I don't know much about how to post things on this site but I use a syrup pump just like what you have. I actually purchased the pump you bought but bought another (identical just a different brand) at an auction. It works great for mixing and dispensing syrup. I have only used it this season and haven't mixed more than 1:1 so can't comment on longivety or how it handles thicker syrup. Send me an email or phone number and I will send some pics of the setup.
