All five current-catalog models are listed as recoil start in Franklin’s published ordering information. Weight and low-oil shutoff values are model-specific. Confirm engine configuration and availability before ordering.
Older FBSGF and FBSDF Catalog References
The older Kendisco product page also includes the two models below. They are retained for identifying existing equipment and compatible replacement parts, but they do not appear in Franklin Electric’s currently displayed five-model FBSGF ordering list. Contact Ken’s Distributing to confirm whether a new unit or replacement part can still be ordered.
| Older Order No. | Model | Engine Reference | Engine CC | Suction x Discharge | Older Listed Weight |
|---|---|---|---|---|---|
| 90271012 | FBSGF-12 | Briggs & Stratton INTEK | 305 | 3 in. x 3 in. | 110 lb |
| 90273010 | FBSDF-10RF | Kohler diesel | 349 | 2 in. x 2 in. | 152 lb |
The earlier ordering sheet contains inconsistent engine/fuel-tank and low-oil-shutoff entries for some historical models. Check the actual engine plate and current manufacturer parts records before specifying or replacing these units.
How to Choose an FBSGF Pump
FBSGF-8 / FBSGF-8H: Smaller 2-inch gas-engine units with 127 cc Briggs & Stratton or 118 cc Honda engines. They suit applications whose required flow and head fall on the relevant performance curve.
FBSGF-10 / FBSGF-10H: 2-inch units with 205 cc Briggs & Stratton INTEK or 160 cc Honda engines. Use model-specific flow-at-head information rather than engine displacement alone to select the pump.
FBSGF-12H: The larger 270 cc Honda-powered configuration with 3-inch suction and 3-inch discharge connections, designed for higher-volume water transfer. Check hose sizing and required head before selection.
Typical Applications
- Temporary and agricultural irrigation: Water supply from tanks and approved open-water sources to temporary field or landscape irrigation systems.
- Construction water transfer: Portable pumping where on-site electrical power is unavailable.
- Commercial and municipal maintenance: Temporary water movement and support pumping under suitable operating conditions.
- Light industrial service: Transfer of compatible liquids within the pump’s pressure, temperature and material limits.
Although a semi-open impeller can be less susceptible to certain small particles than an enclosed design, the FBSGF is not assigned a guaranteed solids-size rating in the referenced series specification. Do not assume compatibility with abrasive slurry, chemicals or large debris without consulting the manufacturer.
FBSGF Performance: Flow Rate at Total Head
The following U.S. GPM values are from the published Franklin Electric FBSGF performance table. The original Kendisco page labels the largest-model row FBSGF-12; the current manufacturer catalog identifies the corresponding 270 cc Honda model as FBSGF-12H.
| Model | 30 ft | 40 ft | 50 ft | 60 ft | 70 ft | 80 ft | 90 ft | 100 ft |
|---|---|---|---|---|---|---|---|---|
| FBSGF-8 | 135 | 120 | 105 | 85 | 65 | 37 | — | — |
| FBSGF-10 | 170 | 165 | 155 | 140 | 118 | 95 | 65 | 30 |
| FBSGF-12H | 310 | 285 | 255 | 220 | 175 | 120 | 60 | — |
All table values are flow in US GPM at the total head shown. — indicates no published value at that operating point. Franklin’s series summary quotes capacity up to 298 GPM, while the published FBSGF-12H performance table states 310 GPM at 30 ft of head. Because those two manufacturer figures differ, use the latest model curve or ask for confirmation when sizing the pump.

Installation and Operation Considerations
- Initial priming: Fill the pump housing using the priming opening before first startup. Self-priming capability does not mean the pump can safely operate dry.
- Suction plumbing: Make the suction line airtight, support connections properly, and account for suction-lift limits in the model’s installation manual.
- Drive and setup: Mount the complete pump horizontally on a stable surface with safe engine ventilation. Confirm engine fuel, start and low-oil protection details for the selected model.
- Liquid compatibility: Check temperature, chemistry and solids content against cast iron, seal materials and the manufacturer guidance.
- Cold-weather storage: Drain the volute using the designated drain port before freezing conditions.
- Service: Refer to the correct pump and engine manuals before maintenance and allow hot components to cool.
