How to Read the Hunter PGP Nozzle Chart

1. Nozzle Number:

The nozzle number corresponds to its output size, a higher number means a higher flow rate and larger water throw.

2. Pressure (PSI):

Measured in pounds per square inch, it affects how far the water is sprayed. Ideal operating pressure for most Hunter PGP sprinklers is 30–50 PSI.

3. Radius (Feet):

This shows the maximum reach of the spray. Adjusting pressure or arc angle can slightly modify this value.

4. Flow (GPM/LPM):

Indicates how much water passes through the nozzle. Selecting consistent GPMs across zones helps ensure even watering.

5. Arc (°):

The spray pattern angle can be set between 40° and 360°. Wider arcs distribute water more broadly but reduce precipitation rate.

6. Precipitation Rate:

This represents how quickly water is applied, measured in inches per hour. Lower rates are ideal for clay soils, while higher rates suit sandy soils.

Choosing the Right Nozzle for Your Landscape

Selecting the correct Hunter PGP nozzle depends on several factors:

Water Pressure: Match the nozzle flow to your system’s pressure to avoid misting or poor coverage.
Zone Size: Larger areas benefit from higher numbered nozzles for extended reach.
Soil Type: Sandy soil may require faster precipitation, while clay needs slower, more even watering.
Plant Type: Turf lawns typically need uniform distribution; shrubs may need customized arc angles.

By using the nozzle chart, you can easily plan irrigation zones with matched precipitation rates to prevent overwatering or dry spots.

Maintenance and Adjustment Tips

Check for Clogs: Clean nozzles regularly to prevent reduced spray or uneven distribution.
Adjust Arc and Radius: Use the Hunter adjustment key to fine-tune your sprinkler’s spray angle and distance.
Monitor System Pressure: Fluctuating pressure can alter flow rate and radius, affecting performance.
Replace Worn Nozzles: Damaged or old nozzles may cause leaks or irregular spray patterns.

Proper maintenance ensures that your Hunter PGP sprinkler system operates efficiently for years with minimal water waste.

Benefits of Using the Hunter PGP Nozzle Chart

Improved Water Efficiency: Ensures each zone gets the right amount of water.
Consistent Coverage: Reduces dry spots and overwatered patches.
Easy Planning: Helps match nozzle performance to system pressure.
Cost Savings: Reduces water bills and maintenance needs through efficient irrigation.

Final words

The Hunter PGP nozzle chart is an invaluable guide for optimizing irrigation system performance. By selecting the appropriate nozzle based on pressure, flow, and radius data, you can ensure consistent watering and maximum efficiency.

Whether you’re managing a small home lawn or a large landscape, using this chart simplifies sprinkler setup and improves water distribution dramatically.
