I don't know about Flometrics piston pump, can you tell more?
Piston-LESS
A Google search for "Flometrics pistonless pump" will yield a ton of material
with enough detail to build one. It's a clever design. The pistonless pump
appears moderately easy to fabricate.
To me... the downside of the pistonless pump is the requirement to have a tank
of high pressure gas drive the pump (N2, CO2, other). Once the tank/GSE/etc
have been designed, does the pistonless pump offer any advantage over pressure
feeding the propellants? Don't know.
