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.

I am wanting to replace a 1 HP Marathon 5KC38SN6084AX 3450RPM SF 1.5 with a 56Z frame. I don't see a 56Z frame as an option. What is compatible and what is the energy efficient version?
Reply
Hi Philip, The 56Z frame has been replaced with the 56Y's. The A.O. Smith 1 HP EE Up Rate Motor will be the energy efficient replacement for the Marathon 5KC38SN6084AX motor.

Hi Cruz, Based off of the info provided the Pentair WhisperFlo OEM Motor WFE-4 1HP Almond would be the original Whisperflo motor. That motor will have to be special ordered.I would also recommend getting the Pentair/Purex Whisperflo Tune Up Kit.

Hi, Dirk. A failing pump or motor will not cause an air leak. I would recommend using our How to Identify and Correct Air Leaks guide for more troubleshooting suggestions.

Is the 1 HP Motor EE - Up-Rate - B863SE motor a good replacement for the motor on Pentair pump WF-24C?

Yes the B863SE which is now called a B2661 is the energy efficient replacement motor for the WF-24C. When replacing your motor we also suggest a Pentair Whisperflo Seal Kit.

Is this the right motor for the Pentair CHII-N1-1A? The hp and sf match the motor I have.
