What is Service Factor?
Reply
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
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 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?

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
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.

(4 out of 5 stars) motor replacement
Reviewed By: mechanical max from Jacksonville, FL ()
Pros: perfect fit, very quiet operation
Cons: may need to replace additional parts
The new motor is very quiet. The seal plate and shaft seal also had to be replaced due to corrosion/failure adding to the total cost of the repair (might want to replace whole pump next time). I'm waiting to see if I realize any savings on my electric bill from this energy efficient motor.

(5 out of 5 stars) Motor replacement for OEM Whisperflo
Reviewed By: Phillip H. from Madison, AL ()
Pros: Easy to transfer the power leads, L1, L2, Grd.
Cons: Could not lock the rotor to ensure the pump was screwed on a tight. Tightened as much as I could then tightened center screw. So far so good.
I ordered the up-rate motor as a replacement to my 5-year old OEM Whisperflo. Excellent choice. Motor is quiet, seems to pump strong with less current draw. Looking forward to seeing how it affects my electric bill. I also replaced the Seal Plate and pump because they were damaged from scraping as a result of corrosion on the OEM bottom motor mounts. Actually tilted the pump to scrap the Seal Plate. Replaced all and runs better than new.

(5 out of 5 stars) Perfect replacment motor
Reviewed By: Craig J. from Fort Mill, SC ()
Pros: quick delivery and excellent packaging
Cons: none
From the packaging down to the rear cover this product was well done. Delivery was in 4 days, much quicker than I expected and the tracking was spot on and I knew when to take the other pump down in time to get the new one on. I will definitely use Inyopools again for my next replacment part.

(5 out of 5 stars) Pool Filter Motor
Reviewed By: DreamBigGoGreen 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.
