Sorry. I meant to put that above, I was agreeing with you on pump flow because there won't be more than 4-5 heads per zone and I don't need to run more than 4 zones at once. So thats be 16-20 which would only be 1000gpms. Honestly I dont even need to run that much at once but id like to have the ability to

awesome, thanks for the help, i will give you a call sometime this week. what you're suggesting is exactly what i've been researching today. the pressure reducing valve sounds like a good idea, also, l plan on using hdpe pipe as well so that should help with the water hammer. the biggest heads i'll be running will flow about 50gpm's at 80-90psi. the smallers heads i'll be using i can dial down the pressure at the valve for that block if i need to. i think a 90psi system with a jockey pump and maybe 1 or two pressure reducing valves as the elevation drops sounds like a good idea.

the other thing im trying to figure out is how small of a pump i can run, the pump i was talking about is 2000 gpm which is more than a 6" csv can handle, and way  more than i even need. maybe i should run a 4" pump? i know its smaller than the main pipe size but once the main pipe is charged 4" should be enough to keep up with everything.

hey guys, im designing a new irrigation system for my golf course and im looking for some help. this is a very budget concious system. the system will be an electric valve and hydraulic head block system. The pump station will be at the highest point of the course, the farthest point from the pump station is 3-4000 feet in distance and about 100 feet in elevation change. the are 4-5 holes that are at the same elevation as the pump station, but most of the system is downhill of it. Im going to be running 6" main line. I'm trying to plan the best pump set up for me, due to it being so downhill, i dont feel i need a huge pump station as gravity will do most of it for me. the pump im eyeing is a 6" end suction centrifugal low speed pump that can flow 2000 gallons/min and is 30hp. im planning on making my own pump station, utilizing a CSV and a pressure tank, pressure relief valve and probably a nema 3r control panel. i guess my questions are if im using the right pump? when i've only got one zone turned on, or im using a quick coupler will the csv dial that big pump down enough or should i have a seccond jockey pump as well? the other thing i was wondering about is how to incorporate soft starting onto a pump.

thanks guys for any help, i really appreciate it.
