FVT Series Vertical Lineshaft Turbine

Technical Product Description:

The Franklin Electric FVT Series Vertical Lineshaft Turbine is a vertical lineshaft turbine pump designed for demanding commercial, municipal, and industrial water movement applications. Franklin Electric states that this series is ideal where water supply is readily available from rivers, lakes, ponds, streams, or water wells, making it suitable for a broad range of water transfer and supply duties.  

Franklin specifies that the FVT Series is built with ASTM A48 high tensile cast iron bowls, investment-cast 316 stainless steel impellers, and bronze bearings as standard. According to Franklin, these materials are intended to provide proven durability together with a highly efficient broad operating range.  

Franklin’s published materials also indicate that the FVT Series covers a very wide performance envelope. The company notes that its vertical lineshaft turbine offering includes deep-set systems delivering up to 2,500 feet of head, and its 2024 irrigation guidance says FVT Series pumps can be installed from about 10 feet to 2,500+ feet below grade and move up to 42,000 gallons per minute. Franklin’s 2020 launch materials also describe the FVT range as spanning 5-inch to 42-inch sizes.  

Franklin also notes that the FVT line comes in a variety of configurations, including mixed flow or axial flow options within the broader vertical lineshaft offering, depending on the application requirement. With its deep-set capability, high-head profile, and broad size range, the FVT Series is a strong option for high-demand water transfer, irrigation supply, municipal pumping, and other large-scale water system applications. The last sentence is an inference based on Franklin’s stated applications and published performance ranges.
