Or derusting a petrol tank.It's good for cleaning the drains.
That looks very much like a 3 ton Machine Mart one, so the parts list picture might give you a clue as to the pump body layout...A mate left this with me as spares / repairs..
seems to be a well built unbranded 2.5t jack, problems are a stuck valve in the body and stripped splines where the lock / unlock shaft fits inside the handle.

Any suggestions why the valve has stuck or how to free it?
I was using it and the valve was ok, mate used it and now it’s seized. We tried hammering the toothed cog to free the valve but it’s not moving.
Keep it unopened or drink it?
Use it as rust remover ?
