Hydraulic pump help

[Nighthunter]

I'm looking at building a pto driven hydraulic wood splitter, I was given this pump recently, would it work for my application, it came from some type of drill rig. Any help on figuring out the GPM on it, it doesn't have much in the line of a serial number but has 28 Hb on it

I cant help much on the maker or gpm. Definitely appears to be a tandem pump not a 2 stage pump that alot of splitters use.

But maybe being a tandem pump would give some options for say a log lift or adjustable wedge.

I’d take it to a hydraulic shop, they should be able to flow/pressure test, something similar to a diesel injector pump. Id want to know if it was good before fabricating something up.

If you care you could tear it apart to math the ratio.
