DB11/15 ASSEMBLY, INSTALLATION & OPERATION
Unpacking and Inspection
Unpack the pump and examine for any signs of shipping damage.
If damage is detected, save the packaging and notify the carrier
immediately.
Section I - Assembly
Pumps with Motors
Proceed to “Installation” Section.
Pumps Without Motors
NOTE: 184TC and 100/112 frame motors must have feet.
Tools Required - Metric socket or wrench set, 9/16” socket
or wrench and 3/16” Allen Wrench (NEMA motors only).
1. Remove the pump, drive magnet assembly and hardware
package from the carton. Do not remove the shipping
plug until after the pump has been installed on the motor.
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.
3. For 184 NEMA and IEC motors only -
install the motor adapter flange (item
10) on the motor face using bolts, lock
washers and flat washers (items 21,
22, 23). See figure 2.
Torque bolts to the following:
80 frame (M6) = 90 in-lb (10.2
N-m)
90/100/112 frame (M8) = 130 in-lb (14.7 N-m)
184 NEMA (1/2”) = 300 in-lb (33.9 N-m)
4. Coat the motor shaft with
anti-seize compound. Insert
key supplied with motor into
keyway on motor shaft. See
figure 3.
5. Slide the outer drive magnet assembly (item 9) 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 6 - IEC Drive
NEMA Motors: Install set screws (item 9A) 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 7 - NEMA Drive

Figure 2
Figure 3
Metric Motors: Secure the drive to the motor shaft using
bolt, lock washer and flat washer (items 18, 19, 20).
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)
Figure 4 Figure 5
WARNING: Be careful, magnets will try to attract tools.
2. Place motor on the fan end. For
56C/145TC and B5 frame motors go to
step 4. See figure 1.
Note: Apply anti-seize compound on threads of the bolts .
7. For NEMA 56C and 145TC frame motors:
Install o-ring (item 8E) in the groove on the back of the motor
adapter (item 8D). Use petroleum jelly to hold the o-ring in
place during installation. Note: 184TC and metric adapters
do not use this o-ring
