Crazy Idea

Positive displacement pumps! Has anyone tried using one? Just dial in a flowrate and hope your fittings don't blow off! Maybe a small Wankel rotor operating as a pump...or a dual rotor setup in parallel to smooth the flow.

Just crazy talk, I guess. Still, it does bring up funny mental pictures of some guy ripping the 13B out of a junked RX-7, converting it to a pump, and stashing it under his desk to run his rig.

been there done that. good try though

uuhh... aren't those like 1000gpm; 1000psi?
you'll need to switch to thick copper tubing, thats for sure.

Kind of a cool screw-type pump Cathar had there. Wonder if he ever ran a loop with that sucker.

Too practical, though. I like the sheer craziness of using a sportscar engine as a pump.

All he had was a picture. And it wasn't even a picture of a real pump, it was a mock-up.
