Air diaphram for cream machine?

[cjf12]

Thinking about making a cream machine but noticed all the ones built have gear pumps on them. Is speed a factor? Noticing gear reducers and what not also. Was hoping to capitalize on my diaphram pump on the off season. Thanks for any input.

I don't know, but my wonder is if an air diaphragm can handle that thicker consistency? I do notice if I try to pump syrup from a cold barrel at like 15-20F it does not do well, warm it to 50 and it moves fine.

I also have a feeling the gear driven action is the "agitation" in the cream making process. Again as mentioned not sure a air diaphragm pump will make syrup into cream?
