This is indeed a SALAMI 2PE4.5D-G28P1, so it should serve as a direct replacement if that's the exact part you're needing.

That portion of the model designation identifies it as a Salami gear pump with a 4.5 displacement rating in the 2PE series. The "D" indicates the specific configuration within that series. Salami uses this naming convention consistently across their gear pump lineup, so once you know the pattern it makes ordering replacements a fair bit easier.
