Initial Inspection; Installation - Brawn BGM33 Operation And Maintenance Manual

3389 ~ 128 Avenue Holland, MI 49424

INITIAL INSPECTION

1. Upon receipt of your Brawn Mixer, check for possible
shipping damage. Report any damage immediately
to the carrier and to Brawn Mixer, Inc.
2. All Brawn Mixers are shipped with the shaft and
impeller(s) disassembled from the drive assembly.
In addition, the clamp or cup mount and any
mounting hardware for portable mixers are shipped
loose.
3. Storage: Mixers should not be stored near vibrating
machinery to avoid damage to the bearings. Store
mixers as packaged by the factory. For longer
storage periods, consult factory. If electric motors
have been subjected to humid conditions, check the
insulation resistance between phase and mass and
between the different phases. The resistance should
not be less than 100 megohms. If the resistance is
less, please consult the factory. If mixer is stored for
more than a year, the condition of the gear lubricant
should be checked before the mixer is put in
operation (see lubrication instructions).

INSTALLATION

[REFER TO ASSEMBLY / DIMENSION DRAWING]
Refer to the mixer installation / assembly drawing for
important mounting structure design, assembly,
mounting and dimensional data.
1. Model BGM portable mixers are designed with
handles incorporated in the mounting base. These
are intended for lifting of the mixer assembly.
2. For clamp-mount units, install the mixer drive on the
mounting structure and secure by tightening the
clamp screw.
 For fixed-mount and cup-plate mount mixers,
install the mixer drive on the mounting structure
and secure with properly-sized, Grade 5 or better
hardware. Torque the hardware as
recommended in TABLE 1.
3. Inspect the impeller bore and shaft surface for
evidence of damage and repair, if required, before
installing the impeller(s) on the shaft or the shaft into

the coupling. Install the impeller(s) on the mixer shaft
by carefully sliding the impeller hub over the shaft to
its proper location and tighten the set screws. It is
recommended that the shaft be spotted with a drill
point at the setscrew locations to prevent loosening
of the impeller(s).
4. Install mixer shaft [16] by inserting the end with
machined groove into the chuck driveshaft [14]. (It
is recommended that the mixer shaft portion
engaged in chuck driveshaft be coated with an anti-
seize compound.) Tighten setscrews [15] to secure
shaft.
 If optional rigid shaft coupling [25] is furnished,
connect the mixer shaft [28] and rigid driveshaft
couplings by carefully engaging the shaft
rabbeted faces and installing the mounting
hardware [26 & 27]. Be careful not to damage
the coupling faces or rabbets, as this can cause
excessive shaft run-out that will affect the life of
the mixer.
 2-D and 3-D depictions of these items are shown
in the front and back of this manual.

BOLT-TIGHTENING RECOMMENDATIONS:
Inadequately or improperly tightened hardware can
loosen, due to vibration during mixer operation. This can
result in reduced mixer life or damage to equipment.
Recommended torque values for tightening all in-tank
and mounting hardware are listed in TABLE 1. These
average torque values should be considered only as a
guide and not as absolute values.
