Hardware For Pumping Seltzer

To pump seltzer you can't use a peristaltic pump because it flattens the seltzer. There are some ways to pump carbonated beverages. I considered two: One of them is to pump flat liquid and then carbonate it like a soda fountain. I will try the second method first since the parts are cheaper for a simple prototype and less prone to catastrophic failure.
