I am replacing an AO Smith C48K2EC11C3 1 HP motor on an irrigation well pump; the replacement listed for this motor is an SQ 1072 which is listed at .75HP. Isn't there a 1 HP replacement motor? What modifications would have to be made to the coupling assembly to mate to the present Sta Rite pump model SNE-L?

A  Answered on 7/14/2019 by InyoPools Product Specialist Lennox H.

Hi, Jerry. You can use the USQ1102 motor instead of this SQ1072 motor. No modifications will need to be made, you will need to replace the Pump Shaft Seal - U109-6A

I have ordered a new AO Smith electric motor and it looks like it comes with a water slinger already attached. Is that true or do I need two add a water slinger to the new motor? Thanks.

A  Answered on 6/19/2019 by InyoPools Product Specialist Steve M.

Don, that is correct the Century Motors A.O. Smith 3/4 HP Square Flange 48Y Full Rate Motor - SQ1072 does come with the water slinger already attached. 

?     Asked on 5/31/2019 by Linda Jarvis

is the impeller a separate piece I need to order or can I use the one from the old motor?

A  Answered on 5/31/2019 by InyoPools Product Specialist Hector F.

If the impeller is in good condition with no breaks, or significant wear and is the correct one for your pump and motor then you do not need to replace it.

When I try to turn on the pump for my pool the motor just makes a humming noise, is the motor bad or do I need to replace the whole pump? The motor is a SQ1072

A  Answered on 5/25/2019 by InyoPools Product Specialist Lennox H.

Hi, Jacob. The issue could be a bad capacitor or a bad motor. You can use the A.O. Smith Troubleshooting Guide to diagnose the issue.

I replaced my SQ1072 motor about 2 years ago. Now it is making a loud noise and I noticed the pump (PE 5D-1241) is leaking into the motor and on the ground. I plan on replacing the motor again but what can I do about the pump? Is there a rebuild kit for it thats not too complicated to do. I remember buying seals last time but didnt use most because I didnt know where they went. Is there a video for this? Any help would be greatly appreciated.


A  Answered on 1/4/2019 by InyoPools Product Specialist Patrick P.

Hi Jane, If your pump is pre-1998 then you will require the Go-Kit-6 StaRite Pump Tune Up Kit and if your pump is from 1998 or newer then you will need the StaRite Go-Kit-54 Tune Up Kit. If you are unsure of the date of your pump then you can watch this Video on How to determine if your Sta Rite Pump is before or After 1998 which should help.

I currently have a 3/4 hp. motor, and didn't know if there would be any advantage to getting a 1 hp motor?

A  Answered on 9/1/2018 by InyoPools Product Specialist Lennox H.

Hi, Brian. There will be no advantage to going to a higher horsepower motor.

Will this motor replace the motor in a hayward booster pump model 6060??

A  Answered on 4/25/2018 by InyoPools Product Specialist Kevin G.

Hello, no the SQ1072 will not work as a replacement for the original 3260-108 that is on the pump.

I have a starite Dura glass /Max e glass pump . what shaft seal do i need to use?

A  Answered on 11/2/2017 by InyoPools Product Specialist Lennox H.

Hi. You the replacement pump seals are listed on the Sta-Rite Dura-Glas and Max-E-Glas Parts Diagram page. There is a Pre-1998 and a Post-1998 option.

Is SQ1072 energy efficient motor? How does it differ from QC1072 motor and what are the benefits of using one versus another? Both will fit my pump. Thank you.

A  Answered on 10/20/2017 by InyoPools Product Specialist Hector F.

The SQ1072 is not an energy efficient motor and the QC1072 is. It draws less amperage hence giving you slightly less of an electrical expense.

Hi I am looking to replace the motor on my Sta-rite pump. Would this motor work? If not which one would I need? Pump model #: P2ra5d- 180L Motor# C48J2PA105C1

A  Answered on 8/5/2017 by InyoPools Product Specialist Alex V.

Matt, Based on the pump model, the replacement motor would be the USQ1072. I would also recommend replacing the shaft seal when you replace the motor. We have a parts list for your pool pump here. There are 2 different shaft seals depending on the age of your pump.

Will the SQ1072 replace a A.O. Smith C48D62A04 on a Hayward 6060 Booster pump? 48Y, 3/4 HP full rated, 1.67sf

A  Answered on 12/27/2016 by InyoPools Product Specialist Andy O.

Hello Mark- Yes you can use the A.O. Smith 3/4 HP Square Flange Full Rate Motor SQ1072. I also recommend purchasing the shaft seal when replacing the motor which is a HAYWARD SHAFT SEAL (OEM) - SPX2700SA.

I have this pump on a filter for an inground pool. It is old, 15 years or so. It seems to lose power after a short time. Can I upgrade to the 1hp? also will just a new motor give me the power back that I am looking for?

A  Answered on 5/22/2016 by InyoPools Product Specialist Patrick P.

Hi Scott, You can upgrade to a larger HP but you will also need to replace your impeller with a 1 HP impeller and this should give you more flow. One other point to consider is that you want to make sure that your filter can handle the increased output of the pump. There should be a label on your filter shows the maximum flow rating the filter can handle.

How many gallons per minut or per hour does this one pump?

A  Answered on 7/12/2015 by InyoPools Product Specialist Alex V.

Hello, The motor is not rated in terms of gpm. The gpm is dependent on the pump housing not the motor.

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.

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.
