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. ALWAYS use the jackscrews
(item 14) to assemble/disassemble the pump. 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.
CAUTION: Keep the drive hub 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.
3. For 160 B5 IEC frames only:
A. Place the vapor protection ring into the groove on the motor adapter flange (Item 10)
Use petroleum jelly or similar substance to help keep the o-ring in place.
B. Place the motor adapter flange into position on the motor face using customer
supplied hardware.
Note: Hardware to attach the motor (not shown) to the adapter flange (Item 10) is to be
supplied by customer due to variations in B5 frame motors.
C. Continue to step 5.
4. For NEMA 143-145TC, 182-184TC, 213-215TC, & 254-256TC motor frames:
A. Slide shaft adapter onto motor shaft until end of shaft is firmly against retaining
ring. See figure 1. The shaft adapter is held to a tight tolerance with motor shaft.
It may be necessary to tap the shaft adapter into position using a dead blow hammer.
B. Using a 3/16” T-handled Allen wrench, tighten both setscrews to 228 in-lbs.
5. For 90, 132, & 160 IEC motor frames:
A. Slide the shaft adapter onto motor shaft until end of shaft is firmly against retaining
ring. The shaft adapter is held to a tight tolerance with the motor shaft. It may be
necessary to tap the shaft adapter into position using a dead blow hammer.
B. Install the appropriate hex bolt, drive washer, and lock washer (Items 18, 19, & 20)
into the end of the motor shaft and then tighten to the following torque settings:
i. 90 frame B14: 120 in-lbs
ii. 132 frame B5: 35 ft-lbs
iii. 160 frame B5: 90 ft-lbs
6. For 100/112 IEC frame B14 motor frames:
A. Slide the shaft adapter onto motor shaft until end of shaft is firmly against retaining
ring. The shaft adapter is held to a tight tolerance with motor shaft. It may be
necessary to tap the shaft adapter into position using a dead blow hammer.
B. Install bolt and drive washer (Items 18 & 20), tapered side out, and torque to 250
in-lbs.
7. Using a 3/4” socket, unbolt the wet end (Items 1 through 7) from the motor adapter (Item
9) by removing the (4) 1/2” hex head cap screws (Item 15). Extend the (2) jackscrews
(Item 14) using a 3/4” socket, turn the jackscrews clockwise until they are fully extended.
See figure 2.
8. Check to ensure vapor protection o-ring is present and undamaged in the groove on the
motor adapter. Use petroleum jelly or similar substance to help keep the o-ring in place.
Pumps without Motors:
1. Carefully place the motor on a suitable, level work surface (a nonmagnetic surface is preferred). Make sure the work surface is
free of metal chips or particles.
2. Coat the motor shaft with anti-seize paste.
