sedra 5000 same as 7000?

[foreverfortune]

im thinking that it is the larger and not the smaller sized ones. it has more of a rounder apperance and not of the squarer ones.

question: does the a or p at the end of the model number make any difference? or is the attachments that are included the only difference between them. for example sedra ksp-5000a and ksp-5000p? thanks

ok picked myself up a 7000, it is identical to the 5000 i have, even the impeller is the same size, just need to pick up a needle wheel modified one. from OA

only problem i have is the output union on my pump is glued on and cant be taken off. the intake has a volute that can be interchanged. anyone know where i might find this particular union that euro reef uses on their RC135 skimmers?

i have the old style union anyone know where i might find them locally? thanks

How do you get the impeller out... can't you switch the entire piece that you take off to remove the impeller?? I'm confused?? Where is it glued?

Ok cancel that... I think I had input and output confused. I now see your problem
