1. Remove the piping to the ports and remove the
capscrews securing the pump to the bracket Support
the pump with an overhead hoist if possible. Use the
M10 x 120 capscrew in the bracket to separate the inner
magnet from the outer. (See Figure 12).
CAUTION !
Do not place your fingers between the pump
mounting flange and the face of the bracket.
Using extreme caution, pull the inner magnet
away from the outer magnet (see figure 9, page
7). If you do not completely pull the pump out
it will snap back and could pinch a finger or
hand. Once the inner magnet is removed from
the bracket be careful setting it down as it will
attract any iron or steel object.
2. The canister will contain some liquid, therefore use care
while removing from the pump and pull it straight off.
3. Remove the two 6mm buttonhead machine screws
and the set collar. Insert a brass bar through a port
between two rotor teeth and remove the locknut (See
Figure 13). Slide the inner magnet off the shaft. Do
not forget this is a very strong magnet. If further pump
disassembly is required, refer to Step 7 of PUMP
DISASSEMBLY, page 4.
4. Do not remove the O-ring unless it is bad, especially
if PTFE derivative encapsulated. If a new O-ring is
required, follow instructions in the ASSEMBLY section,
page 9.
5. You should be able to visually inspect the outer magnets
from the end of the bracket. If removal is necessary,
start by removing the (4) capscrews (See Figure 14)
and separate the bracket from the motor or bearing
carrier. Loosen the 2 setscrews on the outer shell hub
and slide the outer magnet assembly off the shaft. If
the unit features a bearing carrier, the bearings should
not require maintenance since they are sealed. If
necessary, disassemble by removing the single internal
retaining ring then press the shaft and bearings out of
the housing. Remove the external retaining rings from
the shaft to remove the bearings (Refer to Figure 7,
page 6 and Figure 15, page 9).
