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
applications for the technology, and the general impoverishment of LLNL
after the end of the Cold War.
I don’t recall exactly when but Jordin left LLNL somewhere in there and I
think that there was no further piston pump work afterwards. He wasn’t the
only one on it for sure, but I think lack of funds and team breaking up
were interrelated.
My impression of that could be wrong, but I don’t know who we could ask
now to try and find out.
