Videos | Ask the Experts | What's the Difference Between a Rotary and a Vibratory Pump?

What's a rotary pump? How about a vibratory pump? Is one better than the other? How do they work?

We answer these questions -- and more! -- in this video featuring our good friend, engineer Bill Crossland. Watch as he and Gail show internals of each type of pump and discuss how they function. Then Gail measures the sound differential between the two pumps and we pull shots from machines using them to test out if we can taste a difference.
