Is there a way to rebuild a hidraulic pump?

I have an old BX pump laying in my garage that i think has a lot of dirt in it and was leaking when it was in my last BX, is there a way to open it and rebuild it or atleast clean it and fix the leaking?

I tried once [:(]
nope - not by normal DIY means [xx(]
1) special tools needed to remove the drivebelt pulley not damaging it ...
2) removing the housing from pump body. Can be done by carefully applying moderate pressure to the feed hose stud - from another pump.
3) finding new piston return springs. No spares available. MUST be replaced once pump is disassembled - or the whole job is a lotteri.
O-rings and bearings I believe would be possible to source from machinery shops.

So, what you are saying is if it's broken toss it...[:)]

IIRC, the Autobooks DS manual has disassembly instructions and lists part numbers for the springs etc. Doesn't mean that they're readily available, of course

Strangely the rest of the hydraulic system is very repairable and Citroen will supply bits. They must have intended that the pump wasn't - but don't really see why.

Given that exchange pumps are available (via our kind sponsors here) they must be repairable, but reconditioning needs some reasonably serious engineering know-how and tools, I suspect.
