I have a relatively new Simpson power washer that through much ignorance I destroyed the pump. I already replaced th pump and I’m back up and running. The pump is a AAA tri axial pump that I ran dry. Is the old pump rebuild-able or junk?
Power washer pump- rebuild or garbage?

are you able to source parts for it? probably not ... or,
I remember watching a you tube video some while back, and the author said the parts were almost as much as a new pump so it was no cheaper to rebuild. I guess you have to try & source the needed parts & decide from there

Tear it down and see what tore up, at worst you won't be able to source what you need and junk it anyways. Meanwhile - you'll learn something through the process.

If the pistons or bores are scored, it's junk.
Yeah, I’m pretty sure it’s junk. It was pushing pieces of junk through the hose. And clogging the nozzle

What kind of "junk" ? Sand/dirt ? Metal ? If it was "organic" you may have just clogged a passageway.
Just went through this with an AR pump. Seals and check valves were short money, but two of the ceramic pistons were cracked. Was about $400 in parts for everything. I must of let it freeze, only reason I fixed it was I know the pump has low hours. And the replacement was still more money. 4k psi at 4gpm.
It was pump pieces. I pulled the body from the pump and there was signs of destruction/ springs and plastic

AR RRV 4k psi 4GPM pump can be had on Pressure Washers Direct for $325 with free shipping for just the pump or $400 fully plumbed.
It's an RKV4G40, was still cheaper to rebuild, I was seeing them for $600+

Curious how stuff got in there for my own knowledge? If it's a good engine is there a way to put a better quality pump on it, like a cat pump? I bought a pressure washer 15 or so years ago with a honda engine and always thought about if the pump died looking into putting a quality pump on it.
It’s got a Honda engine. The pump overheated because the water was off. I had a lot of garden hose connected and it sucked the hose dry. The o-rings melted in the pump. Again- it was my fault. I had water coming out of the PW for several minutes but it wasn’t enough to keep the pump cool

Late to the game, but I'd suggest a new pump. Cat makes good pumps. I am OC about pump care:
- Winterize with pump saver before long term storage
- After every use, with engine off and everything disconnected, tip and slowly pull starter to remove water
- Never run more than a minute with wand off
- After use and engine off, activate wand to flow cool water through pump for 5 minutes
- Check hose screen before use
- Flush air out of the intake hose with engine off, sometimes run for 3-4 minutes if the hose is long
- Change pump oil as directed
