Have Screw Pumps ever been tried for this application?
https://en.wikipedia.org/wiki/Screw_pump
only 3 parts, no pulsation.
The piston pump can be powered by the gas pressure from the gas
generator. Looks like the screw pump requires either electric motor -
with heavy batteries - or a gas turbine, which could be more complex.
Everybody has their own preferences of course, somebody would prefer
electrical power, somebody would have no problem making a turbine, and
somebody would deal with pulsation with some bellows.

As I understand it, they're typically pretty heavy for the flow rate.
How much you care about that depends on the application.
stationary use, cast iron parts and thus heavy.
As nothing is reciprocating dumping mass is of no interest.
I like the parts count :-)
