Pumping from an open Well

I want to pump water from a 20 foot deep open well in NH and supply a 200 foot hose with one lawn sprinkler. Can someone recommend the best portable 120 volt reliable pump for us to use?

Tough question. Unless you use 3/4-inch inside diameter, you will lose a great deal of pressure through a 200-foot hose, even to run a single hose-end sprinkler. Also, a 20-foot lift is on the very edge of the performance capability of a pump.

In terms of what will actually work, it's also important to know the diameter of the well shaft. (is it a well point, or a standard 4-inch shaft, or a hand-dug 'wishing well' with stone walls and a bucket on a rope)

Since drawing water from the shaft will almost always lower the water level, you may actually require a "deep well" jet pump, in order to have anything both reliable and portable.

Thank you again.
It's a hand dug wishing well - we think it's 20 feet max. We will measure the depth.
We plan to sink the water inlet to near the bottom (with screen of course).
I'll let you know how it goes.
We are thinking of trying a 1/2 hp portable pump and see what happens . . .

You'll need a foot valve on that suction line.
