Diaphragm well pumps and delivery

[Mike90250]

Isn't a diaphragm pump, a suction lift pump? Can you put one down a well hole ? Suction only works for about 20' down, then you reach the physical limits of suction,

ello. So I am trying to get more efficient in my energy usage for my water pumping. I have a 24v system and 24v batteries. I use a whole lot of water for agriculture stuff. Right now I have an ac pump running off inverter but it has to go. My well is low yield (2.7 gpm) but it never goes dry. It's 200ft but I don't know what the water level is.
I'm hoping to get by with about 1500 gallons a day. I want to use a diaphragm pump to pump around the clock. Couldn't find much for options. I think I'm going to use a nemo. It is only rated for intermittent duty so I will probably run a cycle timer on it. 30 min on, 5 minutes off. Any longer of a break and I wouldn't get the water I need. The nemo is 24v so it could plug into my batterys. If anyone has a better option it would be great to hear.

Also, I have some 12v delivery pumps for pumping out of my tanks. Small shurflow 3gpm. If I used a step down transformer to connect it to my 24v batteries, would it be wasting power when it is not in use?

Thanks!
