Franklin Electric Centrifugal Self Priming Gas Engine Units FMIG Water Pump
Franklin Electric Centrifugal Self Priming Gas Engine Units FMIG for High-Volume Irrigation and Industrial Water Transfer
Franklin Electric Centrifugal Self Priming Gas Engine Units FMIG are large-capacity self-priming centrifugal pump units powered by industry-recognized Honda and Kohler engines. Available through Ken’s Distributing Company at Kendisco, the FMIG series handles flow rates up to 400 GPM and heads up to 165 feet, with a maximum working pressure of 120 PSI, making it the highest-capacity gas engine self-priming pump in the Franklin Electric surface pump lineup.
The cast iron volute features a removable front cover with a built-in check valve that facilitates self-priming without manual intervention. The semi-open, two-vane cast iron impeller is capable of handling spherical solids, making the FMIG suitable for applications where the water source contains light debris or sediment. A replaceable steel wear plate maintains maximum pump efficiency over the life of the unit, reducing the cost of long-term maintenance.
The FMIG is available in three configurations: the FMIG30-13H with a Honda GX390 289cc engine through a 3 inch connection, and the FMIG40-18K and FMIG40-27K with Kohler CH620 and CH740 engines through 4 inch connections. All models include low oil shut-off and horizontal mounting. Ken’s Distributing Company at Kendisco stocks all three FMIG models along with genuine Franklin Electric repair parts, replacement impellers, and flapper valve assembly kits.

Frequently Asked Questions
What is the Franklin Electric Centrifugal Self Priming Gas Engine Units FMIG used for?
The Franklin Electric Centrifugal Self Priming Gas Engine Units FMIG are designed for high-volume water transfer in agricultural irrigation, construction dewatering, mining, municipal water supply, and industrial applications. With flow rates up to 400 GPM through 3 inch and 4 inch connections, the FMIG is the largest-capacity gas engine self-priming pump in the Franklin Electric lineup and is well suited for applications where the FBSGF or FNSGF do not provide enough flow. Ken’s Distributing Company at Kendisco stocks all three FMIG models for fast order fulfillment.
How does the FMIG differ from the FBSGF and FNSGF gas engine pumps?
The three Franklin Electric gas engine self-priming pumps serve different capacity ranges. The FBSGF handles up to 298 GPM through 2 inch and 3 inch connections using a semi-open impeller for dirty water. The FNSGF handles up to 165 GPM but achieves heads up to 185 feet using an enclosed impeller for high-pressure clean water applications. The FMIG is the highest-capacity option, handling up to 400 GPM through 3 inch and 4 inch connections using a semi-open two-vane impeller capable of handling spherical solids. Select the FMIG when your application requires maximum flow volume from a portable gas engine pump.
What engine options are available for the FMIG?
The FMIG is available with a Honda GX390U1 289cc OHV engine on the FMIG30-13H model, and with Kohler CH620 624cc and Kohler CH740 725cc engines on the FMIG40-18K and FMIG40-27K models respectively. All three models include low oil shut-off as standard. The Honda model uses a 6.9 quart fuel tank. Kohler-powered models are available through Kendisco and Ken’s Distributing Company.
What is the replaceable wear plate on the FMIG and how does it help?
The replaceable steel wear plate on the FMIG sits between the impeller and the pump case and maintains the tight clearance needed for efficient pumping. As the pump operates over time, this clearance gradually increases as the components wear, which reduces flow rate and efficiency. Rather than replacing the entire pump end, you can install a new wear plate to restore original performance. This is a particularly important feature on a high-capacity pump like the FMIG where replacement parts costs can be significant. Genuine FMIG wear plates are available through Kendisco by part number for each model.
What types of liquids can the FMIG handle?
The FMIG semi-open two-vane cast iron impeller is designed to handle water and liquids containing spherical solids. This makes the FMIG suitable for construction site dewatering where the water contains debris, agricultural field applications where the source water contains sediment, and general water transfer applications where the liquid is not entirely clean. It is not designed for highly corrosive chemicals or liquids incompatible with cast iron components.
Where can I find replacement parts for the FMIG at Kendisco?
Ken’s Distributing Company at Kendisco carries genuine Franklin Electric replacement parts for all three FMIG models, including pump cases, impellers by model number, motor adapters, mechanical shaft seals, wear plates, flapper valve assembly kits, suction flanges, and all hardware. Parts are listed by figure number with separate part numbers for the FMIG30-13H and the FMIG40-18K and FMIG40-27K models. Contact Kendisco directly to confirm part availability and compatibility before ordering.
What is the flapper valve assembly kit for the FMIG?
The flapper valve assembly kit includes all the components needed to rebuild the suction check valve assembly on the FMIG. For the FMIG30-13H, kit part number 305455021 includes the flapper valve, top and bottom check valve weights, flapper bolt, nut, and washer. For the FMIG40-18K and FMIG40-27K, kit part number 305455022 includes the same components excluding the washer. These kits are available through Kendisco and Ken’s Distributing Company for routine maintenance and field repairs.
