You could look on somewhere like ebay and see if there are any cheap second hand parts or whole unit you can cannibalize 

I've been in every nook and cranny there and the rest on the Internet.  I'm coming round to the idea that I should maybe replace the pump as the whole machine is over 12 years old.

Thanks very much for that interesting fix - well worth pondering.  I haven't taken them out yet but here's the combined unit:

I had a wee look on t'bay, and there was nothing useful on there. I guess you can expect any 2nd-hand spares to be quickly grabbed! 

The two mating parts have very distinct flanges that could well lend themselves to non-permanent fixes too. Something like:

You'd need to measure the combined thickness of the flange when joined, but in theory it would only require a couple of clips, since it's current only held at two points (tho' no harm in three or four, tobesure). There will almost certainly be a rubber washer in between that does the actual sealing, so a couple of such clips (I don't think that particular size is suitable, tho', as they are too long? It's just an example) should hold it quite securely. 

Or, bond it completely together.
