?     Asked on 10/1/2020 by Randy

what is the proper shaft seal for this motor
 Reply

A  Answered on 10/19/2020 by InyoPools Product Specialist Hector F.

Hi Randy, could you send us a few photos of your pump? Ideally, a wide shot showing the complete pump, including where the pipe goes in and out of the pump, and a second close up photo of the motor label. This would help us determine the proper replacement seals.

Can you please tell me if this pump motor would be the correct replacement for my current booster pump motor (pictured)? Also, what other parts or kit will I need in order to replace this motor. Thanks!

 Reply

A  Answered on 5/21/2020 by InyoPools Product Specialist Hector F.

The B625 is the correct booster pump replacement motor and in order to locate the proper seal kit or seals we will need to know the name or number of the front pump wet end model that the motor attaches to.

Is this pump motor the correct replacement for a Polaris Halcyon PB4-60Q ? What pump kit should I also purchase?
 Reply

A  Answered on 4/8/2020 by InyoPools Product Specialist Lennox H.

Hi, Danny. It is NOT, there is not a replacement motor that is currently available for that model pump. You will have to replace the entire pump with the PB460 model.

    Thanks for the info. I would also like your help in selecting a replacement motor for my pool pump. I am considering replacing both so that I would only incur one service call from the local pool dealer for installation. I currently have a Pentair Superflo pump. The specs on the motor are: Square Flange, Industrial class B, Volts 115/230, 1 HP, RPM: 3450 PH 1 Code J. Could you please recommend the appropriate replacement motor and also the Kit of seals and O rings for the installation? Thanks.

?     Asked on 2/28/2019 by Wayne

I have an A.O. Smith B625 booster pump that's 16 years old, tired and noisy. I want to replace it and I believe I also need the shaft seal as I have a slow water leak coming through the opening between the volute and the seal plate. What part number do I order to get the right seal? Also, does the existing motor stand come off so it can be swapped to the new motor?
 Reply

A  Answered on 3/8/2019 by InyoPools Product Specialist Lennox H.

Hi, Wayne. This B625 motor is the correct replacement. You will also need the Tune Up Kit Polaris Booster Pump - GOKIT71. Yes, the stand will come off and will need to be reused.

I have a Nidec B625 3/4 hp pool cleaner motor that is leaking oil or grease out the back. Is this from the bearings and does that mean the bearings need to be replaced? Is this something that would be covered under the 1 year warranty? Also, is the capacitor something that would be covered under the 1 year warranty?

A  Answered on 6/4/2018 by InyoPools Product Specialist Hector F.

Yes, this is typically covered by the manufacturer as long as it falls under the manufacturer warranty parameters. You can view the warranty card here

?     Asked on 8/4/2017 by Kurt

I too have this exact same problem: pump motor will run for a few seconds then it will cut off. If I don't cut power it will try to start up again in a minute but it will only power up for a few seconds then cuts off again. The pump is a Century A O Smith Part # 0-173840-23.... but I doubt it is wired wrong as it has been working for many years. If I order this motor does it include instructions on how to put it in the casing. I have never done this before. Thanks

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.

?     Asked on 1/11/2012 by Guest

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.
