Pump Jacks
Pump jacks are essentially a windmill head mounted on the well pipe a few inches above the ground powered by a 1/2 to 1 hp electric motor via v belt. They are very reliable, but suffer the problems of windmills regarding pipe, cylinders, pump rods.

Advantage of 1/2 hp submersible for stock wells over all others!
1/2 hp submersibles are quite cheap for the ten to twenty years of reliable service. Many would say, I have no electricity at the site. Re: post on industrial grade inverter----with a 700 to 1000 watt solar panel, the inverter , you have all you need with the exception of two deep discharge 12 volt batteries. Compare costs of getting electrical power & monthly rates to solar, windmill and long term costs & reliability of the supply.
I have known several farmers who have gone from solar back to 115 vac submersibles.
Windmill wheel repair
When installing new blades or blade sections , always use some kind of locking material on nuts. I use silicon rtv. Check them periodically. Check head oil level every 3 months!! Very important for long life!!
Cylinder update
Warning: do not install new cylinders without disassembling & checking all nuts for tightness. Most I have checked either rod, leathers, or end caps needed tightening.
Also, don't use used cylinders even with new leathers if you have any doubt, go with new cylinder!!

Stock Watering ---Independent of Power Companies using 1/2 hp submersible
No windmills, no cylinder leather problems, no solar pumps requiring periodic filter cleaning, just a reliable supply of water. Submersible usually last for ten to twenty years. You will not get that reliability from any other approach!
Basic components:
1/2 hp pump--115 vac--no control box----$250
2400 watt, 24 vdc input, 120 vac output-----$600
2 12 volt deep discharge batteries -----$300
100 Watt solar panel--24vdc output---- $400 ( see buyers guide on this site)
Timer ---$100
Run pump 60 minutes for 400 gallon per day---ten minute segments --6 over day light hours to distribute load on battery. For less water per day, reduce run time accordingly. Pump output 7 gallon per minute.
For 200 gallon per day, run pump .5 hour. ( six 5 minute segments ) One hour run = 370 watt- hours discharge. 7 hours of solar output at 100 watts = 700 watt-hours input.
You have the flexibility of running for longer periods by utilizing a 1000 watt ac generator..
