Deep well jet pump upgrade.

[Harmank70]

I currently have a simmer 3/4 horse deep well jet pump, with a 36 gal pressure tank. Looking for submersible pump recommendations. Would like to stick with 110 volt. Well casing is 4 inch. I assume a 3” pump would be best. Well is 65 foot deep. Any recommendations or things to consider when changing to a submersible?

4 inch well with steel casing?

https://aquascience.net/grundfos-5s...60164-3-stainless-steel-submersible-well-pump looks like it would do the job. https://www.waterpumpsdirect.com/Grundfos-Pumps-96160164-Water-Pump/p80403.html

The 5SQ05-180 would develop higher pressure, but the The 5SQ05-140 is probably the better match.

I also suggest a 3 inch flow inducer if well is 4 inch or bigger. Construction info available.

Yes, the casing is steel.

Is there a disadvantage to going with the higher pressure pump? Is overkill better? Would like to get 60 psi pressure if possible.

While any regular 4" pump will fit in 4" casing, the 3" SQ pump is pricy but has more room to fit.

I would use the 10SQ05-200 and a PK1A control kit.

Flow inducer construction and 3 inch pipe selection:

https://terrylove.com/forums/index.php?threads/lets-talk-inducer-sleeves.78342/#post-570428 is one of the threads that describes flow inducer construction. There are more choices, and putting "inducer" into the search box will turn up more.
