Run water pump off long electrical run?

[grsthegreat]

Consider Solar and 12volt dc pump .Have rancher friend that did this after thieves kept stealing his water pumps for cattle

Thats ok for filling a trough, but it wont pump water 900 feet

The bigger question is how much rise is there from where the pump will be sucking the water from, and to where it will be discharging the water? The amount of lift, in feet, is all that matters with pumps. Decided on the size of a pump that you need to get the amount of water that you need where you will be watering, and then you can figure out what sized wire you will need to power it.

If you have a lot of lift, you will need a lot of power, and that can be a very expensive extension cord!!!

This was my first thought and is the crux of the issue...!

The elevation is about a 30 foot - 40 foot rise and I can do the math to calculate the PSI loss for pumping uphill and size the pump accordingly. I can also go with a larger water line to reduce friction over the distance. I can add a boost pump near where we actually need to irrigate so that we can increase the water pressure.

We are on a well but the river water is probably better (may have some nutrients) for watering the grass? We are going to irrigate a lot more area than the average home owner and my other thought was to not put the wear and tear on our well pump which is at the bottom of our deep well -- and expensive and difficult to replace. Sounds like it won't be an issue to power the pump as long as I go with a heavy enough gauge wire. That is good to hear!

What is the elevation difference between the river and the source of power??

ive even run a 2/2/2/4 aluminum urd direct burial wire to run a 30 amp 240 volt circuit over 1,200 feet with no issues. And 2/2/2/4 urd is real cheap compared to copper #4.

When I was a kid (50s) Grandad next door pumped water from creek uphill using a hydraulic ram. I'm thinking that's what the one question was. It used no electricity, the flowing water was enough power to operate the ram.
I'm sure it was 1000ft, my guess was rise was 60ft at least. He ran spring water into a large tank in his attic. From there gravity fed down to bathroom toilets and to outdoor spigots.
Drinking water was supplied separately from a well.

That would be cool. Never seen something like that.

ram pumps - YouTube

Many ram pump videos online. First one I saw was on Stoney Ridge Farmer's channel.

There are submersible pumps that can easily pump the distance and pressure you need. It is no different than having a 1000' deep water well. We do it all the time. Just need to know the horsepower and voltage to figure wire size. And no matter if you are getting water from a pond or a deep well the cycling on and off has always been the problem. Stop the cycling and you won't wear out your deep well pump. But if you still want water from the pond you need to stop the cycling from that pump as well.

If it was me, I might go to an electrical surplus place and get a couple of transformers. Bump it up and back down from 600Volts.
