8.0 - VOLUMETRIC PROPORTIONAL DOSING PUMP
Pump models: PB-F and PB-VFT.
In this series the pump is controlled by pulses emitted from a w.meter reed contact (K). The number of pulses is pro-
portional to the water flow point where the flow meter is installed.
External pulses reach the pump through the w.meter connector (F) and by a specific adjustment will inject into the
pipeline an amount of additive proportional to the liquid that flows into the line.
8.1 - PROPORTIONAL DOSING PUMP
This model can either works with manual or fixed proportional regulation: connected to a pulse emitting water
meter will give an injection for every pulse received.
