working principle and fluid flow
The principle is basically as a bicycle pump: the pump (03) goes down which creates a
depression in the piston volume. Due to this depression the colorant will pass from the canister
through the filter and the three-way valve (02) to the piston. When the piston goes up it will push
the fluid back to the canister (in recirculation) or it will go to the dosing head (04) passing
through the three-way valve.
