The impact sprinkler was a big part of what got us started. As Rotator® technology developed we replaced many of our impact sprinklers with new products. However these large 1" and 1 1/4" brass sprinklers are still running strong.
The sturdy drive arm of a Nelson brass sprinkler accompanied by the large impact surface allows for a consistent drive mechanism across a wide range of pressures and flow rates. The stainless steel arm and spring pin withstand even dirty water conditions, while its heavy-duty bearing contributes to a long life that cheap imports cannot replicate.
P65 sprinklers use a 7RN nozzle, and optional 7V vane to increase throw distance.
P85 sprinklers use a 8DRN nozzle, and optional 8V vane. The 8ADN (adjustable diffuser nozzle) is also available to customize the water application characteristics. They are available in low-angle models (designated by "A" in the model name) for end of pivot applications, as well as standard 24 trajectory for solid set applications. Single or dual nozzles models are also available.
