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 bought this motor about 4 years ago, Today when I try to run the motor, it makes a humming sound but does not run. Is the motor shot and need of replacement or could something else be wrong?
 Reply

A  Answered on 10/26/2014 by InyoPools Product Specialist Patrick P.

Hi Brad - The humming noise typically indicates that your capicator needs to be replaced. We have a great guide on How to Replace a pool motor capacitor I would take a look through it as it should be helpful on showing you how to replace your capictor. If you decide you are going to replace your capacitor then we have a second guide which shows you How to select your pool pump capacitor.

The pool pump suddenly stopped working

Found that the motor is broken, according to the parameters on the motor, find the matching motor on your website, and received it a few days after ordering.
