PGP Ultra & I-20 PRB

Manufacturer: Hunter

The PGP Ultra and I-20 PRB are built to thrive in applications where high water pressure could otherwise lead to inefficient nozzle operation.

Radius 4.9 to 14.0 m

Flow 0.07 to 2.22 m³/hr

Flow 1.2 to 36.9 l/min

Inlet Size ¾" BSP

Pressure-regulated body (3.1 bar; 310 kPa) reduces high incoming pressure to increase nozzle efficiency (requires dynamic pressure differential: 1.0 bar; 103 kPa)
Part- and full-circle in one model for flexibility across landscapes and reduced inventory
Drain Check Valve prevents low-head drainage (up to 3 m of elevation)

Manufacturer part number: I-20-00-PRB

Features

The PGP and I-20 pressure regulated bodies will take incoming pressures of 3.5-7 Bar and reduce them to 3.1 Bar. The Hunter PRB rotors allow the nozzles to operate at peak efficiency, saving up to 25 percent more water. Having the pressure regulator in the body allows it to remain in place and functional even if the original riser is removed and replaced for service.

Key Benefits

Pressure-regulated body (3.1 bar; 310 kPa) reduces high incoming pressure to increase nozzle efficiency

Patented automatic arc return feature returns the turret back to the original arc pattern if vandalised; adjustable arc from 50° to 360°

Non-strippable drive mechanism is protected from damage if turned in the opposite direction of travel

Part- and full-circle in one model for flexibility across landscapes and reduced inventory

Headed and slotted setscrew allows radius adjustment with a Hunter wrench or flat-blade screwdriver

FloStop™ closes the flow of water from individual sprinklers, to change the nozzle or perform repairs (I-20 only)

Flat-top nozzles allow fast, easy insertion

QuickCheck™ arc mechanism for fast arc adjustment

Available stainless steel riser for extra durability

Drain check valve prevents low-head drainage (up to 3 m of elevation)

Advanced Features

Pressure Regulated Body (3.1 bar; 310 kPa)

Reduces high incoming pressure to prevent misting and allows nozzles to operate at peak efficiency. Lower pressure produces larger water drop - lets that fight the effects of wind.

PGP Ultra 10cm, I-20 10cm and 15cm

Stainless Steel Riser (PRB)

For unforgiving soil conditions, unpredictable climates, or heavy foot traffic, stainless steel with the I-20 model is the best choice.

Drain Check Valve (up to 3.0 m of elevation)

As air in the system piping can cause long-term damage to rotors and plumbing, the drain check valve keeps lines from draining when the system is shut off. This saves water, reduces liability, and increases system life.

Optional Reclaimed Water ID

Purple caps indicate where non-potable irrigation water is being used.

Automatic Arc Return

This patented feature returns the turret to the original arc regardless of where it is turned. This ensures vandal protection in any environment.

Non-Strippable Drive

The patented, non-strippable, vandal proof drive mechanism enables the turret to be turned without causing damage.

Part- and Full-Circle in One Model

Patented non-reversing 360 for part- and full-circle in one model, from 50 to 360 degrees.

Headed and Slotted Set Screw

Use a slotted screwdriver or the Hunter wrench for easier and simpler adjustments as needed.

FloStop® Control for I-20

FloStop closes the flow of water from individual sprinkler heads while the system is running. This is ideal for changing nozzles or turning off specific heads during maintenance and construction.
