Hello, I can look into this for you. Can you please provide a picture of your current motor label?

I have a S48L2440B1, thats getting hot and throwing the thermal breaker in the motor. Its on a sta-rite JWPA55YD-A2.
Two speed .75-.16 hp used for pond filtration. Is the same motor available ? and do you supply?

I have an Emerson SA55NXHZW-4788 motor that is locked up. Is this pump the correct replacement? I have attached a photo of the data plate.
Hi, Anthony. Based on the info on the label provided, some of the specs matches, however, I do not see a Frame (FR) size or if it's for use for pool/spa duty on the label. Please provide a picture of what this motor is used for.

I have a waterway Hi-Flo 3/4 HP side discharge, 2-speed pump. It has this motor on it 7-177781-02 AO Smith.
The pump itself is fine. When I went to start up this spring, the motor would only work on low speed. I flipped the switch back and forth, and a few minutes later (motor still staying on low) it stopped. The motor smelled burnt, and smoke came out of the side of the motor.
I plan to replace it with this motor. Should I replace the pump / motor seal? if so what would the part be?
Reply
Hi Jeff, Based on the model # you supplied this motor is the correct replacement motor for your pump. Yes, we definitely suggest replacing the shaft seal and you will require this Waterway Hi-Flo Shaft Seal.

I have a Speck Model E-71 pump (ProLine-branded, current motor PE71-II-H) and I want to downsize it to 3/4 HP because the motor is obviously oversized for my 15k gallon pool and 75 GPM filter. Will this motor fit? I will need the shaft seal Mechanical Seal 5/8" - 2921606204 and Impeller, E-75-i, 3/4 Hp (2921923096)? I can do the 2-speed wiring. Thanks!
Thank you for your prompt reply. How can I tell if the impeller has not seized? Is there anything else I should check before replacing the motor? Also, if I were to replace the entire 355 pump, what would be a viable replacement. Thank you.
Reply
Hi, Rose. You can manually turn the motor shaft to see if it turns freely. It if does not then the motor is seized. You can use the FMHP Pump - 02107000-1010 as an alternate replacement.

We're using our 355 pool/spa pump for a garden pond and waterfall. It has done the job well. This spring, the pump would not turn on. It is also the first time we left it outside for the winter. I'm debating between purchasing a new pump or replacing the motor. My pump motor part number says - 7-177781-01. Will your 7-177781-02 work with it? Also what does 1081/1563 pump duty mean? Do you think it is worth replacing the motor or could something else be wrong? Thanks for your help.
Reply
Hi Rose, I would suggest just replacing the motor as this really the only thing that goes wrong on the pumps. Yes the 7-177781-02 will replace your 7-177781-01 motor. 1081 mean that the motor is listed to the UL1081 safety standards for pool pump motors.

Hi, We just got a used MagneTek Pool pump filter system for our 24' above ground pool. All of our pool stuff burned a barn fire, and I'm trying to figure out what I need to use the MagneTek filter. What size hoses, etc. I can't find much info on this system (we had a Hayward before). Any help you can give is appreciated!

Hello,
I have a part # 7-177781-02 serial number 026093M. The motor has a high pitch squeal, I believe the bearing need to be replaced.

Our hot tub is leaking where the pump attaches to the motor, It is a 1 1/2 inch on center discharge pump and It appears to me to be one unit but I am not sure. The motor I am replacing is:
Century B036, Part # 7-165361-01, RPM 3450/1725, volts 115, Model 225-728( the 8 may be a 5 or an S), Serial # 391282/L02, HP 3/4. Do you know if this unit is available with a 1 1/2 center discharge pump attached?

Hi, Bill. You can use the Waterway Spa Pump (Center Discharge) - 342041015 as a replacement pump.

Hi guys i sent in a question back in jan. of this year.about my new motor will not go from back to low speed after running on high. you mention the impeller might be getting stuck so i rebuilt the pump with a new housing and seals and it did again not right away but after being running. Is it possible the motor is just have a bad spot in the windings or is my impeller tighten down too much . Is there a amount you tighten the impeller too Please help I dont want to go all summer this way
Reply
Hi. It is possible that the motor is bad causing the motor not to go from high to low speed and vice versa. The impeller should be hand tighten onto the motor shaft and should spin freely with little to no resistance.
Reply
I bought this motor last summer to replace the one on my system, It worked great for around two months then it started to to get 'get stuck" when switching to the second speed. If I spun the shaft less than a quarter turn it would work. It finally got to the point where it doesnt do that . It is a hayward system for a hot tub can you tell what is wrong I drained the hot tub before fall and right now the unit is in my basement
Reply
Good morning Terry, It sounds like the impeller is getting stuck/ jammed.

I have a Waterway HiFlo single speed pump BN25 can I us this pump as a substitute? I would like to go to a 2 speed pump the dimensions are very close to each other. RPM on the BN25 is 3450 the BN36 has RPMs of 3450/1725. Will this pump work or can you suggest another pump motor? Thanks.
Reply
The BN36 would fit your Hi-Flo but going from a 1HP to a 3/4HP you would have to change the impeller as well to fit the horsepower.

When I plug in the pump, the motor starts going very slow and then stops. I replaced the capacitor and it still does the same think. The dealer where I bought the new capacitor told me it was a run type. Is there another somewhere inside the motor?
Reply
Hi Paul, Some motors have a run capacitor and a start capacitor however this BN36 motor only has a run capacitor. If you have a different motor then the BN36 let us know and we can determine if your motor has a start capacitor.

I'm trying to find a replacement motor for my pool pump but my model number doesn't match what you have listed as the model number. My model number begins with a C48 and yours begins with an SP. Please help.
Reply
What we have listed on our chart pages is the pump model number. The model number you have will just identify the motor. If you look on the plastic housing on the pump there should be a sticker which will have the pump model number. You can usually find this by the discharge port on the pump. Once you locate it you can choose the correct replacement motor. Be certain to change the shaft seal and gaskets as needed. You can use our >How to guide if you need help.

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.

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.

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.

Can you replace single speed pump motor with dual speed pump motor?
Reply
Yes but you can't go with a higher HP than the single speed motor. For example if you have a 1 HP single speed you cannot go with a 1.5 HP dual speed motor; you would be able to use a 1 HP dual speed motor. Customer would need to purchase a toggle switch or timer to switch from high speed to low speed.
