It works with a vibration pump operated by an electronic that automatically adjusts the boiler level.
Before coffee delivery the pump fills the lever group providing a pre infusion between coffee and water.
During delivery the pump stops, and the pressure in the group unit is developed by two springs that guarantee a steady supply and the best oil extraction from the ground coffee.
The group is heated by an heating element that ensures the group thermostability.
