Can you say: Cavitation

[michael950]

Do we see any symptoms of cavitation?

[Matt_E]

I don't think the stator damage is cavitation related...but I may be wrong.

I posted some great pics of cavitation destruction of a stocker SJ aluminum impeller over at PWCT a while back. I should dig up those pics.

Ugly, for sure.

I'm curious if anyone knows how cavitation would damage the stator veins .
Looks pretty bad though :aargh4:

[michael950]

I actually posted multiple pics (of pump) to link in an email to Dave @ impros. The cavitation I was referring to was on the Impeller.

The stator damage was most likely from the previous owner, one on the blades on the impeller has a big rock ding... draw conclusions here.


I think the impeller is stock, so I will be replacing it.

[Matt_E]

That does look like a cavitation damaged aluminum impeller, indeed.
The one I had was about three years down the road from that -already bad - state. It had holes eated just about through the hub. :bigeyes:

I have seen much worse...

Here's the link to my cavitation thread, with pics and tech info (http://www.pwctoday.com/showthread.php?t=41848&highlight=cavitation)

I had one one time I could almost see through :bigeyes:

Cavitation might eat stator blades at some point, but not like rocks will :wink:

[Matt_E]

:haha:

[LBE]

hows this? not just on the hub, the whole blade is trashed, all of them!

[Matt_E]

Nice...mined looked similar to that.

[Wattage]

It looks like you had a good time trying to get that of the shaft as well!

[Matt_E]

Notice it's not off the shaft yet.:biggrin:

[romack991]

wow, just reading your old thread matt...

i was/am a geek. good thing im outta college now and have forgotten all about those nerdy definitions and equations.

[LBE]

Yup it's still on there. I kinda gave up on it now. I needed a Blaster drive shaft and bought this one with the understanding it was correct. Well look at the pic, it's a 144 pump, but the shaft is longer than the Blaster's.

Any idea what this other one is for??

Anyone?

Anyone?

Buler?

[michael950]

Send the old one to impros... (get well impros... Please!)

[Prem1x]

LBE,

SJ= 26"
WB1= 28 3/4"
WB2= 27"
Raider 701= 33 3/4"
Raider 1100= 36"

Michael, those stock stator veins need some cleaning up. Did you send the pump off to be blueprinted, or are you going to grind it yourself?

[michael950]

Have not yet sent it off. Sent an email to Impros about getting it taken care of, but recieved this yesterday:
