Finding a Motor for A Swimming Pool Pump

If your swimming pool pump is starting to run loudly or making strange noises, it might be time for a new pump motor. Though replacing a motor can seem daunting, we’re here to help you easily identify your replacement motor.
Starting off, It’s important to note, the total horsepower (Service Factor x Horsepower) of your new motor needs to be greater than or equal to the total horsepower of your old motor. Below is a picture of a pump label, where you’ll find all of the information you’ll need when purchasing or replacing your pool pump motor.
Pool Pump Service Tag
We’ve highlighted the most important considerations: horsepower, voltage, amperage, hertz, service factor, and phase. Matching up these items on your new pump will ensure that your water will be filtered correctly. We also recommend that you purchase a go-kit that includes new shaft seal gasket and other miscellaneous gaskets and seals that should be replaced.
Now that you have a idea of what you will need, replacing your pool pump motor yourself will save you money and make you more knowledgeable of how your pool filtration system works.

    I have a Jandy pool pump with motorJHPU2.0. it is an A O Smith motor s/n BY03-13 p/n 8-19363-24 2 hp Voltage 230/115 Amps sf 9.2/18.4 60 hertz rpm 3450 type CX P56J phase 1 Which motor should I get for a replacement?

    • PoolSupplyWorld

      Hi Al, in speaking with the manufacturer, they did not recognize the part number of the motor you specified (8-19363-24), as the middle group of numbers (19363) should have six numbers and the part number you mentioned has only five. If you could please recheck the part number of your motor and relay the full number to us, we would be more than happy to help you find the proper replacement motor.

    • PoolSupplyWorld

      Hi Tim, in order to determine the proper replacement motor for your pool pump, we would need to know the make and model number of your current pump motor. If you could please provide us with the make and model number, we’ll be happy to help you find the proper replacement. Thanks, and have a great day.

    Hi Looking for a replacement motor for my Doughboy power pak III. 1 or 1.5 HP will do. Doghboy #’s 300-1091 and 300-1092. Thanks, Tim

    • PoolSupplyWorld

      Hi Tim, thank you for your question regarding a replacement for your Doughboy Power Pak III. Are you looking for a UL or NEC model motor? If you are looking for a 1HP UL motor, you will need the Power Pak III 0-1076-000. If you are looking for a 1HP NEC motor, you will need a Power Pak III 0-1076-006. We do not currently carry either of these motors at PoolSupplyWorld, but if you could please contact us, we would be happy to work with you on a special order.

  • Don

    I have a Hayward Super Pump with a AO Smith 1HP motor wired for 115v. I was wondering if there was a more efficient motor I could put on this pump?

    • PoolSupplyWorld

      Hi Don, when replacing a pool pump’s motor, it is important to consider horsepower, voltage, amperage, hertz, service factor, and phase in order to ensure your water will be filtered correctly. If you could provide us with the said information, we would be more than happy to steer you toward the right, efficient replacement pump motor.

    • PoolSupplyWorld

      Hi Larry, before we could give you a proper recommendation on a replacement motor for your pump, we would need a bit more information. While you provided some of the specs of your motor, if you could please provide us with the voltage of the motor, and most importantly (in determining the correct replacement), the model number of the motor, we would be more than happy to help you find the proper replacement motor for your pump.

    • PoolSupplyWorld

      Hi David, in order to find you a proper replacement motor for your Pentair WF-28 WhisperFlo Up-Rated Standard Efficiency 2HP Pool Pump – 22.4/11.2A 115/230V, we would need a bit more information from you on your current motor, including: shaft size, face, voltage and HP. Also, is the amperage you are specifying 10.5/21.0? It is crucial in replacing a pump motor that the specs match.

      From the specs you gave us, we believe a comparable pump motor from a different manufacturer would be the Emerson 56 Y-Frame Hayward TriStar Single Speed 2HP Up-Rated Premium Energy Efficient Pool and Spa Motor – 10.8/21.6A 115V/230V, however, before we can definitively recommend this motor to you, we need to be certain it is, in fact, the proper replacement. On another note, to prevent future issues with a new pump motor, make sure the wiring voltage matches the motor voltage (230v or 115v). If the voltages don’t match, the motor could burn up.

      Also, be sure to read the section on page four in your pump’s owner’s manual on “Care of Electric Motor”. You can find the owner’s manual linked as a PDF to your pump’s product page. If you could please provide us with the requested information, we would be happy to help you find the correct replacement motor for your WhisperFlo pump.

    • PoolSupplyWorld

      Hi Terry, thanks for your great question. Yes, we do carry the motor for the Hayward Super Pump 1-1/2 HP pool pump. You can find it on our site listed as the Hayward Super Pump 1-1/2HP Replacement Pool Motor. We would also recommend that you replace your shaft seal assembly when you change out the motor to prevent water from leaking into the new motor. For this, you’ll want to go with the Hayward Pool Products Inc. OEM Seal Assembly. Please let us know if we can answer any other questions or assist you in placing an order.

Thanks

    • PoolSupplyWorld

      Hi Ed, in speaking with the manufacturer of your pump, the Pentair Challenger pump you have given us the part number to, model number 355460, does not match up to the A.O. Smith Centurion motor you mentioned, as the pump is a 2 HP pump and the motor is a 1-1/2 HP motor.

      Based on the motor’s serial number and part (7 168 453-24) you provided, the manufacturer of the motor suggests the A.O. Smith Century 56Y Square Flange 1-1/2 HP Up-Rated Pool and Spa Pump Motor – 8.0/16.0A 115/230V as a replacement motor, but before we can recommend it for certain, could you please re-check the part numbers on both your pump and motor, so we can be sure you will be getting the proper replacement? Thanks, and have a great day.

  • Jane and Mike

    My newer pool and pump is only three (3) years old. The Pool Pump is an EMERSON “Star Pump, SmartMax(tm)” SP3207Z1MR. Model: K63CXFEL-4992, RPM: 3450, Volts: 230/115, HZ: 60, PH1. This pump has “rusted out” with a rust hole in the side of the Pump. The Sticker reads: “For Replacement Parts, Visit [www.bluehaven.com].” These people “DO NOT RESPOND or ANSWER ANY PHONE CALLS.” All other parts are “HAYWARD.” WHY? Would they not have a “Hayward Pump” for continuity? Can you help me/us with a New Replacement Pump that Fits the Other Parts and INFO. Provided? Thank you, we are most appreciative! Jane & Mike

    • PoolSupplyWorld

      Hi Jane and Mike, we’re sorry to hear you’ve been having problems with your pool pump. We’ve forwarded your inquiry to our customer service and support team, and a representative will be in contact with you shortly to help you find the replacement pump and parts you need.

  • P Best

    Like a previous inquiry (Patrece ), I have a A.O. Smith E-Plus Energy Efficient 56Y Square Flange 2 HP motor that I believe has a bad capacitor (hums but won’t spin). The motor is about 4 years old, so replacing the capacitor seems a reasonable solution. Do I need to disassamble the motor to determine the specs on the capacitor in order to get the right one? Would you likely carry the capacitor? I noticed that the capacitor sits atop the motor, can it be replaced without having to remove the motor?

    • PoolSupplyWorld

      Hi P Best, to determine the part number of your pool pump motor’s capacitor we would need to reference the motor’s model number or serial number, both of which you should be able to find on the name plate on your motor. If you could please provide us with this information, we’d be happy to help you track down the proper replacement capacitor and its installation procedures.

  • Danny Pringle

  • Steve White

    Hello, I need a replacement pump for our pool. The previous home owner moved the pump and filter from the spa to the main pool probably because he didn’t want to spend the additional money. I am interested to know if the Pentair IntelliFlo 3HP Variable Speed Ultra Energy-Efficient Pool Pump – 011018 will work as my main motor and what additional pieces would be required. I need it by the third week of march delivered to my home. Thanks Steve

    • PoolSupplyWorld

      Hi Steve, the Pentair IntelliFlo 3HP Variable Speed Pool Pump is an extremely energy efficient pump that is a great addition to most pools, but whether it will be a fit for your pool depends on your pool type and size, as well as the current equipment and number of features you operate. The IntelliFlo VS can be set to run at up to eight different speeds (between 450 and 3,450 RPM) for up to eight different pool or spa functions. It is equipped with 2″ unions, and works best with 2″ plumbing. To better determine if the IntelliFlo VS or another pump would be the best fit for your pool, please feel free to give us a call, and one of our friendly, knowledgeable customer service representatives will be happy to assist you.

    • PoolSupplyWorld

      Hi Vicky, if your pool pump is a Hayward Power-Flo and the motor is actually labeled with part number SP1510-Z-1-XE, not XB, the proper replacement motor is Hayward Pool Products Inc. Motor 1 HP with Switch. If you have further questions or would like to make sure this is the proper motor for your pump, please contact us for immediate assistance.

    i have a jandy stealth 1.5 hp motor. Need a replacement. Whatdo you recommend

    • PoolSupplyWorld

      Hi Lynn, in order to recommend a suitable replacement motor for your Jandy Stealth pump we will need to know the part number of your current motor, and the part number of your pump, if possible. If you could please provide us with these numbers, we will be happy to recommend a replacement. If you cannot find the number, please provide us with as much information from your motor’s information plate as possible. Please feel free to contact us for immediate assistance.

  • ed

    I bought a StaRite pump for my inground pool from you a year or so ago. Can I replace the motor with a variable speed motor?

    • PoolSupplyWorld

      Hi Ed, while it is possible to replace your existing single-speed motor with a variable-speed, it would require replacing the motor, drive and impeller, and at that point, it is recommended to replace your entire pump with a variable-speed pump. If you can tell us the make and model number of your existing pump, we will be happy to find the pieces you need for a complete retrofit, or if you’d like, we can offer some great suggestions on variable-speed pool pumps, such as the Pentair IntelliFlo VS. If you have any further questions or would like immediate assistance, please feel free to contact us directly.

    We have a 17,500 gallon in-ground pool, free form, and we are located on the Gulf Coast of Central Florida.

Voltage 115/230 / Amperage 14.0/7.0 / Hertz 60 / Service Factor 1.25 / Phase 1. Please recommend an energy efficient alternative, preferrably with an energy efficient variable speed pump.

  • Stephan

    Hello, we are purchasing a home that has a small/medium in-ground pool (sorry, I don’t know the number of gallons). The previous owner stated the motor burned out, so I would like to replace it soon. It currently has a AO Smith motor attached to a Jandy Stealth pump (1.5HP). I would like to see about upgrading to a Pentair VS or VF. Can you tell me if this would be a good match? Here are the motor specs: AO Smith,part #7-193633-24, Type CX, FR: P56J, Phase 1, 60Hz, 3450 rpm, 230/115 volts, Amps SF 9.2/18.4. Thank you!

  • Nate

    We have a free form pool. 3 waterfalls and 2 separate motors. 1. 1hp motor single speed for waterfalls. 2. One 11/2 hp filter pump motor 2 speed. The original setup was one 1 1/2 for the waterfalls. Worked for 8yrs. The second original filter pump motor 3hp. worked for 8 yrs. The new 1hp waterfall motor is the third pentair installed and had to be rebuilt. The new 11/2 hp filter pump motor only works on high for 5min then drops down to a very low speed that will not even move the in pool sweeper around. We have to turn on the water fall motor and the filter pump motor to clean the pool. We were told the original motors were too much power. Really our total bill for electric is 185.00. Run time used to be 4hrs. Now our elec. bill is 200.00 and we have to run the two motors together, when they work, for 16hrs and the water fall for 2hrs. Originally, 3hp for 4hrs Now 2 1/2hp for 2 then 16hrs. This is not a savings and I have been told in California this is what Edision Electric wants. Can you help? Nate

    • PoolSupplyWorld

      Hi Nate, we definitely understand the frustrations that come with energy consuming pool pumps and costly electrical bills, and it is pool configurations like yours that benefit the most from variable speed pumps. Rather than single and dual speed pumps that consistently stay at one high speed, variable speed pumps are designed to switch between low and high speeds depending on the application desired. This is critical to lowering energy use and reducing high utility bills.

      For example, the Pentair IntelliFlo VS is a great choice for pools with multiple features, including general circulation, waterfalls, pool cleaners and more. It includes eight different speed settings to choose from, ranging from 450 RPM to 3450 RPM and uses an integrated timer that allows you to set different speeds throughout the week, which means it will switch between higher and lower speeds at the times you choose. For example, you can set the IntelliFlo VS to run at a higher RPM for your multiple water fountains for two hours, before setting it at the lowest RPM for general circulation.

      Because you have multiple waterfalls, it is also recommended to take a look at the Pentair IntelliFlo VF. Like the IntelliFlo VS, the IntelliFlo VF offers multiple speeds to choose from and includes a timer to set speeds throughout the week. However, it is designed to automatically adjust its speed to maintain the flow rate chosen, and therefore it is a great option for pools with water features that require a certain water pressure. As with the VS, the IntelliFlo VF is a suggested way to save on high energy bills.

      If you’re interested in choosing a new pump, we welcome you to give us a call for immediate, one-on-one assistance. A customer service representative will be happy to offer any advice on energy saving tips and variable speed pumps to help lower your electricity bills.

  • derek smethurst

    I have a skc38sn6084ax marathon pump HP1 V115/230 HZ 60 SF 1.25 PH 1 the back piece that attaches to the basket via 4 bolts has cracked – the piece that I have to hook up to the pump by clamping it together is cracked – how can I replace that part and how much will it cost. Many thanks.

    • PoolSupplyWorld

      Hi Derek, it sounds like what you are experiencing is likely a cracked seal plate. At this time, no replacement parts are manufactured for Marathon motors, and therefore you will need to replace your entire pump. To determine the best pump for your pool, could you please provide us with your pool’s type and size, your filter type and size and the features you have on your pool (automatic cleaner, waterfall, spa, etc.). If you would like immediate assistance, please feel free to contact us directly, and a customer care agent will be happy to assist you.

    Hi. I have pentair superflo pumps and they are always breaking or at least that is what my pool guy is saying. Want to know if the Challenger series is a very good pump for a pool that has an inground system, waterfall, and spa. I have four pumps. one for filter, one for cleaner, one for spa and one for waterfall. My inground system has been average. I have a 1 hp motor on it now. Is it better to go to a 1.5 for better pressure.

  • Troy

    I have a AO Smith Century Centurion that needs replacing. Part 7-177475-20. The impeller is also shredded. What do I need to buy?

    • PoolSupplyWorld

      Hi Troy, the part number you provided is for your pump’s motor only. While you could replace it and your impeller, it may be more prudent to replace your entire pump. If you prefer to replace the parts alone, you can replace the motor with the Century A.O. Smith Centurion 56Y Square Flange 1-1/2 HP Up-Rated Pool and Spa Pump Motor – 16.0/8.0A 115/230V.

      With this motor, you should also replace the seals and o-rings, but in order to recommend the proper kit, and in order to recommend the replacement impeller, we will need to know the make and model number of your pool pump itself, not just its motor. If you can provide us with this information, we will be happy to make a recommendation. For immediate assistance, please feel free to contact us directly.

  • Mark

    I have a AO Smith Centurion switchless pool pump motor that needs replacing. The model number is 7-193987-24. What is the replacement for it? Also, what seals and o-ring will I need?

    • PoolSupplyWorld

      Hi Mark, in order to find the correct replacement motor, we would need to know the horsepower, voltage, and frame size of your existing motor. If you can also provide us with the make, model, and part number of your pump, that will not only help us find the motor, but the proper seals and o-rings, as well. This will help us narrow down the correct parts you need.

  • Billy

    I have a AO Smith Century Centurion motor Part# 7-177475-20 that started making a sporadic noise. I turned off the power to the pump and then turned it back on. Now it only makes a buzzing noise so i turned it right back off. I checked the impeller it’s not broken and the shaft turns. What do you think might be the problem? Perhaps something internal with the motor maybe?

    • PoolSupplyWorld

      Hi Billy, a buzzing noise can be caused by debris stuck in the impeller. You can remove the motor from the pump to access the impeller and make sure it’s clear of debris. If you’ve cleared all debris and it’s still making noise, then we recommend contacting the manufacturer for additional troubleshooting steps. If it’s something internal with the motor, we suggest consulting a qualified pool technician to come out and check out your equipment. Please let us know if we can be of further assistance.

    We have a Jacuzzi 1 HP SPL by A.O.Smith. 60 Hz Amps .8 Part # 7-186533-22 When we turn it on all it does is buzz. I looked at the impeller and could not see anything blocking it, but I will remove the motor and look again. If it still buzzes, what do you recommend we replace it with. We have an on ground Wilkes Genesis pool with a 6 ft deep end. Approx 13000 gal.

    • PoolSupplyWorld

      Hi Tom, if your pool pump’s motor is humming softly but not turning on, it sounds like something my be wrong with either the run capacitor or the start capacitor. At this point, you will need a qualified service technician to take a look at your motor to both identify the problem and troubleshoot it.

      If you decide you do need a new motor, the correct replacement motor that you’ll need is the Century A.O. Smith Century Flex-48 48Y Thru-Bolt 3/4 HP Single Speed Above Ground Pool Motor – 9.8A 115V

    I have the AO Smith C48K2N143B1 PUMP. Which is a 1HP pump. It seems to be burning out. My pool is a 23k gallon DE pool. Can I upgrade to 1.5 HP or should I go even higher? Should a 1HP pump be enough. My pump doesnt seem to be pulling enough water through the system.

    • PoolSupplyWorld

      Hi Peter, You can go either way with that pool size 1 or 1.5 HP. If you don’t feel you are getting adequate circulation with a 1 HP pump go ahead and switch to 1.5 but keep in mind that your electric bill will go up. Let us know if you have any questions!

      Hi Warren, You could replace that motor with the one linked here. You will also want to replace the seal with the generic replacement linked here as the OEM seal is no longer available. Most times it’s also a good idea to replace the gasket which you can find linked here. Let me know if you have any questions! -Christian

  • Kevin Sternberg

    I need to replace the motor on a 10 year old Pinnacle in ground pool pump. Part number looks to be 7-177474-01. It’s a 1HP motor with the following specs: Volts – 230/115, Amps – 7.1/14.2, Hertz – 60, Service Factor – 1.25, Phase – 1, RPM – 3450, Type – CX. Serial number is BY03-17. Any suggestions? The quieter and more energy efficient the better. Thanks!

    • http://www.poolsupplyworld.com/ Daniel Henson(PoolSupplyWorld)

      I just want to confirm a couple other specs before I give you a recommendation. What is the Motor Frame(FR) and is this a single or dual-speed? Thank you.

  • Kevin Sternberg

    Not sure what you mean by motor frame but I believe it is a square flange. Also is a single speed motor. Thanks!

  • whw

    I have a noisy AO Smith Century Centurion motor attached to a Pentair impeller head for my in ground pool/spa combo with constantly running waterfall on the spa. Pool is 33k gallons and uses a Jandy membrane filter. Control is with a Jandy RS-8. I would like to replace the pump with either a 2 speed motor or perhaps a Jandy multispeed pump. Here are the specs:

    AO Smith CAT B858 S/N 011103M Part 7-177081-24 Type CX FR y56y HP 1.5 SF 1.5 PH 1 HZ 60 RPM 3450 Volts 230/115 Amps SF 10.5/21.0 Time Cont Encl DP Form KJM Code K

    Pentair Impeller Head: Pentair Challenger P/N 345201 pmp CHII N1 1.5F S/N 0301321090030L

    Would a low speed pump push water thru the spa at a fast enough rate? I don’t know how important that is, but I imagine that if the water just trickles over there will be a lot of evaporative loss? Also, the pump would need to integrate with the Jandy control panel. I believe there is a Jandy 2 speed relay that plugs into the panel? Finally, would a Jandy multispeed pump be a better choice? I’ve steered away given the cost so far, but would appreciate any comments.

    • Dylan (PoolSupplyWorld)

      You are going to have a few replacement options for yourself. For a dual speed replacement motor you would be interested in B2983. This motor will be a suitable replacement to what you currently have. However, this motor does need to be wired at 230V, your old motor could have been wired either 115V/230V. If for some reason you also were interested, the B2983T is the same motor with a digital timer already included on it for you (in case you changed your mind about the automation). The dual speed motor relay kit you would need is going to be part 6796.

      Now as for a variable speed pump I would recommend the Jandy VS FloPro (VS-FHP2.0). At the very top speed it is just going to be slightly weaker than what you currently have, but once the RPM level starts going down then the flow chart evens out with your existing pump. This shouldn’t be an issue for you but I at least wanted to mention it. As for being integrated with your automation, what letter revision is your controller? If it is revision O or later then it will work seamlessly, if your revision is prior to this then we will have to upgrade the board.

      To answer your last questions, whether the water is pushed through your spa at a quick enough rate will depend on a number of factors. The distance from pump to spa and what exact RPM you set the pump on. The good thing about the variable speed pump is that you will be able to fine tune the RPM to find what works best for your pool and spa. Let me know if you have questions about any of this! And feel free to contact our sales staff at 800-772-0467.

      • whw

        Dylan, thanks for the reply. I do have a rev. QQ RS-8 so I think we’re OK with that. While it’s a big difference between $300 and $870, I’d hate to run into trouble with the spa overflow. What is the low flow rate for the AO Smith B2983?

        • Dylan (PoolSupplyWorld)

          Unfortunately there is not a flow chart that I have available for the B2983 as the Pentair Challenger doesn’t actually have a dual speed model offered. The motor itself doesn’t specify what the flow rate is, it is a combo of the motor and the Pentair Challenger wet end. I would not be able to provide any exact numbers for you. Let me know if there’s anything else I can help with.

          • whw

            Thanks again. Am thinking a true variable speed pump might be the way to go. The issue is that I have a pool/spa combo with the return to the spa. If the low speed is not enough to break the surface tension on the overflow I’m concerned I’ll run into evaporative loss. Is there a practical difference between the Jandy e-pump and the Jandy VS FloPro? Do those come with the needed RS panel relay/controller devices?

          • Dylan (PoolSupplyWorld)

            I would agree that a VS pump would be the way to go. Being able to adjust the flow rate will allow you to find the lowest possible flow without having to worry about the issues with the spa overflow. One of the key differences between those two pumps is that the ePump does not have a controller included with it. The ePump can be controlled with your AquaLink RS (must be revision O or later), the ePump Off-Board remote control (purchased separately), or an AquaLink PDA system. On the other hand, the VS FloPro comes with a control already included and all programming can be done on the pump itself.

  • Zachariah Ellingson

    I would like to replace my noisy northstar pump with a variable speed pump. Are there any replacement motors that would fit my pump housing, or would I need a whole new pump + housing.

    Attached is a picture of the label from my pump.

    Thanks!

    • Dylan (PoolSupplyWorld)

      Unfortunately none of the variable speed motors that we currently have available would be compatible with the Hayward Northstar pump. The design of the pump housing won’t fit with the VS motors and their included controls. Your two options would be to either go with the direct replacement of your current motor (SN1152). Or you can upgrade to an entirely new variable speed pump, which includes both the motor and wet end. Give us a call at 800-772-0467 and we would be happy to discuss either option with you.

    Need a replacement motor for a Pentair pump that has given up the ghost very suddenly. Shaft spins by hand but there is a loud hum when I try to turn the pump on with no action from the motor…as if it is binding somewhere in the internals.

    Label shows CHII N1 1.5A 346206 with a motor number of 168453

    60 Hz 1PH kW

    On the thermal protection line, it shows KA Code J

    No reference to form, so not sure if I am looking at 48 or 56 or something else

    Confusing things is that the motor number googles back as a 1.0HP on every site I saw while the label clearly indicates it was a 1.5HP motor.

  • Alden

    I am looking to upgrade my current pool pump. I know nothing regarding pool
    pumps and I am NOT at DIY person. My current PG&E bill is skyrocketing and
    it seems most of my usage is when my current pump is at work. I’m assuming my
    15+ yr old (may be older, I have no idea) is the culprit.

    Questions:

    1. From my pics sent, how old and in-efficient is my current pump?

    2. What is the best “low cost” replacement should I buy????
    (something that does not cost too much initially, and good on using less power/electricity)

    3. If I buy a pump from someone like PSW, whom should I have install it? And
    approx how much $$$ is a reasonable cost for this?

    4. Are there PG& rebates I could use for purchasing a new pump?

    Any help would be greatly appreciated.

    • Dylan (PoolSupplyWorld)

      Great questions and I would be happy to answer anything else you think of:

      1) Your current pump is an Pentair WhisperFlo Energy Efficient model 011514. It’s actually not too bad of a model to have and you could certainly be doing worse for yourself. That model is definitely still in production and at this moment has a price of $533.99.

      2) My strong recommendation is going to be the Pentair IntelliFlo Variable Speed 011018. While this pump is currently at $866.07 and would thus be a bit more expensive up front, over the long run it is going to save you a ton of money. Homeowner’s that convert over to an IntelliFlo find that they can save in the range of 70%-90% off of their current energy bills. Meaning that you are basically going to get your money back on the pump within just a year or two. Another reason this would be a great choice is that it is a direct plumbing replacement to what you currently have. You wouldn’t need to change your piping at all.

      3) We do not have any install service ourselves. If you happen to be in the Sacramento, CA area then give us a call and we can probably get you a couple numbers. I would recommend locating a few pool companies in your area and getting a quote from each of them on what they will charge for the install. If you did happen to go with the IntelliFlo that I mentioned it will be really easy. All that needs to be done is reconnect the plumbing and attach the wiring. The install cost can really vary but I wouldn’t imagine much more than roughly a $100.

      4) PG&E does currently have a $100 rebate available for variable speed pumps, such as the IntelliFlo mentioned. You can view the rebate form if you visit PG&E’s website and search for their pool pump rebate. A standard single speed (what you have now) or dual speed pump would not be eligible for this same rebate.

      I would suggest giving us a call at 800-772-0467 or visiting our LiveChat service. We can answer any further questions you have and help you pick something out that will work well for your pool. Have a nice day!

  • kellyslane

    Is this a correct match?, WhisperFlo WF-23 and USQ1072. The brand new USQ1072 (with 73126 impeller) shut down in thermal overload after running @ 10 minutes. Electrical tester shows 15A draw when motor running. Nothing else changed in equipment configuration. Thanks

    • Dylan (PoolSupplyWorld)

      The USQ1072 has the correct horsepower level to match your pump, but would not be the one I would recommend first. A direct replacement for the WF-23 is the Century AO Smith B852, this will have the exact same specs as the original motor. Now the USQ1072 does have a higher amp rating, this higher amp rating might be the reason why it isn’t operating properly. If you have any other questions that I can help with then let me know. Thanks!

      • kellyslane

        Your diagnosis was spot on. I switched to B2852 (new repl model) and the system works perfectly. Thanks much.

        • Dylan (PoolSupplyWorld)

          Glad to hear you were able to get the issue figured out! Hopefully your pool is running fine now and looking blue. Have a good rest of your day and if anything else comes up feel free to get in touch.

  • alblank07

    Hi, very informative site!
    I have a situation with my pool that I hope you can help with. I inherited my pool with the house we purchased. The pool is 18 X 36 and it was installed with only one water supply to the pool from the pump, which is installed in the deep end. Most pools I have seen have at least 2, one at the deep end and one at the shallow end. We converted to a salt system this summer. Even though we maintain a good chlorine level, and the water is clear, I am still seeing patches of green algae on the sides/floor of the pool.
    Could this be a water circulation problem? The pump & motor are pretty old, I assume, and the motor just died and will need to be replaced. The motor is a Heyward 1 HP, model # C48K2N143B1, and I believe all of the piping is 2″. My question is, would a larger pump/motor help with this situation? Thank you.

    • Dylan (PoolSupplyWorld)

      Only having one return jet could be a factor leading to the growth of algae in the pool as you don’t have ideal water circulation. Unfortunately there isn’t much to be done now to adjust that return jet situation. Having a larger pump would cause there to be a slightly stronger flow of water coming out of the return and hopefully be able to push the water farther throughout the pool. You would not want to move up too large in the pump size, only about 1/2 HP, and we would want to check what size your filter is to ensure that won’t be overpowered. The motor you have does work with a few different pump models, so maybe you have more information on the pump model itself? My guess is the Hayward Super II, in which case this would be your pump:

      http://www.poolsupplyworld.com/Hayward-SP3007X10AZ2-Super-II-Up-Rated-Single-Speed-1HP-Pool-Pump-115V230V/SP3007X10AZ2.htm

      To go up in size with the same Super II, I would suggest the following pump that will have a total horsepower of 1.50 (as opposed to 1.10) you currently have:

      http://www.poolsupplyworld.com/Hayward-SP3010EEAZ-Super-II-Energy-Efficient-Full-Rated-Single-Speed-1HP-Pool-Pump-115V230V/SP3010EEAZ.htm

      Seeing that these pumps are on the more expensive end, I might suggest looking into upgrading to a variable speed pump. That would be a whole different convo and I might suggest giving one of our sales reps a call at 800-772-0467 for help picking one out. Thanks!

  • Gail

    Hi, my motor has died out and I’m looking to replace the motor, but can’t seem to find it anywhere. I’m not sure it’s because it’s part of a pump inherited with the house. The motor is a Hayward/A.O Smith, model #K48N2N104. Using the above formula with a SF=1.25 and HP=2. The ideal horsepower I’m looking for is a 2.5. Which motor would you recommend? Thanks for the help in advance.

    • Dylan (PoolSupplyWorld)

      The suggested replacement motor for your current model is going to be the Century A.O. Smith ST1202 at the following link:

      http://www.poolsupplyworld.com/Century-AO-Smith-ST1202-56J-C-Face-2-HP-Single-Speed-Full-Rated-Pool-Filter-Motor-126-114A-208-230V/ST1202.htm

      To determine the total horsepower of your current motor, you take the service factor and multiply it by the horsepower, to then give you a current total horsepower of 2.5 HP. This new ST1202 motor is going to have the same specs and have a total horsepower of 2.5 HP, just like your existing one. Now if you were looking to move up in the horsepower of the pump, we would need to know a bit more info about the whole pump model number, pictures can help. Feel free to give us a call at 800-772-0467 for further help. Thanks!

    • Dylan (PoolSupplyWorld)

      Hi Paul,
      Would you happen to have a CAT or part number off of that motor label? Or if not, what is the entire pump model? Is it Pentair, Hayward, Jandy, etc.? And the model name?

      • Paul

        I took a photo what’s on the pump

        Thank you for responding

        • Dylan (PoolSupplyWorld)

          Paul,
          The good news is that CAT number makes it real easy to find the motor on our website. That CAT number would be considered the manufacturer sku# (which is how we label items on our site). So long story short, here is your direct replacement:

          http://www.poolsupplyworld.com/Century-AO-Smith-B230SE-56J-C-Face-2-HP-Up-Rated-Pool-and-Spa-Pump-Motor-92184A-115230V/B230SE.htm

          As for replacing the motor, I would suggest searching YouTube for videos on how to replace a pool pump motor. The process is very similar between most pumps, and there are some good instructional videos out there. One additional thing I would recommend is a replacement Go-Kit (replacement seal kit). To be able to recommend the correct one I would need to know the enter pump model, and not just the motor number. So any further information labeled on the pump (not the motor label) would be helpful.

          *And for some reason I don’t see the photo came across*

          Thanks!

          • Paul

            Thank you Dylan

            Unfortunately that number you provided isn’t pulling up too much as to what brand or model the pump is. If you have some pictures you can go ahead and send them directly to my email (dlane@poolsupplyworld.com). I’ll take a look and see if I can identify the pump.

      • Paul

      Let me know if you have questions about either one of these products. Take care!

      • Cody

        The original is 2.5HP and the replacement is 2HP. What difference will that make?

        • Dylan (PoolSupplyWorld)

          Actually, the motor is going to be identical in the horsepower. The motor manufacturers have a funny way of showing the Total Horsepower rating. To determine the Total Horsepower (which is the real strength of the motor), you would use the following calculation:

          Horsepower (HP) x Service Factor (SF) = Total Horsepower

          In the case of the information you gave me off your motor:
          2.5 HP x 1.04 SF = 2.6 Total Horsepower

          The B2843 that I recommended is the following:
          2.0 HP x 1.30 SF = 2.6 Total Horsepower

          As you can see the strength of the motor is the same, and the AMPS are the same as well for both motors (11.0-10.2). The motor manufacturers generally play with the HP vs. SF ratings so they can make one motor appear to be “Stronger”, and therefore “Better”. Ultimately between the two motors we are discussing there are no differences. I’m happy to answer further questions.

    I’m trying to replace a 1.5 HP Pentair pump. It’s got two part numbers on it – one is 7-168453-24, the other is 35-5340. Can you direct me to a replacement? Thanks…

  • James

    Okay, I have a Pentair Part: 7-177452-03. VOLTS 208-230, AMPS11.0-10.2, PH 1.
    The label on the next part of the pump says WhisperFlo Model NO. WFE-3. HORSEPOWER 2.5, SERVICE FACTOR 1.4. Help with a replacement is appreciated :)

    • Dylan (PoolSupplyWorld)

      Hi James,

      Some of the information that you provided does seem to conflict a bit. That WhisperFlo model WFE-3 would actually be a pump that has a total horsepower of 1.25 and an amp rating of 11.2/6.0-5.6. Now the motor model number of 7-177452-03 does correspond with a motor that would match the horsepower and amp ratings you read off of it. Is this by chance not the original motor that came with the WFE-3 pump?

      In any case, based on your motor information, the recommended replacement would be sku# B2843 at the following link:

      This motor matches the specs you gave me for the 7-177452-03. I would also suggest a replacement seal kit at the following link:

      Let me know if you have further questions, thanks!

      • James

        Thank you for your response. We bought the house with the pool in place so it it possible it has been changed. The stickers showing the information I listed are on two different ‘housings’ if you will. The part saying WhisperFlow is on the housing of the cleanout part with the basket. Our pool guy seems confident with the information. Thanks again.

    I have a Jandy Pump Model: SHPF1.0 with an AO Smith Motor: Part: 7-193993-05 / Rated HP 1.0 / SF 1.65 / PH 1 / Frame Y56Y / HZ 60 / RPM 3450 / Volts 208-230/115 / AMPS SF 7.8-7.4/14.8.

    Can you please help me with the motor and seal part numbers?

  • Felix Hernandez

    I’m replacing a 1 HP marathon CAT # C1318 single speed, Service factor 1.0, with 56 J frame and C face motor with a possible emerson EUST 1102 or A. O. Smith UST 1102. I would prefer a quieter and more efficient motor. Does that imply more HP, and or more speeds or variable speed? If I do upscale, how much electricity costs do I save, and does the hayworth pump-impeller have to be changed too? Thank-you

      Hello Felix,

      To start off, I would suggest that if you want to upgrade HP to just buy a new pump. Replacing a pump motor on it’s own is a complicated process, but to get it to work with a different HP is much more difficult. In case you do plan to upgrade to a higher HP motor, you will have to at least replace the impeller. Depending on the motor you might have to replace other parts as well.

      You are correct though, if you were to get a Variable speed motor it will be much more efficient. The energy costs are depending on where you are of course. Here is a calculator on our website to help you check that out –

      Please let us know if you need anything else, and feel free to call or chat in! Have a great day.

    The Mrathon is difficult to fit due the house wall and is 11 inches long. Is the Emerson, which appears stocker by photo, have a shorter length that would be welcomed?

  • Paul Dalton

    Pump stopped. It came with the house, probably pretty old: it’s a PAC-FAB Challenger 1.5HP (P/N 35-5459) with a Magnetek B842 1.5HP Century E Plus motor (I think the current model is B2842). I’d like to know what options I may have other than just replacing the dead motor with the current version of the same thing. For example, is there a more energy efficient single speed motor I should consider? Or is there a variable speed motor that could be attached to this pump to make it even more efficient than just a better motor? If not, which variable speed pump system do you recommend I consider to replace this Challenger pump system? In case it makes a difference, I don’t have any existing electronic control system for any part of the pool system. Thanks.

  • Derby

    I have an existing Century Centurion A.O. Smith switchless motor pump. The specs are:
    HP: 1.0 SF: 1.25 HZ:60 RPM: 3450 VOLTS: 230/115 AMPS: SF 7.1/14.2 PH: 1 What comparable motor can I buy that comes with the motor plus the filter basket (mine is cracked on the lid) Thanks in advance for your help.

  • ALE

    I have an Emerson 1081 Pool Motor, Model K63CXESF-4793, what are some comparable replacement motors available?

  • P Best

    The tag on the pump does not list Model Number, but does have a serial number: 35907CH. It does say Century Centurion on on the top of the tag. The “Part” is listed as O-193995-07

  • PoolSupplyWorld

    Hi P Best, we are researching a replacement capacitor for your motor based on the additional information you provided, and someone will be in contact with you shortly regarding an answer. As for the installation procedure, since your capacitor sits atop your motor, you will not have to take the motor apart. All you’ll need to do is remove the capacitor cover, unlock the old capacitor, put the new one in and replace the cover. Thanks for you patience. We’ll be in contact soon!

    Hi Danny, as a replacement for your Hayward Super II pump’s existing motor, part number C48K2N143B1, either the A.O. Smith 56J C-Face 1 HP Single Speed Up Rated Pool Filter Motor – 15.0/7.5A 115/230V or the A.O. Smith 56J C-Face 3/4 HP Single Speed Full Rated Pool Filter Motor – 15.0/7.5A 115/230V will work. These are identical motors. The only difference between them is the 1 HP motor is up-rated while the 3/4 HP motor is full-rated.

    To better understand up-rated versus full-rated motors, feel free to check out our Basic Guide to Understanding Pool Pump Motors, and if you have any further questions, please feel free to give us a call.

    Hi S., for your 17,500 gallon free form pool, we highly recommend the Pentair IntelliFlo VS. This variable-speed pump can save up to 90 percent on energy consumption when compared to standard single-speed pumps. With the IntelliFlo VS, you can set up to eight custom speeds between 450 and 3,450 RPM to meet your pool’s needs, and its built-in timer allows you to program a weekly performance schedule. The IntelliFlo VS is built with an extremely-efficient permanent magnet motor and has a totally enclosed, fan-cooled design that promotes durability, longevity, high-quality performance and quiet operation. If you have any further questions on the IntelliFlo VS or other variable-speed pumps, please don’t hesitate to ask.

  • PoolSupplyWorld

    Hi Stephan, either the IntelliFlo VS or IntelliFlo VF would be a great replacement for your Jandy Stealth pump, but which IntelliFlo is right for you will depend on the type of control you are looking for as well as the equipment on your pool. The IntelliFlo VS can be manually programmed for up to eight custom speeds while the IntelliFlo VF will automatically self-set and self-adjust to meet the flow rate needs of your pool. You can learn more about the differences between the two pumps in our IntelliFlo VS and IntelliFlo VF Comparison blog.

    If you have a solar heating or in-floor cleaning system, we would recommend the IntelliFlo VS over the VF because the change in water pressure caused by your solar or in-floor cleaning system may trigger the built-in blockage detection system in the VF, causing the pump to shut off.

    When installing an IntelliFlo pump, we highly recommend contacting a local pool service technician. If you have further questions about which IntelliFlo pump is right for you, please feel free to give us a call for immediate assistance.

    Hi James, thank you for your interest in a pump for your 200,000 gallon pool. A member of our sales team will be in contact with you shortly to help find the pump that is right for you.

    Hi Tom, in order to recommend the proper replacement motor and impeller for your pump, we will need to know the part number of your pump itself. Unfortunately, the number you provided does not give us enough information to go by. If you could please provide us with your pump’s part number, we would be happy to recommend the appropriate replacement parts. For immediate assistance, please feel free to contact us directly.

  • PoolSupplyWorld

    Hi Sun, the Pentair IntelliFlo VS is an excellent, energy efficient and quiet pump that can certainly work with Hayward Goldline products, but you will not be able to control the functions of your Goldline products from the IntelliFlo’s built-in control. The IntelliFlo VS can be programmed for up to eight precise speeds to meet the needs of your pool and applications, including a Goldline solar heating system or salt chlorinator, but it will not know exactly what it is controlling.

    If you have a Hayward automatic control system, you can install a Pentair IntelliComm II Interface Adapter in order to allow your IntelliFlo to communicate with your Hayward control. If you have further questions, please feel free to call us for immediate assistance.

    Hi Sam, the Challenger pump is definitely more powerful in comparison to the Superflo. With an output of about 30-35GPM, you can stick with a 1HP Challenger pump. Was your Superflo not giving enough flow to your system? If not, then the Challenger will be a great choice. If you’re looking to increase flow to your water features, a 1.5HP will work.

    Because you have multiple pool features, you may want to consider replacing your multiple pumps with a variable-speed pump, like the Pentair IntelliFlo VS. The IntelliFlo VS is a 3HP pump that is designed to meet the precise needs of your pool, and can be programmed for up to eight different speeds for a variety of pool applications, including general filtration, an automatic cleaner, spa and waterfall. Aside from its versatility, one of the major pluses with the IntelliFlo is that it can save up to 90% on energy consumption when compared to a traditional single-speed pump. Please note, if you operate a pressure-side cleaner that uses a booster pump, you will still need the booster.

    If you have any further questions about replacement pumps, please feel free to give us a call for immediate assistance.
