Hello Eddie.  Yes, this is the correct shaft seal for the Seal Plate Kit C203-193P.  Please note that the C203-193P Seal Plate Kit contains a shaft seal, seal plate, and seal plate o-ring.

Will part # 5250-100 work with a CHII 1 hp pump and a VGreen variable speed pump?

A  Answered on 5/11/2021 by InyoPools Product Specialist Robert M.

No, this would not be the correct shaft seal for a Challenger CHII pump. You would need the 5250-104. If you have salt water or want a heavy-duty seal, use part number 5250-210.

Does this deal fit Sara-rite P2RA5E-181L pump?

A  Answered on 11/5/2020 by InyoPools Product Specialist Hector F.

Hello, yes this shaft seal is compatible with the Sta-Rite Dura-Glass/ Max E Glass pool pump manufactured prior to 1998. One way to tell if it was, is if the seal plate has the copper or steel insert in it where the shaft seal sits. If there is no metal insert there then you can use the shaft seal part number 5250-104.

I don't know if my dura-glas is pre or post 98. The pump model tag was painted over. It has an A.O. Smith C48J2PA105C1 motor. Do I need this pump seal or the new style?

A  Answered on 5/14/2019 by InyoPools Product Specialist Hector F.

I would just use the new style seal and then remove the copper cone insert that would be in the seal plate if it is an old generation model. That would allow the new style seal to fit properly.

I am looking for a shaft seal that fits a Doughboy Powerline pool pump, model # 0-3047-200. Do you carry this or do you know where I can find one? Thank you!

A  Answered on 6/1/2018 by InyoPools Product Specialist Lennox H.

Hi, Ray. This Pump Seal 100 - PSR100 will not fit the Doughboy Powerline pool pump. We do not carry a pump seal that will fit. You may need to contact DOUGHBOY @ 866-DOUGHBOY.

The retaining spring and its frame on the shaft seal is a stainless steel skeleton.

Step 1 Go to local pool store and get told the motor is bad and you might as well replace the pump as well... That will only be about $600.

Step 2 Check out and enter in the relevant data. I found all the parts I needed and dropped them in the shopping cart... but wait, do I need this other gizmo???

Step 3 Chat with They looked at my shopping cart and ensured I had the right parts for my pump and I was now 100% confident.

Step 4 Parts arrive and I am ready to get to work.... but this pump seal, what side faces which way.

Step 5 Watch videos on how to install a pump seal.

Step 6 Called and the guy checked the part and the motor and we scoured over the exploded diagram and he explained to me how to install the pump seal.

Step 7 Installed pump seal and motor and plumbed everything back in. No leaks, no issues, no problem!
