Help with skimmer pump!

[NDIrish]

Need to replace my Atman PH3000 skimmer pump. The old one shows Qmax: 2880 l/h (760 gph). The new Atman PH3000 replacement pump shows Qmax: 3550 lph or 940 gph.
Do you guys think the difference will work?
If not what would you guys recommend?

I'd be more concerned that the "new" Atman fits in the same way the old Atman fit within the skimmer. I have an Atman in an old SWC Skimmer and would love to find a replacement that would fit....haven't yet, and I've been looking.

Thanks.
Saw on YouTube a man bought the replacement pump and compared the two together. The bodies are the same size and the external parts were interchangeable.
That's why I'm not to concern about the size and didn't bring it up. I was wondering about the gph.

Again, for me, fit first. The gph can always be "dialed in" with adjustments.
