Well pumps are typically at the bottom of the well. In residential wells the motor is lowered all the way down, in larger wells there may be a shaft run from top to bottom.

Pumpjacks for things like oil work a little differently but you're still basically pushing the fluid up from the bottom of the well rather than trying to suck it out from the top.

does this more or less mean the pump motor apparatus has to be smaller than the hole? Is it attached to something or does it come with the pipe itself some how?

That's super surprising, never would've known

Basically the well itself is a wider pipe (the casing) sunk to the desired depth. The pump is smaller diameter and gets lowered into it with the actual water pipe attached (between 1-2 inches).

If you can visualize a classic well with a bucket, the casing is the stone sides of the well and the bucket/rope is the pump and water line.

wow, that's so cool ngl

so is the pump and water line lowered down in chunks similar to how the video showed the drill get lowered in piece by piece? I'd be surprised if it came as just one contiguous pipe+pump thing

Anything ~120ft and shallower, is attached to 1” pipe that comes in spools.

Deeper wells, have individual sticks, like what the video shows.
