?     Asked on 8/1/2017 by Marty Hopper

I currently have a Century ST 1202 Model Num. K48N2N106C1 motor that runs an irrigation pump. I had one that lasted 10 years then the next one lasted 2 years. the one I have now burned the winding's in 3 weeks. Is there a more heavy duty motor I can upgrade to?

A     Answered on 8/2/2017 by InyoPools Product Specialist Alex V.

Marty, Based on the specs of the ST1202, the comparable motors will not be as "heavy duty" as what you have now. I would recommend staying with the ST1202.

I have a K48N2N104. I am looking at your site: http://www.inyopools.com/Products/00200017001213.htm?Keywords=k48n2n104 I would like to buy a motor with a bit more power 2.5hp. Do you recommend this? Which model would recommend?

A     Answered on 7/16/2017 by InyoPools Product Specialist Lennox H.

Hi, Hoss. The K48N2N104 motor has a total hp of 2.6 hp so if you're looking to step up the motor you'll need the ST1302 motor.

Hi, I have a Century Centurion 2 hp, 230v motor, The pump is an American Products Co. Model #38298. The motor still runs good but the impeller that is bolted to the motor is making a very loud noise. I would like to get a new motor and impeller/pump. What can I replace that with? Thanks, Doug

A     Answered on 5/15/2017 by InyoPools Product Specialist Lennox H.

Hi, Doug. They are different 2 HP motors available and I was not able to locate an American Products pump using that model number. Please send us pictures of the motor label and of the pump housing so that we can try to identify the replacement motor and pump.

I have a motor that went out and I'm trying to find the correct replacement. Your help would be appreciated. My pool has a Jandy pump model# JHP2.0, Serial # 0834. Can you point me to the correct motor? Your assistance is greatly appreciated.

A     Answered on 3/28/2017 by InyoPools Product Specialist Andy O.

Hello Jennifer- The correct replacement motor for your JHP2.0 is the Motor 56j Thrd Full 2 Hp - B836.

My old AO Smith pool motor burned out model # K48M2N110 at 1.5 HP, can I replace upgrade to the ST1202, 2HP unit? And if so, is this the correct impeller to upgrade to? Sp3021-c

A     Answered on 2/13/2017 by InyoPools Product Specialist Scott W.

If your current pump is a Hayward Super 2 then yes, that is the correct impeller to upgrade with the ST1202. That is fine to do that as long as your filter is able to handle the increased flow rate.

I have two ST1202 pumps, both are models K48N2N, HP, 56J, 1.33, etc, except one is 11.2 Amp, and the other is 12.6-11.4 amp. Question 1: my 11.2A pump is leaking very small of water at the hump on top of the pump, and it shuts off itself every hour or so. Do I need to replace the motor or just a seal somewhere? Question 2: if I need to replace, would the 12.6-11.4 amp model work? Thanks

A     Answered on 9/13/2016 by InyoPools Product Specialist Lennox H.

Hi Josh, Yes, I would recommend that you replace the motor and the seal within the pump and the ST1202 Motor with the Max Load Amps of 12.6-11.4 will work.

I have a super II Hayward 2 hp pool pump. Motor Model # C48M2N111A3 "smith motor". Sounds like the bearing are going out, can you tell me the replacement motor I would need? This is the 3rd time I have replaced it in 8 years of owning the pool. Thank you

A     Answered on 5/2/2016 by InyoPools Product Specialist Lennox H.

Hi Gary, This motor (ST1202) will be the correct replacement for the C48M2N111A3. I would also recommend getting the Hayward Super II Pump Tune Up Kit GOKIT2 or GOKIT2SALT.

I am ordering a ST1202 pump, and would like to order a new impeller as well. What is the model number for the appropriate impeller? Is there any way to get them shipped assembled?

A     Answered on 1/15/2016 by InyoPools Product Specialist Andy O.

Al-  The ST1202 motor will fit on several different pumps, in order to find the correct impeller for your pump we would need the model of the pump. And unfortunately, they will not come assembled.

?     Asked on 12/29/2015 by Terry

Is there any advantage to upgrading from a ST 1202 to a ST 1252? And if so, do you have to change the impeller?

A     Answered on 12/30/2015 by InyoPools Product Specialist Hector F.

The ST1202 and UST1252 have the same total hp so you would not need to replace the impeller. There is no real advantage in changing the model.

?     Asked on 9/21/2015 by Blaine

Which bearing fits this motor?

A     Answered on 9/21/2015 by InyoPools Product Specialist Matt S.

I purchased and received the motor above to replace a very loud motor with the description as follows:. A.O. Smith, type :cx , Frame: Y56J, HP:1.5, SF 1.0, Volts: 230/115, Code: E, model: 0-184982-23 Is not installed. Will it fit and work ok?

A     Answered on 2/3/2015 by InyoPools Product Specialist Robert M.

Hello Larry - The motor would fit. However, you would need to upgrade the impeller and possibly the diffuser. These parts would depend on the make and model of your pump.

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?

A     Answered on 1/19/2012 by InyoPools Product Specialist Patrick P.

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.

Why should I purchase a Tune Up Kit?

A     Answered on 1/12/2012 by InyoPools 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.

?     Asked on 1/12/2012 by Guest

Why do I need to purchase a new shaft seal?

A     Answered on 1/12/2012 by InyoPools 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.

What is Service Factor?

A     Answered on 1/11/2012 by InyoPools 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.
