Ok, So Memory/pages\sec
That's the count of hard page faults (page faults/sec are soft page faults). That's to do with pages that are in virtual memory but not physical memory (ie are in the page file)
SQL shouldn't be using the page file at all, unless it's getting paged to disk by the OS, so those will be from apps other than SQL on the box.
