PC-S3000 — PART CIRCLE SPINNER
The Part Circle Spinner distributes
water to one side in an approximate
semicircle. It can be used to minimize
application on pivot towers or other
structures. The Part Circle Spinner
utilizes the 3TN nozzle of the conven-
tional S3000 spinner. The directional
control is provided by a ‘stream
deflector’ which is inserted between
the nozzle and the spinner body.
OPERATING SPECS:
•10-20 PSI (.7-1.4 BAR),
•#14-#40 3TN Nozzle,
•Mount on a rigid drop
assembly
The Part Circle Sprayhead has a 170°
arc setting to provide part-circle
operation for applications at the span
towers or offset drops or boombacks.
The PC-D3000 spray plate provides
stream definition similar to the spray
plate geometry of the #9493 Blue
spray plate. The medium grooves
and concave trajectory provide wind-
penetration and wide throw distance.

DESIGNING WITH PART CIRCLE SPRINKLERS
STEP 1: Plan the system with conventional full circle sprinklers.Plan the system with conventional full circle sprinklers.

Plan the system with conventional full circle sprinklers.
For Linears/Laterals select sprinkler spacing and determine the
nozzle size to deliver your desired application rate. For pivot
systems, planning should include a Sprinkler Package Chart. The
Part Circle Spinner will fit best in packages with sprinkler spacing
of 15 feet (4.5m) or less. The Part Circle Spray should be in
sprinkler packages with spacings of 11 feet (3.3m) or less. If the
part circle devices are to be mounted on boombacks, maintain
uniform spacing between all sprinklers. If the devices will be
mounted on conventional drops, a distance of 1 to 3 feet (.3 to 1m)
between the wheel and the closest sprinkler on each side is optimal.
STEP 2: Determine which outlets need modified sprinklers.Determine which outlets need modified sprinklers.

Determine which outlets need modified sprinklers.
Use the preliminary design to compare the distance to the tower
with the radius for each sprinkler. If you are working from a Sprinkler
Package Chart, adjust the listed Tower location for the wheel offset.
An offset of 2 feet (.6m) is common. Coverage diameter information
on other 3000 Series Sprinklers is available in the SELECTOR
software program or by contacting Nelson Irrigation.

The semicircular pattern of the Part Circle Sprinklers adjacent
to the towers should be oriented as close to perpendicular to
the main pipe as possible. On boombacks, they should face
directly away from the main pipe as shown in the diagram. On
straight drops, they should be adjusted so the edge of the
semicircle falls immediately behind the rear tower wheel. If
possible, orient adjacent part circles at opposite directions from
the pipe. This reduces the application rate.
ADDITIONAL CAUTIONS
It is important to mount Part Circle Sprinklers on rigid drops. Side thrust will cause extreme movement of flexible drops.
Part Circle Sprinklers cannot provide the whole solution to traction, rutting, or runoff problems. If you are trying to utilize
mechanized irrigation systems on steep slopes or heavy soils you should carefully consider all aspects of system design
and management that can contribute to reduced soil loading and application rate minimization. The distribution profile
of the Part Circle Sprinklers provides good overlaps with conventional sprinklers in most configurations. However, it is
likely that a system intended to minimize application at the tower will not achieve the high uniformity possible with a well
designed conventional system. For best results keep the spacing within the limits described above. Part Circle Sprinklers
can be used to minimize, but they will not totally eliminate, application on the towers or wheel tracks.
WARRANTY AND DISCLAIMER
Nelson Part Circle Spinners & Sprays warranted for one year from date of original sale to be free of defective materials and workmanship when used within the working
specifications for which the products were designed and under normal use and service. The manufacturer assumes no responsibility for installation, removal or unautho-
rized repair of defective parts. The manufacturer’s liability under this warranty is limited solely to replacement or repair of defective parts and the manufacturer will not be

Part-Circle Sprinklers can be installed in a
variety of configurations
BOOMBACKS
STRAIGHT DROPS
Installations on boombacks minimize the compromise in
uniformity that occurs when part-circle devices are utilized.
Installations on straight drops require careful adjust-
ment of the orientation.
