Russell McMahon, In 1698 Thomas Savery obtained a patent for "Raising Water by the Impellent Force of Fire" I found it in a booklet from the Science Museum of London "The Steam Engine" It is by no doubt a pistonless pump. Savary`s pump was build 300 years ago.

I think that, using the normal RM> meaning of the word, the still working Australian water pump may be RM> considered to have NO moving parts :-).
