A.O. Smith Centurion replacement motor for Pentair WhisperFlo and Challenger full rated pumps. Specifications: HP = 3/4, RPM = 3450, Voltage = 115/230, Amps = 14.2/7.1, Service Factor = 1.65, Frame = 56Y, Shaft = Threaded. *Please Note: This is the correct replacement motor for the Challenger 3/4 HP full-rated pump.
I just replaced the bearings on my Whisperflo pump because it was making a loud noise. Still same noise. I guess I should replace the motor. Motor part# 0-177449-03. Could you tell me which motor I should get or what else could be the problem? Thank you, Mariska
You can either go with the B847, which is the standard 3/4HP full rate motor, or the B661, which is the energy efficient 3/4HP full rate motor. You will want the GOKIT32 as well.

I need to replace my pool pump motor...I have a B2847....I see you have them...which shaft seal would I need with it? Thanks
The motor does not define the shaft seal as this motor is a replacement part on many different pumps. I will need the make and model of your pump to provide the correct shaft seal replacement.
Hi I have a pentair pumps-n1-3/4a/340037 and motor# 196237, the motor is not working which one should I get? thank you
Hello, According to the model #340037 you have a Pentair Superflo 3/4 HP pump. For your reference, here is a link to the Pentair Superflo Parts list. I would recommend you replace your motor with the 3/4 HP Standard Motor - Full Rate (B847, B2847) and replace the shaft seal with the Pump Seal 200 (psr 200) 5/8".

Can you provide us the HP and Service Factor (SF) on the motor label, those are one of those most important things we need to double check it is the correct motor. Also, the pump model number PF-1-26-F02 does not cross reference to any pump housing. Can you verify this is the correct number from the pump sticker?

Does this motor replace the 0-177894-04
The BN25 Motor is the replacement motor for your 0-177894-04 motor
I have a century pool and spa motor 1081 part #7-196335-24 is this the same motor?
This is not the correct motor. The replacement model is a 5223X.
I have a Pentair pump model SF-N1-3/4A/346237, what is the replacement pump?
Ray- The b847 3/4 HP Standard Motor - Full Rate (B847, B2847) is the incorrect motor. The Correct replacement would be a B852 A.O. Smith 3/4 HP, 56Y Frame, Up-Rate Motor (B852, B2852).
I have a MagneTek Century Centurion 7-177474-81. Not sure of my HP. INYO POOLS recommends a 3/4 HP Standard Motor - Full Rate B847,B2847. On my label it says my amps are 7.1 14.2. On the recommended moter from INYOPOOLS is 6.6 13.2. Is this a concern? I just want to make sure I get the same HP and the correct motor. The motor I have lasted 16 years.
Hi Scott, The B847 will be the correct replacement motor. The amps is not a big concern other than it will cost you less to operate this motor. We recommend changing the shaft seal and o-rings when replacing the motor. If you can provide the manufacture and model of your pump housing, we can locate the correct parts for you.
I have a Purex Triton WhisperFlo H.P. Pump that the motor is going out on. I cannot read the Motor HP on the nameplate, but the Part No. is 7-168452-04; Frame:56Y; Form: KJM; Volts: 230/115; Type: OX. Can you tell what replacement motor I need?
Hello, Les. You can replace the Pentair / Purex Whisperflo Pump-Motor with A.O. Smith 1 HP, 56Y Frame, Up-Rate PART# B853.

Pretty sure this is the correct replacement motor - my current motor shows a part #: 7-177079-04. Other than this motor are there any energy efficient motors that would also work as a replacement?
Hi John, The A.O. Smith 3/4 HP EE Full Rate Motor (B661) will be slight more energy efficient than it's standard replacement.
I have a Pentair Whisper flow WF-24, what is the proper replacement motor and shaft seal kit for it?
I have a Pentair clean and the motor doesn't work. On the tag or decal of the motor it has model "LA0IN"; the motor details are 3/4HP, 3450 rpm, 230/115 volt, S56CX frame, type CX, Service Factor 1.5 continuous duty, ENCL D.P. Which motor is the correct replacement? Thank you!!!!
I have a pent air challenger with a p/n of 7-168452-04. Sticker on motor says it is a 1hp motor. The equivalent I see here shows a 3/4 hp motor?? What other seals etc will I need to swap out motor?
Shannon- The motor model you provided will be replaced by either 3/4 HP Standard Motor - Full Rate (B847, B2847) or A.O. Smith 1 HP, 56Y Frame, Up-Rate Motor (B2853) would have the same total hp. You can either go with the GOKIT5 which has the o-rings and the shaft seal or you can just get the the shaft seal which is part # 354545s.

Hello Erin, this motor does have a capacitor; that "hump" on the back is where it is housed.
Does this motor replace 7-177474-01?
Yes the B847 is the correct replacement motor.
I have a Pentair Whisperflo WFE-3 3/4 horsepower. Which motor is a correct replacement, B2847 or B2661? Thank you.
Hi Kurt, B2847 is the standard Full rated 3/4 HP motor: B2661 is the Energy Efficient [EE] Full rated 3/4 HP motor - uses 20% less amperage which equates to 20% less in operational costs.
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.
does this replace the 7-177449-03 3/4 hp type cx
For the 7-177449-03 you would actually need the B661 (B2661) Replacement Motor.
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?
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.
I'm trying to replace the motor on my pool pump but all these numbers and abbreviations on the motor label are really confusing me. What do they mean?
Replacing a pool pump motor is not as difficult as it seems. You can try looking here. If you need help figuring out what the information on your label means. If you are still having difficulty figuring it out you can call us at our toll free number or you can send us a photo of your motor label here.
Why should I purchase a Tune Up Kit?
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.
Why do I need to purchase a new shaft seal?
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?
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.

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.
