Outer Magnet Installation Diagrams
The procedure for installing the outer magnet on the motor shaft is dependent on which motor frame is used
with the pump. The four standard cases are described below:
I. NEMA 56C & IEC 90 Frames:
The end of the motor shaft must
be flush with the inner surface of
the outer magnet's hub.
NOTE: The IEC motor must have a B5 Flange to be
compatible with the pump mounting bracket.
II. NEMA 143TC & 145TC Frames:
The motor shaft must protrude past
the inner surface of the outer magnet's
hub by 1/16 in. (1.6 mm).
III. IEC 71, 80, 100 & 112 Frames:
The outer magnet's hub is positioned
by a snap ring installed in the hub. The
end of the motor shaft must contact the
snap ring.
NOTE: The IEC motor must have a B5 Flange, as shown,
to be compatible with the pump mounting bracket
EC 100 & 112 frames utilize an adapter plate (provided,
but not shown) similar to the picture below.
IV. NEMA 182TC & 184TC Frames:

the motor to the pedestal. The outer magnet's
hub is positioned by a snap ring installed in the
hub. The end of the motor shaft must contact
the snap ring.
NOTE: Complete pumps ordered for use with NEMA
182/184TC motor frames will be supplied with
the adapter plate (P/N SP0046) and adapter
mounting bolts (P/N 641105).
