The guy who invented a piston pump was Dr Steve Harrington of Flometrics. When
I knew him, he also taught at UCSD & San Diego State. Steve published a few
AIAA papers on the pump.

Is the question about a piston pump?
A guy invented it in a rocket club somewhere in southern CA about 10 years ago
and test fired it with a LOx/Kerosene TCA at FAR.
It worked, just bulky.

I'm researching that piston pump project, and can't find anything from
LLNL after approx. 2005 :( . Did they stop working on that?
Yeah, I don't recall seeing anything new from them in a long time. Most
likely, they simply ran out of funding, given the lack of funded applications
for the technology, and the general impoverishment of LLNL after the end of
the Cold War.
