It was the wrong size.... I was hopeful.
With a help from a buddy and some ingenuity we got a new pump and pitless adapter in.
To start, I made a gantry from some spare wood and a cheap battery powered 3000lb ATV winch at the top. We got the top casing removed as well as three 20' sections of galvanized pipe and finally the pump itself. We found that the spool was very corroded inside the casing. Pounding it with a sledgehammer did not cause it to budge so I had to blast the outside with a propane torch and it finally let loose. I had no chance or desire to re-use the thing after the trouble it had caused me so we drilled a new hole for a slide in pitless adapter from the store.
The seal that I inquired about in a previous post did end up being too small but the original was in decent shape so we kept it.
I was originally going to go with Poly pipe but was talked out of it by the local well guy that was advising me. I was under the impression that PVC piping would be stiff and require threading each each section as the pump is lowered. Turns out you can prep the entire setup (pump, couplings, cables, pitless, t-handle) beforehand and lower it in with ease in a large arc.
Ended up going with a 1/2hp 2-wire Grundfos for the pump.
Thank you everyone for your insights and help. I'm sure I would have been in several $k given the situation with my deck, digging, and spool being stuck.
