The dosing pump is an intregrated part of
the coffee pack and can not be disassembled
or adjusted. It is a closed system to prevent
that air can affect the quality of the coffee
concentrate.
The dosing coil assembly is available
as a single spare part. The sub-parts
are not separately available.
2. Functional description
The coffee concentrate is delivered in a 1.25 liter/ 42.3 fl oz bag in box. It is a closed system with an
intregrated dosing pump inside the tube.
The pump is operated by the B2 dosing coil. A current of 5.2 A is applied to the B2 dosing coil to
generate a magnetic field that generates the pumping action.
