DMI with P3-System for the dosing of very small quantities. New pump solves old problem. ALLDOS has launched the DMI P3 system dosing pump for gassing chemicals such as sodium hypochlorite. This pump is capable of dosing amounts from 0.3 l/h up to 5.2 l/h. In connection with the Etron electronics with stroke frequency control, it is possible to reduce the dosing flow down to approx. 0.05 l/h whilst retaining accuracy.
