A 220v pump motor will draw less current or amperage than the same pump that operates on 110v, so you would be better off with a 220v unit. Not knowing what your drawdown level is, is a disadvantage, but I would use a 1/2 hp 5 gpm unit rather than a 10 gpm unit.
If you have to use a safety rope to get your pump out, you should have used better pipe to begin with. Hang the pump on schedule 80 pvc or 160 psi poly, use a pump with stainless steel discharge head and be sure to use a stainless male X insert adapter with double stainless steel clamps to attach the pump to the pipe. Do not use brass with stainless! Warm the pipe with a torch and push it over the insert fitting, do not put it on cold or use a lubricate to help put it on!! Depending on which Loc Tite you use, it may not be rated for potability, instead use a Teflon paste of Rector Seal.
