Yep. Doesn’t belong in the room with your CLS, which probably doesn’t belong inside.
See:Cold ethanol pumps for an exploration of more appropriate pumps.
The 8gpm fuel pump documented there would get the job done.
Can’t currently locate the original attribution for using the ECO brand mag drive pumps…might be in the thread linked above or one of those linked to/from it.
It relies on a couple of things
- at dry ice temps, ethanol is really hard to set on fire
- with dry ice, you’ve displaced the O2, so no fire
- even if you got ethanol(iso/methanol) in the pump, it’s submerged, so no O2, so no fire…(see 2 above).
