Franklin Electric FAOT Series Frame Mount Centrifugal Pumps

Franklin Electric FAOT Frame Mount Centrifugal Pumps

The Franklin Electric FAOT Series comprises frame-mount, end-suction centrifugal pumps for water circulation, booster service, liquid transfer, spraying systems and general-service applications. The series includes FAOT-4, FAOT-5 and FAOT-6, with threaded pipe connections, a cast iron volute, mechanical shaft sealing and a bearing frame designed for belt or direct drive.

Franklin Electric publishes series performance of up to 120 GPM and up to 85 ft of head. Actual duty-point flow and head depend on the selected pump model, speed and system conditions. These are bare-shaft frame-mount pumps, not close-coupled motor-and-pump assemblies. Review the model and performance curve before requesting a quotation.

FAOT Series Features and Benefits

• Cast iron, rotatable volute: Helps accommodate piping layouts and includes tapped openings for venting and draining.
• Impeller for general-service water handling: Franklin Electric’s series literature describes an open-face cast iron design for solids handling. Confirm the precise impeller construction of the selected item before specifying solids-handling duty, because individual manufacturer listings differ.
• Mechanical shaft seal: Series literature specifies carbon/ceramic faces, BUNA (nitrile) elastomers and 300-series stainless steel components.
• Frame-mounted bearing assembly: Permits belt drive or direct drive using an appropriately selected motor or engine and drive arrangement.
• Mounting flexibility: Manufacturer literature permits vertical or horizontal mounting, subject to the installation manual and the selected drive configuration.
• Serviceable construction: Parts references are available for volutes, impellers, bearing assemblies, seals, gaskets and related hardware.

FAOT Series Technical Specifications

Series maximum values are not a single operating point. Select the required pump using the performance curve, operating speed and actual system head.

FAOT-4, FAOT-5 and FAOT-6 Model and Ordering Information

The three FAOT models have different connection sizes and performance curves. Use the item number to identify the exact model and confirm the drive requirements when requesting a quote.

FAOT-5 connection verification: Franklin Electric’s series data sheet lists a 1¼-inch discharge and 1½-inch suction, while a manufacturer product listing and Kendisco’s earlier table show a 1¼-inch suction. Confirm the physical connection size against the current model drawing or manufacturer before purchasing pipe fittings.

FAOT Pump Selection and Applications

FAOT pumps are listed by Franklin Electric for water circulation, booster service, liquid transfer, spraying systems, jockey pump service and general-purpose pumping. Choose by required flow, total dynamic head, available drive speed, suction conditions, pumped liquid and materials compatibility.

• Water circulation and transfer: Movement of compatible water and process liquids through general-service systems.
• Booster service: Pumping where system design requires additional head and the selected model meets the duty point.
• Spraying applications: Water or compatible spraying liquids, subject to seal/material suitability and the required pressure and flow.
• Commercial and agricultural systems: Installations needing a separately driven pump and flexible piping arrangement.

Although the FAOT family is described as suitable for solids handling in the series brochure, do not assume a particular solids passage size, slurry rating or chemical compatibility without product-specific confirmation. A jockey-pump application listing is not a fire-system approval or certification.

Installation and Drive Selection Considerations

• Drive selection: Match motor or engine power, pump speed, coupling or pulley configuration to the chosen operating point. The frame-mounted pump does not include an integral electric motor.
• Rotation: Confirm clockwise direction while facing the shaft, as identified in Franklin Electric’s product information.
• Initial filling: The FAOT is not identified as self-priming. Prime and vent the pump as directed in the official installation manual before startup.
• Piping: Select suction and discharge piping from the confirmed dimensions for the exact model. Ensure adequate suction conditions and avoid piping strain on the volute.
• Seal protection: Avoid dry running and verify temperature and chemical compatibility with the application.
• Service planning: Confirm the pump model, serial or production revision and parts diagram when ordering replacement components.

FAOT Exploded View and Replacement Parts

The following manufacturer-style parts reference, retained from the existing Kendisco product page, covers FAOT-4, FAOT-5 and FAOT-6. Identify replacement parts by pump model and production revision. Historical part-number listings should be confirmed before ordering, especially impellers and seals.

Note: This parts table is preserved for lookup continuity. It should not be treated as confirmation that each listed part remains available or is interchangeable across serial-number revisions.

FAOT Dimensions

Use the drawing and the dimensions below when evaluating installation space and fit. Dimensions are in inches unless otherwise identified. Confirm final dimensions and connection sizes for the selected model before fabrication or purchase.

Dimension letters A through N correspond to the drawing above. The original numerical dimensions have been retained; the FAOT-5 suction size remains subject to manufacturer confirmation.

FAOT Performance Curve

The performance curve helps distinguish the flow and head capabilities of FAOT-4, FAOT-5 and FAOT-6. Verify that the chosen pump can provide the intended flow at the calculated total dynamic head and planned shaft speed.

FAOT vs. FACT Frame Mount Centrifugal Pumps

The FAOT and FACT are distinct Franklin Electric frame-mount centrifugal pump families. The FAOT series is described by the manufacturer with an open-face impeller design, while the FACT series is associated with a different impeller and performance range. Compare the actual head-capacity curves, liquid characteristics, drive arrangement and model specifications instead of assuming the pumps can replace one another directly.

Frequently Asked Questions About the FAOT Series

What is the Franklin Electric FAOT Series used for?

Franklin Electric lists water circulation, booster service, liquid transfer, spraying systems, jockey pump service and general service among the FAOT applications. Final model selection depends on the required operating point and liquid characteristics.

Is the FAOT pump close-coupled?

No. The FAOT is a frame-mount centrifugal pump with a bearing frame intended for belt or direct drive. It should not be labeled as a close-coupled motor-pump assembly.

Which FAOT models are available?

The series is listed with three models: FAOT-4 (90251004), FAOT-5 (90251005) and FAOT-6 (90251006). Contact Ken’s Distributing to confirm current availability and the appropriate configuration for your application.

Is the FAOT a self-priming pump?

The FAOT is a conventional frame-mount centrifugal pump and is not described as self-priming in the manufacturer series information. Follow the official priming and installation instructions before startup.

What is the FAOT pump’s maximum flow and head?

Franklin Electric’s series data specifies up to 120 GPM and 85 ft of head. These are series limits, not guaranteed values at the same operating point. Review each model’s performance curve for your required system conditions.

Does every FAOT model use an open-face impeller?

Franklin Electric describes an open-face impeller in its FAOT series literature, but individual manufacturer listings contain differing impeller descriptions. Confirm the specific model and impeller before selecting the pump for a solids-handling application.

Are replacement parts available for FAOT-4, FAOT-5 and FAOT-6?

Part-number references for these models are included in the repair-parts table. Supply the pump model and production information so the correct replacement component and its availability can be confirmed.
