Water-pump On A Well Point

I have a well-point ( 1 1/4") pipe where there is no electricity available. Can I connect a 2" semi-trash gas engine driven pump to the well point and be able to pump water out of the point?
 
You "can" if the water table is high enough for the self-prime (unless you prime the well pipe first), but trying to use that type of water pump to get water out of a well will be VERY hard on the pump. If you look at the specs of your 2" pump, it'll tell you how many GPM (gallons per minute). I promise you there is no possible way your well will put out anywhere near that kind of water volume. So the short answer is yes, you "can" do it, but expect to burn out the pump.

Don't know if I've ever seen a gas-powered well pump before, but I would think there are options available. ...What about an old-fashioned hand pump? I think they now make a rotary pump that is easier and faster (more GPM's). Just remember, you can only get as much water out of the well as what the well can supply.
 
I really doubt it, trash pumps are high flow, low suction head.

You want a low volume pump for 1.25 inch line that handles the suction head, and put in check valve.
 
Maybe, if the water table is high enough. We wash plastic points in with a trash pump. 1.5" pump I believe.

After the point is in, we pump them with the trash pump for a while to clean them out before hooking them up to the well pump. We can usually pull about 15 gpm out of an 1.25" point with a 3 hp trash pump.

It does take a few minutes to prime. Water table here is usually 10 to 15 ft down.
 
at 30 feet or more the suction will nt be enough to lift water at all. It depends on atmospheric pressure to push the water into the well and up into the pumps' vacuum. Most trash pumps or the like have suction more like 5 to 8 feet of suction lift. Old well pumps use pump rods and the pump leathers (seals) are at the bottom of the well, which makes suction irrelevant. Good luck. A jet pump will work in your application and could be powered by a gasoline motor. Jim
 
No. A 1" pump maybe if the water table does not get lower then 15-20 feet. I am watering some new plantings right now with my old Homelite Waterbug 1" pump. If I had known how handy this little pump would be I would of bought more. I think I got it at Central Tractor around 1990 for $79. This spring here in northern Michigan has been as dry as mid-August. I am thinking of buying a new spare 1" pump from China. Problem with a big pump is if you slow it down too much it loses its prime. We filled up a 250 gallon water-tank yesterday from a pond and did some watering with the little old Homelite. Worked perfect with a garden-hose.

Yes it will work. If you are using a sand point the water table is not extremely low. Did it for several years ran a 2" pump from harbor frieght on 2- 1.25" sand points. Irrigated a 1 acre truck farm. Worked very well.
 
Do you know how much water (GPM) the well is capable of? As I said before, centrifugal pumps don't like to run without water. It's the water that keeps the pump seals and impeller cool. Likewise, too little water isn't good either as it can or will greatly shorten the life of the pump.

If you need water in an area without electric, I would highly recommend getting a 12v pump or some type of hand pump.

How much water are you needing at any given time, and how often are you needing it?
