Based off the design of the world’s leading gear-driven rotor for
golf applications, the Precision Series Rotating Nozzle powered
by its proven planetary gear drive delivers wind-resistant,
multi-stream, multi-trajectory patterns. Both the full circle and
adjustable arc models deliver a radius range of 14 to 26 feet
with exceptional uniformity and outstanding close-in watering,
preventing the need to extend irrigation cycles to compensate
for brown spots. The consistent matched precipitation rate of
0.55 inches per hour helps meet the needs of tight water windows.
Features & Benefits
Gear-Driven
Precision Series Rotating Nozzles utilize a proven planetary gear drive,
variable stator and turbine to rotate the nozzle. The entire gear package
is contained in the area beneath the fine mesh filter screen. Particles large
enough to enter through the filter will exit out of the nozzle plate through
the multi-streams.

Fewer Models
Precision Series Rotating Nozzles reduce the number of models that need to
be carried in inventory. Two male-threaded nozzles and two female-threaded
nozzles are all that are required to cover radius range from 14-26 feet and
45-360°.
Matched Precipitation Rate of 0.55”/hr.
These nozzles deliver water more slowly and evenly than standard spray
nozzles. The precipitation rate of 0.55”/hr helps prevent the need to increase
irrigation run time so much that it is tough to apply all the water needed for
a given water window.
Consistent Speed of Rotation
The Precision Series Rotating nozzle is not dependent on system pressure like
competitive models. The gear drive mechanism delivers a consistent speed
of rotation regardless of system pressure and prevents product stalling at low
pressure. In addition, the gear drive allows for a wider operating pressure
range of 20-75 PSI.
Higher Output Torque
The gear drive develops an output power that is 10 times stronger than the
output torque of competitive units. This ensures positive rotation with no
slowing caused by environmental factors such as blades of grass or small
debris pushing up against the nozzle.
