Franklin Electric FAC ½–2 HP Close-Coupled Pumps & Parts

Franklin Electric FAC ½–2 HP close-coupled pumps serve water circulation, booster systems, water transfer and general-purpose pumping. Choose from ten motor-driven pump configurations across ½, ¾, 1, 1½ and 2 HP. If you need to repair an installed FAC pump, the model-by-model replacement-parts table below identifies the impeller, mechanical seal, pump case, adapter, gasket and O-ring numbers to quote.

Ken’s Distributing Company supplies complete water pumps and replacement parts to customers throughout the United States and Canada. Send the FAC model, Franklin item number, or the part number from your existing pump to request price and availability.

Franklin Electric FAC ½–2 HP Quick Specifications

The small FAC range uses cast-iron volutes and enclosed cast-iron impellers with 56J C-face motors. Its 60 GPM capacity and 130-foot head are separate series limits; select a pump at your required operating flow and total dynamic head.

FAC-50, FAC-75, FAC-100, FAC-150 and FAC-200 Models

Select the correct horsepower, phase and voltage first, then check the discharge and suction connection sizes. These are complete pumps with motors, not motorless pump-end kits. The numbers in the first column are Franklin Electric catalog order numbers. The weights shown are catalog shipping weights.

How to Choose the Correct FAC Pump

• ½ HP, FAC-50: 1-inch discharge and 1¼-inch suction. Select FAC-50S for single-phase service or FAC-50T for three-phase service.
• ¾ HP, FAC-75, and 1 HP, FAC-100: 1¼-inch discharge and 1½-inch suction; each is offered in single- and three-phase configurations.
• 1½ HP, FAC-150, and 2 HP, FAC-200: 1½-inch discharge and 2-inch suction; use the larger sizes where the system needs additional flow or head.
• Electrical check: ½ through 1½ HP single-phase units are listed as 115/230 V. The 2 HP single-phase unit is 230 V. Listed three-phase units are 208–230/460 V.

For a replacement pump, send the existing nameplate model, voltage, phase, pipe sizes and required flow at total dynamic head. This helps identify the closest FAC configuration instead of selecting on horsepower alone.

FAC ½–2 HP Repair Parts, Impellers and Mechanical Seals

FAC replacement parts vary by hydraulic size and by the production configuration. For example, the five impellers each have separate OEM item numbers: 305453017 for FAC-50, 305453018 for FAC-75, 305453019 for FAC-100, 305453020 for FAC-150 and 305453021 for FAC-200. The brochure lists mechanical shaft seal 305463029 across this ½–2 HP family.

Use the exploded drawing to identify the reference number, then check the exact column for your pump model in the parts table. Individual parts can be quoted separately from complete pump assemblies.

Important for older FAC pumps: Franklin Electric notes that pumps built before March 2015 use a case gasket and washer/hex-bolt arrangement in place of the later O-ring arrangement. Send the pump nameplate and approximate manufacturing date when requesting gasket or O-ring parts. The listed seal and hydraulic parts are specific to the FAC ½–2 HP group; do not assume they interchange with FAC 3–5 HP models.

Which Replacement Part Should You Request?

• Impeller or pump case: match the exact FAC-50, FAC-75, FAC-100, FAC-150 or FAC-200 column, not just horsepower.
• Mechanical seal: request OEM part 305463029 and provide the FAC model and pump configuration for confirmation.
• Gasket or O-ring: provide your pump production details to distinguish older gasket-style assemblies from later O-ring versions.
• Motor adapter and fasteners: use the manufacturer figure reference and part number from the matrix rather than ordering by visual similarity.

For other pump families, see the Franklin Electric replacement parts overview. For FAC-specific diagrams, the original repair-parts resource button at the top of this description is the direct reference.

FAC ½–2 HP Applications and Installation

• Circulation and booster service: general water circulation, pressure boosting and utility pumping where the pump curve meets the operating requirements.
• Water transfer and spraying systems: installations requiring a cast-iron centrifugal pump and appropriately sized suction and discharge piping.
• Jockey and general-service applications: select the specific pump against the system duty point and installation requirements.
• Mounting: the FAC housing supports vertical or horizontal mounting, with a rotatable volute for pipe alignment.
• Priming: the FAC is not self-priming. Prime the casing and suction line before startup and follow the applicable installation instructions.
• Electrical selection: verify nameplate voltage and phase. ODP motor installations must be suitable for their environment.

FAC ½–2 HP Dimensions and Installation Clearances

Dimensions differ by horsepower and motor phase. Match the drawing’s lettered dimensions to the correct row before specifying a replacement or planning plumbing clearances. Dimensions below are in inches and intended for installation planning.

FAC ½–2 HP Performance Curve and Pump Selection

Use the performance curve to check whether a selected FAC pump can supply the required gallons per minute at your system’s total dynamic head. Head decreases as flow increases. The manufacturer’s 75 PSI maximum working-pressure limit is not the same as the pump’s delivered discharge pressure at every flow rate.

The ½–2 HP FAC family is separate from the larger FAC 3–5 HP pumps and repair parts, which have different motor arrangements, hydraulic components and replacement-parts listings.

Frequently Asked Questions About FAC Pumps and Parts

What FAC models are covered by this page?

FAC-50, FAC-75, FAC-100, FAC-150 and FAC-200 cover ½ to 2 HP. Each power rating has a single-phase and three-phase complete pump item number in the ordering table.

Is a Franklin Electric FAC ½–2 HP pump self-priming?

No. The FAC is an end-suction centrifugal pump that must be primed before startup. Check the suction configuration, foot valve and manufacturer instructions for your installation.

Which FAC impeller fits my pump?

Use the exact model family: 305453017 (FAC-50), 305453018 (FAC-75), 305453019 (FAC-100), 305453020 (FAC-150) or 305453021 (FAC-200). Verify the model and installed configuration before ordering.

What is the FAC ½–2 HP mechanical-seal part number?

The manufacturer’s FAC ½–2 HP parts brochure lists mechanical shaft seal 305463029. Send your exact pump model and nameplate details for parts verification.

Can I replace a FAC gasket with an O-ring?

Not without checking the pump configuration. Franklin distinguishes pumps built before March 2015 from later O-ring assemblies. Quote the pump model and existing joint design when requesting replacement parts.

What are the maximum flow and head for the FAC ½–2 HP series?

The small FAC brochure states up to 60 GPM and up to 130 feet of head as separate series specifications. Actual operating flow depends on the selected pump and system head.

How is the FAC ½–2 HP series different from the 3–5 HP range?

The ½–2 HP pumps use compact 56J C-face motor configurations, smaller NPT connections and their own repair-part mappings. The larger FAC models use different motor and component configurations, so their impellers and seal parts should not be substituted without verification.

Request a Quote for a FAC Pump or OEM Replacement Part

Complete pump: send your desired FAC model or item number, motor voltage and phase, expected flow and head, and installation details.

Replacement part: send the FAC model, manufacturer part number or exploded-view figure reference, plus a nameplate photo when available. Ken’s Distributing Company can confirm fit, pricing and availability when you request a quote or call 303-699-7845.
