Will this part fit on the Haywood Super Pump, 1Hp 2 Speed, self priming? Can I use the high low switch it has or do I need to purchase a new one?


A  Answered on 6/10/2021 by InyoPools Product Specialist Craig C.

Hello.  The Century Motor 1.0HP Dual Speed motor will NOT fit the Hayward Super Pump.  The Century Motor 1.0HP Round Flange Dual Speed Motor model STS1102RV1 is fully compatible with the Hayward Super Pump.   Without full knowledge of which high/low switch is currently installed, I can not make a recommendation in full confidence.  I would speculate that the switch is compatible.  For a definitive answer, I would suggest consulting a licensed electrician or the motor manufacturer. It is recommended that the motor shaft seal, seal plate gasket, and diffuser O-ring be replaced at the same time.  The GOKIT3 contains the necessary parts to complete this project.   Century 1.0 HP Round Flange 56J Dual Speed Full Rate Motor - STS1102RV1   Tune Up Kit Hayward Super Pump - GOKIT3

I am looking to run this motor as a single speed motor for my pool. Is it possible or do I also need to purchase the two speed end bell.

A  Answered on 9/25/2019 by InyoPools Product Specialist Steve M.

Chris, it is possible to have the Century Motors A.O. Smith 1 H.P Square Flange 48Y Dual Speed Full Rate Motor - SQS1102R only run at one speed. We would suggest contacting the motor manufacturer for advice on exactly how to do this. AO Smith Century Motor Company can be reached by calling 866.887.5216.

is there a 110 volt version of this motor?

A  Answered on 6/19/2019 by InyoPools Product Specialist Matt S.

Unfortunately, this model is only available in a 230-volt.

I replaced the motor on my P6RA6YF-206L with a Century SQS1102R. It works fine on high speed but does not register a flow on low speed and salt chlorine generator gives a steady NO Flow indication and eventually trips breaker. I replaced the flow switch but that didn't help. Filters and skimmers are clean. Any ideas?

A  Answered on 10/2/2019 by Industry Professional

Based on your e-mail we are not clear as to whether the low speed of the motor is coming on or not. If low speed is actually coming on then the issue is with the sensors/flow switch or system itself. If the low speed is not coming on we you need to determine if the motor is getting power to low speed. Have to determine if it is a motor or system issue.

Hi I’m not sure if you received my reply of your message. I’m trying to find out if my pump will run without the impeller screw that I trashed. The pump is a dura/Glas h/l with an AO Smith motor # c48lp104.

A  Answered on 2/27/2019 by InyoPools Product Specialist Lennox H.

Hi, Steve. You can scrap the impeller screw only if you're using a new style motor. 

?     Asked on 2/23/2019by Steve

I didn’t realize that the screw in the impeller was left hand thread. I trashed it getting it out. Can I run without it?

A  Answered on 2/24/2019 by InyoPools Product Specialist Lennox H.

Hi, Steve. You are able to operate some pumps without an impeller screw. You will need to provide the make and model of your pump in order for us to confirm.

    The pump is Dura-Glas H/L with the AO SMITH C48L2P104 motor. I bought the rebuild Kit from you and couldn’t get the screw out in one piece.

      Steve, That model pump is able to operate without an impeller screw.

Good morning, Yes the SQS1102R will fir the FPT20510.

Is the SQS1102R motor a valid replacement for the Flotec FPT20515 pump? The motor model number is K48L2P104B1.

A  Answered on 5/28/2018 by InyoPools Product Specialist Lennox H.

Hi. This SQS1102R is the correct replacement motor for the Flotec FPT20515 pump. You will also need the Tune Up Kit - GOKIT44.

Is the correct two speed motor to use with the pentair challenger CH9II-N1-1 1/2A 1-16-G03 34-6206 with 1 1/2 inch PVC piping?

A  Answered on 7/25/2017 by InyoPools Product Specialist Lennox H.

Hi, James. This Century SQS1102R motor is the correct dual speed motor that can be used with your Challenger Pump. I would also recommend that you get the Challenger Pump Tune Up Kit - GOKIT5.

I am replacing a pump motor, original is STA-BRITE Model P6RA6F-206L Max-E-Pro (also says Model C48L2PA105). 1.5 Hp, 1.1 kW. What would be the correct A.O. Smith motor? Thanks.

A  Answered on 2/20/2017 by InyoPools Product Specialist Lennox H.

Hi, Martin. You can use this motor if you're converting your single speed pump to a dual speed and already have a controller. If you do not have a controller you can use the B2982T Motor w/ Controller. If you want to stick with the original motor you'll need the USQ1152 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.

Can you direct me to the proper hi low switch for this motor?

A  Answered on 1/18/2012 by InyoPools Product Specialist Patrick P.

Unfortunately the manufacturer does not offer the switch for the 2 speed 220v motors any longer. If you already have a 220 volt timer (on/off) you would need an Intermatic T106R to switch from high to low speed. If you do not have a timer currently you would need the T10604R which is a 220v on/off timer and a high/low timer.

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.

Can you replace single speed pump motor with dual speed pump motor?

A  Answered on 5/16/2007 by InyoPools Product Specialist Patrick P.

Yes but you can't go with a higher HP than the single speed motor. For example if you have a 1 HP single speed you cannot go with a 1.5 HP dual speed motor; you would be able to use a 1 HP dual speed motor. Customer would need to purchase a toggle switch or timer to switch from high speed to low speed.
