Hunter rotor pop-up sprinklers provide reliable, even watering for lawns, landscaped areas and larger areas of grass. Installed below ground level, the sprinkler rises when the irrigation system operates and retracts when watering is complete, leaving the lawn clear when not in use.
We stock a range of Hunter rotor sprinklers from the compact PGJ for smaller lawns through to the high-capacity I-25 for large landscape and sports applications. Each model uses interchangeable nozzles, allowing the watering radius and flow rate to be matched to the area being irrigated.
Access Irrigation have used Hunter sprinklers in our irrigation systems for many years. Their combination of reliable gear drives, simple adjustment and a wide choice of nozzles makes them suitable for both domestic and professional irrigation systems.
Which Hunter rotor sprinkler should I choose?
The main consideration when choosing a Hunter rotor is the distance the sprinkler needs to throw the water. Smaller lawns can normally be covered with the PGJ, while the PGP Ultra and I-20 are suited to larger gardens and landscape areas. For large areas of turf, the I-25 provides a considerably greater watering radius and flow.
| Hunter rotor | Watering radius | Flow range | Inlet | Adjustable arc | Typical application |
|---|---|---|---|---|---|
| PGJ | 4.3 – 10.7m | 80 – 1,000 l/hr | 1/2″ BSP | 40° – 360° | Small to medium lawns |
| PGP Ultra | 4.9 – 14.0m | 70 – 3,230 l/hr | 3/4″ BSP | 50° – 360° | Medium to large lawns and landscaped areas |
| I-20 | 4.9 – 14.0m | 70 – 3,230 l/hr | 3/4″ BSP | 50° – 360° | Large lawns and professional landscape irrigation |
| I-25 | 11.9 – 21.6m | 820 – 7,240 l/hr | 1″ BSP | 50° – 360° | Large turf areas, commercial landscapes and sports applications |
Watering radius and flow depend on the nozzle selected and the operating pressure available at the sprinkler.
Hunter rotor sprinkler comparison
| If you need… | Recommended rotor | Why choose it? |
|---|---|---|
| A compact rotor for a smaller garden lawn | Hunter PGJ | Lower flow requirements and a shorter watering radius make the PGJ particularly suitable for domestic lawns. |
| A versatile sprinkler for a medium or large lawn | Hunter PGP Ultra | A wide choice of nozzles and up to approximately 14m radius makes this a good general-purpose rotor. |
| A more advanced rotor for professional landscape irrigation | Hunter I-20 | Includes additional features such as FloStop™, a built-in check valve and options including a stainless-steel riser. |
| Long-distance watering for a large area of turf | Hunter I-25 | Provides a substantially larger radius and higher flow for commercial landscapes, large grass areas and sports irrigation. |
Hunter PGJ rotor sprinklers
The Hunter PGJ is the smallest rotor in the range and is particularly well suited to domestic gardens and smaller areas of lawn. Depending on the nozzle and water pressure, it can cover a radius of approximately 4.3 to 10.7 metres.
Its relatively low flow requirement also makes the PGJ useful where the available water supply is limited. The watering arc can be adjusted between 40° and 360°, allowing the same sprinkler to be used in corners, along lawn edges or for full-circle watering.
Hunter PGP Ultra rotor sprinklers
The Hunter PGP Ultra is a versatile rotor for medium and large lawns, with a watering radius of approximately 4.9 to 14 metres. A wide selection of interchangeable nozzles allows both the flow rate and watering distance to be matched to the irrigation system.
The PGP Ultra incorporates Hunter’s automatic arc return and non-strippable drive mechanism, helping protect the sprinkler if the turret is accidentally turned. The sprinkler can be adjusted between 50° and a complete 360° circle.
Hunter I-20 rotor sprinklers
The Hunter I-20 covers a similar radius to the PGP Ultra but adds features aimed particularly at professional landscape installations. These include a built-in drain check valve and Hunter’s FloStop™ system, which allows the water flow through an individual sprinkler to be shut off while the rest of the irrigation zone continues to operate.
The I-20 is an excellent choice for larger gardens, commercial landscapes and areas where additional durability and control are required.
Hunter I-25 rotor sprinklers
For substantially larger grass areas, the Hunter I-25 provides a watering radius of approximately 11.9 to 21.6 metres. Its larger 1″ inlet and higher flow capacity make it suitable for large landscaped areas, public open spaces and sports turf irrigation.
Because of its higher flow requirement, the available water supply and irrigation pipe size need to be considered carefully when designing a system using I-25 sprinklers.
Choosing the correct rotor nozzle
Hunter rotor sprinklers use interchangeable nozzles to control both the water flow and watering radius. Selecting the correct nozzle is therefore an important part of designing the irrigation system.
Start by establishing the distance that the sprinkler needs to cover, then select the nozzle that gives the required radius at the available water pressure. The flow rates of all sprinklers operating together on the same irrigation zone must then be added together to make sure the water supply and pipework can provide sufficient flow.
A Hunter sprinkler adjustment key can be used to change the nozzle and adjust the watering arc and radius.
Pop-up rotors or shrub rotors?
For lawns, the normal choice is a pop-up rotor. The sprinkler body is installed below ground and the riser lifts above the grass when watering starts before retracting when the system switches off.
We also supply PGJ and PGP Ultra shrub versions. These do not retract into an underground body and are designed to be mounted above ground, making them useful in planted areas or locations where a conventional pop-up installation is not suitable.
Planning a rotor sprinkler system
Rotor sprinklers should be positioned to give good overlapping coverage across the irrigated area. In most installations this means arranging the sprinklers so that the water from one sprinkler reaches approximately to the position of the neighbouring sprinkler. This helps produce more even watering across the lawn.
The number of sprinklers that can operate at the same time depends on their combined flow requirement, the available water supply, the operating pressure and the size and length of the irrigation pipework.
For a complete automatic system, Hunter rotors can be combined with Hunter solenoid valves, irrigation controllers and suitable underground pipework.

Frequently asked questions
What is a Hunter rotor pop-up sprinkler?
A Hunter rotor pop-up sprinkler is an underground lawn sprinkler that rises when the irrigation system is operating and rotates a stream of water across the lawn. When watering finishes, the sprinkler retracts below ground level. Rotor sprinklers are particularly suitable for medium and large lawns where a longer watering distance is required.
Which Hunter rotor sprinkler should I choose?
The main consideration is the distance you need the sprinkler to cover. The compact Hunter PGJ is well suited to smaller lawns, while the PGP Ultra and I-20 are suitable for medium and large lawns. For much larger areas of turf, commercial landscapes and sports applications, the I-25 provides a considerably greater watering radius and flow.
How far will a Hunter rotor sprinkler spray?
The watering distance depends on the rotor model, nozzle and water pressure. As a guide, the Hunter PGJ covers approximately 4 to 11 metres, the PGP Ultra and I-20 approximately 5 to 14 metres, and the I-25 approximately 12 to 22 metres. Always check the performance data for the selected nozzle when designing the irrigation system.
Can I adjust the watering distance of a Hunter rotor?
Yes. Hunter rotors use interchangeable nozzles to provide different flow rates and watering distances. The radius can also be reduced using the adjustment screw at the top of the sprinkler. For best performance, we recommend selecting a nozzle that naturally provides a radius close to the distance required rather than relying on excessive radius reduction.
Can the watering arc be adjusted?
Yes. Hunter rotor sprinklers can be adjusted so that they water only the required area. This allows them to be positioned in corners, along lawn edges or within larger areas of turf. Most models can also be adjusted to provide full 360° watering where required.
How many Hunter rotor sprinklers can I run at the same time?
This depends on the flow required by each sprinkler and the amount of water available from your supply. Add together the flow rates of all the sprinklers operating on the same irrigation zone and compare this with the available water flow. The pipe size and length must also be capable of carrying the required flow without excessive pressure loss.
How should rotor sprinklers be spaced on a lawn?
Rotor sprinklers should normally be designed with approximately head-to-head coverage, meaning that the water from one sprinkler reaches approximately to the position of the neighbouring sprinkler. The maximum spacing is 1.3x the radius, so sprinklers with a 10m throw could be spaced up to 13m apart. This overlapping coverage helps provide more even watering and reduces the risk of dry areas between sprinklers.
What is the difference between the Hunter PGP Ultra and I-20?
The PGP Ultra and I-20 cover a similar range of watering distances and use many of the same nozzle options. The I-20 adds features aimed particularly at professional installations, including a built-in check valve and Hunter’s FloStop™ function, which allows an individual sprinkler to be shut off while the rest of the irrigation zone continues to operate. The PGP Ultra is an excellent general-purpose choice for most garden and landscape irrigation systems.
