Part Circle Impacts

Southwest Irrigation gives you the same rugged, heavy-duty construction and quality of our Impact Sprinklers with the flexibility of part circle performance.

The sturdy drive arm accompanied by the large impact surface allows for a consistent drive mechanism. The stainless steel arm and spring pin withstand even dirty water conditions, while its heavy-duty bearing contributes to a long life. Impacts are available with Nelson's famous FCN® Flow Control Nozzle to equalize flow rate under fluctuating pressure.
