the gasket is right side up
so that the water passage holes line up with the water passages
in the volutes. Install the base volute, using the alignment marks
made before disassembly. Make sure that the pump discharge will
correctly meet the the piping when the pump is reinstalled.
Step 12. Insert the four base capscrews and tighten evenly (see Figure 24).
These should be easy to install if everything is correctly aligned. If
not, don’t force them; go back over your work and find and cor-
rect the misalignment.
Step 13. Reinstall the pressure switch barbed fitting and pressure tube.
Step 14. Reinstall the pump on the adapter flange (use a new gasket) and
reconnect the wiring and grounding. Pump is now ready for
operation.
Use pliers –
with care –
no hammers.

AVANT D’INSTALLER LA POMPE
REMARQUE : Pour obtenir un bon rendement de la pompe, elle DOIT être appar-
eillée à l’éjecteur et à la profondeur du puits. Se reporter à la rubrique «Installation
sur un puits peu profond» dans le cas des puits dont la surface libre maximum
jusqu’à l’eau est de 7,60 mètres (25 pieds) et à «Éjecteur pour puits
profonds» si la surface libre maximum jusqu’à l’eau est de 40mètres (130 pieds).
1° De grandes longueurs de tuyaux et de nombreux raccords augmentent le
frottement et réduisent le débit. Positionner la pompe aussi près que possible
du puits. Utiliser le moins possible de coudes et de raccords.
2° S’assurer que le puits est débarrassé de sable. La garantie sera annulée si du
sable bouche la pompe.
3° Protéger la pompe et toutes les tuyauteries contre le gel. Le gel fera éclater les
tuyauteries, endommagera la pompe et la garantie sera annulée. Vérifier quelles
sont les conditions locales requises pour protéger l’ensemble de ce système
contre le gel (habituellement, les tuyaux doivent être enterrés à 30 cm
(12 pouces) plus profond que la profondeur de gélivation maximum et la
pompe doit être isolée).
4° S’assurer que toutes les tuyauteries et que le clapet de pied sont propres et en
bon état.
5° Il ne doit y avoir aucune poche d’air dans le tuyau d’aspiration.
6° Il ne doit y avoir aucune prise d’air dans le tuyau d’aspiration. Utiliser du ruban
d’étanchéité en PTFE pour filetage ou de la pâte en bâtonnet pour rendres
étanches les joins des tuyaux.
7° Appareiller la pompe au puits.
IMPORTANT: Le débit de l’eau alimentant le puits doit être au moins égal au
débit de la pompe!
8° Des raccords unions installés près de la pompe et du puits faciliteront l’entre-
tien de la pompe. Prévoir suffisamment d’espace pour pouvoir utiliser des clés à
tuyau.
9° Boucher l’orifice d’eau motrice de 1 po si cette pompe est installée sur un puits
peu profond.
INSTALLATION SUR UN PUITS PEU PROFOND OU
UTILISATION EN TANT QUE POMPE CENTRIFUGE
Dans ce cas, on n’utilise pas d’éjecteur. Boucher le plus petit des deux orifices
d’admission et utiliser l’orifice de plus grand diamètre pour le tuyau d’aspiration.
Se reporter à la Figure 6 pour des conseils relatifs à l’installation. Si cette pompe
est installée sur un puits peu profond ou si elle est utilisée en tant que pompe
centrifuge, la surface libre jusqu’à l’eau doit être de 7,60 mètres (25 pieds).
REMARQUE: Pour ne pas surcharger la pompe et empêcher une panne du moteur,
poser un robinet de limitation de débit sur le tuyau de refoulement de façon à
limiter le débit de la pompe à 75 litres par minute (20 gallons par minute).
