If you can power a piston pump with gas pressure, you can power a piston
engine to drive a screw pump. :-)
I guess piston engine wouldn't have parts count advantages over piston
pump, but you're right - one can convert gas pressure to a rotary
motion without a turbine.

The piston pump can be powered by the gas pressure from the gas

with heavy batteries - or a gas turbine, which could be more complex.
