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.

Can you direct me to the proper hi low switch for this motor?
Reply
Unfortunately the manufacturer does not offer the switch for the 2 speed 220v motors any longer. If you already have a 220 volt timer (on/off) you would need an Intermatic T106R to switch from high to low speed. If you do not have a timer currently you would need the T10604R which is a 220v on/off timer and a high/low timer.

How can I tell whether or not my motor is a dual or single speed?
Reply
Most dual speed motors will have a toggle switch that will allow you to adjust the motor speed to either high or low. Another way to tell if your motor is dual speed is by looking at the RPM's on the motor specifications label. If there are two RPM's listed such as: 1725/3450 then motor is dual speed. If there is only one RPM, then motor is single speed.

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 have a 1.5 hp Sta-Rite Duraglas H/L spa pump that a motor repair specialist deemed to old to rebuild. I think the H/L stands for high/low as it is a two speed. This is an AO Smith motor with what I believe is a model number P2R-A5YF 125. Is the one listed the pump I need to replace my old one? Will the impeller, difuser etc. attach to it?
Thanks for your help, hope to place an order with you if I can match a replacement.

Good morning Harley, If the hp on your pump is the original 1.5hp you will need a A.O. Smith 1 1/2 H.P Square Flange Up Rate Motor - USQ1152 You will also need to replace the shaft seal and possibly the o-rings (seal plate and diffuser). You can get all of those in a Tune Up Kit Sta Rite Dura Glas & Max E Glas Pump 1998 To Present - GOKIT54

I am sure this motor is the right replacement for my Hayward pump. But all the labels on the pump are too faded to read. But the motor label is identical. All that is on the pump is "Hayward".
