Vibration pumps are primarily installed in household machines. They are somewhat louder and significantly cheaper than rotary pumps.
Two-circuit machines are robust, practical machines that allow simultaneous milk foaming during espresso extraction. They can also deliver several beverages in quick succession without a significant drop in temperature. Perfect for espresso lovers and fans of foamed milk.
