got a Permco 5100 series gear pump, is this end cover the right one if i need 1-1/4 NPT on both the inlet and outlet?

For a Permco 5100 series gear pump, this end cover is set up as a direct-fit configuration piece with 1-1/4 inch NPT porting on both the inlet and outlet, so it matches that port size and thread type on both sides.

How does this end cover fit into an existing hydraulic setup?

This Permco end cover is made to directly replace the same part on Permco 5100 series gear pumps, so swapping it in should be pretty straightforward. Just make sure you're working with a compatible 5100 series pump.
