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 top-

selling rotor, for use in small areas.

Offering greater efciency in the appli-

cation 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...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 mate-

rial. There is also a shrub model that is

ideally suited for use on a riser.

Hunter has always made it a point to

listen to the comments of those in the eld

when developing new products or enhanc-

ing existing ones. In response to that input,

a key feature of the PGJ is exactly what

so many have been asking for—a protec-

tive 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.

PRODUCT OVERVIEW

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.

PGJ Rotors

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 spe-

ci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 fool-

proof.

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 adjust-

ment 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 adjust-

ments, the PGJʼs versatility

allows you to put the water

where you want it, without get-

ting 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

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 con-

stant 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, maintain-

ing 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 posi-

tion 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 “side-

inlet” versatility). The

swing joint has swivel

ells on both ends for

added versatility.

Install the swing joint

vertically or horizon-

tally 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 irriga-

tion 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 stan-

dards. The drain check valve is standard

on all reclaimed water versions.

*Purchased separately

PGJ Rotors

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.

Arc Adjustment

Installation Height

1. Rotate the nozzle turret counterclock-

wise to the left stop.

2. Now, rotate the nozzle turret clockwise

to the right stop. This is the xed side

of the arc. The nozzle turret must be

held in this position for all arc adjust-

ments.

To increase arc:

1. Insert the key end of the Hunter wrench

into the adjustment socket on top of the

sprinkler.

2. While holding the nozzle turret at the

right stop, turn the wrench clockwise.

3. The wrench will stop turning when

adjusted to the maximum arc (360°).

Do not go past this stop.

4. Adjust to any arc between 40°-360°.

To decrease arc:

1. Insert the key end of the Hunter wrench

into the adjustment socket.

2. While holding the nozzle turret at the

right stop, turn the wrench counter-

clockwise.

3. The wrench will stop turning when

adjusted to the minimum arc (40°).

Do not go past this stop.

4. Adjust to any arc between 40°-360°.

Radius Adjustment

To decrease radius:

1. Turn nozzle-retainer/radius-adjustment

screw clockwise.

2. If smaller radius is desired install

smaller nozzle. This will affect precipi-

tation rate.

To increase radius:

1. Turn nozzle-retainer/radius-adjustment

screw counterclockwise.

2. If larger radius is desired, install larger

nozzle. This will affect precipitation

rate.

Precipitation Rate Adjustment

To increase precipitation:

1. Remove existing nozzle.

2. Replace with larger size.

3. Adjust radius.

To decrease precipitation:

1. Remove existing nozzle.

2. Replace with smaller size.

INSTALLATION &

MAINTENANCE

Nozzle Removal & Insertion

Nozzle Installation

1. Insert the plastic key end of the Hunter

wrench into the lifting socket of the

sprinkler and turn 90°. Pull the riser up

to gain access to the nozzle socket.

2. Using the hex key of the Hunter

wrench, turn the radius adjustment

screw counterclockwise to be sure it is

not blocking the nozzle socket opening.

If a nozzle is already installed, it can be

removed by backing out the adjustment

screw and turning on the water, or by

prying outward under the nozzle.

3. Slip the desired nozzle into the nozzle

socket. Note that the socket is angled

up 25° so that the nozzle range screw

threads directly down. Then tighten the

nozzle range screw. The arrow on the

rubber cover will always indicate the

location of the nozzle and direction of

the water ow when the sprinkler is

retracted.

Note: Undamaged nozzles are reusable.

Nozzle sets are also recyclable.

Cleaning the Filter Screen

Unscrew body cap and remove internal

riser.

1. If sprinkler has drain check valve,

remove with needle nose pliers.

2. With needle nose pliers, grasp large rib

(Fig. 3) on the inside of the screen and

pull rmly to remove screen.

3. Note the position of the large rib in

comparison to the date code, which is

located on the bottom of the riser.
