Hunter PGJ Rotor User Manual

Trajectories
The nozzle trajectory is approximately 18
degrees. This is high enough to reach the
proper radius without being so high that it
is affected in windy conditions.
The PGJʼs interchangeable nozzles pro-
vide a wide and versatile range from the
optimum performance is based upon 40
PSI (2.8 bars; 275 kPa), dynamic operat-
ing pressure.
The average precipitation rate is
approximately .60" per hour (15 mm/hr)
for a 180° arc sprinkler. The actual pre-
cipitation rate may vary, and should be
calculated.

PGJ Rotors
Data represent test results in zero wind. Adjust for local conditions. Radius may be reduced up to 25%
with adjustment screw (this may alter the uniformity of the spray pattern). Optimum performance is at 40
PSI (2.8 bars/275 kPa). For information on testing standards and precipitation rate calculations, see Hunter
Irrigation Products catalog.
