Will this motor work on a Jandy JHPU1.5

A  Answered on 11/22/2022 by InyoPools Product Specialist Hector F.

Hello Jeff, the direct replacement motor for the original Jandy pump model JHPU1.5 is the B229SE. We also recommend replacing the seals and gaskets when replacing a pool pump motor. For your series pool pump that would be the GOKIT77

Do I need and an O ring kit to switch out this pump this the old one. The bearing is going out on my sta-rite max-E-pro pump P6E6E-206L. I live in CA a have to deal with tile 20.

A  Answered on 7/22/2021 by InyoPools Product Specialist Craig C.

Hello Timothy.  It is recommended that the motor shaft seal, seal plate o-ring, and diffuser o-ring be replaced when replacing a motor.  The GOKIT79 contains the parts recommended to complete this project.   Tune Up Kit Sta-Rite Max-E-Pro (Pre February 2015) - GOKIT79

Century 1.5 HP Round Flange 56J Dual Speed Full Rate Motor - STS1152R ... My data plate matches exactly why would I need the Hi low switch... ? I have a control box that has that and my current motor does not but it is 6 years old.

A  Answered on 7/16/2021 by InyoPools Product Specialist Craig C.

Hello Carl.  The Hi-Lo switch is made available for those installations that have no other means to transition the motor from high speed to low speed.  If your current motor's data plate matches the specifications of the Century Motors model STS1152R, then it is the correct replacement motor.  If your current motor is functioning at its dual-speed capacity, then there is no need for any additional device with the replacement motor.

Can you tell me the GPM rating on the low speed 1/4 HP setting vs the high speed 1/5 HP setting?

A  Answered on 5/2/2021 by InyoPools Product Specialist Danny R.

Hi Mike,The GPM is not just dependant on the motor.  It really depends on what pool pump the motor is attached to.  So the impeller, diffuser etc will also have an impact on the overall GPM of the pump.

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.

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.
