It is probably a pitcher pump.
You may have to attach your own http://www to the second link. This site seems to put ... in place of much of the longer links.
Pitcher pumps can be attached to a point that goes down into the aquifer, or they can be attached to a drop pipe that goes into a shallow well. You will have to look at the pump to see where it comes apart so you can work on it. You may have to remove it from the well pipe. You will want to seal that connection when you re-install the pump.
If it is on a drop pipe going into the well, be sure you don't drop the drop pipe.
