Franklin Electric FBSEF Series Self-Priming Pumps, 1.5–7.5 HP

FBSEF Pump Manuals & Repair Resources

FBSEF Series Overview

The Franklin Electric FBSEF Series is a cast iron, close-coupled self-priming centrifugal pump family with motor choices from 1.5 to 7.5 HP. Designed for water transfer and compatible liquids in irrigation, construction, municipal, commercial, mining and light-industrial settings, the series offers capacities up to 295 GPM and heads up to 92 feet, depending on the selected model and operating conditions.

FBSEF pumps pair a cast iron volute and large priming chamber with a semi-open cast iron impeller. The self-priming arrangement is intended to simplify restarting after the pump has been initially filled and adequate priming liquid remains in the casing. The close-coupled design integrates the pump and motor into a compact assembly.

This listing also includes model and service information for the related FBSEFL low-speed series (0.5 to 1 HP at 1800 RPM), plus complete-pump ordering numbers, pump-end kits, replacement motors, repair parts and dimensional references. Quote by exact model number and item number to ensure the correct horsepower, phase, voltage and motor frame.

FBSEF Pump Features and Benefits

• Self-priming cast iron volute: A large chamber is designed to support rapid priming and practical water-transfer operation.
• Semi-open cast iron impeller: Suitable for applications involving fertilizer solutions, salt water and dirty water where chemical compatibility and solids content are within the manufacturer’s limitations.
• Blind-hole tapped impeller: Helps protect the shaft from contact with pumped liquid.
• Close-coupled assembly: Compact pump-and-motor configuration without a separate field-aligned coupling.
• TEFC motors: Totally enclosed fan-cooled motor configurations are listed across the FBSEF and FBSEFL model range.
• Multiple electrical configurations: Single- and three-phase models, including selected 575V three-phase variants.
• Repair and replacement support: Identifiable pump-end kits, motor ordering numbers and 56J/JM-frame repair parts help buyers specify compatible components.

FBSEF Series Technical Specifications

Published maximum capacity and maximum head are series-level ratings, not simultaneous performance at one operating point. Select the exact pump from its performance curve at the required flow and total dynamic head. Liquid and material compatibility must be verified for the application.

FBSEF Model and Ordering Information

The tables below combine the model identification and item links from the overlapping product page with the motor frame and shipping-weight information from the existing detailed listing. Select the exact model for the site’s electrical supply and system duty point.

FBSEF 3600 RPM Single-Phase Pumps

FBSEF 3600 RPM Three-Phase Pumps

Voltage verification: Published Franklin Electric resources disagree on the FBSEF-200-SE (item 92932020) input-voltage rating. Confirm this model against the current manufacturer data sheet and motor nameplate before quoting or ordering.

FBSEFL 1800 RPM Low-Speed Models

The FBSEFL models are related low-speed alternatives, not 1.5–7.5 HP FBSEF models. They should be selected using their separate 1800 RPM performance curve. The FBSEFL-075-TE assembly is listed as a 0.75 HP pump model, and Franklin Electric’s catalog notes that it uses a 1 HP motor.

Applications and Selecting the Right FBSEF Pump

The FBSEF series is used for irrigation water movement, commercial and municipal water-transfer duties, construction applications and other compatible light-industrial services. The semi-open impeller is intended for certain challenging liquids, but the construction material, seal specification and actual liquid characteristics still govern suitability.

• Flow and head: Determine required GPM at the actual total dynamic head, rather than choosing by the maximum GPM or horsepower alone.
• Electrical service: Match the specific model’s phase, supply voltage, frequency and motor rating. Do not infer electrical ratings from other FBSEF models.
• Connection size: Check the suction and discharge NPT dimensions for the chosen model.
• Liquid compatibility: Confirm temperature, solids, corrosion potential and mechanical-seal suitability before specifying the pump.
• Replacement compatibility: For repairs or pump-end kits, check the existing model, motor frame, shaft configuration and manufacturing date.

FBSEF and FBSEFL Dimensions

Compare mounting and port measurements with the proposed installation or existing pump. All dimensional table values are in inches and are for estimating purposes only.

FBSEF and FBSEFL Pump-End Kits (Less Motor)

Pump-end kits provide a pump assembly without a motor. Match the kit part number, motor frame and shaft arrangement to the exact application. The FBSEFL low-speed configurations use pump-end kit identifiers also listed under the FBSEF family.

Replacement Motor Specifications and Item Numbers

The following manufacturer part and motor references were present in the original product documentation. Motor replacements require confirmation of horsepower, phase, speed, frame, electrical ratings and mounting compatibility. Verify current item availability and supersession before ordering.

FBSEFL-075-TE motor note: The manufacturer’s catalog specifies a 1 HP motor for this 0.75 HP pump model. Check replacement-motor suitability with the exact model and motor nameplate.

FBSEF and FBSEFL Performance Curves

Compare the intended operating point to the manufacturer curves before selecting a pump. The FBSEF and FBSEFL families run at different nominal speeds and require separate performance-curve review.

Installation and Service Considerations

• Priming: Fill the pump casing as required by the installation manual before initial startup. Self-priming does not mean the unit can safely run dry.
• Suction layout: Size and route the suction line to minimize air leaks and excessive friction loss. Follow the installation manual for valves and fittings.
• Motor protection: TEFC does not mean submersible. Provide appropriate electrical protection and install within the manufacturer’s environmental limits.
• Servicing: Identify the exact frame, model, part number and production date before selecting seals, impellers, motors or case components.
• Materials compatibility: Confirm the pumped liquid’s temperature, chemistry and solids against the installed materials and seal before use.

Frequently Asked Questions

What is a Franklin Electric FBSEF pump?

It is a close-coupled, cast iron, self-priming centrifugal pump in Franklin Electric’s FBSEF series. The series includes 1.5 to 7.5 HP models for water-transfer and other manufacturer-approved liquid applications.

What is the maximum flow of the FBSEF series?

The manufacturer’s published series capacity is up to 295 GPM. Actual flow depends on the exact model, total dynamic head and installation conditions.

How is FBSEFL different from FBSEF?

FBSEF is the 3600 RPM pump family with 1.5 to 7.5 HP models. FBSEFL includes lower-speed 1800 RPM models covering 0.5 to 1 HP, with different operating curves.

Are FBSEF pumps available in single-phase and three-phase configurations?

Yes. The model tables list both types. Available voltage and horsepower combinations depend on the specific model and item number; confirm the motor nameplate before ordering.

Does an FBSEF pump require initial priming?

Yes. Follow Franklin Electric’s priming and installation instructions before initial use. Avoid dry running and verify the pump retains the required priming liquid between operating cycles.

Can I obtain FBSEF mechanical seals, impellers or pump-end kits?

Replacement-part and pump-end-kit identifiers are listed on this page for the applicable 56J and JM frame models. Provide the exact pump model, part number and equipment date when requesting a quote.

What is the difference between the FBSE and FBSEF pump series?

The related Franklin Electric FBSE series covers lower horsepower configurations, while FBSEF extends the self-priming family to 7.5 HP and higher published series capacity. Select either pump using its actual performance curve, not horsepower alone.
