Old 2" Well - Questions

[viperar15]

So I have an old 2" well at my house, installed in 1976 (pre-me and pre-me owning this house). I have lived here now 10 years. Have not had any problems (thank goodness!).

The 2" well is about 206' Deep.
It uses an old Shetler Pump (no longer in business, was built in Clio, MI).

Being this deep, I am told it is a deep well setup. Which seems different the any deep well setup I see today.

Going into the pump is about a 2" or 3" black flexible like tubing.... and inside that pipe is another pipe. So one is the water coming into the pump and the other is water pushed down the well for pumping.

I understand how the bigger 4 and 5" wells work with a 2 pipe system, but... how the heck does a system like this work with a 2" well.... and how does this pipe inside the pipe work/attach to the well? I haven't been able to find any images/documentation, etc online for a well like this. So... any help would be awesome in understanding this well.

Reason I am asking is that I would like to look at possibly replacing this pump with a better pump to get better water pressure in the house (though... I have thought about using a cycle stop valve as well.). If I replace the pump and with how old the well is... it probably doesn't make much sense to replace the pump if I don't replace the foot (assuming that after all these years, it may be slowly plugging up... though for the most part... I believe that I do get good pressure while the pump is running.

Thoughts? Ideas? Help? Images for how this is hooked up? etc, etc, etc!

Thank you!

The first 21 seconds of this animation shows a deep well with a single pipe jet system:

Search for packer jet pump water well to see how they work.

so... that is getting me in the right direction. starting to make sense. though I don't fully understand how I can attach a pipe inside of a pipe horizontally to a vertical well. I did find by chance, the patent document for the Shetler Pumps (http://www.freepatentsonline.com/4304526.pdf)

Attached in the image of what I understand to have. So it looks like the head of my well is underground, with a vertical to horizontal adapter (and more 2" pipe coming above ground), with a larger horizontal 2" pipe outside, and smaller 1.25" pipe inside of it... going to to pump.

Has anyone ever seen this? Is there a pump out there today that can handle this type of hookup? Is it even worth messing around with?

Here is a better example:

So I think I might finally be on to something here... though I won't be able to confirm till it warms up here in michigan and I do some digging... but...

From what I have been digging through in the vast of the internet, I believe I have the PJ Single Pipe Pitless Spool setup from Baker Water Systems.

You can see how the pressure pipe encases the suction pipe.
