"pound" is a verb form of "to pound" here.
It is the same construct as "I felt a bee sting me".
The core part means "He felt a fury pound through his body, a fury that was not his own".
I'd use "rush" instead of "pound" here maybe, because furies tend not to move in one's body in much of a pounding manner.

The answer by Harper provides an excellent technical analysis.
For simplicity, the problem of comprehension can also be resolved by the minimal use of punctuation for clarification: "
He saw a large shadow and felt a fury that was not his own, pound through his body".

As a result, I would not want to translate an English document into German.
