Franklin Electric builds close-coupled end-suction centrifugal surface pumps in five families — AG, D, FAC, HC and XS — that between them cover fractional-horsepower transfer duties up to large flanged water-handling installations. They serve irrigation districts and farms, municipal and commercial water systems, construction and mining sites, HVAC and industrial plants. The families differ in hydraulic range, connection type, casing and impeller materials, seal construction and motor configuration, so the right choice is set by the duty point and the installation, not by horsepower alone.
We supply the U.S. 60 Hz range in NPT and flanged configurations, plus the pump end kits, seals and JM or JP motors that keep them running, and select each pump against the manufacturer’s published curve for your flow, head, liquid and electrical supply. Call 1-888.510.4036 and we will size it for you. Genuine Franklin Electric equipment, factory-new in original packaging — sold and supported by Watermain Supply, an independent industrial supplier.
Will It Work for Me?
Four checks that settle most centrifugal pump orders before you open a curve.
Warranty
Franklin’s limited warranty on its end-suction centrifugal pumps runs 12 months from installation or 24 months from manufacture, whichever occurs first, per the End Suction Centrifugal and FAC owner’s manuals. Full terms and conditions are in the manufacturer’s manual.
Reliability
Stainless impellers on AG, FAC and HC; back-pullout construction and replaceable shaft sleeves on AG, HC and XS; silicon-carbide seal faces on FAC and HC. Pump end kits, seals and JM or JP motors are sold separately, so a worn pump is rebuilt rather than replaced.
Fit
Clean water to 212 °F. Working pressure 120 psi (FAC), 150 psi (AG, D), 250 psi (XS) or 350 psi (HC); inlet pressure plus shut-off head must stay inside it. NPT on D and FAC, NPT or flanged on AG, flanged on HC and XS. These are not self-priming pumps: the suction must be flooded or primed.

Start with D and AG, and use FAC for a compact 3–5 HP, 2 in × 2 in NPT duty. In every case the selected model curve, not the family ceiling, decides the pump.
What changes between the families
Comparison
Practical distinction
AG vs D
Both list 150 psi and threaded selections. AG also offers flanged versions and stainless impellers throughout; D impeller material varies by hydraulic model. AG ceilings are 900 GPM / 325 ft versus 650 GPM / 300 ft for D.
FAC vs D
FAC is the focused 3–5 HP, 2 in × 2 in NPT option; D spans more hydraulic sizes and a wider horsepower range. FAC uses silicon-carbide seal faces and FKM elastomers; the D catalog describes carbon/ceramic faces with nitrile as standard.
AG vs HC
AG offers NPT and Class 125 flanged selections; HC uses Class 150 flanges and a ductile-iron volute. HC limits extend to 1,900 GPM, 450 ft and 350 psi.
HC vs XS
HC has the higher head ceiling (450 ft vs 180 ft); XS the higher capacity ceiling (2,000 GPM vs 1,900 GPM). XS is 1,800 RPM only; HC includes 1,800 and 3,600 RPM designs. These figures do not establish a direct replacement.
Franklin vs Grundfos, A.Y. McDonald and Goulds
We supply all four brands, so here is where each wins. Competing figures come from our own product pages for those lines; price positions are from our current prices. Above about 3 HP and 150 GPM, the Franklin AG, D, HC and XS have no close-coupled end-suction competitor on our site.

Honest verdict. For a small residential booster or lawn-irrigation transfer under 3 HP, the other brands cost less: the A.Y. McDonald Workhorse has the lowest entry price, the Grundfos CM is a compact multistage that builds up to 182 ft at 24.8 GPM, and the Goulds GT is the only one that re-primes itself when it has to lift from a pond or tank. The Franklin D Series wins once the duty grows or has to last: a 150 psi rating, sizes to 50 HP and 650 GPM from one family, stainless impellers on the DA models, and pump end kits, seals and motors on our site so a worn pump is rebuilt rather than replaced.

Honest verdict. Match the pump type to the duty: an end-suction centrifugal is the efficient choice for high flow at moderate head, a Super Booster for a small flow that needs a lot of pressure, and a vertical multistage VR for mid-range flow at high head. We size all three and quote the one that lands nearest its best-efficiency point.

Sizing & Best Practices
How we size a centrifugal pump, and what to check before installing.
1. Calculate required boost
Required boost = target pressure at the highest outlet + 0.433 psi per foot of elevation + friction loss at design flow − available inlet pressure. Worked example: a three-story building with the highest fixture 30 ft above the pump, 45 psi wanted at that fixture, 12 psi of friction loss at design flow and 40 psi city inlet needs 45 + (0.433 × 30) + 12 − 40 ≈ 30 psi of boost — about 70 ft of head (30 × 2.31). Select a model that delivers roughly that head at the design flow, read from the curve.
2. Estimate peak flow honestly
Size flow to simultaneous demand, not the sum of every fixture. Convert water-supply fixture units with the Hunter method (IPC Table 604.3 and Appendix E); for single- and multi-family dwellings, the IAPMO Water Demand Calculator gives lower, more realistic peaks for modern low-flow fixtures. For irrigation, size to the largest zone. Oversizing pushes the pump left of its best-efficiency point and shortens seal and bearing life.
3. Check model limits
Confirm inlet pressure plus shut-off head stays under the working-pressure limit, the 212 °F maximum liquid temperature, available NPSH at the design flow, and the enclosure (ODP vs TEFC) for the environment. Match connection type and size — NPT versus flanged, and the flange class — and remember a flange-class number is a joint rating, not the pump’s working-pressure limit.
Sizing rule of thumb. If the duty point lands past about 70 percent of a model’s maximum head at the design flow, step up a model — it leaves headroom for friction the estimate missed and keeps the pump off its steep end. Run the numbers in our booster pump sizing calculator or see Pump Curve 101.
Rated Performance
The catalogs publish family ceilings and model curves, not tabulated duty points, so we quote the nominal ceilings and select from the curve — we never invent curve points.
The figures in the comparison above are the highest capacity, head and working pressure each family reaches somewhere across its models. They do not occur together: a pump at its maximum flow is near zero added head, and a pump at maximum head is near zero flow. The usable duty point sits between those extremes and is read from the curve for the specific model, speed and impeller trim.
Working pressure is a separate equipment limit from the head the pump adds. A 350 psi HC casing rating is not a 350 psi pressure rise; the curve sets pump-added head at the operating flow, and inlet pressure adds on top of that when you check the casing, seal and piping limits.
Head to pressure. Boost in psi equals head in feet multiplied by 0.433. A pump adding 100 ft of head raises pressure about 43 psi. For the exact model, request the manufacturer curve and read head, efficiency, power and NPSHR at your design flow.

A stainless-steel impeller does not make the whole pump stainless. Confirm all wetted materials and elastomers against the liquid; catalog options and repair-kit configurations can differ from the standard construction summarized here.
Connection type
NPT and flanged versions need different piping. Match suction size, discharge size and flange class — and do not read a flange-class number as the pump’s working-pressure rating.
Motor speed & trim
An 1,800 RPM selection and a 3,600 RPM selection are not equivalent, and impeller trim shifts the curve. Match the complete catalog model when replacing an existing pump.
Service access
AG, HC and XS use back-pullout construction; HC and XS add casing jack-out holes. The volute stays piped while the rotating assembly comes out.
Seal materials
Faces and elastomers differ across families — carbon/ceramic with nitrile on D, AG and XS; silicon-carbide with FKM on FAC and HC. Match them to the liquid, not to the pump size.
Close-coupled design
The impeller rides on the JM or JP motor shaft, so there is no coupling to align and the footprint stays short. Replacement motors are matched by frame letters.
Add constant pressure
These are pump-and-motor units. For constant pressure, pair the three-phase models with an X-Drive CEN panel and a pressure transducer.

Frequently Asked Questions
For contractors, maintenance teams and buyers comparing Franklin Electric centrifugal pumps.
What warranty comes with a Franklin centrifugal pump?
Franklin’s limited warranty on its end-suction centrifugal pumps runs 12 months from installation or 24 months from manufacture, whichever occurs first, per the End Suction Centrifugal and FAC owner’s manuals. Full terms and conditions are in the manufacturer’s manual.
Which series has the highest published flow capacity?
The XS catalog lists capacity up to 2,000 GPM, followed by HC at 1,900 GPM, AG at 900 GPM, D at 650 GPM and FAC at 150 GPM. These are family limits; actual flow depends on the selected model and system head.
Which series has the highest published head?
HC lists head up to 450 ft, then AG at 325 ft, D at 300 ft, XS at 180 ft and FAC at 160 ft. Maximum head and maximum flow are not simultaneous operating points.
Which Franklin centrifugal pumps have threaded connections?
D Series uses NPT connections and the FAC has 2 in × 2 in NPT. AG includes both NPT and flanged versions. HC and XS use flanged connections.
Should I buy a Franklin D Series or a cheaper small centrifugal?
For a small residential booster or lawn transfer under 3 HP, the A.Y. McDonald Workhorse, Grundfos CM and Goulds GT cost less, and the GT re-primes itself. Choose the Franklin D Series when you need 150 psi, more than 3 HP, stainless impellers or rebuild parts on the shelf. We supply all four.
Are these pumps self-priming?
No. The AG, D, FAC, HC and XS are end-suction centrifugals that need a flooded suction or a primed, airtight suction line. For suction lift from a pond or tank, look at a self-priming pump such as the Franklin FBSE or the Goulds GT.
Does a 350 psi working-pressure rating mean the HC adds 350 psi?
No. Working pressure is an equipment limit, not the pressure rise the pump produces. The selected curve sets pump-added head at the operating flow, and inlet pressure must also be considered.
Can I select a replacement by horsepower alone?
No. Match the hydraulic model, speed, impeller trim, connections, voltage, phase and installation dimensions. Two pumps of the same horsepower can differ in performance and fit.
Can I rebuild a worn pump instead of replacing it?
Yes. Pump end kits for the AG, D, HC, XS and FAC bolt onto the existing close-coupled motor, and replacement JM and JP motors fit the existing wet end. Send the nameplate and we will match the order number.
What should I send for a quote?
For a replacement, send the complete nameplate, the factory order number if available, and piping or installation photos. For a new duty, provide flow, total dynamic head, liquid and temperature, suction conditions, voltage, phase and connection requirements.
