Pumps Without Motors
Tools Required: Metric socket set, 7 mm socket (63 frame), 8 mm
socket (71 frame), 2.5 mm (56 frame), 3 mm and 4 mm Allen
wrenches, and Phillips-head screwdriver.
1. Remove the pump, drive magnet assembly and hardware
package from the carton.
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 result-
ing in injury or damage.

3. Install the motor adapter flange (item 6) on the motor face
using motor adapter flange bolts (item 12).
NOTE: Apply anti-seize compound on the threads of the
bolts. Hand tighten bolts being careful not to over tighten.
See figure 3.
2. Place motor on the fan end. See figure 1.
NOTE: The DB3, 4 & 5 pumps mount to either IEC
Figure 2
56, 63, 71 B14 frame motors depending on which
motor adapter is ordered. The motor adapter flange
(item 6) can be used for either frame depending on
which side is used. See stamped identification on
the flange. See figure 2. DB5.5 pumps mount to IEC
63 and 71 frame motors.
4. Make sure the motor shaft is clean and free of burrs. Coat
the motor shaft with anti-seize compound. If not installed
insert key supplied with motor into keyway on motor shaft.
NOTE: The outer drive is precision machined and has a bore
tolerance of +0.001/-0 inch. It may be necessary to tap the
drive on with a soft mallet.
5. Slide the outer drive magnet assembly (item 5) onto the mo-
tor shaft until the motor shaft contacts the snap ring in the
bore of the drive. Turn the drive by hand to make sure it
rotates freely. See figures 4 & 5.

WARNING: Be careful, magnets will try to attract tools.
6. Secure the drive on the motor shaft using bolt, lock washer
and flat washer (items 9, 10, 11). Coat the bolt threads with
anti-seize compound. Thread the bolt into the end of the mo-
tor shaft (while holding the outer drive to prevent it from
turning). See figure 6.
Tighten the bolt using the 2.5 mm allen wrench (56 frame),
7mm socket (63 frame) or 8 mm socket (71 frame) to the
following torque rating:
• 56 frame (M3) = 8 in-lbs (.9 N-m)
• 63 frame (M4) = 15 in-lbs (1.7 N-m)
• 71 frame (M5) = 30 in-lbs (3.4 N-m)

7. Tighten two set screws (item 5B) to a torque of 75 in.-lbs.
(8.5 N-m) using a 1/8” Allen wrench. See figure 6.
