What is Service Factor?

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.

If using this product, and needing to replace the seals. What seal kit do I need to get for the product.

A  Answered on 3/8/2016 by InyoPools Product Specialist Andy O.

Hello Stephanie, The seals that will be used with the 5211x Motor 56j Thrd Up 1 Hp (b228se) would be determined by the model of your pump. Do you know what the model of your pump is?

I have an older Hayward pump. Don't see any numbers on it , but looks similar to Hayward SP2610X15 . What seal kit would I need to use with this motor replacement?

A  Answered on 3/24/2016 by InyoPools Product Specialist Lennox H.

Hi Glenn, If your pump looks similar to the Hayward SP2610X15, you will need p/n GOKIT3 or GOKIT3SALT. If you send us photos of the pump to upload@inyopools.com we can confirm which pump you have.

Pump motor quit working.

Written on 7/12/2021 by Guest

After consulting with a specialist on your website I picked the motor that he suggested. I received a one horse century electric motor and installed it on my existing Hayward pump. After hooking up all the piping I started the motor and the pump worked perfect.
