Brand: Hunter Industries SKU: PGP-ADJ
Product Overview
The Hunter PGP-ADJ is a 4-inch pop-up gear-drive rotor with an adjustable 40- to 360-degree arc and a 3/4-inch female NPT inlet. This Big Frog Supply configuration is the standard no-check-valve version. It is designed for residential and light-commercial turf areas that need longer-range coverage than a conventional spray sprinkler while allowing the watering pattern to be adjusted for corners, property edges, irregular lawn shapes, or full-circle operation.
Hunter’s current PGP platform supports 27 nozzle choices across standard red, standard blue, and gray low-angle families. Depending on the installed nozzle and operating pressure, Hunter publishes an approximate radius range of 22 to 52 feet and a flow range of 0.5 to 14.1 GPM. Recommended pressure is 25 to 70 PSI, with an operating range of 20 to 100 PSI. Standard nozzles use a 25-degree trajectory, while low-angle nozzles use a 13-degree trajectory.
Through-the-top arc adjustment and the QuickCheck arc mechanism simplify field setup. The factory-installed rubber cover protects the adjustment area and provides a finished surface at grade. Because this standard configuration does not include a drain check valve, use an appropriate optional check-valve solution or a different factory model where low-head drainage control is required.
