Thanks @TheGratefulPhil

Diaphragm pump that can handle -80°C

https://www.nboler.com/collections/all/products/explosion-proof-transfer-pump-pneumatic It’s centrifugal, but it’ll go down to -100C. I still can’t figure out who makes these but the gals n guys @N.B.OLER seem to keep them in stock.

Apologies if it’s already mentioned upthread
