PRODUCT OVERVIEW

PGJ...The Gear-Driven Answer for Medium-Sized Areas
The PGJ rotor has been developed to ll the void of the “mid-range” area in todayʼs landscapes: spacings 18' to 37' (4.6 to
9.1 m)…hard-to-t sites that are too large
for sprays yet too small for traditional rotary sprinklers. In essence, the PGJ has
been designed as a “PGP junior,” offering all the features and benets of our top­selling rotor, for use in small areas.
Offering greater efciency in the appli­cation of water for slopes, medians and conned areas, PGJ eliminates wasteful runoff and puddling often associated with multiple-row spray head installations.
PGJ...The Ideal Alternative to Spray Heads
The PGJ can be zoned together with other Hunter rotors, allowing areas that would typically use spray heads to be zoned together with PGP or I-20 rotors.
The PGJ saves installation time and material costs in narrow areas typically reserved for sprays. Less trenching, fewer piping connections, less lawn disruption are all important labor saving benets. With the PGJ, more sprinklers can be connected to the same zone, reducing the number of valves and controller stations.
PGJ Rotors
Hunter has always made it a point to listen to the comments of those in the eld when developing new products or enhanc­ing existing ones. In response to that input, a key feature of the PGJ is exactly what so many have been asking for—a protec­tive rubber cover that combines strength (to protect the inner workings of the head) with safety.
One of the hottest PGJ features is a radius adjustment screw with a hex socket and straight slot that allows for quick and precise ne tuning of the spray, keeping water away from surrounding buildings, walkways and hardscapes.
PGJ...The Special Features Customers Require
With a wide range of pop-up heights, the PGJ can meet all your needs. The 4" (10 cm) is for normal grass heights, the 6" (15 cm) is ideal for areas with taller grasses or where mowing is infrequent, and the 12" (30 cm) is ideal for all higher plant mate­rial. There is also a shrub model that is ideally suited for use on a riser.
The PGJ has the proven reliability of its “big brother” along with the easy to adjust arc, ranging from 40° to 360°, wet or dry, popped up or down!
PGJ...The answer to your needs for a small economical rotor for your residential and commercial landscape and turf applications.

AND BENEFITS
Nozzles Fashioned After Those of PGP
Same great features, but crafted for smaller coverage
The full range of PGJ nozzles come on a convenient rack just like the ones for PGP. They also feature the same basic design, making them easy to install and remove. And theyʼre also large, making it easy to determine the ow rate. But, make no mistake, PGJ nozzles have been spe­cically created to handle the particular needs of the smaller areas for which PGJ was made.
Radius Adjustment
Adjust the radius and ne tune the stream of water with a quick and easy radius adjustment screw
Using the convenient Hunter wrench or either a hex or straight slot screwdriver, nozzle radius can be reduced up to 25%. The radius adjustment screw doubles as a positive means of retaining the sprinkler nozzle, making nozzle installation fool­proof.
Pull-up Socket
Simplies nozzle installation and removal
The PGJ is the only mid-range rotor that has a pull-up socket, making it easy to access the nozzle.
Protective Rubber Cover
Keeps debris out and keep play areas safe
Just like the PGP, the PGJ rotor includes an integral rubber cover that won't come off. The cover serves a dual purpose, being solid enough to protect the internal adjust­ment mechanism and forgiving enough to provide safety to those may come in contact with it on the eld of play.
Compact Body and Small Exposed Surface Area
1 " (3 cm)–out of sight, out of mind!
The PGJʼs small exposed diameter hides from small children and vandals. It wonʼt detract from the beauty of the landscape.
40°-360° Adjustable Arc
Easily adjusts from the top of the sprinkler—up or down, wet or dry
For fast and efcient arc adjust­ments, the PGJʼs versatility allows you to put the water where you want it, without get­ting areas wet that should stay
dry. Easily ne-tune the precise setting you need with the same 4:1 ratio as the PGP.
Plus (+) and Minus (–) Symbols
Show the way for quick arc adjustment
The plus and minus symbols, on top of the sprinkler, make arc adjustments easy to understand.
Proven Reversing Mechanism
The industryʼs best for reliable directional change
The three spring reversing mechanism has given us the consistent directional change that reliable operation requires!
Single Thread Body Cap
Extra strong, yet easy to service when necessary
The single thread body cap and body top

withstand burst pressures in excess of 200 PSI (13.8 bars; 1379 kPa). It also allows for fast and easy servicing, if necessary, of the super large lter screen.
Proven Gear Drive
Matches the superior reliability of time-tested PGP drives
The PGJ is in essence a two-thirds scale version of our proven PGP rotor. It uses the same continuously improved gear drive design rst introduced over ten years ago, ensuring reliable operation.
Super Strong Retraction Spring
Provides positive retraction every time!
The PGJʼs spring is stronger than any of our competitorsʼ.
Variable Stator
Keeps rotation speed consistent regardless of nozzle size or pressure
With the variable stator design there is no need to adjust or change the stator “bypass setting” on the PGJ. Now even better than ever, the variable stator is more dirt tolerant, providing years of reliability. No matter what nozzle or variable pressure you may have, there will always be a con­stant rotation speed of the sprinkler across a wide range of pressures.
Heavy Duty Riser Seal
Stops wasteful excess “ow-by”
Hunter has taken the time-proven design of the PGP riser seal and used that as the inspiration to craft one specically for the PGJ. As the sprinkler pops up, the PGJʼs large sealing surface prevents wasteful ow-by. And, when itʼs retracted, it keeps debris from entering the seal.
Extra Large Screen
3 times the size of our leading competitorʼs
The huge screen with 30 mesh size can catch a large amount of debris, maintain­ing sprinkler operation and preventing nozzle clogging.
Drain Check Valve
Saves water, reduces liability
The drain check valve feature is optional in all pop-up models. The check valve will hold back water pressure from up to 7' (2.1 m) of elevation change. A “V” on the rubber cover indicates that a drain check valve has been factory installed.
Swing Joint*
For easy installations and retrots
A timesaving, versatile, heavy-duty swing joint to get the sprinkler height and posi­tion just right in mere seconds. It allows for use of a check valve on 6" (15 cm) and 12" (30 cm) models (a side inlet access wonʼt allow a check valve to work, but a bottom inlet access, with the addition of a swing joint, allows the check valve to function and give the user “side­inlet” versatility). The swing joint has swivel ells on both ends for added versatility. Install the swing joint vertically or horizon­tally with a twist of the wrist. The swing joint also protects lateral piping from downward forces exerted on the sprinkler by heavy equipment, providing a reliable, exible connection.
Reclaimed Water Versions
Easy identication when using reclaimed water for irrigation
Purple is the recognized color for irriga­tion components using reclaimed water. The PGJ can be ordered with a purple rubber cover permanently attached so it will meet the needs of identication stan­dards. The drain check valve is standard on all reclaimed water versions.
