2
Mount pump in desired configuration. Securely fasten mounting
plate if used. Motor feet may also be used for mounting.
PIPING
1. Support piping near the pump to eliminate any strain on the pump
casings. Do not use suction or discharge piping to support the pump.
2. Do not overtighten the piping on the discharge on initial installation (i.e.,
down to the collar on NPT housings or the o-ring on BSP housings).
Damage to the discharge can occur. The o-ring on the BSP housing is
only used when the plastic threads are loose.
3. Do not place the pump suction directly on the bottom of the tank. Keep
the pump suction at least one pipe diameter off the bottom.
4. A suction extension tube of up to nine feet in length can be added.
5. To minimize head loss from friction:
a. Increase pipe size by 1 diameter.
b. Use minimal number of pipe bends.
6. If a check valve is installed in the discharge piping, an air bleed must
be installed in the discharge line to prevent air lock. This allows air
trapped in the pump internals to be removed on initial start-up. See
drawings 3 and 4 in Figure 1.
7. Maintain a flooded suction. Use a foot valve if necessary.
8. Ensure that the piping does not leak and suction is not prone to clogging. Use a strainer if necessary on the suction.
9. If flexible hose is preferred, use reinforced hose rated for the proper
temperature and pressure. This helps avoid collapse or kinks.
10. Install valves a minimum of 10 pipe diameters from the pump.
CAUTION: To stop the pump if prime is lost, use one of the
following: (1) pressure switch on the discharge or (2) motor
minder to monitor motor current.
1. Completely open discharge valve. On pumps equipped with a discharge
WET END INSPECTION / REPLACEMENT
1 Disconnect the power. Unwire the motor (mark the wires for correct
rotation upon reassembly). Close the suction and discharge valves,
and remove the pump from the installation. Remove any discharge
piping that will hinder the removal of the housing.
2. Place the pump on a clean work bench and secure the motor or
mounting plate. Gently tap the locking ring (item 11) towards the motor
until it is loose (the locking ring connects the column housing adapter
(item 15) to the next section). Using a strap wrench, unthread the
column housing section turning it counterclockwise. Grasping the
discharge and pump head, pull it straight off of the pump and place it
on the bench with the suction pointing straight up.
3. Make an alignment mark on the side of the impeller housing (item 21)
and the column housing adapter (item 15) to aid in alignment during
the reassembly process. Remove the six impeller housing mounting
screws (items 22). Remove the impeller housing (item 21) and o-ring
(item 16). Grasp the impeller and remove it from the column housing
adapter (item 15).
CAUTION: Keep the drive magnet assembly (item 14) and
impeller drive (item 18) away from metal chips or particles.
Note: Keep the impeller housing o-ring (item 16) with the
impeller housing to avoid mix up during reassembly.
Figure 2
INSTALLATION
The VKC Series is a versatile pump designed to be operated in a variety of mounting configurations. The pump can be mounted either
inside or outside of a tank or sump. See Figure 1.
Note: Drawings for illustration only. Pumps need to be properly
supported when installed.
ELECTRICAL
1. Install the motor according to NEC requirements and local
electrical codes. Motor should have an overload protection
circuit.
2. Wire the motor for clockwise rotation when facing the fan
end of the motor.
3. To verify the correct motor rotation:
a. Install the pump into the system
b. Fully open the suction and discharge valves
c. Allow fluid to run into the pump. Do not allow the pump
to run dry (PTFE and ceramic bushings can’t be run dry
without causing damage to internal parts).
d. Jog the motor (allow it to run for only one to two seconds)
and observe the rotation of the motor fan. Refer to the
directional arrow by the electrical box if needed.
Note: A pump running backwards will pump but at a greatly
reduced flow and pressure.
OPERATION
EXAMINATION
1. Check the impeller drive bushing (item 17), thrust ring (item 20), ceramic thrust ring and shaft for cracks, chips, scoring or excess wear.
See figure 2. Replace as required.
2. Check for loose magnets on the drive assembly or rubbed areas on
the impeller or column housing adapter assemblies. Contact your
distributor or FTI Technical Service if a problem is found.
BUSHING REPLACEMENT
1. To remove the bushing, insert 1/16” pin punch into balance hole (inner
circle of 4 holes) of impeller assembly (items 17,18,19,20). Gently
tap the bushing out of the back of the impeller assembly. The punch
may need to be moved to a different hole if the bushing is difficult to
remove.
2. To replace the bushing, clean the impeller bore. Insert the new bushing
into the back of the impeller assembly by aligning the bushing with
the impeller bore. Press gently until the bushing bottoms out (use a
block of wood and mallet if necessary).
MOTOR REPLACEMENT
Remove the four bolts and washers (items 6, 7, and 8) securing the
motor adapter (item 9) to the motor. Carefully pull the pump away
from the motor face. Loosen the two setscrews on the coupling
half (located on the motor shaft). Remove the coupling half. Install
motor shaft coupling half onto a new motor following the assembly
instructions on page one for 56C or metric frame pumps. Make
sure the coupling insert meshes. Install pump onto the new motor.

DRIVE MAGNET ASSEMBLY, SHAFT BEARING
OR COLUMN SECTION REPLACEMENT
1. The drive magnet assembly (item 14) is locked in place with a left
hand threaded 5/8-18 jam nut (item 32). Loctite Thread Locker #262
is used to secure the jam nut and may require some heat to loosen
the bond for removal. Secure the pump shaft using the flats located
on the motor side of the drive magnet assembly, and remove the jam
nut. Unthread the drive magnet assembly (left hand thread) from the
shaft.
2. Loosen the two setscrews on the shaft bearing (item 28). Gently tap
the next locking ring (item 11) toward the motor until it is loose. Using
a strap wrench, unthread and remove the column extension (item 30).
Repeat step two for each section removed.
3. When you are down to the motor adapter section (item 9), remove the
four bolts holding the adapter (and mounting plate if you have one) to
the motor. Mark the flange on the motor adapter / mounting plate and
the motor face for correct orientation when reassembling. Remove
the mounting plate, and pull the motor adapter from the motor face.
4. 12” models will have two bearings in the motor adapter section. If
further disassembly is necessary, loosen the two setscrews on the
pump side bearing, and gently press the shaft and the second bearing toward the motor end until it loosens. If the bearing or the shaft
need replacement, loosen the setscrews and remove the pump shaft
coupling half. Loosen the setscrews on the bearing and slide it off the
shaft. On models 18” or longer, just loosen the setscrews on the pump
shaft coupling half and remove it.
5. Spin all of the bearings and visually inspect for binding or corrosion.
To replace, remove the four screws and washers (items 29 and 33).
Gently tap the bearings toward the pump end of each section until they
are loose.
6. Inspect the drive magnet assembly, each column section, all of the bearings, shaft, and o-rings for wear or damage. Replace as needed.
REASSEMBLY
1. If the shaft, or the first bearing on a 12” model was replaced, you will
need to slide the new bearing onto the shaft with the setscrew side
facing away from the motor. Adjust the bearing to the correct setting
in Figure 3, and tighten both setscrews.

bearing into the machined recess making sure to use the outer bearing
race as the point of contact.
For models 18” or longer, insert the threaded end of the pump shaft
up through the bearing already in place in the pump end of the motor
adapter. Leave the bearing setscrews loose.
4. For metric frame pumps, install the metric motor adapter flange (item
2) per instructions in step 4 of “Pumps Without Motors (Metric Frame)
from page 1.
5. Install the coupling insert onto the pump shaft coupling half. Place
motor on its fan cover on a flat clean area. Make sure the coupling
splines mesh with the insert. Install the motor adapter and pump shaft
onto the motor face. Verify the motor adapter seats completely onto
the motor rabbet (or metric motor adapter flange on metric pumps).
Install the mounting plate (if one is used) and align the marks on the
motor, the motor adapter flange and the mounting plate for correct
orientation. Install the four bolts and tighten to the motor face.
6. For 12” models, go to step 8. For models 18” or longer, rotate the
pump shaft and press down to insure complete coupling engagement.
While holding the shaft snugly down, tighten the bearing setscrews.
7. If column o-rings (item 12) were removed or need replacement,
lubricate the o-rings with a compatible lubricant and install them in
the o-ring grooves. If the bearing (item 28) was removed, press the
new bearing (only making contact with the outer bearing race) into
the recess with the extended race (setscrews) facing away from the
motor. Install the four retaining screws and washers (items 29 and 33).
8. Lubricate the motor adapter o-rings (item 12) with a compatible lubricant. Place the locking ring (item 11) (with the smaller inside diameter
side toward the motor) over the end of the column section and slide
it toward the motor. Install the column extension (item 30) by aligning
the threaded end of the shaft through the bearing and sliding it down
to the top of the motor adapter. Secure the motor and mounting plate
to the table. Using a strap wrench, thread the column extension onto
the motor adapter. Tighten the section until there is no gap between the
sections and the flats are parallel. Tighten the two bearing setscrews
into the pump shaft. Pull the locking ring (item 11) toward the pump
end until it snaps into place locking the two sections together.
9. Repeat step eight until all column extensions are installed. If the pump
is a 24” model or longer, you may need a second strap wrench to hold
the previous section in place while tightening the new one.
Note: It may be possible to slightly overtighten these sections. Simply
back off slowly until the flats are aligned and the lock ring snaps into
place.
10. Install the left hand threaded drive magnet assembly (item 14) onto
the drive shaft (item 13) until it is set at 4.00 +/- .015 as measured
from the top of the motor adapter/column extension to the top of the
drive magnet assembly. See Figure 4. Apply a small amount of Loctite
Thread Locker #262 to the inside threads on the 5/8-18 left hand jam
nut (item 32) and the outside threads on the drive shaft. Thread the
jam nut on until it makes contact with the drive. Hold the drive magnet
assembly still and tighten it to 50 ft. pounds. Recheck the drive magnet
setting after the jam nut is tight to ensure it did not move.
2. Install the key into the keyway cut in the motor end of the pump shaft
(item 13). Align the coupling half keyway slot and install the coupling
half with the splines pointing toward the motor end. For 56C frame, set
the coupling with the shaft end recessed .218”. Tighten the setscrews.
For 63 and 71 frames, set the coupling with the shaft end recessed
.437” and tighten the setscrews. For 80 frame, set the coupling with
the shaft recessed .250 and tighten the setscrews.
3. For 12” models - from the motor side, insert the threaded end of the
shaft up through the center of the motor adapter (item 9) . Press the
Figure 4

11. Reassemble the wet end by placing the impeller (items 18 and 19) onto
the ceramic shaft in the column housing adapter (item 15). Install the
housing o-ring (item 16), and lubricate with a compatible lubricant.
Align the marks made on the housing (item 21) and the column housing adapter (item 15) during disassembly. Install the impeller housing
(item 21) onto the column housing adapter taking care not to dislodge
the o-ring. Align the bolt holes and install the six mounting screws
(item 22). Use a PTFE thread lubricant on the PVDF screws. Following
the pattern in Figure 5, carefully tighten using a screwdriver. Do not
over- tighten the screws (recommended maximum torque is 25 in-lbs.)
Reach into the suction and spin the impeller with your finger to verify
it is not rubbing or binding.
Figure 5
12. Slide the locking ring over the end of the column extension with the
smaller inside diameter side toward the motor. Lubricate the column
rings (item 12) with a compatible lubricant and install the “wet end”
by threading it on until the flats line up. Pull the locking ring toward
the pump end and snap it in place locking the two sections together.
Rotate the motor fan by hand to verify nothing is rubbing or binding. Reinstall
13.
the pump into the system according to the installation instructions.
7. The pump will contain various numbers of shaft bearings (item 28)
based on the length of the pump as follows:
12” pump = (2) shaft bearing
18” pump = (2) shaft bearings
24” pump = (3) shaft bearings
30” pump = (4) shaft bearings
36” pump = (5) shaft bearings
42” pump = (6) shaft bearings
48” pump = (7) shaft bearings
54” pump = (8) shaft bearings
60” pump = (9) shaft bearings
8. Due to the hermetically sealed design, the pump will displace liquid
as follows:
12” pump = approximately 1 gallon (3.78 liters)
Add approximately 1 quart (.95 liter) per column section.
E.G. 24” pump = 1-1/2 gallons (4.73 liters)
9. 12” pumps do not have column extensions.
GENERAL NOTES
1. Do not pump liquids containing metal fines.
2. If magnets decouple, stop the pump immediately. The rare earth
magnets used in this pump are more resistant to demagnetization,
but operating the pump with the magnets decoupled will eventually
weaken the magnets.
3. Plastic pumps will expand and contract with temperature so periodically
check and hand tighten screws.
4. Use a chemically compatible thread lubricant on threads of column
sections.
5. The setting of the drive magnet dimension is critical. Failure to properly set the dimension may result in decoupling or damage to pump
components.
6. An information sticker is attached to the motor adapter section. The
first line is the model number, the second is the serial number. See
Figure 6.
