Shaft and Impeller Size

Flange-mounted and quick-clamp flange mounted
agitators need shafts and blades. See below
to determine the length of the shaft and the
recommended impeller diameter.

22" (56 cm)
22" to 36"
17N712
(56 to 91.5 cm)
*Recommended impeller blade diameter is generally
determined by taking the inside dimension of the
tank, drum, or vessel (T in Figure 1) and multiplying
by 0.35.
**Speed is limited by material viscosity and
tank diameter for 12" (30 cm) impeller. See
Finding the Proper Agitator Speed, page 9
To determine the shaft length ("A" in Table 4):
1. Find the distance from the bottom of the tank up
1/2 the impeller diameter (i.e., 2", 4", or 6") (See
0.5 D in Figure 1 ).
2. From that point, measure to the lid mounting
surface (L).
3. Add measurement in step 2 (L) to the length of
the bearing housing (5" or 127 mm).
Example: Shaft length "A" = L + 5 inches (127 mm).
