KC11 Series - Self Priming Option
Installation and Maintenance Instructions
INTRODUCTION
FTI’s MagPrime Chamber provides a self-priming feature
to the KC1145 sealless centrifugal pump. A state-of-theart, one piece modular design allows the MagPrime pump
to lift liquids up to 15 feet (4.57 meters) in two minutes.
HOW IT WORKS
The MagPrime Chamber is initially filled with liquid. When
the pump is started, recirculating liquid creates a vacuum
in the suction line. This vacuum draws air from the suction line and releases it through the discharge outlet.
When the liquid in the suction line reaches the pump inlet, the pump is primed and normal operation begins (see
Figure 1).

SAFETY PRECAUTIONS
WARNING: Read this instruction manual com-pletely
before installing and operating this unit. Fail-ure to follow
these precautions can result in serious bodily injury.
WARNING: Magnetic field hazard. This pump contains
powerful rare earth magnets. When the pump is disassembled
(not connected to a motor) and the magnets are exposed,
these magnets produce powerful magnetic fields. Individuals
with cardiac pacemakes, implanted defibrillators, other
electronic medical devices, metallic prosthetic heart valves,
internal wound clips (from surgery), metalic prosthetic
devices or sickle cell anemia must not handle or be int he
proximity of the magnets contained
• Wear proper eye and skin protection when installing,
operating, and maintaining this equipment.
• All electrical wiring (e.g., motor) should be performed
by a qualified electrician.
• Never use this pump for flammables or combustibles.
• Verify chemical compatibility of the pump’s materials
of construction with the liquid being pumped.
o
• Maximum liquid temperature is 120
F (49oC).
INSTALLATION
The MagPrime Chamber comes complete with housing
gasket and hardware. The user must supply 1-1/2” rigid
suction piping and 1-1/4” discharge piping. The suction
inlet is located at the front of the priming chamber.
SECTION 1 - INSTALLATION OF MAGPRIME
CHAMBER FOR AN EXISTING KC11 PUMP
1. Remove any piping from the pump impeller housing.
2. Remove the (5) 1/4- 20 x 1” bolts and (4) Phillips pan
head screws from the impeller housing.
3. Gently tap the impeller housing’s discharge outlet
(using rubber mallet) to remove the impeller housing.
4. Save the impeller housing - DO NOT DISCARD. It is
necessary for pump assembly and disassembly.
5. Remove the old housing o-ring (item 7) from the pump
barrier (item 8) and discard.
6. Install the new housing o-ring (supplied with MagPrime Chamber) onto the pump barrier.
7. Verify that the white ceramic thrust washer is firmly
seated into the MagPrime Chamber.
8. Install the MagPrime Chamber by aligning the groove
in the MagPrime Chamber with the ridges on the
KC11 barrier. Press in place until firmly seated.
9. Install the (5) 1/4-20 x 1-3/4” hex bolts, washers and
nuts (supplied with the MagPrime Chamber). The
nuts will insert into the back tabs on the motor adapter
(item 13). Tighten each bolt to between 30 and 35
in.-lbs. (3.4 and 4.0 Nm) using star pattern sequence
(shown in Figure 2 of the KC11 Series Installation
and Maintenance Instructions). Do not overtighten.
NOTE: Periodic retightening of the bolts is required.
The bolts will loosen from vibration and the expansion/contraction of the plastic parts.
10. Firmly support the motor, prime chamber and piping.
Shim as necessary. Important: Failure to support
these items will result in damage to the pump.

11. Plumb the pump into your system. Use only 1-1/2”
rigid piping on the suction side. Important: Suction
piping must be raised approximately 7” (18 cm) above
the center line of the suction inlet on the MagPrime
Chamber (see Figure 2). This ensures proper priming
and pump operation.
Figure 2Figure 2
Figure 2
Figure 2Figure 2
12. Install 1-1/4” rigid piping on the discharge of the
MagPrime Chamber. Important: If the MagPrime
Chamber mounting and piping are not extremely rigid,
leakage can occur and possible pump damage.
TROUBLESHOOTING
If pump does not prime and begin to pump within three
minutes (specific gravity of 1.0 - higher specific gravities
require longer prime times), verify the following:
• No air leaks in suction plumbing.
• Priming chamber filled to proper level.
• The liquid’s specific gravity is not greater than 1.4.
• The impeller is a 4” or 4-1/2” version.
• The motor is at least 2900 rpm and rotating in the
proper direction.
For further troubleshooting, consult the factory.
MAINTENANCE
DISASSEMBLY
1. Drain MagPrime Chamber into an appropriate con-
tainer. Remove the 1/2” pipe plug from front of
MagPrime Chamber. Reinstall plug after draining.
SECTION 2 - INSTALLATION USING NEW KC11 AND
CUSTOMER SUPPLIED MOTOR
1. Install the KC11 pump (not MagPrime Chamber) in
accordance with “KC11 Series Installation and Maintenance Instructions: Assembly Section - steps 1 - 7.”
2. Follow installation steps 2 - 12 from Section 1 of this
manual.
SECTION 3 - INSTALLATION USING NEW KC11
WITH FACTORY SUPPLIED MOTOR
Follow installation steps 2 - 12 from Section 1 of this
manual.
OPERATION
Remove the fill port plug (located on the top of the
MagPrime Chamber). Use approximately 3 quarts (3 liters) of the liquid being pumped to fill the MagPrime
Chamber to capacity. Replace the fill port plug.
CAUTION: Do not allow MagPrime Chamber to overflow.
2. Remove the piping from the suction and discharge
on the MagPrime Chamber.
3. Remove the (5) 1/4-20 x 1- 3/4” bolts from the MagPrime Chamber.
4. Remove the MagPrime Chamber.
CAUTION: Some fluid may leak out when the
chamber is removed.
5. Reinstall the KC11 housing (saved from step 4 in
Section 1 of this manual). Using (4) Phillips pan
head screws, secure the housing to the barrier.
NOTE: Reinstalling the housing allows the impeller
and barrier to be easily and safely removed from the
motor adapter.
6. Remove the impeller and barrier in accordance with
“KC11 Series Installation and Maintenance Instructions: Maintenance Section - Disassembly,” step 4.
7. Follow the steps outlined in the “KC11 Series Installation and Maintenance Instructions: Maintenance
Section - Examination” to check for worn parts.
Replace parts as necessary.
Start the pump. Check all pump components and piping
for leaks.
NOTE: It is critical that the suction piping is air tight. Any
leaks, no matter how small, will prevent the pump from
priming properly.
8. Reassemble following the steps outlined in the “KC11
Series Installation and Maintenance Instructions:
Maintenance Section - Reassembly,” steps 1 - 4.
9. Install wet end following steps outlined in the “KC11
Series Installation and Maintenance Instructions:
Assembly Section,” step 6.
10. Reinstall the MagPrime Chamber following installation steps 2 - 12 from Section 1 of this manual.
