Just for information I got in contact with Bravo pumps in Italy through this email address firstname.lastname@example.org
Got a reply asking me for the type of pump and what series it was, what parts I needed and what the quantity was for each part and they would supply a quote. Pulled it apart tonight and got a list together. They included a lovely exploded view schematic with all the parts numbered for easy identification. I will let you know what the prices are like when I get a quote.
Let me know if you want a copy of the schematic as it is 4mb so a little too big to attach!
