7. For NEMA 56C and 145TC frame motors:
Install o-ring (item 8E) in the groove on the back of the
motor adapter (item 8D). Use petroleum jelly to hold the
o-ring in place during installation. Note: 184TC and metric
adapters do not use this o-ring. Install the pump end on
the motor/drive magnet assembly. With the motor facing
upright, align the pump feet so that the motor feet and
pump feet are on the same side.
Tip the pump end at an angle (discharge is approximately
45º) so that it is just touching the edge of the outer
drive magnet assembly. See figure 8.
Carefully lower the pump onto the drive magnet assembly
by tipping discharge forward to 90º and dropping straight
down. The last 3-4 inches (8-10 cm) before the pump
reaches the motor will have STRONG magnetic attraction
between the pump and outer drive magnet assembly.
8. Secure the pump to the motor with (4) 3/8" bolts, lock washers
and flat washers (items 15,16,17). See figures 9 and 10.
NOTE: Apply anti-seize compound on threads of bolts.

NOTE: B5 flange motors will require customer supplied hard-
ware. B5 pumps with 100/112 frame do not include a pump
foot.
9. Rotate the motor fan to ensure there is no binding in the
pump.

Section II - Installation
Mounting
Pump foot should be securely fastened to a solid foundation.
If the pump was received with plastic shipping shims, these
shims may be used as additional support for the motor feet
(though not required).
Piping
CAUTION: The NPSH available to the pump must be
greater than the NPSH required. Filters, strainers and any
other fittings in the suction line will lower the NPSH avail
able and should be calculated into the application.
•
Install the pump as close to the suction source as
possible.
•
Support the piping independently near the pump to elimi-
nate any strain on the pump casing. Also, the piping
should be aligned to avoid placing stress on the pump
casing.
•
The suction side of the pump should be as straight and
short as possible to minimize pipe friction.
•
Keep bends and valves at least ten pipe diameters away
from the suction and discharge.
•
The suction line should be at least as large as the suction
inlet port or one pipe size larger so that it does not affect
the NPSHa. Do not reduce the suction line size.
•
The suction line should not have any high spots. This can
create air pockets. The suction piping should be level or
slope slightly upward to the pump.
•
A check valve and control valve (if used) should be
installed on the discharge line. The control valve is used
for regulating flow. An isolation valves on the suction and
discharge are used to make the pump accessible for
maintenance. The check valve helps prevent the pump
against damage from water hammer. This is particularly
important when the static discharge head is high.
•
If flexible hose is preferred, use a reinforced hose rated
for the proper temperature, pressure and chemical
resistance against the fluid being pumped.
•
The suction valve must be completely open to avoid
restricting the suction flow.
