ASSEMBLY

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 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.

PUMPS WITH MOTORS

1. No assembly required. Simply unpack the pump and motor and examine for any signs of shipping damage. If damage is detected, save the packaging and notify the carrier immediately.

2. Ensure that lock rings are securely snapped in place and did not loosen during shipment.

3. To install the pump into the system, follow the installation instructions provided.

PUMPS WITHOUT MOTORS

Note: Finish Thompson has added extra weight (Flywheel item 35 in Figure

5) to several of our MSVKC Series Pumps to slow down motor start up & prevent possible magnet decoupling. It is necessary to know whether your pump was supplied with the ﬂywheel. Flywheels are supplied with all 56C NEMA & 80 Metric frame motor adapters. If you are unsure whether your pump was supplied with a ﬂywheel, please contact FTI’s Tech Service Department at PH: 800-888-3743 or email techservice@ﬁnishthompson.com.

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.

drawings 3 and 4 in Figure 1.

Figure 1

Drawing 1 shows drawing of pump mounted inside a tank with suction off the bottom of the tank and level ﬂuctuating from near top of pump column to close to the bottom of the pump.

Drawing 2 shows drawing of pump suction near tank bottom and level ﬂuctuating between the top and bottom of the tank.

Drawing 3 shows drawing of pump with suction extension and the level ﬂuctuating between startup level and low level.

Drawing 4 shows drawing of pump mounted outside the tank.

Drawing 5 shows drawing of pump mounted outside the tank with the motor below the liquid level.

MOUNTING

A mounting plate is recommended for in-tank installations. Use a hole saw to cut holes in desired location for piping if required.

Support and securely fasten the mounting plate on all four sides if possible or on two sides if mounted in a corner. Drill holes in the mounting plate at the desired location for bolting to the tank.

A drip cover may be installed on top of the motor if desired.

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 O-ring). Damage to the discharge can occur. The O-ring is used only when there is wear and 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 startup. See

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.

ELECTRICAL

Install motor according to NEC requirements and local electrical codes. Motor should have an overload protection circuit.

Important. To verify the correct motor rotation:

1. Install the pump into the system.

2. Fully open suction and discharge valves.

3. Allow ﬂuid to ﬂow into the pump. Do not allow the pump to run dry (PTFE & ceramic bushings can not be allowed to run dry without damage to pump components).

4. Jog the motor (allow it to run for one to two seconds) and observe rotation of the motor fan. Refer to directional arrow on the pump.

Note: A pump running backwards will pump but at a greatly reduced ﬂow and pressure.

OPERATION

1. Completely open the discharge valve. On pumps equipped with a discharge check valve, open air bleed valve on initial startup.

2. Start the pump and check liquid ﬂow. If there is no ﬂow, see the Troubleshooting section.

3. Adjust the ﬂow rate and pressure by regulating the discharge valve.

MAINTENANCE

DISASSEMBLY

1. Disconnect the power and remove the wiring.

2. Close the discharge valve and disconnect the piping.

3. Remove the mounting bolts and pull the pump from the tank. Securely anchor or clamp the motor to a workbench in a horizontal position.

4. Gently tap the locking ring (item 11 closest to pump end) toward the motor until it is loose. Mark a matching line on the barrier/column housing adapter (item 16) and the 2nd stage impeller housing (item

20) as a discharge orientation reference during re-assembly. Using a strap wrench on the barrier/column housing adapter (item 16), turn it counterclockwise and remove it from the pump column. When it is unthreaded, pull it straight off to expose the drive magnet assembly (item 14).

5. Place the pump end / barrier column housing adapter on a clean work surface with the suction pointing straight up. Remove the six screws and washers (items 25A,B, & C) from the impeller housing.

6. Using a thin bladed screwdriver, gently separate the 1st stage housing (item 24) from the diffuser (item 22). Remove the 1st stage impeller housing (item 24) being careful to pull straight off so as not to damage the ceramic front spindle support. Remove the housing O-ring (item

17). Holding down on the outside of the diffuser assembly (item 22) with one hand, gently pull the 1st stage impeller/impeller drive shaft assembly (items 19 & 23) from the pump.

7. Remove the diffuser assembly (item 22) and the diffuser O-ring (item

21) from the top of the 2nd stage impeller housing (item 20). Remove the 2nd stage impeller housing (item 20), the housing O-ring (item 17), and the 2nd stage impeller assembly (items 18 & 19) from the barrier/ column-housing adapter (item 16).

8. If further disassembly is required, place a 9/16-inch wrench on the ﬂat area of the pump shaft (item 13) on the motor side of the drive magnet assembly (item 14).

Holding the pump shaft with the wrench, remove the locking nut (item

15) by turning it clockwise (left hand thread). After the nut is removed, unthread the drive magnet assembly (item 14).

9. If the pump is longer than 12 inches, you remove each of the column extensions (item 30) by doing the following. Loosen the two set screws on the shaft bearing (item 31), gently tap the locking ring (item 11) toward the motor, and use the strap wrench to unthread the section.

10. When you are down to the motor adapter (item 9), mark a matching line on the adapter ﬂange, mounting plate (item 10), and the motor to be referenced during reassembly. Loosen the setscrews on the shaft bearing (item 31). Remove the 4 motor adapter bolts and washers (items 6, 7, & 8), the mounting plate (item 10), the motor adapter (item 9), and the metric motor adapter (item 2) if required. If motor is to be replaced, remove the coupling insert and coupling half (part of item 29).

CAUTION: Keep the drive magnet assembly and the impeller drives away from metal chips or particles

EXAMINATION/REPLACEMENT OF PARTS

1. Inspect the bushings (items 18A) in both the impeller drive (item 18) and the impeller drive shaft (item 23). See ﬁgure 2. If bushing in impeller drive (item 18) requires replacement, grip the impeller assembly (items 18 & 19) with the bushing side up, and gently tap the impeller (item

19) off the impeller drive (item 18). Insert a 1/16-inch punch into the balance hole (inner circle of four holes) on top of the impeller drive (item

18) and gently tap out the bushing. The punch may need to be moved to a second hole to complete the removal. Install the new bushing by gently pressing it in until it bottoms out (use a block of wood and a mallet if necessary). If the bushing in the impeller drive shaft is worn or cracked, the complete impeller drive shaft with bushing (item 23) needs to be replaced.

2. Inspect both thrust rings (item 19A) for wear. See ﬁgure 2. If replacement is necessary pull the old ring out, align the ﬂat on the new ring and the seating area and press into place.

Figure 2

3. Inspect both ceramic housing thrust rings and both the barrier ceramic post and the 1st stage impeller housing ceramic support post for cracks, chips, scoring, or excessive wear. Replace as required.

4. Check for loose magnets on the drive hub (item 14) or rubbed areas on the barrier/column housing adapter (item 16) or impeller assemblies. Contact your distributor or FTI Technical Service if a problem is found.

5. Inspect the bearing(s) for damage and replace if necessary. To remove the bearing, unscrew the four retaining screws (item 32) and press the bearing out (note: the top of the bearing where the set screws are faces away from the motor). Installation of the new bearing requires pressing it into the section with the set screws/collar facing away from the motor, and replacing the retaining screws.

6. Examine all the plastic parts for damage or wear. Replace as needed.

7. Examine all of the o-rings for nicks or chemical attack and replace as needed.

8. If the motor requires replacement, loosen the set screws and remove the coupling half (part of item 29) from the motor shaft.

REASSEMBLY

1. If the motor was replaced-

Slide the coupling half (half of #29) on to the motor shaft with the

splines facing away from the motor. On 56C motors, set coupling half so that motor shaft is recessed 7/32”.

For 63 and 71 frame motors, set coupling half so that motor shaft is

recessed 7/16”, and on 80 frame motors set coupling half so that it is ﬂush with the motor shaft.

2. On 56C, 63, & 80 frame motors, align one set screw with ﬂat or key slot on motor shaft and tighten both set screws with a 1/8” Allen wrench to 70 in.-lbs. (7.9 N-m). For 71 frame motors, align both set screws 90 degrees from motor ﬂat or key slot and tighten as instructed above.

3. If the shaft was replaced, slide the second coupling half onto the pump shaft (the end with the milled ﬂat) with the splined side facing away from the threaded end of the shaft. For 56C motor frames, set the coupling with the pump shaft recessed 7/32”. For 63 and 71 motor frames, set it with the pump shaft recessed 7/16”. For 80 frame, the pump shaft should be recessed ¼”. When coupling half is set correctly, align set screw with the ﬂat on the pump shaft, and tighten both set screws with 1/8”allen wrench to 70 in.-lbs. (7.9 N-m).

4. Place the motor gently on the fan cover for reassembly. For metric frame pumps, install the metric motor adapter ﬂange (item 2) onto the motor with the correct hardware (items 3, 4, & 5). One side of the adapter ﬁts 63 & 80 frame motors (side B) and the other side ﬁts the 71 frame motors (side A). The letters A & B are molded onto the adapter. For 71 frame motors the “A” must face the motor, and for 63 & 80 frame motors the “B” must face the motor. The metric motor adapter must be oriented so that the adapter seats completely onto the motor rabbet. Make sure your orientation marks are aligned (step 10 of disassembly instructions).

CAUTION: Improper orientation of the metric motor adapter can cause

premature coupling failure or cause the pump shaft to bottom out on the motor shaft before

5. Install the coupling insert (center plastic part of item 29) onto the coupling half on the motor. Now insert the pump shaft with coupling half into the coupling insert until it is completely seated.

6. Locating the pump shaft through the bearing in the motor adapter section (item 9) carefully slide the motor adapter (item 9) down the shaft until it is fully seated on the (56C) motor rabbet or (63, 71, 80 frame) on the metric motor adapter. If a mounting plate (item 10) is being used, gently slide it over the pump shaft and the motor adapter section (item 9).

7. Rotate the mounting plate and the motor adapter to the desired orientation (marked before disassembly), and align the holes through the mounting plate, motor adapter and into the motor (metric motor adapter if used). Secure the mounting plate and the adapter to the motor (item 1)/metric adapter (item 2) using the correct hardware (items 6, 7, & 8 for 56C or item 33 for metric).

8. Tap down gently with a rubber mallet on the top of the pump shaft to ensure compete coupling engagement. Tighten both bearing set screws onto the pump shaft using a 3/32” Allen wrench. Replace if needed and lubricate the two motor adapter/ column extensions o-rings (item 12) with a chemically compatible thread lubricant.

9. For 12” pumps, go to step 10. For 18” or longer pumps, slide the lock ring (item 11) past the corresponding ﬂats toward the motor. Make sure to place the smaller inside diameter side of the lock ring toward the motor. Use a chemically compatible thread lubricant to lubricate the external plastic threads on the motor adapter (item 9) and the internal

plastic threads on the column extension (item 30). Gently slide the

column extension with bearing onto the pump shaft. Install if needed and lubricatethe two column extension o-rings (item 12). Repeat step 9 for each column extension to be installed.

10. Thread the left hand threaded drive magnet assembly (item 14) onto the pump shaft until it is 4” +/- 1/64” as measured from the top of the drive magnet assembly as shown in Figure 3. A 9/16” wrench can be used on the milled ﬂats below the threads to hold the pump shaft during this step. Apply a small amunt of Loctite Thread Locker 262 to the left-hand threaded 5/8-18 hex jam nut (item 15) and thread onto the pump shaft. Tighten to 50 ft. lbs. Recheck the drive setting dimension after the nut is tightened.

Figure 3

11. Place the barrier/housing adapter on a clean surface with the white ceramic post facing up. Place the impeller drive assembly (items 18 and 19) onto the ceramic post. Install and lubricate (with a chemically compatitible lubricant) the housing o-ring (item 17).

12. Noting the reference marks made during disassembly on the impeller housing and the barrier column assembly, align the bolt hole tabs and snap the housing in place (bolt hole alignment is critical).

13. Install and lubricate the diffuser o-ring (item 21). Install the diffuser assembly (item 22) being careful not to dislodge the o-ring and to keep the bolt hole alignment straight.

14. If the impeller drive shaft (item 23) was replaced, reassemble it onto the impeller assembly (item 19) by matching the three tabs on the end of the drive shaft with the three recessed slots in the impeller assembly and pressing together.

15. Looking through the hole in the center of the diffuser assembly, note the orientatin of the square recess in the top of the ﬁrst stage impeller drive (item 18). Insert the square end of the drive shaft through the hole in the diffuser and into the square recess in the impeller driive. Press gently but ﬁrmly to seat the drive shaft.

16. Install and lubricate the housing o-ring (item 17) onto the diffuser (item

22). Lower the ﬁrst stage impeller housing (item 24) straight down onto the pump with the ceramic front spindle support sliding into the bushing (item 18A) on top of the ﬁrst stage impeller assembly. Orient the housing with the direction arrow on top (same as discharge direction), the drain boss on the bottom, andwith the mounting holes aligned. Install the mounting bolts and hardware (items 25A, B & C) making sure not to dislodge the housing o-ring (item 17) or the diffuser o-ring (item 21). Hand tighten the mounting bolts to pull the pump together using the pattern shown in Figure 4.

Figure 4

Note: It is not recommended to reuse plastic screws. Always use

thread lubricant when installing plastic screws.

17. After the housing is secure, insert a screw driver into the suction and push down on the front of the ﬁrst stage impeller assembly to completely seat the drive shaft (item 23) into the 2nd stage impeller (item 18). Push ﬁrmly on all three areas separated by the front spindle support in the suction.

CAUTION: Do not press on the gray thrust ring.

18. Slide the lock ring (item 11) over the drive magnet assembly and past the corresponding ﬂats on the column extension (motor adapter if 12” pump) making sure the smaller inside diameter side is toward the motor. Lubricate the external threads on the column extension (motor adapter on 12” models), the o-rings, and the internal threads on the barrier column section. Gripping the assembled pump end ﬁrmly, slide it down over the drive hub until the threads touch, and screw the pump end onto the column section. Use a strap wrench to tighten until there is no gap between the sections and the ﬂats are parallel. Pull the lock ring up. Match with corresponding ﬂats and snap into place.

CAUTION: Do not allow your ﬁngers to get between the drive hub and

the barrier column section during assembly.

19. Rotate the motor fan and listen/feel for drive hub rubbing (recheck drive hub setting) or the ﬁrst stage impeller (item 19) rubbing on the housing (recheck step 17).

20. Reinstall the pump into the system according to the installation instructions.

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 or the

mounting plate. The ﬁrst line is the model number, and the second line is the serial number.

7. The pump will contain various numbers of shaft bearings (item 28) based on the length of the pump as follows:

18” pump = (1) shaft bearings

24” pump = (2) shaft bearings 30” pump = (3) shaft bearings 36” pump = (4) shaft bearings 42” pump = (5) shaft bearings 48” pump = (6) shaft bearings 54” pump = (7) shaft bearings 60” pump = (8) shaft bearings

8. Due to the hermetically sealed design, the pump will displace liquid as follows:

18” pump = approximately 1-1/4 gallons (4.73 liters)

Add approximately 1 quart (.95 liter) per column section.

E.G. 24” pump = 1-1/2 gallons (5.68 liters)

9. 18” pumps do not have column extensions.

10. Largest diameter impeller is always closest to motor.
