Safety Precautions
WARNING: READ THIS MANUAL COMPLETELY BEFORE INSTALLING AND OPERATING THIS UNIT. FAILURE TO FOLLOW THESE PRECAUTIONS CAN RESULT IN SERIOUS INJURY OR DEATH.
WARNING: Magnetic field hazard. This pump contains powerful magnets. Exposed magnets (pump not connected
to motor) produce powerful magnetic fields. Individuals with cardiac pacemakers, implanted defibrillators, other electronic 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 specific recommendations before working with this pump.
WARNING: Magnetic force hazard. This pump should only be disassembled and assembled using the recommended procedures. The magnetic attraction is powerful enough to rapidly pull the motor end and the wet end together. Do not
place fingers 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 floppy 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.
If using the SP Series to pump non-flammable or non-combustible liquids in a hazardous area, you must 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.
3
WARNING: Chemical Hazard. This pump is used for transferring many types of potentially dangerous chemicals.
Always wear protective clothing, 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 flow or with the discharge valve closed. This could lead to pump
failure.
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 1 US gallon (3.8 liters) of priming fluid 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 run 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 the frequency for which the pump was designed
(for example, if the pump is a 50 Hz model, do not exceed 50 Hz).
SP11/15 Capabilities
Maximum Working Pressure: 90 psi (6.2 bar)
Maximum Temperature: Polypropylene: 180º F (82º C); PVDF: 220º F (104º C)
NOTE: Maximum temperature is application dependent. Consult a chemical resistance guide or the chemical
manufacturer for chemical compatibility and temperature limits.
Maximum Lift: 25 feet (7.6 meters)
NOTE: Lift determined on fresh, cold water with 1 1/2” Schedule 40 pipe. Specific gravity affects lift capability.
Divide 25 feet (7.6 meters) by the specific gravity to determine equivalent maximum lift.
Solids: Maximum particle size is 100 microns for slurries and 1/64” (.4 mm) for occasional solids. Maximum hardness
is 80 HS. Maximum concentration is 10% by weight. If solids are being pumped, it is recommended that the pump have
either ceramic or for best results, silicon carbide components. Pumping solids may lead to increased wear.
NOTE: While the pump is capable of being used in sump applications, it is NOT a trash pump. Care must be taken
to ensure that debris and foreign objects do not enter the pump or damage may result. A 1-1/2” strainer basket with
1/8” (32mm) perforations is suggested. Regular strainer basket maintenance is required to prevent plugging and
decrease in NPSHa so as not to starve and damage the pump.

Pumps with Motors
Proceed
to “Installation” Section
Pumps Without Motors
NOTE: 184TC and 100/112 frame motors must have motor feet.
1. Remove the pump, drive magnet assembly and hardware package from the carton.
CAUTION: Keep away from metallic particles, tools and electronics.
Drive magnets MUST be free of metal chips.
WARNING: Keep the drive magnet away from the open end of the motor adapter and barrier.
Strong magnetic attraction could allow the drive hub to enter the motor adapter resulting in injury
or damage.
2. Place motor on the fan end. For 56C/145TC and
B5 frame motors go to step 4. See figure 1.
Figure 1
3. For 184 NEMA and IEC motors only - Install the motor
adapter flange (item 14) on the motor face using bolts,
lock washers and flat washers (items 25, 26, 27). See figure 2.
NOTE: Apply anti-seize compound on threads of the bolts.
Torque bolts to the following:
• 80 frame (M6) • 90/100/112 frame (M8) =
130 in-lb (14.7 N-m)
• 184 NEMA (1/2”) 480 in-lb (54.3 N-m)
=
=
90 in-lb (10.2 N-m)
Figure 2
4. Coat the motor shaft with anti-seize compound. Insert key
supplied with motor into keyway on motor shaft. See figure 3.
NOTE: Make sure the motor shaft is clean and free of burrs.
The outer drive is precision machined and has a bore tolerance of +.0005/-0 inch.
Figure 3
5. Slide the outer drive magnet assembly (item 13) onto the motor
shaft until the motor shaft contacts the snap ring in the bore
of the drive. Figures 4 and 5.
6. Secure the drive on the motor shaft.
Figure 4

Figure 5
WARNING: Be careful, magnets will try to attract tools.
Metric Motors: Secure the drive to the motor shaft using bolt, lock washer and flat washer (items 19, 20, 21). Thread the bolt into the end of the motor shaft (while holding the outer drive to prevent it from turning). See figure 6.
Tighten the bolt to the following:
* 80 frame (M6)
=
90 in-lb (10.2 N-m)
* 90 frame (M8) =
130 in-lb (14.7 N-m)
* 100/112 frame (M10) =
240 in-lb (27.1 N-m)
NEMA Motors: Install set screws (item 13A) into threaded holes on
the side of the outer drive magnet assembly. Using a 3/16” Allen wrench,
tighten to 228 in-lbs (25.8 N-m). See figure 7.
Figure 6 - IEC
7. Install the pump end on the motor/drive magnet assembly. With the motor
facing upright, align the pump feet so that the motor feet and pump feet
are on the same side.
Tip the pump end at an angle (discharge is approximately 45º) so that it is
just touching the edge of the outer drive magnet assembly. See figure 8.
Carefully lower the pump onto the drive magnet assembly by tipping discharge
forward to 90º and dropping straight down. The last 3-4 inches (8-10 cm) before
the pump reaches the motor will have STRONG magnetic attraction between the
pump and outer drive magnet assembly.
8. Secure the pump to the motor with (4) 3/8” bolts, lock washers
and flat washers (items 22, 23. 24). See figures 9 and 10.

Section II - Installation
SP Piping Diagram
Mounting Pump foot should be securely
fastened to a solid foundation. If
the pump was received with plastic
shipping shims, it is possible to
use these as additional support
for the motor feet (though not
required).
NOTE: B5 pumps with
100/112 frame do not include a
pump foot.
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
calculated 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 specific gravity must not exceed 25 feet (7.6 meters).
NOTE: Maximum suction lift is reduced by 1.13 feet (.34 meters) for every 1,000 feet (304 meters) 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 fittings 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 performance. The suction piping should be level or slope slightly upward to the pump.
• The suction pipe should be 1 1/2” (38 mm). Larger suction piping will affect priming ability. Smaller piping affects
NPSH available and pump performance.
• Provide for adequate suction submergence. Excessive submergence will reduce pump performance.
• The end of the pipe should be at least 3” (7.6 cm) above the bottom of the suction tank.
• If a strainer is used, it 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 regulat-
ing flow. 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.
8
• NOTE: If a check valve is used in the discharge line, it must be placed at a distance at least equal to the maximum
suction lift from the pump. If this cannot be done, an air vent must be provided in the discharge line.
• If flexible hose is preferred over pipe, use a reinforced hose rated for the proper temperature, pressure and is chemically resistant against the fluid being pumped.
• The suction valve must be completely open to avoid restricting the suction flow.
• When installing pumps with flanges, we recommend use of low seating stress gaskets such as Gore-Tex or Gylon
(expanded PTFE).
• It is advisable to install a flush system in the piping to allow the pump to be flushed before the pump is removed
from service.
NOTE: The pump is provided with a 1/2” BSP drain in the impeller housing.
• A “tee” can be installed in the discharge piping as an alternative location for filling the housing with fluid before
pump operation.
• “Filling” is defined as filling the housing with 1 US gallon (3.8 liters) of liquid
• “Priming” is defined as evacuating all the air from the suction piping/pump and replacing it with fluid.
Motor/Electrical
Install the motor according to NEC requirements and local electrical codes. The motor should have an overload protection 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 fill plug (item 3A, 3 next to discharge) and fill the housing with 1 US gallon (3.8 liters) of the service
liquid or water. Replace fill plug and tighten until the o-ring is seated.
NOTE: Use a funnel with flexible spout to fill the housing on pumps equipped with flanges.
3. Fully open the suction and discharge valves.
4. Jog the motor (allow it to run for 1-2 seconds) and observe the rotation of the motor fan. Refer to the directional
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
1. Be sure the housing (item 1) has been filled with 1 US gallon (3.8 liters) of service liquid and the fill plug (item
3A, 3) has been installed and tightened until the o-ring is seated.
2. Open the inlet (suction) and discharge valves completely.
3. Turn the pump on. Wait for discharge pressure and flow to stabilize (could take several minutes depending upon
suction lift). Adjust the flow rate and pressure by regulating the discharge valve. Do not attempt to adjust the flow
with the suction valve.
9
Section IV - Shutdown
• Turn off the motor.
NOTE: When the pump is stopped without a check valve in the piping, liquid will flow 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 refill with liquid.
Flush Systems
CAUTION: Some fluids react with water; use compatible flushing fluid.
1. Turn off the pump.
2. Completely close the suction and discharge valves.
3. Connect flushing fluid supply to flush inlet valve.
4. Connect flushing fluid drain to flush drain valve.
5. Open flushing inlet and outlet valves. Flush system until the pump is clean.
NOTE: The drain can be used as the flushing drain valve using appropriate customer supplied fittings. Using the drain helps to promote superior flushing and draining results.
Maintenance
Recommended maintenance schedule
The recommended maintenance schedule depends upon the nature of the fluid being pumped and the specific application. If the pump is used on a clean fluid, 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 fluids with solids, high temperatures or other conditions 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 specific maintenance schedule can be determined. For best results, the pump should be removed from service annually for examination.
Section V - Disassembly
Tools Required: Metric socket or wrench set, 9/16” socket or wrench, 8 mm Allen wrench, and 3/16” Allen wrench
(NEMA motors only), and pliers (for fill/drain plugs).
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, 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: Magnetic force hazard. This pump should only be disassembled and assembled using the recommended procedures. The magnetic attraction is powerful enough to rapidly pull the motor end and the wet end together. Do not place fingers 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.
1. Stop the pump, lock out the motor starter, close all the valves that are connected to the pump, and drain/decontaminate the pump.

5. For 56C, 145TC and 80 frame B14, re-install the plastic
foot (item 15) to the motor adapter (item 12D). Use the
longer M6 bolts, lock washers and flat washers (items 28A,
29 and 30) for the front bolt holes towards the clamp ring.
See figure 40. Use the shorter M6 bolts, lock washers and
flat washers (items 28, 29 and 30) for the rear bolt holes
towards the motor face. NOTE: Nuts (item 31) are glued
Figure 41
Figure 40
into the rear of the motor adapter to help with the installation of the rear bolts. Make sure the nuts are still in place.
See figure 41. Tighten bolts to 5 ft-lbs. (6.8 N-m). For 184 frame, IEC 90, 100/112 frame B14 and 80/90 frame
B5, leave the foot off until the motor adapter is installed on the motor. This will allow easier access to the bottom
bolt hole in the motor adapter.
6. Position the motor adapter assembly on a flat surface. If the foot is installed, allow the feet to hang over the edge.
see figure 42. Install the o-ring (item 12A) into the groove on the clamp ring. Lubricate the o-ring with a compatible lubricant. See figure 43.

Figure 43
7. Install the barrier (item 11) into the clamp ring (item 12B). Line up the prong that has no prong opposite it with
the 2 o’clock housing bolt hole in the clamp ring. See figure 43A. NOTE: Leave the barrier loose in the clamp
until installing the housing (item 1) to make sure the bolt holes line up.
8. Install o-ring (item 10) in groove in barrier. Make sure it is tucked in all the way around. See figure 44.
9. Install impeller shaft (item 9) into barrier by aligning the flats on the shaft with the ones in the barrier. Make sure
it is completely seated. See figure 44
10. Carefully install the impeller/inner drive assembly (items 7A, 7, 8, 8A) 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. See figures 45 and 46.

Figure 45
Figure 46
11. Install the inner volute (item 6) by lining up the prongs of the barrier with the channels in the inner volute. Press
down evenly until the prongs snap onto the surface of the inner volute. See figures 47 and 48.
16
Figure 47
Figure 48
12. Install the separator plate (item 4) 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 figure 49.
13. Lubricate the inner volute o-ring (item 5) with a chemically compatible lubricant and install in the groove on the
round suction nozzle in the center of the inner volute. See figure 50.
Figure 49
Figure 50
14. Lubricate the inside of the gooseneck. See figure 51. Install the housing (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). See
Figure 51. Using uniform pressure, press the housing and barrier into place until it is flush with the motor adapter.
See figure 52.
Figure 52
Figure 51
Note: The fit is tight due to inner volute o-ring. Make sure o-ring is lubricated.
Install the housing bolts, lock washers and flat washers (items 16, 17, 18). Tighten all bolts evenly using a star pattern. Tighten to 20 foot-lbs (27 N-m).
15. Reinstall the pump on the motor/drive magnet following instructions found in “Assembly, Pumps without Motors,” steps 7-10.

SP11 / SP15 PART NUMBER EXPLANATION
NOTE: Pump end includes wetted components, drive magnet and motor adapter. The wet end incudes wetted components only.
Part Number Explanation
The base model number contains standard components. Where standard components are not suitable, add the alternative component code
after the base model number to substitute components. Example: SP11-E-U-14 is constructed of the listed base model components except it
has an EPDM o-rnig, union connections, and a 145TC motor adapter.
The model number is on the serial number label located on the motor adapter. The model number contains a base model that features certain
standard components.
Compare the model number on the pump to the adjacent chart to determine if the pump contains any alternate components. Model numbers
containing “P” have primary components molded from polypropylene. Model numbers containing “V” have primary components molded from
PVDF.
Base model numbers are: SP11P, SP11V.

Section VII - Troubleshooting
General Notes:
• Cold water can contain dissolved air. Under high lift applications, the air can come out of solution blocking suction passages. This can lead to lack of priming, slow priming or low flow rates.
Do not pump liquids containing ferrous metal fines.
• If magnets de-couple, stop pump immediately. Operating the pump with the magnets de-coupled will eventually weaken the magnets.
• Do not use mismatched drive magnet assemblies (different number of magnets on inner and outer drive magnet assemblies).
• Contact our Technical Service Department at 1-800-888-3743 or by e-mail at techservice@finishthompson.com if you have any questions regarding product operation or repair.
No or Insufficient Discharge
• Air leaks in suction piping
• Housing not filled with priming fluid
• Suction pipe smaller than 1 1/2”
• Suction pipe contains high spots causing trapped air pockets
• Suction pipe excessively long (flow drops as suction pipe gets longer)
• System head higher than anticipated
• Closed valve
• Viscosity or specific gravity too high
• Motor too large for magnet coupling rating (magnets uncoupled)
• Suction lift too high or insufficient NPSH
• Clogged suction line, suction strainer (if used) or impeller vanes
Insufficient Pressure
• Air or gas entrained liquid
• Impeller diameter too small
• System head lower than anticipated
• Motors speed insufficient (too low) or motor rotation incorrect (correct rotation when viewed from the fan end is clockwise)
Won’t Prime
• Did not fill housing with fluid 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 SP11/15 Capabilities section)
• Suction pipe diameter too large
• Specific gravity or local atmospheric pressure (altitude/elevation) not accounted for in lift calculations
• Mismatch 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
24
Primes Slowly
• Mismatch of inner volute and impeller diameter
• Suction pipe diameter too large (larger than 1 1/2”)
• Closed discharge valve (valve should be open)
• Inner volute o-ring chemically attacked, cut, brittle, etc.
Excessive Power Consumption
• Head lower than rating
• Excessive flow
• Specific 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
