Safety Precautions
WARNING: READ THIS MANUAL COMPLETELY BEFORE INSTALLING AND OPERATING THIS UNIT. FAIL-
URE TO FOLLOW THESE PRECAUTIONS CAN RESULT IN SERIOUS INJURY OR DEATH.
WARNING: Magnetic eld hazard. This pump contains powerful magnets. Exposed magnets (pump not connected
to motor) produce powerful magnetic elds. Individuals with cardiac pacemakers, implanted debrillators, other elec-
tronic medical devices, metallic prosthetic heart valves, internal wound clips (from surgery), metallic prosthetic devices or
sickle cell anemia must not handle or be in the proximity of the magnets contained inside the pump. Consult a health care
provider for specic recommendations before working with this pump.
WARNING: Magnetic force hazard. This pump should only be disassembled and assembled using the recommend-
ed procedures. The magnetic attraction is powerful enough to rapidly pull the motor end and the wet end together. Do not
place ngers between the mating surfaces of the motor and wet ends to avoid injuries. Keep the drive magnet and impeller
assembly away from metal chips or particles, items with magnetic stripes like credit cards, and magnetic computer media
such as oppy discs and hard drives.
WARNING: Not Recommended for Pumping Flammable or Combustible Liquids. During the priming process the
internal pump atmosphere can become very dangerous should the pump fail to prime and overheat.
The SP Series pumps can be used to pump non-ammable or non-combustible liquids in a hazardous area. It is important
to follow these guidelines:
1. Select the Ns (non-sparking) bronze bump ring option. The non-sparking ring is pressed into the clamp ring or motor
adapter and prevents sparking should the motor bearings fail and the outer mag drive assembly runs out of round.
2. Select an FTI explosionproof motor or provide your own.
WARNING: Hot surfaces. This pump is capable of handling liquids with temperatures as high as 220º F (104º C).
This may cause the outer areas of the pump to become hot as well and could cause burns.
WARNING: Rotating Parts. This pump has components that rotate while in operation. Follow local safety standards
for locking out the motor from the power supply during maintenance or service.
WARNING: Chemical Hazard. This pump is used for transferring many types of potentially dangerous chemicals.
Always wear protective clothing and eye protection, and follow standard safety procedures when handling corrosive or
personally harmful materials. Proper procedures should be followed for draining and decontaminating the pump before
disassembly and inspection of the pump. There may be small quantities of chemicals present during inspection.
WARNING: Never run pump at less than minimum ow or with the discharge valve closed. This could lead to pump
failure.
3
WARNING: The pump and associated components are heavy. Failure to properly support the pump during lifting and
movement could result in serious injury or damage to the pump and components.
CAUTION: This pump should never be started without the 0.6 US gallon /77 oz. ( 2.7 liters) of priming uid in the
housing. If the pump has a PTFE, ceramic or silicon carbide bushing, IT CANNOT BE RUN DRY WITHOUT CAUSING
DAMAGE TO THE PUMP. However, the pump can operate without liquid in the housing if the pump has a carbon bushing.
The exact length of time the pump can operate dry with a carbon bushing varies with operating conditions and environment.
CAUTION: Never start or operate with a closed suction valve.
WARNING: Operation without priming or against a closed discharge valve can result in high temperatures that can
result in injury or damage to pump components.
CAUTION: Always provide adequate NPSHa (net positive suction head available). It is recommended to provide at
least 2 feet (61 cm) above the NPSHr (net positive suction head required).
CAUTION: If pump is used on variable speed drive, do not exceed 60 Hz.

sembly. With the motor/outer drive magnet assembly in
a horizontal position, securely clamp to the workbench.
NOTE: If the pump has the optional o-ring sealing op
tion (available on 56C and 145TC frame pumps only),
in stall the o-ring (item 16) in the groove in the motor
adapter (motor end).
Carefully slide the pump onto the drive magnet as sembly. The last couple of inches (5 cm) before the
pump reaches the motor will have STRONG magnetic
attraction between the pump and outer drive magnet

CAUTION: The NPSH available to the pump must be
greater than the NPSH required. The amount of lift,
frictional pipe loss, and vapor pressure must be calcu lated into the application. NPSH available should be 2
feet (.6 meters) greater than NPSH required.
• Total suction lift including pipe friction loss and
corrections for specic gravity must not exceed value
shown in chart below.

NOTE Maximum suction lift is reduced by 1.13 feet
(.34 meters) for every 1,000 feet (304 meeters) of
altitude.
• Install the pump as close to the suction source as
possible.
• SP Series pumps are designed to operate in a horizontal
position only with discharge on the top.
• SP Series pumps self-priming capability is due to its
ability to create a vacuum in the suction piping. The
suction piping MUST be airtight at ttings and
connections.
• Support the piping independently near the pump to
eliminate any strain on the pump casing. In addition,
the piping should be aligned to avoid placing stress on
the pump casing.
• The suction side of the pump should be as straight and
short as possible to minimize pipe friction.
• The suction line should not have any high spots. This
can create air pockets that can reduce pump perfor mance. The suction piping should be level or slope
slightly upward to the pump.
• The suction pipe should be 1” (25.4 mm) or 1½” (38
mm). Larger suction piping will affect priming ability.
Smaller piping affects NPSH available and pump per formance. See SP10 performance curve book or on-line
at www.nishthompson.com.
• Provide for adequate suction submergence. Excessive
submergence will reduce pump performance.
• The end of the pipe should be at least 2” (5.08 cm) for
1” pipe & 3” (7.6 cm) for 1½” pipe above the bottom
of the suction tank.
• If debris is in the suction tank, a strainer can be in stalled to help prevent foreign matter from entering
the pump. The strainer must be periodically cleaned to
prevent restriction.
• It is recommended that a vacuum/pressure gage be
installed in the suction piping.
• For faster priming on installations with high lift, a foot
valve is recommended.
• Check and control valves (if used) should be installed
on the discharge line. The control valve is used for
regulating ow. Isolation valves on the suction and
discharge are used to make the pump accessible for
maintenance. The check valve helps protect the pump
against damage from water hammer. This is particularly
important when the static discharge head is high.
NOTE: If a check valve is used in the discharge line, it
must be placed at a distance at least equal to the maxi mum suction lift from the pump. If this cannot be done,
an air vent must be provided in the discharge line.
• If exible hose is preferred over pipe, use a vacuum
rated reinforced hose for the proper temperature, pres sure and is chemically resistant against the uid being
pumped.
• The suction valve must be completely open to avoid
restricting the suction ow.
• When installing pumps with anges, we recommend
use of low seating stress gaskets such as Gore-Tex or
Gylon (expanded PTFE).
• It is advisable to install a ush system in the piping to
allow the pump to be ushed before the pump is re moved from service.
NOTE: The pump is provided with a 1/2” BSPP drain
in the impeller housing.
• A “tee” can be installed in the discharge piping as an
alternative location for lling the housing with uid
before pump operation.
• “Filling” is dened as lling the housing with 0.6 US
gallon / 77 oz. (2.7 liters) of liquid
• “Priming” is dened as evacuating all the air from the
suction piping/pump and replacing it with uid. See
Priming chart on next page.

Motor/Electrical
Install the motor according to NEC requirements and local
electrical codes. The motor should have an overload protec-
tion circuit.
Wire the motor for clockwise rotation when facing the fan
end of the motor.
CAUTION: Do not operate the pump to check rotation
until the pump is full of liquid.
Check all electrical connections with the wiring diagram
on the motor. Make sure the voltage, frequency, phase, and
amp draw comply with the supply circuit.
To verify correct rotation of the motor:
1. Install the pump into the system.
2. Remove the ll plug (items 2 & 2A) and ll the hous -
ing with 0.6 US gallon / 77 oz. (2.7 liters) of the service
liquid or water. Replace ll plug and tighten until the
o-ring is seated.
NOTE: Use a exible spout funnel or a “tee” in the
discharge piping to ll the housing on pumps equipped
with anges.
3. Fully open the suction and discharge valves.
4. Jog the motor (allow it to run for 1-2 seconds) and ob serve the rotation of the motor fan. Refer to the direc tional arrow molded into the front of the housing if
necessary.
NOTE: An SP pump running backwards may not
prime.
Section III - Start-up and Operation
2. Open the inlet (suction) and outlet (discharge) valves
completely.
3. Turn the pump on. Wait for discharge pressure and ow
to stabilize (could take several minutes depending
upon suction lift). Adjust the ow rate and pressure by
regulating the discharge valve. Do not attempt to adjust
the ow with the suction valve.
Section IV - Shutdown
Turn off the motor.
NOTE: When the pump is stopped without a check valve
in the piping, liquid will ow through the pump returning
to the suction source. The SP design allows enough liquid
to be retained in the housing to allow repriming without
having to rell with liquid.
Flush Systems
CAUTION: Some uids react with water; use compat-
ible ushing uid.
1. Turn off the pump.
2. Completely close the suction and discharge valves.
3. Connect ushing uid supply to ush inlet valve.
4. Connect ushing uid drain to ush drain valve.
5. Open ushing inlet and outlet valves. Flush system
until the pump is clean.
NOTE: The drain can be used as the ushing drain
valve using appropriate customer supplied ttings. Us ing the drain helps to promote superior ushing and
draining results.
1. Be sure the housing (item 1) has been lled with 0.6
US gallon / 77 oz. (2.7 liters) of service liquid and the
ll plug (item 2 & 2A) has been installed and tightened
until the o-ring is seated.

Maintenance
Recommended maintenance schedule
The recommended maintenance schedule depends upon the
nature of the uid being pumped and the specic applica-
tion. If the pump is used on a clean uid, it is recommended
that the pump be removed from service and examined after
six months of operation or after 2,000 hours of operation.
If the pump is used on uids with solids, high temperatures
or other items that could cause accelerated wear, this initial
examination should be sooner.
After the initial examination of the internal components and
wear items are measured, a specic maintenance schedule
can be determined. For best results, it is recommended that
the pump be removed from service annually for examination.

the barrier and adaptor so t may be snug. See gure
21. Inspect the inside and outside of the barrier for
signs of rubbing.
Figure 21
Thrust Ring Replacement
1. The thrust ring (item 8A) is held in-place with a snap t
with a ridge. Using a razor, knife, or side cutters, cut
a notch out of the thrust ring. Pull ring up and out of
the holder. See gures 23 & 24.
13. Remove the o-ring (item 4) from the barrier and inspect
for chemical attack, swelling, brittleness, cuts, etc.
14. Visually inspect the outer drive (item 17) for rubbing,
damage, corrosion, or loose magnets.
Outer Drive Replacement
1. Remove the setscrews (item 17B) from the side of the
drive (NEMA motors) or the bolt, lock washer and at
washer (items 25, 26 & 27) from the center of the drive
(metric motors).
WARNING: Be careful, tools will want to be attracted
to the magnets.
2. Remove the drive magnet from the motor shaft by gen-
tly prying up from the bottom of the drive. See gure 22.
3. To reinstall the drive or a new drive, follow the instruc-
Figure 23
Figure 24
2. To reinstall, align the two ats on the thrust ring with
the ats in the bore of the impeller. Using a piece of
wood, press into place using an arbor press until the
thrust ring is completely seated in the impeller.
Bushing Replacement
To remove the bushing, place the impeller/inner drive as-
sembly in an arbor press. Insert a 7/16” diameter plastic or
wood shaft through the eye of the impeller and press the
bushing out.
To replace the bushing (item 9A), place the top of the
impeller on an arbor press with the thrust ring face down.
Insert the front of the bushing (see gure 25) into the center
of the impeller/inner drive magnet assembly. Press into
place until the bushing reaches the shoulder molded into
the inner drive. See gures 26 & 27.

Impeller Replacement
To remove the impeller from the inner drive magnet, gently
pry off by hand or lightly
tap on the back of the im-
peller. See gure 28.
To install a new impel-
ler, place the inner drive
magnet assembly face up.
Line up the patterns on the
impeller with the ones on
the inner drive magnet so
Figure 28
they match and press into place by hand. An arbor press can
also be used to press the impeller on the inner drive. Place
a piece of wood over the top of the impeller thrust ring and
push down on the impeller until it is completely seated in
the inner drive.
4. Install barrier into motor adapter/clamp ring assembly.
NOTE: If removed, reinstall the o-ring (item 12), lubri-
cate with a chemically compatible lubricant, and install
in the groove in the clamp ring before installing the
barrier. See gure 33A. Lubricate the back of the bar-
rier with a chemically compatible lubricant and push it
straight down into place. See gure 33B. Note: Barrier
can only be installed in one position. The barrier prongs
should be placed in the 11:00, 2:00 and 5:00 o’clock
positions. See gure 33 for correct orientation. Line up
the 5:00 o’clock prong with the bottom bolt hole in the
motor adapter. See gure 33C.
Section VI Reassembly
1. Place motor adapter (item 15)
so the large ange is on the
bench. Rotate the adapter so
the four holes in the smaller
ange are in the horizontal
position. See gure 29. If re moved, reinstall the o-ring
(item 14) in the groove on the
face of the motor adapter.
Lubricate the o-ring with chemically compatible lubri cant. This will help to hold it in place. See gure 29.
2. Install clamp ring. Note: The discharge tting must
be in the vertical position for all SP series pumps to
work properly – Install the clamp ring (item 13) on the
motor adapter so NO clamp ring bolt holes are in 12:00
or 6:00 position (see gure 30). Align the (4) bolt holes
with the bolt holes in the motor adapter & push straight
down. This will properly seat the o-ring to prevent
vapors from entering this area during pump operation.
3. Install (4) at washers, lock washers and M8 bolts
(items 22, 23, 24). Tighten evenly using a star pattern.
Tighten to 60 in-lbs (6.8 N-m). See gure 31.

5. Install o-ring (item 4) in groove in the barrier making
sure it is tucked in all the way around.
6. Install impeller shaft (item 10) into barrier by aligning
the ats on the shaft with the ones in the barrier. Make
sure it is completely seated.
7. Carefully install the impeller/inner drive assembly
(items 8, 8A, 9 & 9A) by sliding it over the impeller
shaft in the barrier. It is normal for the impeller/inner
drive to pop up a slight amount due to magnetic forces
with the metal clamp ring. See gures 34 & 35.

9. Install the separator plate (item 6) by lining up the
bottom opening of the inner volute with the opening in
the plate. Line up the slots in the separator plate with
the notches in the inner volute. See gure 38.
10. If the inner volute o-ring was removed previously,
lubricate the inner volute o-ring (item 5) with a chemi-
cally compatible lubricant, and install it in the groove
on the round suction nozzle in the center of the inner
volute. See gure 39.
8. Install the inner volute (item 7) by lining up the prongs
of the barrier with the channels in the inner volute.
Press down evenly until the prongs snap onto the sur-
face of the inner volute. See gures 36 and 37.

11. After lubricating inside of gooseneck, install the hous ing (item 1). Line up the tab on the top of the separator
plate with the notch in the housing (located inside the
front of the housing near the discharge port). Using uni
form pressure, press the housing into place until it is
ush with the motor adapter. See gure 40. Install the
housing bolts, lock washers and at washers (items 19,
20 & 21). Tighten all bolts evenly using a star pattern.
Tighten to 5 foot-lbs (6.8 N-m). Note: If bolt holes do
not line up, it may be necessary to tap the housing into
place with a rubber mallet. If still unable to line up the
bolt holes, then disassemble the pump down to the
barrier and start over from step 4.

Section Vii - Troubleshooting
General Notes:
• Cold water can contain dissolved air. Under high lift ap plications, the air can come out of solution blocking
suction passages. This can lead to lack of priming, slow
priming, or low ow rates.
• Do not pump liquids containing ferrous metal nes.
• If magnets decouple, stop pump immediately. Operat ing the pump with the magnets decoupled will eventu-
ally weaken the magnets.
• Do not use mismatched drive magnet assemblies (dif ferent number of magnets on inner and outer drive mag-
net assemblies).
• Contact our Technical Service Department by phone at
800-888-3743 or by e-mail at techservice@nishthomp-
son.com if you have any questions regarding product
operation or repair.
No or Insufcient Discharge
• Air leaks in suction piping
• Housing not lled with priming uid
• Suction pipe smaller than 1”
• Suction pipe contains high spots causing trapped air
pockets
• Suction pipe excessively long (ow drops as suction
pipe gets longer)
• System head higher than anticipated
• Closed valve
• Viscosity or specic gravity too high
• Motor too large for magnet coupling rating (magnets
uncoupled)
• Clogged suction line, suction strainer (if used), or impel-
ler vanes
Insufcient Pressure
• Air or gas entrained liquid
• Impeller diameter too small
• System head lower than anticipated
• Motors speed insufcient (too low) or motor rotation
incorrect (correct rotation when viewed from the fan end
is clockwise)
Won’t Prime
• Did not ll housing with uid before initially starting
pump
• Closed discharge valve (valve should be open or open air
vent line)
• Leak in suction piping
• Suction pipe not submerged enough (causing a vortex or
exposing the end of the suction pipe)
• Lift exceeds pump ability (see Capabilities section)
• Suction pipe diameter too large
• Specic gravity or local atmospheric pressure (altitude/
elevation) not accounted for in lift calculations
• Mis-match of inner volute and impeller diameter
• Inner volute o-ring chemically attacked, cut, brittle, etc.
• Motor rotation incorrect (correct rotation when viewed
from the fan end is clockwise)
• Check valve installed too close to the pump
Primes Slowly
• Mismatch of inner volute and impeller diameter
• Suction pipe diameter too large (larger than 1” or 1½”)
• Closed discharge valve (valve should be open)
• Inner volute o-ring chemically attacked, cut, brittle, etc.
Excessive Power Consumption
• Head lower than rating
• Excessive ow
• Specic gravity or viscosity too high
Vibration/Noise
• Loose magnet
• Drive magnet rubbing
• Pump cavitating from improper suction or feed
• Motor or piping not properly secured
• Foreign object in impeller
