Hunter PGP Ultra Gives You Unmatched Innovation with Powerful Dependability

The Hunter PGP Sprinkler Head raises the bar for rotor technology with powerful features developed over three decades of research, customer feedback, and lab testing.

Get an Irrigation Solution that’s Efficient and Impressively Silent

The PGP Ultra takes the foundation of the best-selling PGP Rotor and raises the bar with various new features developed over three decades of research, customer feedback, and lab testing. Among the most notable improvements are the Hunter PGP Ultra valve, a drain check valve that keeps lines from draining when the system is shut off, its non-strippable drive, and automatic arc return. These features work to allow the turret to be turned without causing damage. Other advanced features include 34 nozzle options with several radius choices and a headed slot and set screw. The diversity of the Hunter PGP Sprinkler Head offers system installers an array of efficient options on any site. For peak efficiency, choose the PGP-04 with an optional pressure-regulated body that reduces incoming pressures of up to 100 PSI to 45 PSI for water savings up to 25%.

Each PGP Ultra comes with an easy-to-install, square top rack of 8 standard nozzles and 4 low-angle nozzles. And optional racks of short-range nozzles, for the smallest of areas, are available, too.

Take on Any Issue in the Field with the Strength and Quality Only Hunter PGP Ultra Can Provide

We know the intricacies of installing and maintaining a properly functioning irrigation system are varied and require an extreme amount of hard work from you and your team. Take a look at how incorporating Hunter PGP Ultra can help make almost any issue you’ll see in the field a thing of the past.

Issue: I can’t adjust the nozzle retainer screw with debris inside the socket.

Solution: The PGP Ultra and I-20 rotors have a headed and slotted nozzle retainer screw, allowing the use of a small, slotted screwdriver or the Hunter wrench for easy adjustments as needed.

Issue: Water seems to leak from the lowest sprinkler after the zone shuts off.

Solution: The PGP Ultra offers a field-installable drain check valve that can replace the normal filter screen. The check valve is a good solution in relatively flat landscapes, helping to prevent low-head drainage.

Issue: I need to customize my irrigation system for perfect coverage.

Solution: Each sprinkler comes with a rack of eight easy–to–install, flat-top standard nozzles, along with four low-angle nozzles. Racks of 18–25' short-range nozzles and MPR (matched precipitation rate) nozzles with a radius of 25', 30', or 35' are also available.

Issue: Water leaks from under the body cap of my old PGP rotors, but the newer ones seem to be OK.

Solution: The no-flow-by PGP riser seal is made from a high-tech material introduced several years ago with flawless performance. All Hunter rotors are designed with a removable, replaceable wiper seal, so even an older head can take advantage of this innovative new material.
