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.

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.

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.

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?
 Reply

A  Answered on 1/19/2012 by InyoPools Product Specialist Patrick P.

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.

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.

Pump would not turn when power on this spring. Had to remove pump and manually turn. Load whine due to bearings that had gone bad.

I used INYOpools.com in previous years and for my previous pump. Great service and parts. Excellent parts reference section for out of date or manufacturer changes. Ordered pump and seal. When they arrived, I just followed the INYO pools video for changing a pool pump. Took about one hour from start to finish. New pump is quiet and running great!!

Turned off all power. Then removed all wiring - took picture of the wiring for later use. Removed all nuts and bolts and separated motor from pump. Cleaned all parts. Reassembled parts to new motor and connected wiring. Restored power, and the new motor worked perfectly.

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!!!
