Can anyone help me identify this pump?

This pump came out of a quite old Mode Aquariums skimmer. It’s a space saver skimmer with the pump internal.
Pump died. The skimmer was working great.
Hoping someone can help me identify this pump so I can order a replacement. Instead of replacing the skimmer.
There is no model number on the pump. I have no way of knowing or measuring the inlet/outlet. I am horrible at those things.

Looks like a copy of an older Red Sea impeller, and Jebeo controller, or hybrid technology probably infringing patents?
Not sure you can find a matching replacement, but the Reef Octopus bubble blaster pumps might work? The are expensive but work very well and very reliable over time, ime.

Yea figured its some knock off. From what I searched the simplicity 1000 pump looks similar. But I just don't want to take a risk of ordering a pump that wont fit and will be useless for me otherwise.
I can just buy a new skimmer before spending so much on a reef octopus pump which may or may not fit right.

Looks like I just may need to use a new skimmer.
I already ordered a RSK300. but was hoping to just keep it as a backup since my old one worked so well.
I also have an old tunze 9410 but its missing parts.
