Franklin Electric Centrifugal Frame Mount Self Prime FMIT Water Pump and Repair Parts
Franklin Electric FMIT frame mount self-priming pump is one of the highest-performing portable centrifugal pumps in the Franklin Electric surface pump lineup, and it holds the distinction of being among the top-clicked pages at Ken’s Distributing Company (Kendisco) for good reason. With capacities up to 760 GPM, heads up to 175 feet, and the ability to handle water containing mud, sand, and silt up to 10 percent by volume, the FMIT is built for serious work in irrigation, construction, mining, municipal, and water truck applications.
The FMIT is a frame mount design, meaning the pump end is mounted to a separate bearing frame and driven by a belt, direct drive, or engine rather than being coupled directly to a motor. This gives you flexibility in selecting your power source and makes the pump adaptable to a wide range of field configurations. Ken’s Distributing stocks the complete FMIT lineup along with all genuine Franklin Electric replacement parts and repair components.
What Is the Franklin Electric FMIT Frame Mount Self-Priming Pump?
The Franklin Electric FMIT frame mount self-priming pump is a heavy-duty centrifugal pump designed to self-prime on startup, meaning it does not require a foot valve or manual priming in most installations. The semi-open cast iron impeller handles solids up to 1-3/8 inches in diameter depending on the model size, making it capable of pumping water that contains debris, sediment, mud, and silt without clogging.
The pump features a rugged cast iron volute with tapped openings for priming, venting, and draining, a heavy-duty sealed bearing frame with a keyed stainless steel shaft, and a replaceable wear plate that allows you to restore pump efficiency without replacing the entire pump casing. The mechanical seal uses standard carbon and ceramic faces with FKM elastomers and 300 series stainless steel components for reliable, long-term sealing performance.

Frequently Asked Questions
What is the Franklin Electric FMIT frame mount self-priming pump used for?
The Franklin Electric FMIT frame mount self-priming pump is used for irrigation, construction dewatering, mining water transfer, commercial pumping, municipal water supply, light industrial applications, and water truck filling. Its semi-open impeller and self-priming design make it especially practical for pumping water from open sources like ponds, ditches, and flooded construction sites where debris content is variable.
What does self-priming mean on the FMIT pump?
A self-priming pump is designed to evacuate air from the suction line and prime itself on startup without requiring a foot valve or manual priming. The Franklin Electric FMIT self-primes through its volute design which retains enough water between uses to restart the priming cycle the next time the pump is started. This reduces setup time significantly on job sites and irrigation applications.
What size solids can the FMIT pump handle?
The FMIT handles solids up to 3/4 inch on the FMIT-20, up to 1 inch on the FMIT-30, and up to 1-3/8 inch on the FMIT-40. All models can handle water containing mud, sand, and silt up to 10 percent by volume without clogging.
What is the maximum flow rate of the Franklin Electric FMIT pump?
The Franklin Electric FMIT frame mount self-priming pump delivers capacities up to 760 GPM with heads up to 175 feet and a maximum working pressure of 120 PSI, making it one of the highest-output self-priming pumps in the Franklin Electric surface pump lineup.
What drive options are compatible with the FMIT pump?
The FMIT is a frame mount pump designed for bolt drive or direct drive configurations. The heavy-duty sealed bearing frame with keyed stainless steel shaft is compatible with belt drive, engine direct drive, and motor direct drive setups depending on your power source and installation requirements.
