What Is the Franklin Electric 14 Inch Frame Mount Centrifugal Pump?
The Franklin Electric 14 inch frame mount centrifugal pump is identified by its 14 inch impeller diameter and represents the top of the Franklin Electric large-frame centrifugal pump series. It features a ductile iron volute with back pull-out design, an enclosed ductile iron impeller with external balance lines that reduce bearing load at the extremely high flow rates this pump operates at, and a heavy-duty iron bearing frame with oversized shaft and max-life bearings designed for continuous high-duty-cycle service.
The external balance lines on the 14 inch impeller are a design feature not found on smaller models in the series. At 7,000 GPM, the axial thrust forces acting on the impeller are significantly higher than on smaller pumps. The external balance lines redirect a controlled amount of pressurized fluid to equalize pressure across the impeller faces, reducing the net axial load on the thrust bearing and extending bearing service life in high-duty-cycle installations. The seal options include a packed-box with lantern ring or a mechanical seal using silicon carbide faces, FKM elastomers, and 18-8 stainless steel components.

Applications and Industries
The Franklin Electric 14 inch frame mount centrifugal pump is built for applications where maximum flow volume is the primary requirement. At 7,000 GPM, it delivers more than twice the maximum flow of the 13 inch model and is designed specifically for large pump station installations that serve irrigation districts, municipal treatment facilities, and high-volume industrial operations.
- Large irrigation district pump stations and flood irrigation distribution systems
- Municipal water supply intake, treatment plant operations, and distribution networks
- Major construction project dewatering and water management
- High-volume commercial water supply and storage filling operations
- Mining water management at scale including pit dewatering and process water supply
- Industrial processing, cooling water circulation, and high-volume water transfer
How the 14 Inch Model Compares to Other Franklin Electric Frame Mount Pumps
The 14 inch model is the top of the Franklin Electric inch-size frame mount centrifugal series at Ken’s Distributing. The comparison below shows how the 14 inch compares to the other models in the series across key performance metrics. If your flow requirement falls below 7,000 GPM, a smaller model may be a more cost-effective choice. Contact Kendisco for detailed performance curves and system sizing support.

Frequently Asked Questions
What is the Franklin Electric 14 inch frame mount centrifugal pump used for?
The Franklin Electric 14 inch frame mount centrifugal pump is used for maximum-volume agricultural irrigation district pump stations, municipal water supply intake and distribution, large-scale construction dewatering, mining pit dewatering, industrial processing water supply, and high-volume commercial water transfer. At 7,000 GPM, it is the highest-capacity surface pump in the Franklin Electric inch-size frame mount series available at Ken’s Distributing.
What does the 14 inch measurement refer to on this pump?
The 14 inch designation refers to the impeller and housing diameter of this pump model. Franklin Electric uses impeller diameter as the primary size identifier across its large-frame centrifugal pump series. The 14 inch is the largest model in the series and delivers 7,000 GPM, which is 2.5 times the 2,800 GPM maximum of the 13 inch model.
What are the external balance lines on the 14 inch impeller?
External balance lines are small passages or channels built into the pump that redirect a controlled amount of pressurized fluid from the high-pressure discharge side of the impeller to the low-pressure back side. This equalizes the pressure across both faces of the impeller, reducing the net axial thrust load on the thrust bearing. On a pump operating at 7,000 GPM, this bearing load reduction is critical for achieving acceptable bearing service life in continuous duty applications.
What seal options are available on the 14 inch frame mount pump?
The Franklin Electric 14 inch frame mount centrifugal pump is available with either a packed-box seal with lantern ring or a mechanical seal using silicon carbide faces, FKM elastomers, and 18-8 stainless steel components. The packed-box seal is a traditional field-serviceable option. The silicon carbide mechanical seal provides lower-maintenance, cleaner operation and is compatible with a wider range of fluid conditions.
Can this pump be serviced without disconnecting the piping?
Yes. The Franklin Electric 14 inch frame mount centrifugal pump uses a back pull-out design with casing jack-out holes that allow the rotating assembly to be removed for inspection and service without disconnecting the suction or discharge flanges. This significantly reduces downtime during maintenance on permanent large pump station installations.
What pipe connection type does the 14 inch frame mount pump use?
The Franklin Electric 14 inch frame mount centrifugal pump uses Class 150 flanged pipe connections across all five port size configurations from 3×5 inch through 10×10 inch. Class 150 flanged connections are the standard for large-diameter, high-pressure pump installations and are compatible with Class 150 flanged pipe fittings, valves, and reducers used in commercial, municipal, and industrial piping systems.
How does the 14 inch model differ from the 13 inch model?
The 14 inch model delivers 7,000 GPM at heads up to 375 feet compared to 2,800 GPM and 360 feet for the 13 inch model. The 14 inch uses a ductile iron impeller with external balance lines, while the 13 inch uses a 316 stainless steel impeller with internal hydraulic balancing. The 14 inch also offers a wider range of port sizes including a 10×10 inch configuration not available on the 13 inch. Contact Ken’s Distributing for detailed performance curve comparison between the two models.
