Franklin Electric Centrifugal Self priming FBSEF 1.5 – 7.5HP
Franklin Electric Centrifugal Self Priming FBSEF 1.5-7.5HP for Industrial Irrigation and Municipal Water Transfer
Franklin Electric Centrifugal Self Priming FBSEF 1.5-7.5HP is a high-capacity self-priming close-coupled centrifugal pump built for demanding irrigation, construction, mining, municipal, and industrial water transfer applications. Available through Ken’s Distributing Company at Kendisco, the FBSEF series handles flow rates up to 295 GPM and heads up to 92 feet, making it one of the most capable close-coupled self-priming pumps in the Franklin Electric lineup.
The rugged cast iron volute features a large priming chamber that allows the pump to self-prime quickly and reliably, even after extended idle periods. The semi-open cast iron impeller is designed to handle fertilizer solutions, salt water, dirty water, and other liquids that would damage or clog a standard closed impeller. The blind-hole tapped impeller design prevents liquid from reaching the shaft, protecting against internal corrosion and extending the service life of the pump.
All FBSEF models use a totally enclosed fan-cooled (TEFC) motor enclosure, which makes them suitable for outdoor and wet environments where motor protection is essential. The FBSEF series is available in 56J and JM frame configurations, covering single-phase and three-phase options from 1.5 HP through 7.5 HP. The FBSEFL variant runs at 1800 RPM and is available in 1/2 HP through 1 HP for lower-speed applications. Ken’s Distributing Company at Kendisco stocks the full FBSEF and FBSEFL lineup along with genuine Franklin Electric replacement parts and pump end kits.

Frequently Asked Questions
What is the Franklin Electric Centrifugal Self Priming FBSEF 1.5-7.5HP used for?
The Franklin Electric Centrifugal Self Priming FBSEF 1.5-7.5HP is designed for high-volume irrigation, construction dewatering, mining, municipal water transfer, and industrial liquid handling. Its large self-priming chamber and semi-open impeller make it particularly well suited for applications involving fertilizer solutions, salt water, dirty water, or other liquids that would damage a standard closed impeller pump.
What is the difference between the FBSEF and the FBSE series?
The FBSE series covers 1/2 HP through 3 HP at 3600 RPM and is designed for residential, light commercial, and light industrial applications. The FBSEF series starts at 1.5 HP and goes up to 7.5 HP at 3600 RPM, making it the better choice for larger irrigation systems, industrial operations, and municipal applications that require higher flow rates up to 295 GPM. If your application exceeds the 126 GPM capacity of the FBSE, the FBSEF is the right step up.
What is the FBSEFL variant and how does it differ from the FBSEF?
The FBSEFL is the low-speed variant of the FBSEF series, running at 1800 RPM instead of 3600 RPM. It is available in 1/2 HP through 1 HP in three-phase configurations, with the 1/2 HP model also available in single-phase. The lower RPM makes the FBSEFL suitable for applications where reduced speed and lower flow rates are preferred. Ken’s Distributing Company at Kendisco stocks both the FBSEF and FBSEFL variants.
What motor enclosure does the FBSEF series use?
All FBSEF and FBSEFL models use a totally enclosed fan-cooled (TEFC) motor enclosure. This makes them suitable for outdoor installations and wet environments where the motor needs protection from moisture, dust, and debris. The TEFC enclosure is one of the reasons the FBSEF is a popular choice for construction sites, agricultural fields, and municipal applications.
What voltage options are available for the FBSEF 1.5-7.5HP?
Single-phase FBSEF models are available in 115/230V (1.5 HP and 2 HP) and 230V only (3 HP and 5 HP). Three-phase models cover 230/460V across all horsepower ratings from 1.5 HP through 7.5 HP, with 575V options available for the 5 HP and 7.5 HP models. All configurations are available through Kendisco and Ken’s Distributing Company.
Are pump end kits available for the FBSEF series?
Yes. Pump end kits are available for all FBSEF models from 1.5 HP through 7.5 HP, as well as for the FBSEFL 1/2 HP through 1 HP variants. These kits allow you to mount the pump end to your own motor. The 1.5 HP through 3 HP models use 56J frame motors, while the 5 HP and 7.5 HP models use 184JM frame motors. All pump end kits are available by order number through Kendisco.
Where can I find genuine replacement parts for the FBSEF at Kendisco?
Ken’s Distributing Company at Kendisco carries genuine Franklin Electric replacement parts for the full FBSEF and FBSEFL series, including pump cases, impellers, motor adaptors, mechanical shaft seals, O-rings, water slingers, shaft sleeves, shaft keys, and all hardware. Parts are listed by figure number and part number for both the 56J frame and JM frame configurations, covering current and pre-May 2019 builds.
