Slide the inner magnet (11) onto the
drive shaft (20) until it contacts the
retaining ring in the inner groove.
NOTE: Install inner magnet with orientation as
described on Page 26.

Install the second retaining ring (28)
into the outer groove, as shown.
NOTE: Use a rubber mallet, as shown, to tap the
retaining ring into the outer groove. This will lock
the inner magnet assembly on the drive shaft.

Turn the inner magnet (11) by hand to

Verify that the containment can O-ring is installed (see
containment can (12) to the pump housing using six sets of bolts (18) and lockwashers (32).
This completes the Pump Cartridge assembly.
NOTE: Apply anti-seize compound to the bolts. Refer to Appendix 1 for the torque specifications of the fasteners.
When tightening the containment can bolts, use a star pattern torque sequence on the fasteners to ensure even
compression on the O-ring's surface. With Teflon O-rings, repeat this process several times, waiting between
retightening. This is necessary because the Teflon will cold flow and require a certain amount of time to properly
seat. Continue the process until the bolts no longer require retightening.
