1 acre in rotors
26 heads are 30 ft higher than the pump.
9 rotors per zone

Will this pump work or is it too much power?
Dayton 2hp-3ph 230v,9.6a

1.5" main or 1.25?

the only above-ground pump that is likely to fit your requirements is the Sta-Rite/Berkeley SSHM-2

You need 3 phase in Canada? Sized about right but not sure about quality.

i thought about the GT20 goulds irrigator.

i want some good pressure and flow on this job.
3 phase in Canada, yeah whynot. haha idk. I dont do many lake jobs.
it been such a dry year here

That Berkley 2hp looks really nice tho. specs look similar

how much three-phase wiring do you do - by no means should this be your first time

country kid
07-02-2012, 06:53 PM
if it was my house i would just get the 7.5 hp and do it in one zone

I hope you know the difference between 3 phase and 3 stage.

for one acre, your specs are overkill, unless you have some restricted time window

31Partcircle, 7 full
suggest zoning it for 12 or 13gpm?
for 7 zones @13gpm,
30ft elevation to last head.
would a 1hp off 120v do it?

best single-stage pump will be a Goulds J15S jet pump

What are you using for an intake screen and how are you keeping it off the bottom?

Buy local, support your local business's whenever possible.
Flint & Walling is out of Indiana and so was Franklin Electric.
It's alot easier for warranty too.

The local pump retailer should be able to spec it out for you to a T. You will probably need to know how long to your furthest head as well. I prefer submersible pumps, bc my damn customers can't remember to winterize it and then they have to figure out how to prime every year.

I'd float the intake in an inner tube in a lake situation. I pull from a shallow creek and I have my intake suspended in the dam.

It depends on the type of lake and where it's located. You can also make a swinging type float with PVC pipe that would look more professional. Paint it black.

I understand what you are saying though.

And chances are...if he's using this setup an inner tube wouldn't be much worse.

I'm gonna tell you that that clean lake will clog sprinkler heads.

Why not use a 4" well screen? They are like $40 and last a long long time.

The 3 horse 3 stage Flint and Walling pump will get you what you need and it comes in a 3 phase version, I have a couple and with brass impellors they last a long time

Certainly not the "only" pump.

went to the world of pumps today, they told me same thing as wet boots.
the goulds j15s jet
but also said a Berkley 1.5 will do the same with a smaller price tag.
going to go with the j15s

the Goulds pump will have an easier time holding prime, with it's inner diaphragm

With a 30-foot rise, you will lose some performance, so it's important to not fudge the numbers
