The main thing may be to find what is wrong with your original pump. The are firms out there, like BBA-Reman that can rebuild and repair any power steering pumps, especially electric ones
The other option is to find out is another pump is possible. The picture on the left is a late Clio electric pump, and the illustration to the right is the 610 pump. You will notice that, apart from the filling resevoir(which unbolts and can be changed)..the rest of the motor assembly, hose ports and aluminium mounting block, even the two rivits on top of the motor cylinder, are nearly identical, so it could be the same pump assembly.
...but then again, if it is the same, the Late Clio pumps have a known fault of failing by going open circuit, nothing mechanical, and this could be the same fault with the 610.
