Is changing a vibe machine to a rotary machine consist of changing the pump and adding a motor or is there more to it?
A1: No, see Do most plumb-in machines require external pressure? The Izzo Alex II, for example, has a rotary pump and switches between tank/plumbed-in.
A2: For the most part, yes. Vibratory pumps pressurize more slowly than rotary pumps, providing a sort of preinfusion I've dubbed "progressive preinfusion". Pressure profiles, preinfusion and the forgiveness factor elaborates on this point.
