The water flow goes through the FIREMIKS water motor generating a circular rotor motion that is transferred to the dosing pump over the direct drive coupling. The concentrate is pumped into the water motor outlet, where dosing occurs.
Since the water motor functions both as a power source to the dosing pump and as a flow meter system, the system becomes flow proportional: dosing automatically follows all the variations in the water flow.


ENG - Basic function principleThe water motor rotor has 8 or 10 working wings, which gives an early and stable volumetric function of the water motor within a flow range up to 1:10 (for example 240-2.400 lpm). The narrow interior design along with the low friction of the vanes, reduces the noise level of the unit and creates a long and lasting durability.
