what product do you use to seal the seal plate so water does not leak out
 Reply

A  Answered on 5/3/2021 by InyoPools Product Specialist Danny R.

If you use a Seal Plate Gasket 357100 this will keep water from leaking out.  This gasket is used on this particular seal plate 074565

Looking to replace the seal plate and the O ring on our part 7- 177451-03. Picture attached. Can you help me.

A  Answered on 6/11/2020 by InyoPools Product Specialist Hector F.

Unfortunately, we cannot use this image as the seals and gaskets are actually based on the front pump wet end housing that the motor attaches to.

Hi Melanie, could you send us a few photos of your pump and motor? Please take a close up shot of the motor label as well as a wide shot of the complete pump to include the pipes going in and out of the pump. To supply photos simply click the reply link below and upload your photos. Once we get those photos we can make the proper recommendation.

I have a whisperflo wf-26 pump made before 2008 . I always have used the almond plate gasket which is for units made before 2008. With this new seal plate which gasket should I use, Thank you
 Reply

A  Answered on 5/20/2020 by InyoPools Product Specialist Hector F.

The seal plates manufactured before 1-31-2008 would be part number 5020-062 that you can view by clicking here. If you need to confirm date of manufacture you will need to provide the serial number to Pentair so they can advise. Their phone number is 1-800-831-7133 .

if i change seal plate 5074-18a from my 56y frame motor , with seal plate 5074-38 of a 48y frame, on my existing WF-12 pump housing, can I then add variable speed motor ECM27SQU and have everything else line up?

You actually would not need to change the seal plate, however, you may want to change the impeller to part number 5074-27D

how does the seal plate come off after you have disconeted the pump
 Reply

A  Answered on 9/2/2016 by InyoPools Product Specialist Megan C.

Hello, Richard. You will need to remove the diffuser cover and impeller first. I have included a link on How To Replace the Motor on Your Pool Pump http://www.inyopools.com/HowToPage/how_to_replace_the_motor_on_your_pool_pump.aspx The link is not specific to the Whisperflo, though, it will provide a general overview on how remove the parts.

I developed a small leak between the pump and motor. I ordered a seal kit and appropriate o rings in order to rebuild.

Written on 4/20/2020 by Guest

Ordered O'rings and appropriate seal kit to repair leak. Removed motor,when I tried to disassemble the seal plate, two of the bolts were corroded and when they finally broke free the brass inserts fractured the mount. I ordered a new seal plate, replaced the seal, reassembled the motor to seal plate (never seized all the bolts) and reinstalled to strainer assembly. Primed and reconnected the power. Energized the pump and all was fine. No more leaks to my 12 year old Intelliflo variable speed pump

Old Seal Plate Corroded

Written on 4/15/2019 by Guest

First the new ceramic seal is pressed into the pump impeller. Then the matching seal is pressed into the seal plate. New seal plate attaches to motor with four bolts that engage metal threaded inserts (these were corroded and wobbly in the old replaced seal plate).

Impeller is screwed into the motor shaft (holding shaft steady with small wrench). Then reverse threaded bolt is screwed onto tip of motor shaft (don't forget O-ring). Finally, use hex tool to attach water distributor to motor seal plate.
