Bobcat S185 can hydraulics/flow GPH be upgraded?

Yes, it's good to keep them all in mind.
Both GPM and PSI are important when rating a hydraulic system.

The formula for hydraulic HP = GPM x PSI / 1714.
1845c - 16 gpm x 2300 psi / 1714 = 21.47 hp
s185 - 16.9 gpm x 3300 psi / 1714 = 32.54 hp
s650 - 23 gpm x 3500 psi / 1714 = 46.97 hp

You can see from the examples, even though the 1845c & s185 flow nearly the same, the s185's hydraulic are much more powerful.
PSI is important too, not just flow.
Also keep in mind the HP of the engine too. Many are limited to 74 hp. It's driving the hydraulics.
I've see some machines where the hydraulic HP is almost equal to the engine HP. That isn't realistic.
Once you factor in friction losses, you'd end up with 0 usable hp to actually move the machine.

That is pretty cool stuff to know thanks for sharing! At least now I will not be totally oblivious (maybe ) when looking into machines and mulchers.

Thanks!
