    Default SS Impeller problems - HELP

    I have a Berkeley Stainless Steel impeller, and I was having it cut from an A to an AB, and a crack was discovered. See the pics. Well the issue is the back side has a huge casting flaw. Has anyone ever encountered this? If so, what did you do, and who did it? Any and all help is appreciated...

    IMHO I would start over and scrap this deal, not worth the risk...

    Right now I have a worked GTH "A" stainless, the difference from the GTH to the Bekeley is friggen spooky, good luck.

    Lock.....I don't know that much about jets except they spin very fast, never the less....I'm afraid if we were to weld this it would crack behind the weld......I mean I'm kinda with GT, I'd be real leary of spinning this deal this fast like you guys do. Is it something you recently purchased? Or is it something else. I'll try anything but I'd hate to see you destroy your pump. Bring it this weekend if possible so we can look at it in the light. Flaws usually mean there is an impurity in the metal, It will be exagerated <sp> by welding......

    Hopefully I'm wrong, I know these impellers are'nt cheap. Like I said, bring it and we'll figure it out.

    Send it to MPD and let Jack work his magic. It is fixable. Mine was cracked in 5 spots and he did it up and its better than new.

    Whats the differance? Its a direct copy of the Berkley isnt it. I run the same impellor (GTH). I have no issues with mine... Its lightened, detailed and balanced...It leaves Hard!

    The casting on my GTH is twice as nice as my Berkeley, the GTH has been balanced and polished so its very easy to see how clean the cast was, the metal just looks cleaner IMO, the GTH is a nice piece and I was only using it as a reference.

    Why are they cutting on the front side, to make it an A/B?

    Like Futs said, the guy knows what can, and cannot be done, with impellers.

    I agree with you. The problem is, I bought it from a friend, and not directly from Berkeley.

    prob to repair the gash that rock made , would account for the cracks. a local buddy has a impellor with the frt cut on it and its shit outta the hole, i can swim faster.

    Dare to be different, if it turns out great you can claim you planned it that way.

    Per Jack at MPD, most all castings have some flaws. Any new part he gets has to be welded up before and during the finishing stages. He has welded them up for me, and no problems.

    Just my OP , I'm sure it could be sucessfully welded, machined and made "useable" I personally wouldn't condone use of it however (possibly low HP application) the front side crack is clearly a direct result of the manufacturing flaw on the backside of that blade , again just my 02 Tom
