SHAFT & IMPELLER ASSEMBLY

 

 
 
To install the impeller on the shaft, slide the impeller hub 
over the mixer shaft, place the hook key in position, 
lower the hub over the hook key and tighten the set 
screw. The set screw must seat in the countersunk hole 
in the hook key. Proper impeller mounting is illustrated in 

FIGURE 1

. If an axial flow impeller of bolt together 

construction is used, blades should be bolted to the 
bottom of the impeller hub ears as shown in

 FIGURE 2

START UP

 

 
1.  All units are lubricated before shipment. The 

lubricant level should be checked with the unit 
mounted in its correct operating position. Lubricant 
should be added or removed to bring it to the correct 
level. The catalog for the gear unit shows the oil level 
for various mounting positions. 

 
2.  Connect the motor in accordance with the motor 

nameplate. The motor starter should incorporate 
overload protection. Before operating the mixer, jog 
the motor and observe mixer shaft rotation. Proper 
rotation is clockwise, as viewed from the top, unless 
otherwise noted. 

 
3.  Check all bolts and fasteners for tightness. It is good 

maintenance practice to recheck all bolts after two 
weeks of operation and periodically thereafter. Refer 
to 

TABLE 1

 for recommended torque values. 

 
4.  Do not attempt to start mixer with impellers buried in 

solids or solidified liquids. 

 
 

 CAUTION 

Do not operate mixer with the tank empty or the lowest 

impeller submerged with less than ½ of the impeller 

diameter of liquid above it. Damage to the mixer and/or 

mounting structure may result.
