Скачать или смотреть Nelson P200 4" flange mount Fast-reverse big gun

here's my P200 again running with a .90/.95" ring nozzle. using my phone tripod to film today. it gets good range for my subpar setup. reverse is nice and slow as well. enjoy!

According to Nelson's performance chart on the SR200 (same gun but slow reverse). I am not using a standard Nelson nozzle in this sprinkler. According to their specs, the smallest ring nozzle is a 1.29". You are required to have 230 GPM output at 50PSI and you get a radius of 163 feet.
The nozzle I am using is a fender washer. The hole in it would be similar to a .90"/.95" So i'd say at 40PSI I'm getting about 150/175 GPM for a radius of 125/135 feet. This is just a guess due to me using a smaller than standard nozzle due to my pumps not being able to support higher pressures with nozzles bigger than .97" ring (next to smallest for Nelson 150). The P200 can take a 1.05" taper bore but I believe that will not work the best due to it being too much for my 2 pumps.
With the original 1.56" ring nozzle this came with, it could get about 350GPM at 50PSI for a radius of 185 feet.
