82 PNEG-720-G2 12" and 16" Series II Sweep
Do I want to buy a pivot or a standard sweep? What is the difference?
The following drawing (Figure 11A) is of a 16" pivot sweep head end weldment and a 16" standard
sweep head end weldment. There are very few differences between the two. The standard head
weldment has the female pivot tube welded to the drive end of the unit. Two (2) plate braces and one
pipe brace support this tube. The pivot head weldment has a lug welded to the underside of the motor
mount plate. This lug is for attachment of the sweep pivot rod assembly. There is a large hole in the
rear plate for the center support tube assembly to pass through. Next to the large hole is a slot that the
center support mounts to.

How complete is the Series II Sweep?
With the exception of a few electrical connectors, all components required to assemble your sweep
are included.
How level does my floor need to be for the sweep to operate properly?
The top edge of the sump hopper and the top edge of the “X” brace support must be level with the
floor. The floor must be level within 3/4" plus or minus, preferably less. Any high or low points must be
gradually sloped. The change in elevation should be no more than 3/4" over 60".
Where should the center pivot pin be located?
The center pin or pivot pipe must be in the center of the bin. If it is not, the sweep could hit the bin wall.
There should be between 2" and 14" of clearance between the end of the sweep and the closest
obstruction (bin wall, stiffeners, etc.).
How round must my bin be for the sweep to operate properly?
Diameter tolerances are limited by foundation limits and sweep operation as well as structural issues.
For 72' diameter and larger bins, the overall tolerance would be plus or minus 1-1/4" on the radius, plus
or minus 1" on 42'-66' diameter bins and plus or minus 3/4" on 30'-39' bins.
