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 bought this to replace my broken single speed motor. I'm currently running 8hr/day using the old single speed motor. How long do I run the new motor in one day? Should i just double the time for low speed?
Reply
If you currently run your single speed for 8 hours, you could run the new motor on low speed for twice as long. This will still cut your energy consumption in half.

I am interested in the above replacement motor. I can receive a rebate from my electric company if the motor is Energy Star certified.
Is this motor Energy Star certified?
Thank you

Hi, Stu. Replacement motors are not eligible for rebates or Energy Star certified only complete pumps. If your electric company offers any rebates for pumps they would have a list of eligible pumps.

Hello I was wondering if this motor will mount to a pentair single speed superflo wet end? I got a pic of my motor. I would be running it 115v. Also if not this motor do you have another one in mind? And love to change to a dual speed without installing new plumbing. Thanks!!!!
Mike, yes the Pool Motor Square Flange 3/4 HP 115V Full Rate Dual Speed w/ Digital Controller - B2981T would fit your single speed Pentair Superflo pump.
