19 GPM, 1.5 HP, STAINLESS STEEL PUMP END

FranklinWater 4F 19 GPM 1.5 HP Stainless Steel 4″ Submersible Pump End — high-flow residential well pump end for higher-yield applications.
OverviewThe FranklinWater 4F 19 GPM 1.5 HP pump end is the highest-flow 4″ pump end in the 4F series, designed for residential wells with higher aquifer yield where 19 GPM is needed to serve homes with irrigation systems or high simultaneous demand. The 1.5 HP motor specification balances the increased flow rate with adequate head for wells of moderate to significant depth.304 stainless steel body and Noryl impellers. 1¼″ FNPT discharge. The larger 19 GPM hydraulic section requires a 1.5 HP motor for adequate performance; do not under-motor this pump end. At 19 GPM, column pipe should be upsized from 1¼″ to 1½″ for longer drops to reduce friction loss — verify with Franklin system sizing tables.
