Looking for hydraulics pump

Hello
The hydraulics pump on my 1993 XM 2.1TDI is very weak and needs to be replaced.
Are there even new ones for sale? If not, then used works as well.

Btw, a quick question - is hydraulics pump same as power steering pump? And how do I know which ones fit my car? I can see there are a lot of different ones that work, but they have different measures.

How do you know it is the pump that is faulty?
Before condemning it, ensure the suction hose is not leaking air in, the regulator isn't leaking pressure away, either via the bleed screw, or internal one-way valves and possibly most likely, the Lhm is clean and the filters in the reservoir are both clean. A dirty suction filter can significantly reduce the pumps ability to create pressure rapidly.
The pumping elements don't normally fail. Pressure is lost due to the one way disk valves failing to seal properly. Stripping, lapping and rebuilding can be a fix.
All the hydraulics, steering, brakes, suspension, are powered by a single pump
