Overview: Rotary vs. Vibratory Pumps
Aside from a variation in sound, what are the differences between these two style of espresso machine pumps? Is one better than the other? How does their technology compare? Can you tell a difference in shot quality? We asked Bill Crossland to walk us through the technology and internal functionality of these two pumps, then we measure sound differences and taste shots to see if we notice a practical difference.
