?     Asked on 2/1/2022by Inyo Visitor

Is this motor a match for the motor I have? Does Pentair make their own motors? Does a 3/4 hp motor come in a variable speed? If so do I need to make adjustments (electrical and otherwise) to accommodate the variable speed? The motor specs for my Pentair Superflo pump are as follows: Pentair 3/4 hp SF HP .94 Motor # 196237 Model # SF-N 1-3/4A/340037 3450 RPM SF 1.27 Thanks!

Hello.  The Century Motors 3/4 HP Full Rate Motor B2847V1 is a compatible replacement for motor #196237.  In most cases, Pentair-labeled motors are manufactured by A. O. Smith/Century Motors.  Currently, there are no 3/4 HP variable speed motors available by any manufacturer (residential pool pump application). The Century Motors V-Green 1.65 HP Motor model ECM16SQU is a compatible variable speed motor.  ECM16SQU   It is recommended that the motor shaft seal, seal plate gasket, and diffuser o-ring be replaced concurrent with the new motor.  The GOKIT78 contains the necessary parts to complete this project.    GOKIT78

?     Asked on 8/17/2021by B2847 Century Motor Replacement or New Pump?

Other than the seal kit what is needed when the motor is replaced? I just added a new sand filter about three months ago now no suction and using a lot of amperage.

 Reply

A  Answered on 8/17/2021 by InyoPools Product Specialist Craig C.

Hello.  Typically a motor replacement would only require a seal kit to complete the project.  Your information indicates a high amperage draw on the motor.  Does the amperage reading exceed the motor label specifications per the voltage connected?  If the amperage is higher than the maximum limit check the voltage at the motor power terminals.  If the voltage is low, the amperage draw will be increased to compensate for the low voltage.  Check for obstructions in the motor such as a worm impeller rubbing against the diffuser or debris wedged in between the impeller and the diffuser.

A  Answered on 1/12/2021 by InyoPools Product Specialist Megan C.

The Motor, 3/4hp Full Tristar 115/208-230v - SPX3207Z1BER is the suggested replacement with voltage options ranging from 115/208-230V with a total HP of 1.40HP, the Century 1.5 HP Square Flange 56Y Up Rate Motor - B2854 with a voltage of 230/115V could be used, based on voltage requirements you may require the SPX3207Z1BER. The label with C48D62A04 is suggested to use the SPX2707Z1M voltage options ranging from 115/208-230V, The SQ1072 with voltage options of 115/230V is the alternate option to the SPX2707Z1M. Again, depending on the voltage requirements you may require the SPX2707Z1M

Yes this B847 is the correct replacement motor for your 7-177474-01. When replacing your motor you will need a seal kit. For us to suggest the proper seal kit could you send a photo of a wide shot of your complete pool pump to show the pipes going in and out of the pump? Let us know if you live in California as you will require a different motor. To supply this photo simply click the reply link below and upload your photo. Once we get this photo we can make the proper recommendation for the seal kit.

    The existing one to be replaced is 3/4 HP, and the one you recommend B2853 is 1 HP, will it be compatible?
     Reply

    • Commented on 3/24/2020 by InyoPools Product Specialist Patrick P.

      Hi Ying, Yes they are the same True HP as your 3/4 HP is a full rate motor which is equivalent to a 1 HP up rate motor since the full rate motor has a higher service factor. This is easiest explained through showing the math... below is the comparison of a 1 HP Up Rate Motor Vs. a 3/4 HP Full Rate Motor.1 HP Up Rate Motor - 1 HP x 1.25 Service Factor (SF) = 1.25 True HP (THP) 3/4 HP Full Rate Motor - 3/4 HP x 1.65 Service Factor (SF) = 1.24 True HP (THP)

I just finished replacing the shaft seal on my booster pump. As soon as I turned the pump on water was leaking from the shaft seal. Is it defective or am I doing something wrong?
 Reply

A  Answered on 2/16/2012 by InyoPools Product Specialist Patrick P.

Depending on the model, the installation of a booster pump shaft seal can be slightly different than a pool pump shaft seal. Some booster pump and pool pump shaft seals require that a silicone sealant be used on the outer areas of the metal seat of the shaft seal. The seal will need to be lightly hammered into the body of the pump. You can use a 1 inch PVC coupling or a piece of 1 1/4 inch PVC pipe and a rubber mallet. This procedure will apply to any pool pump or booster pump using a >PS-1000 style shaft seal.

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?
 Reply

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?
 Reply

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.

It was easy to cross reference my old pump and find the perfect replacement match. INYO sent it out right away and I installed it easily. I like to watch their videos on replacing the pump and shaft seal first, as a refresher course, before I get started. Changing the pump and shaft seal is easy with their tutelage. Thank you INYO!

Shut off power. Disconnected power from motor and removed existing motor with seal plate from pump housing. Removed diffuser and then removed impeller. Removed motor from seal plate. Replaced shaft seals on impeller and seal plate. Reattached seal plate followed by impeller and diffuser. Reattached new motor with seal plate to pump housing and connected electrical. Super easy job and even easier following inyo how-to-videos.
