4 – PUMPS AND BY – PASS
A standard vibration pump is used, also adopted on the
base Brio, and fitted with overheating protection;
however a by-pass pre-set at 10 bar is installed, to
avoid un uneven use of the coffee pod and thus
ensuring better dispensed product quality.
To ensure greater pump reliability and better tightness
against the pressure, a check valve was added at the
boiler inlet, this way no anomalous leads are exerted on
the pump when idle.
Also the pump is fitted with a check valve, thus ensuring
optimum tightness against the boiler internal pressure.
