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. 

 
2.  All Brawn Mixers are shipped with the shaft and 

impeller(s) disassembled from the drive assembly. 

 
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.  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

 

2. 

Install mixer shaft and impeller(s) (refer to shaft and 
impeller assembly section).

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. 
 
 

SHAFT & IMPELLER ASSEMBLY

 

 
If an optional rigid shaft coupling is furnished, connect 
the mixer shaft and rigid driveshaft couplings by carefully 
engaging the shaft rabbeted faces and installing the 
mounting hardware.  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 
 
Proper hollow output shaft installation is shown in 

FIGURE 1, PAGE 3

 
1.  Inspect the shaft surface for evidence of damage 

and repair, if required, before installing the shaft into 
hollow output shaft or connecting to flanged 
coupling. 

 
2.  Attach the shaft collar (Item 5) to the mixer shaft 

(Item 4). 

 
3.  Place the key (Item 7) on the mixer shaft and slide 

the mixer shaft into the hollow output shaft on the 
gear drive (Item 1).
