Rotor
ment or lowered on the riser shaft for cleaning,
thus keeping the benefits of a no flow-by rotor.
Heavy Duty Spring
Positive retraction in the harshest
conditions
Other manufactures skimp on expensive stain-
less steel by using a thinner grade and fewer
coils. Only the PGP rotor, with the strongest
spring in its class, can assure reliable retrac-
tion time after time, keeping the sprinkler out
of sight when not in use (as well as protecting
them from mowers and eliminating potential
injury hazards).
Drain Check Valve
Saves water: reduces liability
The PGP rotor line has an optional built-in
drain check valve in the PGP and PGS, which
can be factory installed. The
check valve is standard on all
12" PGH (30 cm) rotors. A
gray ring around the rubber
cover identifies models
that have the check valve
option. The PGP with the
check valve installed at the
factory is designed to hold back
water to a maximum of 10' (3 m) of elevation
change. This 10' of height is accomplished
by a stronger spring added to the head during
manufacturing. Hunter provides the PGP rotor
with a check valve because stopping low head
drainage eliminates washouts and wasted
water, and may also prevent accidents from
occurring and pests from showing up. Also,
due to water staying in the pipes, installers
may benefit from the reduction of potential
surge damage.
Check Valve Field Installation:
The check
valve feature can be added to PGP sprinklers
in the field by ordering Hunter part # 142300.
This field installed check valve will hold back
water to a maximum of 2 ft. (.6 m).
Large Dirty Water Screen
Puts an end to clogging
If dirty water is in use, the large filter screen
helps prevent clogging of the nozzle. The
screen is easily serviced without removing the
sprinkler body from the line.
3-Spring Reversing Mechanism
Reliability when itʼs needed
The three springs in the PGPʼs reversing
mechanism create a very sharp, crisp reverse
trip action generating precise control of the arc
stops. Just about every adjustable rotor on the
market has a 2-spring reversing mechanism,
which results in a somewhat soft, non-precise
reversing trip.
Integral Rubber Cover with Membrane
Covered Sockets
Keeps dirt out, permanently installed
A unique flexible membrane ensures
that adjustment sockets will
always be covered, thus protect-
ing the internal mechanism
from dirt and intrusion. Itʼs
also simple to increase or
decrease the arc settings
using the adjustment socket
symbols, while the handy
arrow provides immediate
recognition of direction of the
nozzle stream.
Ratcheting Riser Stem
Setting the right side arc-stop is much
simpler and easier
Always looking for ways to make the install-
ersʼ job easier and more cost effective, Hunter
has designed the PGP rotor family with a
ratcheting riser stem. When the right side
arc-stop needs adjustment, and unscrewing
the rotor case or removing the entire internal
assembly is not the answer, just pull-up the
riser stem (either wet or dry) and turn it in the
direction you require.
