Under higher pressure which head type has longer throw and higher uniformity?

• A. Rotor heads.
• B. Spray heads.
• C. Micro-sprinklers.
• D. Drip emitters.

Answer: (A)

Under higher pressure, rotor heads provide the longest reach and the most even distribution across the area. The water exits the nozzle more quickly, and the rotating action sweeps the water around, delivering it in a continuous arc. That rotation helps spread flow evenly, reducing dry spots and delivering a more uniform application as the head turns. Fixed spray heads don’t benefit as much from higher pressure because they shoot water in a single, non-rotating pattern, which can become uneven due to nozzle differences and wind, and their throw is limited by the nozzle design. Micro-sprinklers typically cover smaller distances, so their throw isn’t as long. Drip emitters are designed for low-volume, low-pressure delivery and do not provide any throw at all.
