Franklin Electric AG Series Close-Coupled Centrifugal Pump

What Is the Franklin Electric AG Series Close Coupled Centrifugal Pump?

The Franklin Electric AG Series Close Coupled Centrifugal Pump is a high-flow, heavy-duty centrifugal pump designed for agricultural irrigation, commercial water supply, municipal infrastructure, and industrial pumping applications. Available at Ken’s Distributing, the AG Series produces flow rates ranging from 65 to 900 gallons per minute, making it one of the most capable and widely used close coupled centrifugal pump families in the entire Franklin Electric product line.

What makes the Franklin Electric AG Series Close Coupled Centrifugal Pump especially popular among contractors, engineers, and agricultural operators is its combination of industrial-grade construction and practical serviceability. The all-iron construction, CA6NM stainless steel impellers, back pullout design, and replaceable 416 stainless steel shaft sleeves mean this pump is built to handle demanding, continuous-duty applications while remaining straightforward to maintain and repair in the field.

Kendisco carries the Franklin Electric AG Series in multiple HP, phase, and motor enclosure configurations. As part of a 9-pump family covering the most popular hydraulic performance ranges, the AG Series offers exceptional flexibility for matching the right pump to your specific flow rate, pressure, and system requirements. Whether you are setting up a large-scale irrigation system, a municipal water distribution network, or a commercial pressure boosting installation, the AG Series has a configuration that fits.

What Does AG Stand For and Why Is It the Go-To Pump for Agricultural and Commercial Use?

The AG designation stands for Agricultural, reflecting the series’ roots as a pump designed for high-volume water transfer in farming and irrigation applications. However, over the years the Franklin Electric AG Series Close Coupled Centrifugal Pump has proven itself in a far wider range of demanding applications beyond agriculture, including municipal water systems, industrial wash-down operations, and commercial pressure boosting systems.

Here is why the AG Series has become a top choice across these diverse applications:

• Massive Flow Range: With flow rates from 65 to 900 GPM across the 9-pump family, the AG Series covers an exceptionally wide range of hydraulic requirements from a single pump platform.
• 9-Pump Family: The AG Series is not a single pump model. It is a family of 9 pump configurations covering the most popular hydraulic performance curves, so you can select the exact combination of flow rate and head pressure that matches your system needs.
• CA6NM Stainless Steel Impellers: CA6NM is a high-strength martensitic stainless steel alloy that provides superior corrosion resistance and mechanical durability compared to standard cast iron impellers. This is a critical advantage in agricultural environments where water quality varies.
• All-Iron Construction: The ASTM-A48 CL30 cast iron volute provides heavy-duty strength and durability for demanding, long-running installations.
• Both 1800 and 3600 RPM Motor Options: Unlike many close coupled centrifugal pump series that are limited to a single motor speed, the AG Series supports both 1800 and 3600 RPM NEMA standard JM and JP frame motors, giving you more flexibility to match motor speed to your application requirements.

If you need a pump that can handle high-volume water transfer in tough agricultural, commercial, or industrial environments, the Franklin Electric AG Series is a proven and reliable solution. The team at Ken’s Distributing can help you identify the right AG Series model for your specific flow rate, head pressure, and installation requirements.

Key Features and Benefits of the Franklin Electric AG Series Close Coupled Centrifugal Pump

• Part of a 9-Pump Family: The AG Series covers the most popular hydraulic performance ranges, supporting flow rates from 50 to 900 GPM across the full family. This gives engineers and installers the flexibility to select the exact hydraulic match for their application.
• All-Iron Construction with ASTM-A48 CL30 Cast Iron Volute: The durable cast iron volute provides long-term strength and reliability in demanding environments. ASTM-A48 CL30 is a high-quality gray cast iron standard commonly specified in commercial and industrial pump applications.
• CA6NM Stainless Steel Enclosed Impellers: The high-performance enclosed impellers are made from CA6NM stainless steel for superior corrosion resistance, erosion resistance, and consistent water delivery over the service life of the pump.
• 416 Stainless Steel Shaft Sleeves: Replaceable shaft sleeves made from 416 stainless steel protect the pump shaft from wear and corrosion. When wear occurs, the sleeve can be replaced without replacing the entire shaft, reducing maintenance costs significantly.
• Back Pullout Design: The rotating element of the pump, including the impeller, shaft, seal, and bearings, can be pulled out from the back of the casing for service and maintenance without disconnecting the suction or discharge piping.
• Flexible Seal Options: Available with standard carbon, ceramic, nitrile, and 316 stainless steel mechanical seals, or a packing box option for applications where controlled leakage is acceptable.
• Flexible Connection Options: Available with threaded NPT connections or 125 pound flanged connections, allowing integration with different piping systems and installation standards.
• NEMA Standard JM and JP Frame Motors: Available in both 1800 RPM and 3600 RPM configurations, with NEMA standard JM and JP shaft designs for broad motor compatibility and easy motor replacement.
• ODP and TEFC Motor Enclosures: Choose between Open Drip Proof enclosures for clean, dry indoor environments, or Totally Enclosed Fan Cooled enclosures for outdoor, dusty, or humid installations.
• Vertical or Horizontal Mounting: Can be installed in either vertical or horizontal orientation to accommodate different system layouts and available installation space.
• Designed for Increased Pumping Efficiency: The hydraulic design of the AG Series is optimized for high efficiency across the full range of flow and head conditions, reducing energy costs in continuous-duty applications.
