Product Description




PureLine 3/4 HP Replacement Pool Motor for Hayward & Jacuzzi Pumps

Is your pool pump motor running loud, leaking or humming? These are all signs that it’s time to be replaced. The PL1072 PureLine Replacement motor is designed as a drop-in replacement motor for some of the most popular 3/4 HP pool pumps like the Hayward Super Pump, Hayward Super II, Hayward Max-Flo, Jacuzzi Magnum and many more.

The PureLine replacement motor is made of the highest quality components like sealed ball bearings which means it is an ultra quiet motor. Because of its high-quality construction the PureLine replacement motor is backed by a full 1-year warranty.

When it comes to replacing your motor Inyo has you covered we have created a ton of resources to make this project a snap, like our Video on How to Replace a Pool Motor this video walks you through all the steps to replace your motor. Most of our customers decide to tackle this project on their own and by following our video they complete this project in about an hour.

When replacing your motor we highly recommend a tune up kit which includes all the seals and gaskets for your pump.

will this PL1072 replace a Century ST1072? and can you recommend a seal kit model #?

A  Answered on 9/14/2019 by InyoPools Product Specialist Lennox H.

Hi, Michael. Unfortunately, it will NOT. You can use the PL1102 or the ST1072. I will need to know the model of the pump housing in order to determine which kit can be used or use our Replacing Parts For A Pump You Don't Have A Model Number For ... Blog.

I have a century ust1072 3/4 hp 56j motor i need replaced but mine has the square flange do you carty a replacement all i see is round flange

A  Answered on 9/1/2019 by InyoPools Product Specialist Lennox H.

Hi, Zak. The motor flange is different from the pump mounting flange. This PL1072 motor is the correct replacement for the UST1072 motor.

Hi, is this PL1072 compatible replacement for my current motor in the picture. thanks!


A  Answered on 8/26/2019 by InyoPools Product Specialist Lennox H.

Hi, Bruce. Yes, you can use this PL1072 motor as a replacement.

Does this motor replace the AO Smith T1072 motor?

A  Answered on 8/7/2019 by InyoPools Product Specialist Lennox H.

Hi, David. Unfortunately, it will NOT, the ST1072 will.

I need a new pool pump motor. My current one is a Hayward Northstar Pump, self-priming. Please see attached photo and let me know what your suggested replacement part(s) are. Thank you


A  Answered on 7/16/2019 by InyoPools Product Specialist Hector F.

Your replacement motor is the model SN1072 and we recommend replacing the seals and gaskets as well. There are two Northstar series of pool pumps. The older generation and the most recent generation. One way that you can tell the difference is by looking at the design of the union connectors.

c48j2n131b1 need motor replacement and seal kit

A  Answered on 6/7/2019 by InyoPools Product Specialist Patrick P.

Yes this PL1072 3/4 HP Replacement Motor is the correct motor for the c48j2n131b1. We do always suggest a Seal Kit when replacing a motor. To determine the proper seal kit we will need to know your pump make and model information, common pump names would be Hayward Super Pump, ayward Super II, Jandy Stealth, etc.. To supply this information click the reply link below, also if you could send a few photos those are always helpful as well. If you send photos then take a close up shot of the motor label as well as a wide shot of the complete pump to include the pipes going in and out of the pump. To supply photos simply click the reply link below and upload your photos. Once we get any of this information we can make the proper recommendation.

?     Asked on 6/5/2019 by Charles

I'd like to order the replacement motor and gasket that you mentioned (part no?). My motor has this pictured attachment on the business end. It seems only held on by two plastic strips. Should that be replaced too?


A  Answered on 6/5/2019 by InyoPools Product Specialist Patrick P.

Hi Charles, your photo shows a part # on your impeller of SP2610C so you have a 1.5 HP Pump and will require a UST1152 1.5 HP Replacement Motor. Your impeller looks damaged so you will need the SP2610C Impeller and a Qty. 4 Motor Mounting Plate Screws to replace the zip ties. You will need this Super Pump Seal Kit I don't think you motor mounting plate needs to be replaced, you just need the proper screws. If you do want to downsize your HP from 1.5 to 3/4 HP then you can use the PL1072 3/4 HP Motor on this page and use this 3/4 HP Super Pump Impeller. You would still use the same screws and tune up kit as mentioned earlier in this reply.

A  Answered on 4/7/2019 by InyoPools Product Specialist Lennox H.

Hi, Chris. The PL1102 motor and the Jacuzzi Magnum Pump Tune Up Kit - GOKIT14 are the parts you will need to get your pump running again. 

?     Asked on 4/5/2019 by Bob

I am trying to replace the motor on our Hayward super pump assembly. Currently has the Century UST1072, RPM 3450, FR 56J,MOD C48J2N131C1C. Will the PL1072 be compatible? I think my main concern is the C flange which has the threaded flanges for mounting to the assembly.

A  Answered on 4/5/2019 by InyoPools Product Specialist Lennox H.

Hi, Bob. Yes, this PL1072 motor can be used as a replacement. You will also need to get the Super Pump Tune Up Kit - GOKIT3 or GOKIT3SALT

I am ordering a PL1022 The serial # is not there anymore on pump housing. SP 1600 D is in the strainer lid. Is Go kit 3 the right kit?

A  Answered on 3/25/2019 by InyoPools Product Specialist Lennox H.

Hi, Km. Yes, GOKIT3 or GOKIT3SALT is the correct tune up kit for your model pump. 

?     Asked on 3/24/2019 by Jodi

According to the paragraph under "details" a tune up kit consists of "seals and gaskets" THAT IS WHAT I AM ASKING..WHAT PART NUMBERS. Has nothing to do with the flange.

A  Answered on 3/27/2019 by InyoPools Product Specialist Patrick P.

Hi Jodi, This motor can be used on about 10 different pumps and the tune kit is tied to the pump. Could you let us know your pump name? Common names would be Hayward Super Pump, Hayward Super II, Hayward Max Flo, Jacuzzi Magnum, etc.. Or if you want to take a photo of your pump then we could suggest the proper tune up kit.

?     Asked on 3/23/2019 by Jodi

Which tune up kit is needed for the PL1072?

A  Answered on 3/23/2019 by InyoPools Product Specialist Lennox H.

Hi, Jodi. Tune up kits are not identified using the motor, they're identified using the pump housing model or name.

  • Commented on 3/23/2019 by Product Owner

    So again. If I am ordering the PL1072 then what else is needed. The site recommends a "tune up kit" but there are multiple to choose from.

    • Commented on 3/23/2019 by InyoPools Product Specialist Lennox H.

      Jodi. Please provide the model number or a picture of the pump housing, NOT the motor so we can identify which pump tune up kit you will need. You can also use our How to find the Correct Pump Tune up Kit guide for more info.

I'm looking to replace a Hayward spx1605z1m / c48j2n131b1 motor (hums, won't come on) amps are 11.0/5.5, on a pump that is only 2.5 years old. This PL1072 is indicated as a replacement, but amps are a bit higher. Is that any issue? Also looked at the UST1072 Century a bit higher cost. I'm just confused at this point as to which one is best to purchase. Help? Thanks

A  Answered on 7/16/2018 by InyoPools Product Specialist Lennox H.

Hi, Kathryn. This PL1072 has a lower purchase price but will the higher amp will cost more to operate. The UST1072 has a higher purchase price but will cost less to operate. Either option can be used as a replacement.

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.

?     Asked on 1/18/2012 by Guest

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.

A  Answered on 1/18/2012 by InyoPools 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.

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.
