Overview
The FBSEF is the larger, totally-enclosed member of Franklin Electric’s self-priming family: a rugged cast iron volute with a large chamber for rapid priming, and a semi-open cast iron impeller for fertilizer, salt water, dirty water and other liquids. It covers capacities to 295 GPM and heads to 92 ft. For smaller duties with an ODP motor, see the FBSE.
- Cast iron volute with a large chamber for rapid self-priming
- Semi-open cast iron impeller, blind-hole tapped so liquid will not corrode the shaft
- Carbon/ceramic seal faces, FKM elastomers, 300-series stainless steel
- Totally-enclosed, fan-cooled (TEFC) motor
- NPT pipe connections

Digitized from the published curve in Franklin Electric Mi4073, p. 5 (vector data), and rounded down; feet of head = PSI × 2.31. The shut-off column is read at the start of each curve (1.5-2 GPM). Curves end at 78, 125, 140, 250 and 294 GPM, matching Franklin’s printed “capacities to 295 gpm, heads to 92 feet”. — = not published by Franklin Electric for that combination.
