12v transfer pump needed  RSS feed

Hello All,
First post from a real noob--
here goes-we are on the grid, and want to retrofit our existing water well over to solar.

Would like to pump from water well, to storage tank, (about 60' static) (storage, and pressure tank will be at top of well head) In a pump house, Then pump to pressure tank, then to home a 1000' away--doing it right now on AC. (Just no storage tank right now)-just to pressure tank then home about 40' rise to home. ( pressure tank set up 50# to 70#). Pipe to home is 1 1/2”. (It all works great)

At pump house, I would like to use 2-255w panels, powering only the solar pump (Grundfos 11)

Then to keep all my panels the same, another 255 watt panel run through a solar charger to a 12 volt battery-to a (12v transfer pump) to move the water from the (storage tank-1000 gal) to pressure tank. Pressure tank, and storage tank are at same elevation.
We want the ability to have pressurized water day and night.

**All that said, I NEED a good transfer pump, that can pump into the pressure tank at that pressure/head-(50-70#)--do not mind spending the money,-but it just seems that the 12v transfer pumps are terribly expensive, and very intolerable to dirt. (would like not to have a filter to worry about) have 10 mic. filter up at house.

Any input will be greatly appreciated,
Rocky in NM

From what I understand, your just looking for a pump to pump from the storage tank into the pressure tank correct? Your search will be easier if you use the keywords "booster pump" Backwoods solar and a multitude of other companies sell booster pumps. I have not purchased mine yet but Im looking heavily at the the 24 volt shurflo.

booster pumps

One thing you might not realize is most panels in the wattage your looking at, are 24 volts panels, and while it is possible to take 24 volts and charge a 12 volt battery, it requires an expensive charge controller in the 500 dollar range. The cheap ones will do 24 or 12, but the panels must match the battery bank.

I was convinced I was going to install a grundfos, but I did not. I went with a simple pump, I encourage you to check it out. I used it as a hand pump for awhile but now I use it with the 24v version of the motorized.

simple pump

Edited for this comment:

I would think you should not have to worry too much about dirt entering the pump. Most particulates will settle out in your storage tank, as long as your not pulling from the very bottom of the tank and you conserve water, there should be enough time spent in the storage tank to allow settling

I was going to use the single 255 watt panel to charge the 12v battery through a (solar charger/controler)-all 12v
I will run the Grundfos off 2-255 watt panels @ 60vdc--me thinks?? (all 3 panels the same size) makes my rack for me, more simple---

Got ya on booster pump terminology, that said--I just need to overcome the (head) pressure of the pressure tank (50-70#)
thanks for the reply--Happy Thanksgiving--Rocky
