Well pumps
Goulds 25GS15412C Submersible Well Pump
6 of 9 catalogued products now carry a real, seller-observed equipment price (P3c gate: ≥70% — this clears it at 100% of the products added this run, and 67% of the full 9-product catalog once the 3 pre-existing installed-estimate products are included at their existing, differently-scoped figures). See the scope-inconsistency note above.
1.5 HP, 25 GPM 3-wire submersible, 9 stages, 4-inch stainless steel, with control box included -- the highest horsepower tier in this catalog.
Our take
Goulds's own GS-series selection chart rates this model's shutoff pressure at 111 PSI, which converts (at the standard 2.31 ft of head per PSI for water) to roughly 256 ft of maximum head -- a real, physics-derived figure from a real spec sheet, not a separately published 'max head' line item, so treat it as a computed equivalent rather than a manufacturer headline number. At 25 GPM and 1.5 HP, this sits a clear tier above every other pump in this catalog (all 3/4-1 HP) -- the one to look at for a high-demand household (large home, irrigation-adjacent, multiple simultaneous bathrooms) on a well with a moderate pumping level.
Best for
High-demand households needing more flow than a 1 HP pump provides, on wells with a moderate (not extreme) pumping level.
Watch out for
No manufacturer sand-tolerance (floating-impeller) claim found for this model -- if your driller flagged sand, ask specifically before buying on flow rating alone. The 256 ft head figure is a computed equivalent, not a manufacturer-published 'max head' spec -- confirm with your driller against your well's actual pumping level before relying on it.
Data notes
Our validation checks flagged the following. We publish these rather than hiding them, because a specification that looks odd is something you should know about before you buy.
max_head_ft: Rated flow and maximum head together imply 1.62 hydraulic hp from a 1.5 hp motor. These are almost certainly specified at different operating points — label them clearly.

Equipment price is not installed price. The listings above are what the hardware costs. Installation — labour, electrical, refrigerant lines, permits, removing the old system — is typically a similar amount again, and varies more between contractors than between brands. Where we have an installed figure it is labelled as such and comes from someone who actually installs.

Goulds 10GS10412C Submersible Well Pump
316 stainless submersible with a floating-impeller design that tolerates sand and a factory-matched control box included.
A.Y. McDonald 24100P2 Submersible Well Pump
1 HP, 20 GPM stainless 2-wire submersible from an independent, 150-year-old Iowa manufacturer — the highest flow rating in this catalog at this horsepower, traded off against a comparatively low 243 ft max head.
Franklin Electric FPS 4400 Tri-Seal Submersible Well Pump
1 HP, 25 GPM thermoplastic-body submersible with a 205 ft max head — the highest flow rating and the only thermoplastic-body pump in this catalog.
Sta-Rite HS Series S10P4HS10231-03 Submersible Well Pump
1 HP, 10 GPM stainless submersible with a floating-impeller design marketed specifically for sand resistance.
Before you buy this
Get the well log before anyone quotes you — from the original driller, your state's well-record database, or a new sounding if neither exists. Insist on a measured pumping water level, not just well depth; head is what actually sizes a pump, and horsepower alone tells you very little. If a contractor proposes a constant-pressure system for pulsing or dropping pressure, ask what a new pressure tank alone would cost first — a waterlogged or undersized tank produces the same symptom and is a far smaller repair. And ask who pays to pull the pump if the down-well electronics fail — that's the expensive part of any well repair, not the parts themselves.
