Was wondering since brewing and soda share a lot of the same equipment. Does a march pump and a soda pump do the same thing, or is there a difference. Currently I just brew extract but I am trying to research to build a system was curious?
The march-pumps we refer to can pump boiling liquids and are considered food-grade equipment. While the soda-pump may be food-grade I don’t think it can handle the high temps we deal with.
I am not exactly sure what you are referring to as to the soda pump. Awhile back, I was given several of the pumps that are used in the dispensing systems found at fast food restaurants. These pumps are air driven, most likely CO2. I tried to use them for hot wort transfer and they completely failed. They could not handle the hot wort.
