I have an in ground pool that was salt, the circuit board went bad. I am replacing the UST 1102 motor, should I use the salt water seal kit. I am planning on replacing the salt control, to put it back to salt water.
 Reply

A  Answered on 9/12/2019 by InyoPools Product Specialist Hector F.

Yes, I would suggest using a saltwater seal as it may help protect the new motor better. You will just need to know the model name or number of the front pump housing that the motor attaches to in order to cross-reference the correct seal or seals. If you are not sure of that model please send us images to upload@inyopools.com so a tech can review and further advise.

Hi, My UST1102 pump started making a high pitch noise and shut off, so probably time for a replacement. Based on the pics, can you confirm this is the right replacement, and provide a recommendation for energy efficient and variable speed options? Do you have a recommendation between energy efficient and variable speed? I don't really see what makes the 'energy efficient' version energy efficient. Thanks!

 Reply

A  Answered on 8/18/2019 by InyoPools Product Specialist Lennox H.

Hi, Justin. This UST1102 is the correct replacement. Your other option is either the UCT1102 which is the single speed energy efficient option. The UST1102 is uses 7.5/15 amps at 230/115 volts, the UCT1102 motor uses 5.5/11 amps at 230/115 volts. The variable speed option is the ECM16CU. Whichever option you decide to go with, you will also need the Hayward Super Pump Tune Up Kit -  GOKIT3 or GOKIT3SALT.

I have a Jacuzzi Magnum Plus pump system attached to a Landslide filter. Over the last 6 years, I have had to replace two UST1102 motors for this system. The motors seem to run hot- I cannot touch the motor casing due to the heat buildup after being on for a short time- and so, the motors do not seem to last long and need replacement. Would the ST1102 be better motor for reducing the heat. or should I stick with the UST1102?
 Reply

This is NOT the proper replacement motor for the motor in your photograph. You will require the B128 1 HP Replacement Motor 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 Pentair Whisperflo, Pentair Challenger, 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.

I currently have a Hayward housing that has a replacement motor (UST1102 , 115/230v ; HP 1 ; RPM 3450) and it's dead. 11k Gallon Pool has a spa waterfall spill into the pool & Hayward Navigator suction robot, Jandy TruClear SWG, & Steener tank & muriatic acid pump. Could just replace the current SS w/ VS 1-for-1 or would I need the VS motor, automation, and other things to make it all work together?

Hi Harry, You could replace your UST1102 motor with this PL1116 1.5 HP Variable Speed Motor this motor comes with the controller mounted to the top of the motor, so nothing else is needed to control the motor. You would also need this Hayward Super II Seal Kit when you replace your motor.

The UST1102 can replace the B228SE, but it will be more expensive to operate. The B228SE is the Super Efficient 1 HP uprated model, and only uses 12 amps; whereas the standard UST1102 uses 15 amps.

I am trying to replace a AO Smith C48J2N131B3 Super II pump 3/4hp running at 115 v for a SP3005X7AZ Haywood pump. Will this 1 hp motor work and is there any benefit to the hp increase? Also what seal kit do you recommend.

Hi, J Carter. You can use this UST1102 motor as a replacement. There is no benefit to using a larger motor with a smaller impeller. You will need the Hayward Super II Pump Tune Up Kit GOKIT2 or GOKIT2SALT for that model pump.

If it was, you will have to purchase the matching impeller and seals if you want to go to a higher horse power motor.

I bought the A.O. Smith 1 HP Round Flange Up Rate Motor and replaced my old 1hp motor that had burned out. While the system is running, the water pressure is lower than before. The heat pump is not able to operate due to low pressure and the return pressure is definitely lower than it used to be. The filter is at 9 PSI though which is in the normal range. It used to be at 10-11 before. Before reinstalling I did clean the impeller. What could be some reasons for the low pressure?

Keith, If you just replaced the motor, you may have air in the lines. If you have an air relief valve on your filter, you can purge the air manually. Once the air has been purged, you will see an increase in pressure.

buying this as a replacement for a sp1607z1m. is this the correct replacement? it says this model in the alternate part #s so i'm guessing it is. also which replacement shaft seal works with this motor? it is going on a sp2607x10 pump. thank you.

Hi, Shane. This UST1102 or the PL2228 motor can be used as a replacement. I will also recommend that you get the Super Pump Tune Up Kit - GOKIT3 or GOKIT3SALT.

I am replacing a Hayward super ii 2 hp. It is a dedicated pump for the waterfall. The previous owners installed a ball valve to limit the flow since 2 hp was too much. Will this work as a replacement as that motor no longer works?

Hi, Clay. You can downsize the motor, You will also need to replace the Impeller - SPX3007C, Impeller Ring - SPX3005R, Diffuser - SPX3000BN and get the Super Ii Pump Tune Up Kit - GOKIT2.

What replaces the A.O.Smith st1102 pool pump motor?
 Reply

A  Answered on 4/6/2018 by InyoPools Product Specialist Hector F.

That is the correct replacement motor for the ST1102. It is the ST1102. If you need a complete pump then you would need to locate the model number on the front plastic pump housing that the motor bolts to.

I am replacing the motor on Hayward SP2607X10 Super pump on a Salt Water Pool. I noticed in the forum you recommended this A.O Smith but while shopping in pool parts it recommends the Pureline PL2228. Will either of these work for my replacement. I like the fact that the Pureline has a 2 year Warranty. Which would give me better service in your opinion?.
 Reply

A  Answered on 4/4/2018 by InyoPools Product Specialist Hector F.

If you are replacing the original motor that came with the complete pump then yes, either motor will work. The Pureline is just another option being our line and should work just the same. It carries the same warranty as the A.O. Smith as well.

Salt water making its way past the man shaft seal to the motor face can indeed cause the bearings to fail which is known to create the loud noise.

is there another motor to replace this one that is quieter. thanks
 Reply

A  Answered on 6/9/2017 by InyoPools Product Specialist Hector F.

The two more quiet model motors would be either a dual speed or variable. Those motors in low speeds are far quieter. The dual speed model is the B973T and the variable speed model is the ECM16CU. You just want to get the model name or number of the front pump housing that the motor bolts to making sure that the motor control boxes fit ok.

Yes, the UST1102 is going to be the replacement. UCT1102 is the energy efficient replacement that uses 2 amps less while keeping the same horsepower so saving money on your energy bill. STS1102 is the dual speed replacement that will allow you to run it at high, 1HP, and low, 1/4HP, which has the potential to save you even more money. The real energy saver is going to be the ECM16CU which is the variable speed replacement. With the variable speed you will be able to adjust the RPM's to where it is going to be the most efficient for your system. The seal kit you want is the GOKIT3SALT.

The replacement motor for the K63CXEPY-4766 is the Motor 56j Thrd Full Ee 1hp (b654). The total HP on your current motor is 1.40 and the UST1102 is 1.10. The weight of the impeller, installed on motors will differ depending on the total horsepower. By decreasing the horsepower, the impeller will be to heavy, potentially causing the motor to fail. It is best recommended to replace your motor with the B654, doing so, this will allow you to use your existing impeller. Don't forget to replace the Pool Pump Shaft Seal.

My pool motor finally blew- I have a Hayward Super II pump, MODEL# K48L2N104 , 1 HP, Frame 56J- about to completely disassemble to ensure flange is round- I also have 6 bolts that hold the impeller- is this the correct model to replace my motor with or will I have to also replace the impeller as well- I JUST rebuilt the entire impeller last summer- can't afford to do all over-of course it's an emergency- daughter decided she to have her college grad party Sept 24th!!!!

 Reply

A  Answered on 9/22/2016 by InyoPools Product Specialist Stacey M.

Hello John, you need to make sure you are going with a motor that has the same output that you are getting from your current motor. If you go with a UST1102 your amps are running at 15.0/7.5 SF is 1.1 and HP at 1.1, you are actually going down from the motor your USN1102 motor. Your SF, HP, and AMPs would go down if you went with the UST1102.

If you do move to a 1HP you will have to upgrade to a 1HP impeller. Also, you will want to know the flow rate of your filter. You don't want the increased horsepower to blow your filter.

It's most likely going to be the USQ1102, but to be for sure I'll need to know the model of your Sta Rite pump, not the system 3 filter. If you're not sure you can attach some pictures of the entire pump and I can identify it for you.

When replacing a motor, we would recommend replacing the shaft seal and o-rings on your pump. You will need to identify which pump you have to locate a parts list and the corresponding replacement parts. We would also recommend inspecting your pump to determine if you may need to replace other parts due to damage or deterioration.

I was trying to find the flow rate for the HST110 so I could make sure my replacement was comparable equipment and found that the HST110 is listed as a replacement for UST1102, but still cannot find the GPM flow rate for this pump. Can you tell me the flow rate of the UST1102 or HST110 or suggest a cost effective replacement.
 Reply

A  Answered on 7/20/2016 by InyoPools Product Specialist Scott W.

The flow rate doesn't only depend on the horsepower of the motor but also the impeller for that pump and every pump has a different impeller. But it doesn't stop there, it also depends on resistance or the distance between the pump and main drain. All of these factors come into play with the flow rate.
