PNEG-750-G2 16" Series II Sweep 131' and 135' Diameter 75
How large of an opening do I need for a standard flow (15000 BPH) center sump?
If installing a 16" standard sweep (non-pivot), the minimum recommended sump opening is 42" x 42".
If installing a 16" standard sweep with a pivot kit, the minimum recommended sump opening is
42" x 42". The cross brace (spider) is designed to fit a standard 42" x 42" sump, but the arms can be
cut by the customer to fit a smaller opening. The top of the sump center brace weldment must be
level with the top of the floor.
If installing a GSI supplied sump shell with collector ring, the opening must be 42-1/2" x 42-1/2" x 30"
deep for the 16" sweep.
The sump hopper supplied by GSI was designed with sufficient clearance around the collector ring
housing to allow grain to gravity flow through the hopper and be carried away by the material
handling equipment below it. 42-3/4" is the maximum opening size to allow rolling clearance for the
casters assembled to the head end jack. If the sump is made smaller, grain flow may decrease to an
unacceptable level.

The open area of this sump is misleading. The collector ring housing sticks down into the sump,
blocking off a portion of the flow. Also, the sweep covers about one quarter of the opening at the top.
We use 75% of the theoretical flow around the housing for the actual flow.
What intermediate sump spacing do I need? Why?
It is required to install the intermediate sumps on a maximum of 10' centers where the sweep will be
parked during storage. The first intermediate sump should be placed a maximum of 10' on center
from the center sump and the end sump should be no farther than 4' from the bin wall. The extra
sumps will help clean out the grain in front of the sweep, reducing the start-up load. Doing this will
save labor dollars and hours of work to dig out the sweep and will help the sweep during start-up. The
sweep is not designed to start-up when submerged in material. The sweep should be parked behind
the intermediate sumps with the sumps on the auger side of the sweep.
Do I need to clean out around the end of the sweep prior to starting it up?
Enough material must be removed from around the tractor drive and the screw drive units to allow
access to the motor/drive covers. Both the chain drive and the belt drive must be free of grain before
and during operation.
