I'm looking for a replacement motor for my Hayward super pump 2 self priming 1hp for inground pool. Is this the right one?

Inyo Answer

Answered on 05/14/2015 by Product Specialist Patrick P.

Hi Courtney, If you could double check the service factor (S.F.) on your motor label if it reads 1.1 then this is the correct motor for you. If the S.F. reads 1.5 then you would require The 1 HP Full Rate ST1102 Super II Replacement Motor. When replacing either motor I would suggest a Hayward Super II Tune Up Kit.

Question

Asked on 04/18/2015 by John

I need to replace an A.O. Smith self prime super pump 1/2 HP motor Model s48h2n122b1 in Central America. The motor is overheating and turning off. I am hoping to buy a new motor to bring down. My filter looks like it is rated for 40 GPM, do you have a 1/2 HP motor so I do not have to replace the filter right now?

Inyo Answer

Answered on 04/20/2015 by Product Specialist Patrick P.

Hi John, You would be able to go down to a smaller horserpower which would save you on operational costs. When reducing your motor size you will need to replace the impeller on your Hayward Super Pump. So if you wanted to go down to 1/2 HP you would require the Hayward 1/2 HP Motor and the Hayward 1/2 HP Impeller. We also always suggest the Hayward Super Pump Tune Up kit when replacing a motor.

I have a old Jacuzzi 94027110 and I want to know if this motor will replace the one I have? If so is there any special wiring or anything else that will need to be done or can I just take the old motor off and put this one into the housing and wire it? I would rather not buy a whole new pump unless it is absolutely necessary.

Inyo Answer

Answered on 07/10/2014 by Product Specialist Patrick P.

Yes the UST1102 would be the replacement motor for your 1 HP Jacuzzi Magnum pump and there would be no different wiring required, we would suggest a Jacuzzi Magnum tune up kit when replacing your motor which includes a shaft seal, o-rings, gaskets and lubricant. Typically if you use your old shaft seal it will not mate up properly which will cause leaking.

Question

Asked on 07/10/2014 by Guest

I need to replace the motor on a Hayward Super Pump 3/4 hp. Can I go up to a 1 hp and what difference does that make? If so, does anything else need to be changed out? This is for an inground 16' x 32' pool.

Inyo Answer

Answered on 07/10/2014 by Product Specialist Patrick P.

You could go up to a 1 HP motor which would give you a higher gallon per minute rating (GPM). On a typical pool a 3/4 HP Super pump will have an output of 50 GPM's where a 1 HP will have an output of 65 GPM's. You would want to make sure that your filter could handle this increased flow rating from the 1 HP motor your filter should have a label on it which says max flow rating, this would let you know how many GPM's the filter can handle. If you increased your motor to 1 HP you would need to also replace your impeller to a 1 HP impeller, we would also suggest a Super Pump tune kit.

Will the AO Smith UCT1102 cost less to run than the UST1102?

Yes, the UCT1102 will cost less to operate compared to the standard UST1102. Depending on how the motor is cared for, it should last several years. When replacing the motor, I would recommend buying a tune up kit based on your pump model and age.

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.

Inyo Answer

Answered on 01/18/2012 by Product Specialist Patrick P.

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. 

Question

Asked on 01/12/2012 by Guest

Why should I purchase a Tune Up Kit?

Inyo Answer

Answered on 01/12/2012 by Product Specialist Patrick P.

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.

Question

Asked on 01/12/2012 by Guest

Why do I need to purchase a new shaft seal?

Inyo Answer

Answered on 01/12/2012 by Product Specialist Patrick P.

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.

Question

Asked on 01/11/2012 by Guest

What is Service Factor?

Inyo Answer

Answered on 01/11/2012 by Product Specialist Patrick P.

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.

   (5 out of 5 Stars) Excellent Pump Moter Replacement

Reviewed By: from Clarence, NY ()

Pros: Awesome fit - excellent replacement

Cons: none

Tip to get the impeller off the old pump moter: use a 7/16" open ended wrench - it slides in near the capacitor on the electrical side... rotate the impeller until the wrench slides into place at the end of the shaft and then one person holds the motor and the wrench while a 2nd person loosens the impeller off with bare hands by turning the impeller counter clock-wise.
