I'm having trouble finding what type seal I should use. I will send photo of motor name plate. Motor is working fine.

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? To supply your photos simply click the reply link below and upload your photos. Once we get this photo we can make the proper recommendation for the seal kit.

Please click here to view the parts diagram for your pump. The GOKIT14 is the complete seal kit and key number 16 is the shaft seal which commonly is the seal that needs to be replaced based on your leak description.

is this seal applicable for salt water use

A  Answered on 2/6/2019 by InyoPools Product Specialist Lennox H.

Hi, Kenneth. It will not, the Viton Seal - PS-3868 will hold up a lot better.

Does this seal fit a Pentair Boost Rite?

A  Answered on 12/5/2018 by InyoPools Product Specialist Lennox H.

Hi, Rick. This Shaft Seal is not compatible with the Roost Rite pump, you will need part # ZBR43920.

I need a new motor and shaft seal or seal kit for my Pearl whirlpool, but I can't find the seal on your site. The motor is MagneTek .7 HP (1.0 SF) 7-177954-23 which I believe your BN24 will replace. The pump label does not list a brand name. It reads: 7JCM-TL-3-BULK, model 94216710, date 30OCT98. Can you please verify that I selected the right motor and tell me which seal will fit. Thanks, Danial

A  Answered on 6/20/2018 by InyoPools Product Specialist Lennox H.

Hi, Danial. Unfortunately, I was unable to locate the seals or seal kit for the pump you have. However, I was able to confirm that the BN24 motor is the correct replacement motor.

Hello Deryk, the part 7-184821-04 cross-references to 3 HP 2 Speed 230V Low Amps Thru Bolt Motor (3421821) - BN62. If you need shaft seal, we would need to know the pump model number in order to assist you with finding your correct seals.

?     Asked on 7/17/2017 by Tony

I have an AO Smith UST1072. I bought a PS-201 seal that doesn't fit the shaft. The original seal on the shaft had notches for two metal pieces extruding from the bottom of the shaft. Is the PSR-201 the correct seal for this shaft instead?

A  Answered on 7/20/2017 by InyoPools Product Specialist Lennox H.

Hi, Tony. You will need to remove that metal piece in order to get the new pump seal to fit onto the impeller shaft.

What shaft seal part should I purchase?

How to get pump separated from motor, I have a motor model s48874a03 and pump model jwpas5f-2a4

A  Answered on 6/11/2015 by InyoPools Product Specialist Brian M.

While this video and instructions are not for your exact pump, it still covers all the steps needed to remove a motor. Please click "How to Replace the Motor on Your Pool Pump" 

?     Asked on 6/10/2015 by brian

I bought this along with a motor. I have setup watching your diff videos. It is a JWPA Sta-Rite pump. After hooking everything up and turning it on, there is water coming from the backside of the impeller so the seal is failing. I did have a VERY hard time getting the seal onto the impeller and I'm not sure the spring is actually able to move properly. Should I lubricate the impeller to help slide on the seal, and if so, with what (not the seal itself, but the impeller to help slide on).

A  Answered on 6/16/2015 by InyoPools Product Specialist Lennox H.

Brian, Lubricating the shaft/inside of the impeller with a silicone lubricant where the shaft seal goes will make it easier to install the seal. You may need to install a new shaft seal since its leaking.

Which side goes where when I replace this 201 shaft seal?

A  Answered on 9/15/2014 by InyoPools Product Specialist Patrick P.

When replacing this 201 shaft seal as well as others you need to put the spring side on or against the impeller with the dark ceramic side out and then the other half of the seal inside the pump seal plate with the white ceramic side facing out. Please be advised not to touch, wet, or dirty any of the ceramic parts for it very well may compromise the seal.

Had to replace the motor

Written on 7/25/2019 by Guest

I never replce a pool pump motor. This was very easy to replace the seal. 4 screws pump comes out. Allen wrench a 22mm to losen the bolt on the shaft. Use a screwdriver to take the seal out press the new one in. Put it back. Done. 30 min job at most.

Were these instructions helpful?
