NOTE: If the pump has the optional o-ring sealing option
(available on 184 and 215 frame pumps only), install the
o-ring (item 8B) in the groove in the motor adapter (mo-
tor end). Use small amount of petroleum jelly (or silicone
grease on EPDM o-rings) to help hold the o-ring in place.
Place the motor/drive on a flat surface with the drive and
motor face hanging over the bench surface. Secure the mo-
tor to the bench.
Firmly grab the pump and slide over the outer drive magnet
until the motor adapter is seated in the rabbet of the motor
(184TC) or the motor adapter flange. The last 4-5" (10-12 cm)
will have strong magnetic attraction between the pump and
outer drive magnet. See figures 6 and 7.

NOTE: The clearance between the motor adapter and
drive magnet is tight (about .010"/.254 mm).
6. Secure the pump to the motor using (4) 1/2" socket head cap
screws, lock washers and flat washers (items 14, 15, 16). Use
3/8" Allen wrench or 3/8" hex socket on universal joint. See
figures 8 and 9.

Rotate the motor fan to ensure that 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 may be used as additional support for the motor feet.

Only qualified personnel trained in the safe installation and
operation of this equipment should install the motor. Install the
motor according to National Electric Code, NEMA MG-2, IEC
standards requirements and/or applicable local electrical codes.
The voltage and frequency variations of the power supply should
never exceed the limits established in the applicable standard.
Prior to connecting to the power line, check nameplate voltage,
rotation connection and ensure proper grounding. Sufficient
ventilation area should be provided to ensure proper operation
and cooling of the motor. The motor must be installed with a
suitable overload protection circuit. For three phase motors it is
recommended to install a phase failure protection device. Down-
load the motor manual from the specific motor manufacturers'
website for additional information concerning motor installation,

Wire the motor for clockwise rotation when facing the fan end of
the motor.
the pump is full of liquid or damage may occur even if the motor
is "bumped" to check motor rotation direction.
Check all electrical connections with the wiring diagram on the
motor. Make sure the voltage, frequency, phase and amp draw

CAUTION: The NPSH available to the pump must be
greater than the NPSH required. NPSH available should be
two feet (.6 meters) greater than NPSH required.
Install the pump as close to the suction source as possible.
Support the piping independently near the pump to eliminate
any strain on the pump casing. In addition, 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.
The suction line should not have any high spots. This can
create air pockets that can reduce pump performance. The
suction piping should be level or slope slightly upward to
the pump.
If flexible hose is preferred over pipe, use a reinforced hose
rated for the proper temperature, pressure and is chemically
resistant against the fluid being pumped.
The suction valve must be completely open to avoid restrict-
ing the suction flow.
When installing pumps with flanges, we recommend use
of low seating stress gaskets such as Gore-Tex or Gylon
(expanded PTFE).
CAUTION: Do not operate the pump to check rotation until
