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.

Hello Ralph - The correct replacement motor is model SQ1302. We would also recommend replacing the seals when you replace the motor. The seal kit for regular water is GOKIT32 and the kit for saltwater is GOKIT32SALT.

Yes we would suggest replacing your motor and you would require the Hayward 2 HP Full Rate Replacement Motor. You will also need a shaft seal and the northstar pump has used two shaft seals of the years which I have listed here... Hayward Northstar Shaft Seal 1998 - 2007 or Hayward Northstar Shaft Seal 2008 - Present.

I have a whisperflo 2 hp motor that just went bad. I have a spa attached to my pool and was thinking of upgrading to a 3 hp. Would I need a different impeller or would i be good with just the motor swap?
Thanks

Marion - When you go to a 3 HP EE motor (B844), you will also have to upgrade the impeller to 5074-27E and the diffuser to 5074-13. We also recommend that you replace the seal and gaskets with GOKIT32 or GOKIT32SALT. If you choose not to replace all the gaskets, you will have to change the shaft seal as a minimum. See key # 16 in this Whisperflo parts list. Thereare three options OEM, Generic and Saltwater pools

The go kit that you will need to use is based on the model of the front plastic pump housing that the motor is mounted to. Any other parts needed will be based on the condition of them once the pump is taken apart and inspected.

Hello,
Have a Magnatek 177453-03 pool motor, this morning it did not start and the breaker was flipped. I flipped the breaker back on and it trigger off again. I remove the motor and check for any wire to wire contact in the conduit, removed the motor back cover to see if there was any obvious problem, burned stain or odor but everything looked ok, then I did a test run, for a second it sounded like if it was going to start but the breaker trigger again.
Any suggestions?

Currently have a Century Centurion B2844. Sound like the motor is going out as it's becoming noisier. I'm just wanting to place the pump but my wife is dead set on replacing it with a variable speed. What would I need to do to keep her off my back (ie, what model of variable speed pump and whatever else I'll need)? Also, our pool is pretty small using your formula around 4,000 gallons.
Reply
Hi, Happy. You have a large pump for such a small pool. We do not have a replacement variable speed motor that would replace the B2844 motor. You would have to replace the entire pump with the EcoStar - SP3400VSP or Intelliflo - 011018 if you need such a large pump. I would recommend calculating the feet of head of your pool using the steps in our How To Size a Pool Pump and How Do I Calculate Feet of Head for My Pool? to make sure the pump you have is not oversized.

The grey pipe is for the electrical, on all of our motors you are able to connect that grey pipe to cover your wiring that goes from your pump to your breaker.

Hi, Paul. You can upgrade to a 3 hp motor reusing your existing impeller and diffuser. However, if you want to increase water flow, you will have to change your impeller and diffuser after confirming if your filter, plumbing, and system is sufficient. To determine that you will have to calculate the Total Dynamic Head (TDH) of your pool, then use the pump performance curve to determine the flow.

Hi. I have a Pentair WhisperFlo with B7248 2HP standard efficiency motor. It’s a 1Ok gallon pool with 2” piping. Can I upgrade to the AO Smith 3 HP high efficiency?? Thank you..
Reply
Hi Derek, It is possible to replace your motor with a 3 HP and replace the impeller and diffuser to 3 HP but you may have issues with going with such a large ,pump. Normally for a 10,000-gallon pool you could use a 3/4 or 1 HP pump. Some of the issues with going with a pump this large are... 2" pipe can only accommodate 120 GPM and the 3 HP will exceed 120 GPM so you will not be getting the full capacity of this pump with using 2" pipe, the 3 HP is expensive to operate, finally you need to make sure your filter can handle the output of the pump which would be in the 120-150 GPM Range. You should have a label on the side of your filter which says max GPM. If you decide this is the route you want to go let us know and we can give you the part #'s for the impeller and diffuser.
Reply
I’m not sure which model is mine. The sticker is weathered. Gpm should be good for 3HP? How much more expensive would 3HP high efficiency be compared to 2 HP standard efficiency? Thank you..
Hi Derek, The price of the 2 HP B2748 Replacement Motor is $272 Where this 3 HP motor is $339 also on the 3 HP you will roughly another $100 in parts to upgrade to 3 HP as you need to replace your impeller and diffuser if you go up in HP.
