How can I pump water from a 2" casing???

**happymowing** · 10-26-2010, 12:13 PM

I have a 2 " casing that you used to hold an old duro piston pump. The top of the water is 35' and the base of the well is 65'. I am trying to find something that will produce enough pressure to water a garden and other outside applications. I have researched air lift pumps, submersible pumps, deep well jet pumps...but it seems that there is not one out there for a 2 " casing that gets decent pressure as well.

Any help would be greatly appreciated!!!

You're looking for a 1 hp pump, right? Two 1/2 hp or three 1/3 hp pumps hydraulically in series may give you the necessary pressure.

Also, you can probably get a lot of power for a small size from a pump that uses compressed air to spin the impeller, if anyone makes such a thing for wells.
Probably the only limit on power from such a pump would be the pressure rating of the supply hose.

The top of the water is at 35 ft. NO SUCTION PUMP will lift the water that far. You need a deep well jet pump or a small diameter submersible pump that you can drop into the well.

There are deep well jet kits that will work in a 2" well but you need a "packer" system that has one pipe going down the well and a seal at the bottom that allows water to flow in the annulus between the "down pipe" and the casing.

You could also use a cylinder pump such as the old windmill pumps that work with a rod going down the well. http://www.windmill-windmills.com/ho...mills-work.htm

A packer system would be your only option however due to the age of the well and internal corrosion I doubt that you can install a packer in this well. There is a 2" submersible pump manufactured but you need at least a 3" well casing.
A rod and cylinder pump wouldn't practically work in a 2" casing.
With all that said, I would say your only option on this existing 2" well would be a small 1/2" or 3/4" air line to near the bottom connected to a small 2 cfm or more air compressor. This would bubble/blow the water and air to the top of the ground or into an open top tank, then using a shallow well jet pump and possibly a Pside-Kick to supply pressure water to the garden. For safety of the pump you may also want to consider using a low pressure Square "D" pressure switch so that the pump would shut off when there is no water at the suction. All this may sound complicated but it's quite simple.
