?     Asked on 4/24/2017 by Vince Corso

My pump motor capacitor cover has rusted out and the wiring to the capacitor is now tripping the circuit breaker. The motor part number is 355340S. It's a 1 HP Single Phase 230/115V 3450 RPM motor. Can I go with a 1 1/2 HP pump and get more circulation? Do I need anything else besides the pump like gaskets?

A     Answered on 4/26/2017 by Lennox H.

Hi, Vince. Yes, you could replace the motor along with the Impeller and seal or replace the entire pump if you would like to increase the pumps hp. The motor you currently have has a total hp of 1.65. If you are to increase the hp of the pump you will have to go to a 2.2 hp pump or motor.

?     Asked on 4/13/2017 by

my motor just gave out ... can't read info on it ....seems to be part #10-177475.20 I see 1hp for $188 and a 1.5 for $174 should I get the larger one?

A     Answered on 4/13/2017 by Scott W.

I would go with the B854. Both the B854 and B848 have a total horsepower of 1.65 and are basically the same motor, but the B854 is $14 less.

Hi I need to replace A.O. Smith motor Part# O-193986-24 Serial # 18210CH for Plus HP pump model# PHPF1.0 is B2848 the correct replacement motor?

A     Answered on 3/30/2017 by Matt S.

Hello Mandi, yes the B848 is the correct motor replacement. Also, the correct part number begins with a zero. The part number is 0-193986-24.Do not forget to replace the shaft seal during the motor replacement. For the PHPF, you will need to find the pump housing's serial number; a serial number P08FF0001 and later uses the new style, anything before number uses the old style.

Hi, What is the difference between B2848 and B2841 pool pump? Thanks, ken

A     Answered on 1/31/2017 by Scott W.

There is not much difference besides the amount of amps each one uses. The B2848 is the standard motor that uses 8 amps at 230 volts and the B2841 is the energy efficient motor that uses 7.4 amps on 230 volts. So with that specific motor there really is not a difference as far as energy saving is concerned.

Hi Keith. The Century B849 motor is the correct replacement for p/n 0-177896-22. If you replace it with the B2848 motor you will need to change the impeller also because it has a lower total horsepower than your original motor.

A     Answered on 7/20/2016 by Scott W.

Yes, that motor will fit but you need to make sure your filter is able to handle the increased flow rate from that motor. The total horsepower on the B848 is 1.65 so it would almost be a full horsepower more than the .75HP

Looking for a replacement motor for a Pentair Whisperflow. Unit says it is a 1.5 HP 1.10 SF making it 1.65 HP. The part number appears to be either 7-177475-20 or 7-177475-28. Concerned about my motor burning quickly (5-6 yrs) and want to keep the expense down. Better to get higher or lower SF motor? What do you suggest? Also - I see various "tune-up" kits (gaskets, etc.) but have read some folks report the parts were incorrect in the kit. Need recommendation based on your motor suggestion.

My current motor is a Pentair 177475-20 which is supposed to be compatible with this motor. All the specs are the same though this is listed as a 1hp instead of the 1.5hp of the Pentair. Am I correct that the shaft of this will work with the impeller of the Pentair Superflo pump that uses the 1.5hp impeller?

A     Answered on 2/22/2016 by Andy O.

Hello Roger, The B848 1 HP Standard Motor - Full Rate (B2848) will replace your current A.O. Smith motor. The 177475-20 comes up as a 1 hp full-rate or 1.5hp up-rate.

I believe this is the correct replacement for my Magnatetek Century Centurion part # 7-177450-03, all other nomenclature matches, y56y frame, 230/115V. This is paired with a Whisperflow WFE-4 pump. I added solar thermal panels 6 months ago and all has been fine until the motor recently seized, my question is do I need a bigger pump/motor to push the water to the roof, is that possibly why the 10 year old motor failed? Also please recommend the gasket kit for this pump.

A     Answered on 9/15/2015 by Hector F.

This is a correct motor replacement for you. 10 years is a good life span for a motor. On average a total horse power of approximately 1.5 as this motor has, is good enough for a solar system. The seal kit for the Whisperflo on a regular chlorine pool is the gokit32 and the salt water version is the gokit32salt.

I need to buy a replacement motor for my Jandy Stealth SHPF 1.0. I know the B2848 is correct as that's what I have now, but in reading previous Q&A there are seals/gaskets/o-rings that need to be replaced when swapping out the motor. It seems like I need a Jandy GoKit based on responses to prior questions but I did not see a Jandy GoKit listed on the site. Can you post links to all of the recommended replacement seals/gaskets/o-rings for my pump when a motor is replaced? Thanks

A     Answered on 8/25/2015 by Charlie R.

Scott,Unfortunately, the Jandy Stealths do not have a tune up kit. You have to purchase all the seals separately. The mfg recommends replacing at least your shaft seal whenever you replace your motor. You can find all your Jandy SHPF replacement parts here.

Hi Brian, The A.O. Smith 1 HP, 56Y Frame, Up-Rate Motor (B2853) will be the correct replacement motor for your Whisperflo WF-24 Pump. I would also recommend getting the Pentair/Purex Whisperflo Tune Up Kit.

?     Asked on 8/9/2015 by Bert

This seems to be the proper motor for a Pentair Challenger 1 HP. However, it is a "56 frame", while the one that just died is a 48 frame SQ1102(we bought the house 3 years ago, the pool is about 13 years old, I guess the motor was replaced already). Would this 56-frame motor fit, or should I just replace with the exact same motor (SQ1102)? Thanks. your site is awesome, by the way....

A     Answered on 8/11/2015 by Hector F.

Usually the 56 frame style motors were originally used on the Challenger models so I would go with the B848. Functionally though, they both can work.

I have an Pentair Intelliflo VF so what parts would I have to swap out(Impeller, diffuser,kit,) to do a motor replacement with this one please? Also, what is the impeller screw I need for this and is it the same size as the Intelliflo impeller screw? Thx.

A     Answered on 6/17/2015 by Hector F.

The impeller part number that you would need is 5074-27c and the diffuser part number you'd need is 5074-13a. The impeller screws are exatly the same being part number 5074-14.

my 5 yr old Pentair dynamo motor runs hot, sometimes almost too hot to touch. Is this normal or is the motor on it's last leg?

A     Answered on 6/16/2015 by Dennis R.

Ron - Motors do run hot especially in a hot climate. But there are conditions that make them run hotter than they should. See our guide on "How To Troubleshoot a Pool Pump Motor - Motor Overheated" for more information

I have a very old, 30+ years, Anthony Antho-Sweep A.O. Smith pump, model number (best I can read it) C48K2EBJ02, Frame 48Y. Would this pump work as a replacement. I know this one is a 56Y frame but I'm reading in some places these might be usable to replace a 48Y?

A     Answered on 6/11/2015 by Patrick P.

The motors can be 56Y and 48Y swapped with no problem. The difference between the 56Y and the 48Y motor is the width of the barrel, the 56Y motor is wider then the 48Y motor. Sometimes when going from a 48Y to a 56Y, the base has to be cut to fit the larger motor.

I see that this is a replacement for the Centurion 7-177475-20 motor, which I have on an Ultra-Flow pump, and is a 1 hp rated motor replacing a 1.5 uprated motor. What would happen if I put the 1.5 full rated (B2854) motor on my pump?

A     Answered on 5/31/2015 by Alex V.

Tom, Aside fromt he higher horse power motor costing more to operate, you will not see any added benefit unless the impeller is upgraded as well.

I have the whisperflo wf-26 pump with pentair motor 7-177475-20. Is this the correct replacement? Thanks

A     Answered on 5/16/2015 by Andy O.

The B848 1 HP full rate motor for your WF-26 pump. We would also suggest the replacing the Shaft seal on your WF-26 pump as many times if you use your old shaft seal you will have leaking which will cause damage to the new motor. A leaking shaft seal will also void the motor's warranty.

My pump motor has part #7-168453. It shows to be a 1 1/2 HP Centurion, type CX, code J. Is this the correct replacement motor?

A     Answered on 5/11/2015 by Patrick P.

Hi Dennis, Yes this would be the correct replacement for your 7-168453 motor. The reason this motor shows 1 HP and yours shows 1-1/2 HP is that this motor is a full rate motor and your motor is an uprate motor and a 1 HP full rate motor is identical to a 1-1/2 HP uprate motor. So you should be all set with going with this B848 motor.

my 1hp Magnetek motor (8-177080-24 230/155volt Y56Y SF1.65) made a scrapping high pitched noise the other day that only Rosanne Barr would have appreciated...so i turned it off. The next day there was just a humming sound. A buddy and i opened the motor, cleaned it, replaced the bearings and now ready to reattach it to the pump but want to get the correct seals and gaskets. The pump is cast iron with what looks like engraved on the strainer body, C3-29D on its lid and 01-63DA on the pump.

A     Answered on 4/28/2015 by Patrick P.

Hi Jeff, I can confirm that this is the proper replacement motor for your Magnetek 8-177080-24 motor. For the seals and gaskets I would need to know your pool pump manufacture name and model # as I was unable to cross reference any of the part #'s you supplied. Based on the part #'s you supplied I believe this is most likely a Sta-Rite pump, model names for Sta-Rite would be Max-E-Glas, Max-E-Glas II, Dura-Glas, Dura-Glas II, C Series, CC series, etc.. Also is the strainer housing plastic, cast iron or bronze? Please email us back with this information and/or any pictures of your pump, as this will help us determine the needed seals and gaskets.

My part # is 7-193993-05 is this the right motor for replacement? my pump model is SHPF 1.0

A     Answered on 4/27/2015 by Patrick P.

Hi Craig, Yes this would be the correct replacement motor for your 7-193993-05 motor being used on your Jandy SHPF 1.0 pump. We would also suggest the replacing the Shaft seal on your Jandy SHPF 1.0 pump as many times if you use your old shaft seal you will have leaking which will cause damage to the new motor. A leaking shaft seal will also void the motor's warranty.

I have a Jandy pool pump system. The pump motor is making noises. It is an A.O. Smith 1.5HP part number 7-193986-24. Also, what seals would you recommend replacing?

A     Answered on 2/24/2015 by Robert M.

The correct replacement for your motor is model B854. The seals would depend on your Jandy model (Plus HP, Max HP, Stealth, WTFR, or Flo Pro). You can find the replacement seals on those part pages. I would recommend replacing the shaft seal, diffuser o-ring, and backplate o-ring.

I am shopping for a new pool pump motor (mine is starting to make noise). I now have a Pentair 0-177450-3 1HP motor and looking to replace it with the B848 motor. Will I have to have a different shaft seal for my Whisperflo WFE-4 pool pump?

A     Answered on 1/19/2015 by Robert M.

Hello Wade - You could replace your current motor with the B848. The shaft seal would be the same regardless of the motor.

What is the difference between the B2841 and B2848 motors?

A     Answered on 1/7/2015 by Brian M.

The difference between the B848 and the B841 is the amps it takes to run them. They are both Energy Efficient motors and both have a Total Horse Power ( horse power times service factor ) of 1.65 hp. The B841 is just slightly more efficient by running at an amp usage of 7.4-7.8 at 115v or 14.8 at  230v. The B848 will run at 8 amps at 115v and 16 amps at 230v.

?     Asked on 1/7/2015 by Wade

Is the B848 pool pump motor suitable for outdoor pool pumps?

A     Answered on 1/7/2015 by Brian M.

Yes, this motor will work just fine for either indoor or outdoor applications. The motor is determined by the wet end that it is being attached too. A motor cover is recommended for outdoor use to protect from rain, sprinklers and the runoff from the roof,  rusting the motor prematurely.

?     Asked on 1/5/2015 by Wade

I just finished replacing the shaft seal on my booster pump. As soon as I turned the pump on water was leaking from the shaft seal. Is it defective or am I doing something wrong?

A     Answered on 2/16/2012 by Patrick P.

Depending on the model, the installation of a booster pump shaft seal can be slightly different than a pool pump shaft seal. Some booster pump and pool pump shaft seals require that a silicone sealant be used on the outer areas of the metal seat of the shaft seal. The seal will need to be lightly hammered into the body of the pump. You can use a 1 inch PVC coupling or a piece of 1 1/4 inch PVC pipe and a rubber mallet. This procedure will apply to any pool pump or booster pump using a >PS-1000 style shaft seal.

Why should I purchase a Tune Up Kit?

A     Answered on 1/12/2012 by Patrick P.

A Tune Up Kit includes all of the essential replacement seals and gaskets for the pump. The seals and gaskets should be replaced when installing a new motor on your pump. New seals will prevent the pump from leaking water or losing the prime. A Tune Up Kit will protect your motor and ensure that the pump is working efficiently.

?     Asked on 1/12/2012 by Guest

Why do I need to purchase a new shaft seal?

A     Answered on 1/12/2012 by Patrick P.

We strongly recommend replacing the shaft seal. The purpose of a shaft seal is to prevent water from running down the shaft of the motor and into the motor housing. Water will damage the bearings and cause the motor to fail. A new shaft seal should be installed whenever a motor is replaced. The motor manufacturer can deny the warranty if the motor fails to due to water damage from a faulty shaft seal. To find your shaft seal you will need to visit our Pool Pump Parts Page or the Spa Pump Parts Page and select your make and model.

What is Service Factor?

A     Answered on 1/11/2012 by Patrick P.

Service Factor(SF) is a multiplier that when multiplied by the horsepower of the motor indicates the total permissible horsepower loading that may be carried when the motor is operating at rated voltage and frequency. The most important thing to remember when replacing a motor is that the replacement motor's horsepower times its service factor must be equal to or greater than the original motor's horsepower times its service factor. The Service Factor rating can be found on the motor label. See Step 4 of our How to Read a Pool Motor Label guide.

 (5 out of 5 stars)  Pool Filter Motor

from Bowie, Maryland ()

Pros: Customer service, shipping time, price and product

Cons: None that I can think of

Best of all is the wonderful customer service help provided by Inyopools. The product was here in the time specified and the price was considerably less than the 5 other companies I checked with first. The product was as specified and ordered and hasn't given me any problems to date. It was installed about a month ago.

 (5 out of 5 stars)  Great Customer service - packing could be better


Incredible customer service. Delivery of pump was "ok"....took about a week, but I selected the cheapest shipping option. In the process of assembling the new pump, so I cant review the pump yet. One bit of constructive criticism: Dont use popcorn as packing material! They ended up getting shredded in the shipping process, and found their way into the pump itself. Took about 20 minutes blowing it all out. Air/bubble wrap would have made for a much cleaner unpacking experience
