FAF Series Axial Flow Vertical Turbine

Technical Product Description:

The Franklin Electric FAF Series Axial Flow Vertical Turbine is a vertical lineshaft turbine pump engineered for very high flow, low head water movement in demanding commercial, municipal, and industrial applications. Franklin Electric states that the FAF Series is used where water supply is readily available from rivers, lakes, ponds, streams, or water wells, making it well suited for installations that require moving large volumes of water efficiently.  

Franklin specifies that the FAF Series uses an axial-flow propeller design constructed of bronze, paired with a heavy wall bowl assembly that is vitreous enamel lined up to 15 inches. According to Franklin, this design provides a very broad operating range with very high efficiency, helping the pump perform effectively in high-flow applications.  

Franklin’s vertical lineshaft turbine brochure indicates that the FAF Series is available in 8-inch through 30-inch bowl sizes, with flows up to 40,000 GPM, heads up to 35 feet, liquid temperatures up to 200°F, and speed ranges from 1,800 RPM down to 450 RPM. These published values confirm the FAF Series is positioned for the highest-flow applications within Franklin’s vertical lineshaft turbine offering.  

Franklin also notes in its agricultural irrigation guidance that FAF Series axial flow pumps are intended for shallow depth sets up to 35 feet, distinguishing them from mixed flow alternatives intended for deeper settings. With its axial-flow hydraulic design, very high capacity, and low-head operating profile, the FAF Series is a strong option for applications such as irrigation water transfer, surface water movement, and other large-volume pumping systems. The final application framing is an inference based on Franklin’s published use cases and performance ranges.
