If you've ever wondered about the purpose behind the filling system named The Bulkfiller, go to Sia's interview of Francis Goossens and scroll down to: What inspired the design of the Bulkfiller and what are it’s key design features? I was pleasantly surprised to learn his goal was more than just increased ink capacity, but rather eliminating shortcomings of existing filling systems. He wanted:
A- High ink intake
B- Allow the integration of an ink shut-off valve
C- Easy and efficient flushing in one or two actuation strokes.
D- Filling in one filling movement.
E- Postive displacement filling system

He also resolved to eliminate what he calls "stick-slip," a problem suffered by piston-fillers.
To the Conid users: Do you believe Francis has succeeded or failed in all or any of his goals? Have you found drawbacks in the Bulkfiller (other than price)?
