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.

I have an AO Smith Century Centurian 1 1/2 hp pump B128. Which shaft seal do I need?

A  Answered on 6/23/2017 by InyoPools Product Specialist Lennox H.

Hi, Lina. You will need to provide us with the model # of the pump housing in order to locate the correct pump seal.

Are the metal parts of this seal (PART#5250-100) stainless steel?

A  Answered on 6/7/2016 by InyoPools Product Specialist Alan M.

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