Franklin Electric Surface Water Pumps Centrifugal Frame Mount 9 Inch
Franklin Electric 9 inch frame mount centrifugal pump is a large-capacity, heavy-duty surface pump engineered for high-volume water transfer in agricultural irrigation, municipal water supply, construction dewatering, mining, and water truck applications. Available at Ken’s Distributing Company (Kendisco), the 9 inch model steps up significantly from the 7.5 inch model in the Franklin Electric inch-size frame mount series, delivering capacities up to 2,000 GPM and heads up to 260 feet for demanding large-scale operations.
Ken’s Distributing carries the Franklin Electric 9 inch frame mount centrifugal pump in both NPT and flanged connection configurations, along with genuine replacement parts for the XS3x4-9 and XS6x8-9 model variants. Whether you are building a new pump station or sourcing parts for an existing installation, the team at Kendisco is ready to help you get the right configuration for your application.
What Is the Franklin Electric 9 Inch Frame Mount Centrifugal Pump?
The Franklin Electric 9 inch frame mount centrifugal pump is identified by its 9 inch impeller diameter and is part of the Franklin Electric large-frame centrifugal series that ranges from the 7.5 inch through the 14 inch models. The 9 inch model delivers the highest flow rate of the commonly stocked models at Ken’s Distributing, with a maximum capacity of 2,000 GPM at heads up to 260 feet and a maximum working pressure of 250 PSI.
The pump features a heavy-duty cast iron volute with back pull-out design, an enclosed double-keyed cast iron impeller for improved reliability and high efficiency, and a heavy-duty iron bearing frame with oversized shaft and max-life bearings. The double-keyed impeller connection is a notable upgrade over single-key designs, providing better torque transfer and reducing the risk of impeller slippage under high-load conditions. Both packed-box and mechanical seal options are available to match your fluid conditions and maintenance preferences.

- Commercial water supply and distribution
- Construction site dewatering on large-scale projects
- Municipal water supply and treatment plant operations
- Mining water management and process water handling
- Light industrial high-volume water transfer
- Water truck filling for dust control, agriculture, and firefighting support
XS3x4-9 vs. XS6x8-9: Choosing the Right Configuration
The Franklin Electric 9 inch frame mount centrifugal pump is available in two model variants at Ken’s Distributing. The XS3x4-9 uses a 3 inch discharge and 4 inch suction with NPT threaded connections and is available in both clockwise and counterclockwise rotation to match your drive and piping layout. The XS6x8-9 uses a 6 inch discharge and 8 inch suction with Class 150 flanged connections and is configured for the highest-volume applications in the series. If you are not sure which model fits your system, contact Kendisco for help reviewing your flow and pressure requirements.
Comparing the Franklin Electric Inch-Size Frame Mount Series
The 9 inch model delivers significantly higher flow than the 7.5 inch model in the Franklin Electric frame mount centrifugal series. Ken’s Distributing also carries the 10 inch, 13 inch, and 14 inch models for applications that require even greater capacity. If you need help comparing performance curves across the full inch-size range, the team at Kendisco can help you match the right model to your system design requirements.

Frequently Asked Questions
What is the Franklin Electric 9 inch frame mount centrifugal pump used for?
The Franklin Electric 9 inch frame mount centrifugal pump is used for large-scale agricultural irrigation, municipal water supply, construction dewatering, commercial water transfer, mining water management, and water truck filling. Its 2,000 GPM capacity and 260-foot head rating make it one of the highest-output models in the Franklin Electric surface pump lineup available at Ken’s Distributing.
What does the 9 inch measurement refer to on this pump?
The 9 inch designation refers to the impeller and housing diameter of this pump model. Franklin Electric uses the impeller diameter as the primary size identifier across its large-frame centrifugal pump series. Larger impeller diameters correspond to higher flow rates and head ratings. The 9 inch model delivers approximately twice the flow capacity of the 7.5 inch model in the same series.
What is the difference between the XS3x4-9 and XS6x8-9 models?
The XS3x4-9 uses a 3 inch discharge and 4 inch suction with NPT threaded connections and is available in clockwise or counterclockwise rotation. The XS6x8-9 uses a 6 inch discharge and 8 inch suction with Class 150 flanged connections for the highest-volume applications in the 9 inch series. Contact Ken’s Distributing for help selecting the right model for your system flow and connection requirements.
Why does the 9 inch model use a double-keyed impeller?
The double-keyed impeller connection on the Franklin Electric 9 inch frame mount centrifugal pump provides better torque transfer between the shaft and impeller compared to a single-key design. At the high flow rates and power levels this pump operates at, a double-keyed connection reduces the risk of impeller slippage or damage under load, improving reliability over the long term.
Can the 9 inch frame mount pump be serviced without disconnecting the piping?
Yes. The Franklin Electric 9 inch frame mount centrifugal pump uses a back pull-out design that allows the rotating assembly to be removed for inspection and service without disconnecting the suction or discharge piping. This is a practical advantage in permanent pump station installations where downtime needs to be minimized.
What replacement parts are available for the Franklin Electric 9 inch frame mount pump?
Ken’s Distributing Company (Kendisco) carries genuine Franklin Electric replacement parts for the 9 inch frame mount centrifugal pump including volute cases in NPT clockwise, NPT counterclockwise, and flanged configurations.
