9. Slide the motor adapter over the shaft adapter and secure the motor face using hex
head bolts (Items 16 & 16A) and lock washers. See figure 3. Torque the hex head
bolts to the following values:
A. 145TC 3/8-16 bolt: 75 ft-lbs
B. 182/184TC, 213/215TC, 254/256TC 1/2-13 bolt: 75 ft-lbs
C. IEC 90 & 100/112 M8-1.25 bolt: 120 in-lbs
D. IEC 132 M12-1.75 bolt: 35 ft-lbs
Note: Hardware to attach motor (not shown) to motor adapter (Item 9) is to be
supplied by customer due to variations in B5 frame motors.
E. IEC 160 1/2-13 bolt: 75 ft-lbs
Note: Bolts are for motor adapter to motor adapter flange for this motor size
only.
10. Place a thin coat of anti-seize paste on the magnet drive hub on the unpainted fit
diameter. See figure 4.
11. Using the threaded studs in the shaft adapter as a guide, slide the magnet hub onto
the shaft adapter. The magnet hub and shaft adapter are held in close tolerance to
one another. Use two M8-1.25 hex head bolts to draw the hub onto the adapter as
necessary. See figure 5. Avoid hitting the outer edge of the magnet hub as impact can
damage the glue bond between the magnet and the hub.
12. Secure the magnet hub to the shaft adapter with the two M8 hex head bolts and lock
washers as well as the two M8 hex nuts with lock washers. Torque the bolts and nuts
to 120 in-lbs.
Pump to Motor Assembly
1. Place the front vapor protection o-ring (Item 24) into the groove on the motor adapter.
See arrow on figure 5.
2. Liberally apply a suitable lubricant to the o-ring.
3. Turn the two jackscrews clockwise until the heads touch the motor adapter.
4. Carefully slide the wet end towards the motor adapter until it touches the jack screws.
There will be some magnetic attraction. See figure 6.
5. Slowly and evenly, turn the jackscrews counterclockwise to allow the wet end to slowly
slide into the motor adapter. When the jackscrews are fully retracted, lift the wet end
slightly and slide it onto the motor adapter’s locating flange, being careful not to pinch
or cut the vapor protection o-ring.
6. Bolt the wet end to the motor adapter by re-installing the (4) 1/2” hex head cap screws
and torque evenly to 75 ft-lbs.

Foundation
1. The foundation that the pump will be sitting on should be strong enough to support the
pump as well as absorb any vibration that the pump will produce. A concrete platform
should be acceptable. Bolts embedded in the concrete can be placed by using a template
or drawing (see figure 7). The use of a pipe sleeve larger than the bolt will compensate for
base movement for final bolt location.
2. You must allow a gap no greater than 1 1/2 inches between the base and foundation for
grouting.

Base plate
1. The base plate of the ULTRAChem must be placed on the foundation using two sets of
wedges or shims. These shims should be placed on each side of the foundation bolts.
Provide enough clearance for proper grouting.
2. Remove any water or other debris from the anchor bolt holes prior to grouting.
3. Carefully lower the base plate onto the foundation bolts.
4. Level the base plate to within 1/8-inch over the length and 1/16-inch over the width. This can be done by adjusting the wedges.
5. Hand tighten the bolts.
