Hi. This BN37V1 is the correct replacement.

Hello Dave, I have a BN37 1.5 hp, RPM 3450/1725 AMP 11.0/2.9 part #7-177782.03, Frame R48Y. Apparently this model is discontinued. If possible I would like to g to a 2HP without changing any plumbing. 1 1/2 Inlet and outlet FMCP wertend NEW.

A  Answered on 7/18/2019 by InyoPools Product Specialist Lennox H.

Hi, K. Renee Monroe. The BN37V1 motor is still available. However, a 2 HP pump with 1-1/2" plumbing is not good if your goal is a higher flow.

?     Asked on 6/19/2019 by Dave K.

Re: listed pump. How much is it to include the power cord and and off switch already attached to the motor. OR do you have other like motors that come as a complete system?

A  Answered on 6/21/2019 by InyoPools Product Specialist Lennox H.

Hi, Dave K. Unfortunately, there is not a replacement motor available with a power cord and or switch already attached. These parts will have to be purchased separately and then installed on the motor.

A  Answered on 7/21/2017 by InyoPools Product Specialist Robert M.

Hello Mary - The BN37 will work if you have a thru-bolt style 48Y frame 1HP 2-speed 115v motor. Check the specifications on your current motor to see if these match.

?     Asked on 4/2/2017 by Laura

Need new motor/pump assembly for 24' round 52" pool. Old pump is Waterway, 2HP, 2-speed, Hi Flo SD 1502189245. We always run it on high to move 30 GPM in 8 hours. Low doesn't cut it; barely moves the water. We want our next model to be timer compatible. Looking at Hayward Power Flo Matrix. Need a pump with horizontal fixture. Is 2HP too much? Thinking dual speed, 1.5HP would be better. We got the 2HP our local store had on shelf. What do you recommend? Which timer do we need to match? Thx :)

A  Answered on 4/4/2017 by InyoPools Product Specialist Lennox H.

Hi, Laura. A 2HP pump could be too big depending on the size of your filter.

Hi George, Based on your amp draw you will need this BN50 1.5 HP Dual Speed 115V Replacement Motor I would also suggest replacing your shaft seal when you replace your motor and you would need the Proline PE71 Shaft Seal

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.
