I need to replace my Sta-rite motor #196249. I am looking at your PureLine PL2853, AO Smith B2853, and AO Smith B2661. Will they all work as replacements, and how can I estimate the energy savings by going to the higher efficiency motor to see if it justifies the higher price? Also what seal kit would I need?

 Reply

A  Answered on 10/25/2019 by InyoPools Product Specialist Lennox H.

Hi, Don. You can use either option and use our How Much Does My Pool Pump Cost to Run? guide to calculate operation cost. You will also need the SuperMax Tune Up Kit - GOKIT78.

Can you recommend the options I have to replace this motor with a square flange

A  Answered on 6/13/2019 by InyoPools Product Specialist Matt S.

Hello - this motor is a 56J round flange motor; a square flange is not able to mount to the same pump housing. Your replacement motor would be the 3/4 HP Round Flange 56J Full Rate EE Motor - B127.

?     Asked on 3/14/2019 by Craig

I have a Pentair WhisperFlo which is leaking between the motor and the pump. My pool service says that the motor bearings are also sounding bad and a new motor is needed. Taking them at their word, I'm having trouble identifying a replacement motor. My current unit is a model WFE-3, 0.75 HP / SF 1.25 / 115V. Your website shows this motor is not California Title 20 compliant and I live in the Golden State. Replacement motors appear to have a higher HP rating. What direction can you offer?

 Reply

A  Answered on 3/14/2019 by InyoPools Product Specialist Lennox H.

Hi, Craig. The A.O. Smith 3/4 HP Square Flange 56Y Dual Speed Full Rate Motor - B2981 is the replacement motor that will work for your application. You will also need to get the Toggle Switch - 2512558-001 and the Whisperflo Tune Up Kit - GOKIT32 or GOKIT32SALT

Hi Rockie, Based on the motor information you supplied you will require the B2840 2.5 HP Replacement Motor. To determine the seals you require we would need for you to send us a photo of your pump to include where the plumbing goes in and out of the pump. To send the photos simply reply to this email with the photo or you may email to upload@inyopools.com and state you are looking for a seal replacement.

Should I use this to get energy savings by replacing the motor in my SuperFlo 340038 (1 HP x 1.25 SF), or should I get the 1HP EE instead? Is a variable speed even better? What are approx differences in electric consumption between the three? (25,000 gallon in-ground, pump 2' above water line, and pushes an additional 8' up to solar water heating)
 Reply

A  Answered on 3/18/2016 by InyoPools Product Specialist Lennox H.

Hi Sam, You can use this motor verses the B854 to achieve "good" energy savings, a Dual Speed motor B2981T will offer you "better" energy savings and a variable speed motor ECM16SQU will offer you the "best" energy savings. Between all these option you can cut operation cost by 33-80 percent.

I have just replace the motor from my pool pump with the B661 from Inyo Pools but when I turned back the electricity the rotor does not turn and all it does is a loud hum. I have removed the motor from the pump and verified that the rotor rotates freely. Does this motor only come with one capacitor inside the top hump? I checked the capacitor with a digital multimeter and it appears to store charge okay. Can you please advise on my next step? Thanks Patrick

A  Answered on 2/8/2016 by InyoPools Product Specialist Lennox H.

Hi Patrick, Confirm the voltage that the motor is wired for, either 115 or 230 volts. If the motor is wired and set to the correct voltage setting and you're still having problems, let us know and we can get a replacement sent out under warranty.

As long as there is no leaks or cracks in the pump housing you should be just fine changing the motor and shaft seal part number (gokit32). Also just double-check the impeller and diffuser and any o-rings you may come across, They should all be round, If any are flat they will need changed.

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?
 Reply

A  Answered on 2/16/2012 by InyoPools Product Specialist 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?
 Reply

A  Answered on 1/12/2012 by InyoPools Product Specialist 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?
 Reply

A  Answered on 1/12/2012 by InyoPools Product Specialist 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?
 Reply

A  Answered on 1/11/2012 by InyoPools Product Specialist 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.

The bearings on my American Products Ultra Flow Pump Siezed

Written on 1/9/2018 by Guest

Always Lock Out / Tag Out power source when working on electrical equipment!!!

My Motor had been sqealing for some time and the bearing finally gave up the ghost.
I contacted INYOPools for a direct motor replacement via Email
INYOPools team provided me a direct link to the part
Ordered part and within a couple of days pump motor arrived
In the link were instructional videos with how to remove the motor and install various motors / pumps. While similar, there were a couple of differences. I supplemented my knowledge with several external videos while waiting for the pump to arrive.
While I easily removed the motor, I had a challenge removing the rear seal. Nothing I did could separate it from the motor.
I went to a local pool supply and was luck enough to find a replacement rear seal and picked up Tune Up Kit including Shaft Seals (I neglected to buy these at the same time and these are *critical*)
Once I had all the parts on hand, I watched the video one more time.
In less than 20 minutes hands on work, I had the new motor installed and working in the existing pump.

Lessons Learned - Buy the Tune Up kit if buying just the replacement motor; Watch the videos suggested by INYOPools; watch other videos too.

Always Lock Out / Tag Out power source when working on electrical equipment!!!
