I have a OptiFlo high performance pump. It's 1.5 HP spl. Serial # 0360257 1201398 and model # 193262. What would be the correct replacement motor? Thanks for your help.

A     Answered on 9/20/2017 by InyoPools Product Specialist Lennox H.

Hi, Bob. The Century 1 H.P 115V Thru Bolt Motor - BN25 is the correct replacement for model #193262.

Hi, Paola. This motor can be used to operate selected Flo-Master XP2 pumps models. I can not confirm without the pump model or the motor's part or cat number.

Looking for motor bearings for the BN50 and can't seem to find them described anywhere in a parts reference.

A     Answered on 5/23/2017 by InyoPools Product Specialist Stacey M.

Hello Gary, I apologize, but we don't have any listed for that type motor.

?     Asked on 11/1/2016 by tom n

is it possible that the seal on the motor goes bad and I just have to buy a motor ? the pump is apart from the motor right?

A     Answered on 11/1/2016 by InyoPools Product Specialist Scott W.

If you are replacing the motor you will also need to replace the shaft seal. I can help you with that, I just need the model of your pump. If you do not know attach a picture of your complete pump and I will identify it for you.

?     Asked on 9/26/2016 by half hand

can this motor's speed be varied or are the rpms fixed?

A     Answered on 9/26/2016 by InyoPools Product Specialist Stacey M.

Hello, normally on a single speed motor the RPM is 3450, but for a duel it's 3450/1725. This BN50 is a duel speed motor which has 1.5hp or .25hp.

?     Asked on 9/13/2016 by Robin

We have an AO Smuth spa motor and are looking into buying parts to fix a leak, or possibly replacing the entire motor. Current part#: 7-177803-02, FR: U48Y, Type: CDM, PH: 1, CAT: BN50, Volts: 115. Would this be the correct replacement motor? Also, are there any replacement parts available for the pump we currently have?

A     Answered on 9/14/2016 by InyoPools Product Specialist Scott W.

The BN50 is the correct replacement motor. For me to find the correct seals and gasket for your pump, I'll need to know what model your pump is that the motor goes to.

Is the BN50V1 the replacement pump for A>O> Smith century lasar 101458

A     Answered on 8/12/2016 by InyoPools Product Specialist Lennox H.

Hi Kay, I was not able to cross reference the info provided to the BN50V1 motor. If you can provide additional info like the pump model, CAT, PART or MOD number I can confirm if it is.

I am getting a1 1/2 HP 2 Speed 115V Thru Bolt Motor (External Capacitor) - BN50 motor to replace a bad motor in my spa. (this is supposed to replace the bad motor: Emerson T55MWBLJ motor). The pump attached to the end of the motor is: 6500-345. Can you tell me which "tuneup" o-ring seal kit to get for this pump? Thanks, Bob

A     Answered on 7/14/2016 by InyoPools Product Specialist Lennox H.

Hi Bob, We do not have a tune up kit available for the 6500-345 model pump but the Jacuzzi Shaft Seal 200 3/4" (10150209) and Cover Gasket (47025853) are the parts needed. If you need any other parts they can be found on the Jacuzzi Piranha Series Pump Parts page.

I'm looking to replace my motor for my waterway pump. I have a A.O. Smith motor HP 1.5 - .18 SPL, MODEL # PH2150-3R, CAT # BN37, PART # 7-177782-03, FR R48Y, VOLTS 115, AMPS 11.0/2.9, TWIST LOCK CORD

A     Answered on 7/3/2016 by InyoPools Product Specialist Lennox H.

Hi Jeff, The BN37 motor is the correct motor for the PH2150-3R pump. The "SPL" does not reference the actual hp of the pump.

I am looking for a 50 cycle motor for my 1.5 hp Pentair Opti Flow pump.

A     Answered on 4/11/2016 by InyoPools Product Specialist Alan M.

Hello Andrea, I found the Pentair Optiflo Pump - 3/4 to 1 1/2 HP Parts breakdown. In the motor section (#15) the single speed replacement for your pump is the 1.5 H.P 230/115V Thru Bolt Motor (BN35). I was not able to find reference to any additional 50 cycle motor. (There is also a 1 1/2 HP 2 Speed 115V Thru Bolt Motor available as well part #BN50)

Hi, I have a Magnatek 7-177803-02 pool/spa motor , 2 speed, 115 v, 16.4/4.4 amps that has a broken toggle switch. Can you furnish part number, price and availability? Thanks T Nonan

A     Answered on 7/16/2015 by InyoPools Product Specialist Lennox H.

Hi, We will have to know what model or p/n of the 2 Speed Toggle Switch that you have operating that motor. If you're not sure you can replace the entire cover with the 2 Speed Toggle Switch (18313301).

?     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.

?     Asked on 5/16/2007 by Guest

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.
