General Safety
Risk of explosion. The pump body may
explode if used to boost pressure above the maximum
pressure shown in Specifications. Do not use this pump
with inlet pressure greater than 70 psi (483 kPa). If not
already in the piping system, install a pressure relief
valve in the pump discharge line capable of passing the
full pump flow at maximum rated pressure. If local code
requires installation of a pressure relief valve capable
of handling the full pump flow at a pressure less than
100psi (689kPa), follow the code requirements.
Risk of fire or explosion. To avoid risk of
fire and explosion, Pump Water Only with this pump. Do
not pump salt water, flammable liquids or chemicals. Do
not use the pump near gas pilot lights or where chemical
or gas fumes are present. Use of an electric pump with
liquids other than water or in an atmosphere containing
chemical or gas fumes may ignite those liquids or
gases and cause injury or death due to an explosion
and/orfire.
Risk of burns. If water is trapped in the pump
during operation it may turn to steam. Trapped steam
can lead to an explosion and burns. Never run the pump
with the outlet closed or obstructed.
Risk of freezing. Do not allow pump, piping,
or any other system component containing water to
freeze. Freezing may damage system, leading to injury or
flooding. Allowing pump or system components to freeze
will void warranty.

Installation 5
Piping - General
Support both suction and discharge piping independently
at a point near the pump to avoid putting a strain on the
pump housing. Start all piping at the pump.
Increase pipe diameter at both the suction and discharge
by one (1) standard pipe size (minimum) to obtain
desired pressure and flow rate. Refer to Table I when
sizing pipe for your pumping system.
NOTICE: Do not use pipe with smaller diameter on the
suction side of pump.

Suction Pipe
Increase pipe size from pump tapping as shown in
TableI. Figure 1 depicts a recommended run of pipe and
fittings for the suction side of a centrifugal pump. Please
refer to this illustration when choosing pipe and fittings
for your suction connection.
NOTICE: All connections must be air tight!
Figure 2 depicts conditions that are not desirable on
the suction side of a centrifugal pump and may cause
problems in flow rate and priming. Please look this
illustration over carefully before choosing pipe and
fittings for your suction connection.
Discharge Piping
Increase pipe size from pump tapping as show in TableI.
Figure 1 depicts a recommended run of pipe and fittings
for the discharge. Install tee with priming plug as close to
pump as possible. Figure 2 depicts conditions that should
be avoided. Please examine carefully before making
discharge connection.
Priming The Pump
A pump is primed when all air in the suction line and
pump volute has been evacuated and replaced with water.
To prime pump:
1. Close valve in discharge line.
2. Remove priming plug from tee and fill pump and
suction line with water until water is flowing back
out of tee.
3. Replace priming plug.
4. Start pump and slowly open valve until desired water
flow is achieved.
NOTICE: If water is not being pumped, turn off
pump, close valve, and repeat steps 1 thru 4.
If pump volute is rotated as shown in Figure1, loosen
vent plug when priming to evacuate air trapped inside
volute. Tighten when volute is filled with water.
Risk of explosion and scalding. Never run
pump against closed discharge. To do so can boil water
inside pump, causing hazardous pressure buildup and
possible explosion.
Risk of burns. Motor normally operates
at high temperature and will be too hot to touch. It is
protected from heat damage during operation by an
automatic internal cutoff switch. Before handling pump
or motor, stop motor and allow it to cool for 20 minutes.
Risk of flooding. Do not run the pump dry.
This will damage mechanical seal and void warranty. It
may cause burns to person handling pump.

Wiring
Hazardous voltage. Can shock, burn, or
cause death. Disconnect power to motor before working
on pump or motor. Ground motor before connecting to
power supply.
• Ground motor before connecting to electrical power
supply. Failure to ground motor can cause severe or
fatal electrical shock hazard.
• Do not ground to a gas supply line.
Fire hazard. Incorrect voltage can cause
a fire or seriously damage the motor and voids the
warranty. The supply voltage must be within ±10% of the
motor nameplate voltage.
Wire three phase motors according to diagram on motor
nameplate. For any motor, use wire size specified in
TableII. Connect pump to a separate branch circuit with
no other appliances on it.
1. Install, ground, wire and maintain your pump in
compliance with the local electrical codes and
ordinances that apply. Consult your local building
inspector for code information.
2. Provide a correctly fused disconnect switch for
protection while working on motor. For switch
requirements, consult your local building inspector
for information about codes.
3. Disconnect power before servicing motor or pump.
If the disconnect switch is out of sight of pump,
lock it open and tag it to prevent unexpected
powerapplication.
4. Ground the pump permanently using a wire of the
gauge specified in Table II. Make ground connection
to green grounding terminal under motor canopy
marked GRD. or .
5. Connect ground wire to a ground bus in the service
panel or to a metal underground water pipe or well
casing at least 10 feet long. Do not connect to plastic
pipe or insulated fittings.
6. Protect current carrying and grounding conductors
from cuts, grease, heat, oil, and chemicals.
7. Motor has automatic internal thermal overload
protection. If motor has stopped for unknown
reasons, thermal overload may restart it
unexpectedly, which could cause injury or property
damage. Disconnect power before servicing motor.
8. If this procedure or the wiring diagrams are
confusing, consult a licensed electrician.Pump
Service
This centrifugal pump requires little or no service
other than reasonable care and periodic cleaning.
Occasionally, however, a shaft seal may become
damaged and must be replaced. The procedure as
outlined below will enable you to replace the seal.
NOTICE: Pumps use mechanical seals with a rubber
seat ring or a sealing O-Ring. These seals are completely
interchangeable.
NOTICE: The highly polished and lapped faces of this
seal are easily damaged. Read instructions and handle
the seal with care.
Some models are equipped with an impeller screw,
which has a left hand thread. Before unscrewing the
impeller, remove the impeller screw.
Removal of Old Seal
1. After unscrewing impeller, carefully remove rotating
part of seal by prying up on sealing washer, using
two screwdrivers (see Figure 5A). Use care to not
scratch motor shaft.
2. Remove seal plate from motor and place on flat
surface, face down. Use a screwdriver to push
ceramic seat out from seal cavity (see Figure 5B).
Installation of Floating Seat (Figure 5C)
1. Clean polished surface of floating seat with
cleancloth.
2. Turn seal plate over so seal cavity is up, clean
cavitythoroughly.
3. Lubricate outside rubber surface of ceramic seat with
soapy water and press firmly into seal cavity with
finger pressure. If seat will not locate properly in this
manner, place cardboard washer over polished face
of seat and press into seal cavity using a 3/4” socket
or 3/4” piece of standard pipe.
4. Dispose of cardboard washer. Be sure polished
surface of seat is free of dirt and has not been
damaged by insertion. Remove excess soapy water.

Maintenance 7
Installation of Rotating Part of Seal
Unit (Figure 5D)
1. Reinstall seal plate using extreme caution not to hit
ceramic portion of seal on motor shaft.
2. Inspect shaft to make sure that it is clean.
3. Clean face of sealing washer with clean cloth.
4. Lubricate inside diameter and outer face of rubber
drive ring with soapy water and slide assembly on
motor shaft (sealing face first) until rubber drive ring
hits shaft shoulder.
5. Screw impeller on shaft until impeller hub hits shaft
shoulder. This will automatically locate seal in place
and move the sealing washer face up against seat
facing. Reinstall impeller screw (if used).

Risk of electric shock. Can shock, burn or kill. To guard against accidental personal injury, the electric
power to the pump should be turned off when conducting the checking procedures outlined. There are obvious
exceptions, however, and service personnel should take necessary safeguards against the hazard of electrical shock.
Problem Probable Cause(s) Remedy
Pump fails to pump. Pump not properly primed. Make sure pump casing and suction line are
full of water. See priming instructions.
Pump has reduced
capacity and/or head.
Air pockets or leaks in suction line. Check suction piping.
Clogged impeller. Remove and clean.
Pump loses prime.
Air leaks in suction line. Check suction piping.
Excessive suction lift and operating too near
shut-off point. Move pump nearer to water level.
Water level drops while pumping,
uncovering suction piping.
Check water supply. Add length of pipe to
suction to keep submerged end under water.
Mechanical troubles
and noise.
Bent shaft and/or damaged bearings. Take motor to authorized motor repair shop.
Suction and/or discharge piping not properly
supported and anchored.
See that all piping is supported to relieve
strain on pump assembly.
