ASSEMBLY Of COUPLING
Series MD2– A4 / A9 Coupling
DANGER!
follow these directions exactly to avoid injury
to self or damage to the pumping unit. Be care-
ful to keep inner and outer magnets at least (1)
foot apart until step 5. Do not engage the mag-
nets in any other fashion.
CAUTION !
Do not place fingers onto front of pump mount-
ing flange. Align canister into bore of bracket
and gently slide in. When magnets start to en-
gage, the unit will finish engagement on its
own very rapidly. Make sure fingers are not on
the front of the pump (see figure 20).
4. Finish the assembly by securing the pump to the bracket
(See Figure 20). Check that the pump rotates freely by
spinning the motor fan blades or bearing carrier shaft.
1. Inspect the magnets for any steel objects, which may
be attached. Remove any foreign material. Locate the
outer magnet assembly per dimension (See Figure 19).
Apply Loctite and tighten the 2 setscrews onto the motor
or bearing carrier key & shaft.
2. Mount the coupling bracket to the motor (or bearing
carrier) and secure with 4 capscrews (Figure 20).
Carefully reach in and rotate the magnets by hand to
make sure there is no interference. If rubbing occurs
check the dimension in Figure 19 or contact the factory.
3. Check to make sure the pump rotates freely by turning
the inner magnet assembly. Inspect the magnet to make
sure it has not picked up any foreign particles, which
could damage the pump. Make sure the canister O-ring
is in good condition and in place. Place the canister onto
the pump and press on until the canister is in contact
with the pump mounting flange.

Be certain that the driving means (motor, tur-
bine, engine, etc.) has been “locked out” or
made non-operational so that it cannot be
started while work is being done on pump.
