So we are having fun today. I've got a 9 year old Whisperflo DS that had gotten noisy and finally quit working, I bought a replacement motor and tune up kit with seal and o-rings from Inyo. Well, as I've got the thing tore down and ready to rebuild I see they sent the wrong tune up kit. I see they have one at Leslie's (quite a bit cheaper as well surprisingly) but it is the "regular" kit and not the saltwater kit that I bought. Now that I am thinking about it, Pentair doesn't have a saltwater version of their pumps, so either the new ones all ship out with the saltwater parts or they all have the regular parts. My question is this saltwater kit thing bogus?
 
Salt or SCS are way better.. Here is a sheet of what takes what..

I think this is your pump??

Yes its a Pentair pump. Dang that PS 1905 seal is expensive. $83 on eBay and $104 on Amazon. The standard seal is PS 1000, I would imagine that is what the pump came with and it lasted 9 years. Looks like the ps 3865r is $15-20 so that is doable.
