6.14 Wet / Drive End Assembly
Assembling the close-coupled motor
requires significant care. The magnetic coupling
between the impeller and outer drive magnets is very
strong. It is recommended to have a second person
with non-metallic spacers to place between the adapter
[1340] and containment ring [3830] to assist in
assembly.
6.14.1 Piped Up Assembly
a) Line up the drive end with the wet end, ensuring
proper motor and adapter height relative to the
wet end.
b) Carefully slide the motor forward until it engages
with the containment ring [3830] without a gap.
c) Insert and tighten the (4) socket head cap screws
to hold the adapter to the wet end. Torque the
socket head cap screws to 27 Nm (20 lbf
•ft).
d) Insert and tighten any support foot [3134] and
motor foot screws to secure the assembly to the
base.
6.14.2 In-Shop Assembly
a) Holding the wet end by the suction and/or
discharge flange, carefully insert the wet end into
the drive end in a straight line as shown in Figure
6-30.
b) Insert and tighten the (4) socket head cap screws
to hold the adapter to the wet end. Torque the
socket head cap screws to 27 Nm (20 lbf
•ft).
