Regner makes a pump with 5 mm piston: http://www.regner-dampftechnik.com/product-page/servo-pumpe-ohne-servoelektronik
If you discard the servo, the pump itself is very small and detailed, would fit a steam engine quite well.

Hi Calin, and as you say .. .."Regner makes a pump with 5 mm piston" .......

Pretty sure Bernhard has or had one of those installed in a clinker boat...but the constant rotational  squeak scared the fish away
