Franklin Electric Centrifugal Self Priming Hydraulic Driven FMIH Water Pump
Franklin Electric Centrifugal Self Priming Hydraulic Driven FMIH for Agricultural, Municipal and Industrial Water Transfer
Franklin Electric Centrifugal Self Priming Hydraulic Driven FMIH is a high-capacity hydraulic-powered self-priming centrifugal pump built for demanding agricultural, municipal, construction, and industrial water transfer applications. Available through Ken’s Distributing Company at Kendisco, the FMIH handles flow rates up to 760 GPM and heads up to 145 feet, with a maximum working pressure of 120 PSI, making it one of the most capable hydraulic driven self-priming pumps in the Franklin Electric surface pump lineup.
The rugged cast iron volute features tapped openings for priming, venting, and draining, keeping installation and maintenance straightforward in the field. The semi-open, non-clogging cast iron impeller is designed primarily for water transfer but is also capable of handling mud, sand, and silt up to 10 percent by volume, which makes the FMIH a practical choice for construction dewatering, agricultural field work, and water truck applications where the liquid being pumped is not always clean.
The hydraulic drive bearing frame uses heavy sealed bearings and a keyed stainless steel shaft, with a B-Fit 7/8 inch hydraulic spline shaft for connection to a tractor or equipment hydraulic system. A replaceable wear plate is included to help maintain maximum pump efficiency over time without requiring a full pump end replacement. Ken’s Distributing Company at Kendisco stocks the FMIH-40 model along with genuine Franklin Electric repair parts for all major components.

Frequently Asked Questions
What is the Franklin Electric Centrifugal Self Priming Hydraulic Driven FMIH used for?
The Franklin Electric Centrifugal Self Priming Hydraulic Driven FMIH is designed for high-volume water transfer in agricultural irrigation, construction dewatering, mining, municipal water supply, and water truck operations. Its hydraulic drive design makes it ideal for remote field applications where electrical power is not available, connecting directly to a tractor or equipment hydraulic system through a B-Fit 7/8 inch spline shaft.
What does hydraulic driven mean on the FMIH pump?
Hydraulic driven means the FMIH pump is powered by the hydraulic system of a tractor or other equipment rather than by a separate electric motor or gas engine. The pump connects to the equipment hydraulic output through a B-Fit 7/8 inch spline shaft, allowing it to operate in remote agricultural fields, construction sites, and other locations where running electrical power or a gas engine is not practical or possible.
What types of liquids can the FMIH handle?
The FMIH semi-open, non-clogging impeller is designed primarily for water transfer but is also capable of handling mud, sand, and silt up to 10 percent by volume. This makes the FMIH suitable for construction site dewatering, agricultural field applications where the water source contains sediment, and water truck operations where the water being pumped may not always be clean.
What is the maximum flow rate and pressure for the FMIH?
The Franklin Electric FMIH delivers flow rates up to 760 GPM and heads up to 145 feet, with a maximum working pressure of 120 PSI. The 4 inch suction and 4 inch discharge connections support the high flow rates required in agricultural, municipal, and industrial applications. This performance range puts the FMIH well above the capacity of the close-coupled FBSE and FBSEF self-priming series.
What is the replaceable wear plate on the FMIH and why does it matter?
The replaceable wear plate sits between the impeller and the pump case and maintains the tight clearance needed for maximum pump efficiency. Over time, this clearance can widen as the components wear, reducing flow and efficiency. Rather than replacing the entire pump end, you can replace just the wear plate to restore the original performance specifications. Genuine FMIH wear plates are available through Kendisco and Ken’s Distributing Company under part number 305455009.
How does the FMIH compare to the FBSGF gas engine self-priming pump?
Both the FMIH and the FBSGF are self-priming centrifugal pumps designed for portable agricultural and field applications without electrical power. The key difference is the power source. The FMIH is driven by a tractor hydraulic system and offers significantly higher flow capacity at up to 760 GPM through a 4 inch connection. The FBSGF is powered by an onboard gas engine and is available in smaller configurations for applications where a tractor is not available or practical. If you have a tractor with hydraulic output available on site, the FMIH is typically the higher-performing choice.
Where can I find replacement parts for the FMIH at Kendisco?
Ken’s Distributing Company at Kendisco carries genuine Franklin Electric replacement parts for the FMIH-40, including the pump case, impeller, seal plate, mechanical shaft seal, wear plate, check valve, bearing assembly, coupling, transmission head, and all hardware.
